User questions & answers

Question:	Can I store the smaller, 1lb propane tanks on my terrace porch, possibly in a box, overall? in cold winters and hot summers
Answer:	For maximum safety, my recommendation is to store propane containers in a weather protected location, such as garage or shed with some natural ventilation. Propane is a highly flammable liquified petroleum gas that vaporizes and expands many-fold very quickly if released to atmospheric pressure, and will form a highly explosive mixture if released in a confined space without outside ventilation. If then ignited by a small spark such as a light switch, the resulting explosion may be catastrophic. There are on-line photos of boats that have exploded from propane leaks in the confined space of a boat cabin with catastrophic results including death of occupants. The cabin top and sides have literally been blown to pieces in such cases. New, sealed bottles of 1 lb size are reasonably safe, but once opened or partly used it is best to store away from occupied spaces. Although the probability is low, the consequences of failure are unacceptable. 20 lb propane containers should never be stored indoors. Play it extra safe and store propane bottles in a garage or outdoor shed. BJG (PE, ichemical engineer, inactive, retired)
Question:	can i hook a large propane tank to his
Answer:	Yes, any size propane tank can be a source for it when plumbed correctly. The simplest way to go is using the F273704 hose directly off most tanks. That hose needs nothing else and goes direct from the tank to the heater. This model heater only accepts high pressure gas thru the "disposable tank" connection, so other hoses with that connection can be used as well as the "filter" F273699. The "filter" is to take out oils coming from most rubbers in hoses where the high pressure "squeezes" the oil out, but the 704 hose is made "oil-free" to avoid that issue. FYI I tried running this off a regulated low pressure source, but with it on "high" the glow was like "low" setting normally (showing a lack of gas coming thru). So if you have a low pressure source, the "Big Buddy" models have a connection point for such thru a quick disconnect using hoses like F271802 or F271803, but not this model (this one needs high pressure gas to get enough thru it's disposable tank port).
Question:	How long with the heater run on low with a propane small cannister
Answer:	Best guess is 4-5 hours on low. I sat in a hunting blind for 2.5 hours and the 1lb propane canister was about half empty.
Question:	Does anyone know or understand how is it this type of propane heater can be used indoors without causing carbon dioxide poisoning
Answer:	As soon as the weather gets cold, I put my Big Buddy Heater on a stand & use a Mr. Heater 12' hose with regulator running to a 20lb. tank in living room. I use the hose with the low pressure regulator on it & hook it up to the quick connect fitting. I have 2 20lb tanks in mint condition, and rotate them as needed. This will be my 7th winter using it. Old windows & doors let air in and I have a carbon monoxide alarm near by. Also use a leak detector to check all connections after hooking up a full tank. If it's really cold, I'll start it on high for a short time, then run it on medium & it keeps living & dining room warm. Cuts my oil bill down greatly.

User questions & answers

Question:	Prod descrip states this model has a built in silent electric ignition, but one of the cust comments indicates it's a standard piezo. Which is it
Answer:	This unit has a push button ignition. Clicks and lights. Globaltowne is an Authorized Mr. Heater distributor.
Question:	When using this heater with a 20 lb tank, do i need a regulator on that tank and hose
Answer:	No, using a hose like the F273704 will go to the "disposable tank" port and that expects high pressure gas (just as from the small tanks). The "Big Buddy" models have a Quick Disconnect port that takes in low pressure gas (and needs a regulator like the F281703 hose assembly), but not this or the Buddy MH9B models. I even tried running regulated gas into the Buddy heater, but it would stay like on "low" even though I put it on "high" showing not enough gas flow. So anything with a "disposable tank" connection expects high pressure gas (no regulators).
Question:	When I put the heater setting on low, it sputters and makes a lot of noise, is this normal, but works fine on high. Thanks
Answer:	Mine does the same. However, I found if I just adjust the temp selector just a little above low, slightly increasing the flow of gas but nothing like the high setting, the noise goes away. I literally shot a 6 point buck at 30 yards with the heater running like that this year.
Question:	which hoses can you use to connect 20 lb. tank
Answer:	The F273704 can be used alone. Many other hoses from mr heater (like F273701, F273702, F273703) and others can work that go to the "disposable tank" connection, but you'll need to add the "filter" with those others (item F273699). The reason for the filter is to catch oils that get "squeezed" out of most rubbers in hoses where the oils mess up the heater, but the 704 hose is made "oil-free" to not need it. Those are the choices for this model.
Question:	Can the 2 heating heads be rotated and if so, independently of each other
Answer:	They can be rotated independently
Question:	do you need electric to ignite
Answer:	You do need thumbs, but no electricity.
Question:	The burners light but switch off after i release the safety shut off valve plunger, no matter how long i keep it pushed in. it should stay lit
Answer:	Not sure if you have your problem fixed yet. But I had the same problem awhile back. I pushed the sensor probe closer to the heat element. I was too far away to stay heated and keep the unit on.
Question:	How long does a normal supermarket propane tank last with this unit
Answer:	That depends first I have no idea what a "Supermarket propane Tank" is, if it is a standard 20lb propane tank which you see on every gas grill and on this illustration then I can answer that question. 1 gallon of propane weighs 4.2 pounds, a 20 pound tank weighs 17 lbs empty and 37 lbs with 20 lbs of propane in it, a "full" 20 lb cylinder should have 4.7 gallons or propane in it.Now we have to discuss this model of Mr. heater which has two burners, you can run it on one or both and you can set it for low medium or high which is many differentt total burn times, I will assume either one or both with no mixture of settings.Single burner approx. operating hr.: 52/Low 37/Med 30/HighBTU output: 8,000 12,000 14,000Double burner approx. operating hr.: 25/Low 18/Med 15/HighBTU output: 16,000 24,000 28,000

User questions & answers

Question:	I ordered one of these but can't seem to find info on how it actually hooks up to the propane tank. Also, does it come with a tank
Answer:	It does not include a tank. You can get a Mr Heater hose that is 3/8 npt on one end and a tank fitting on the other end. The inlet on the heater is 3/8 npt.
Question:	Can this heater run with only the pilot flame on
Answer:	It is self-contained and automatic. The pilot setting will keep only the pilot burning. In heating mode it will automatically turn on and off at the desired temperature. The optional fan is not required but does not need to be plugged in if installed.
Question:	Does this have plate for built in fan
Answer:	Yes. Also wired for the fan so it is thermostatically controlled. Fan sold seperately.
Question:	How low can the thermostat be set? Can it keep a room just above freezing
Answer:	I use it to supplement my forced air heat. I would imagine in a room that is prone to freezing with the unit on it's lowest setting it would cycle quite a bit. It definitely kicks out a lot of heat.
Question:	How long will 20lb propaine last on lowest setting in insulated room
Answer:	Say a 10' x 10' room; about 12 to 16 hours. You MUST have some fresh air coming into the room or the O2 depletion will shut the heater off. Propane need air to burn just like most flames.
Question:	Is this safe in a 300 square foot cabin as the sole source of heat
Answer:	This is very large for a room of that size. I would recommend the 20,000 BTU model. That is ASIN B01DPZ5B3. These are designed as supplemental heat but it could be used for your application.
Question:	Does this product have built in regulator
Answer:	You must use an external regulator. You need some other hardware if you are going to use it on the floor. Here is what you need: ASIN:B0002YPAFY Rectorseal 23631 1/4 Pint Brush Top T Plus 2 Pipe Thread Sealant, ASIN:B0058DIGPU Anvil 8700137808, Steel Pipe Fitting, Nipple, 3/8" NPT Male x 4" Length, Black Finish, ASIN:B005R21QLS Mr. Heater 12-Feet Hose/Regulator Assembly, P.O.L. and Hand Wheel x 3/8-Inch Female Pipe Thread. If your heater did not include an elbow, get a 3/8" ASIN:B005C2U67I Anvil Malleable Iron Pipe Fitting, Class 150, 90 Degree Street Elbow, NPT Male x NPT Female, Black Finish. Put sealant on the outside threads only. Screw the elbow into the heater so that the opening faces the front of the heater. Screw the nipple into the elbow. Attach the feet that came with the heater. Screw the hose onto the nipple. Attach the other end of the hose to your propane tank. Check all connections with soapy water before lighting.
Question:	Will this burn in high elevation
Answer:	Yes as long as there is enough oxygen. Oxygen above 12000 feet altitude becomes thin and supports combustion less efficiently.

User questions & answers

Question:	Can you use gas station diesel with this heater
Answer:	You are able to use diesel #2 with this unit.
Question:	Can this heater be used indoors without venting when using diesel? I have seen mixed reviews on the odor when using diesel but more opinions are nice
Answer:	I use one indoors in a 1900 ft2 shop. Mostly I use diesel fuel but ignition with straight diesel is problematic with this and most multi fuel units. Diesel actually burns hotter and cleaner (less smell) than kerosine. I mix about 3 gallons of diesel with 2 gallons of kerosine. It a hotter cleaner burn that costs a lot less than straight kerosine.
Question:	Does this use a wick like smaller kerosene heaters do
Answer:	No, totally different burner type. It uses a powered pump/burner assembly and blows heat out one end, brings in burner air from the other end. Called a "salamander" heater in the construction trades. Also is MUCH noisier than a wick type heater!
Question:	How long does a fill tank last
Answer:	About 6 hours. Takes a tank and a third to run a 9 hour day.

User questions & answers

Question:	Does this one have a thermostat n blower
Answer:	Yes a blower and a thermostat.
Question:	I would like to use this at a cabin that is at 10,750 feet above sea level. Most appliances have to be ported differently. Will it work
Answer:	Yes but the mfg discusses elevation in the paperwork that comes with unit. I would call them
Question:	The specs do not list a blower. blower is mentioned is in the q&a section only. does it really have a blower? if so, why isn't it in the specs
Answer:	Thank you for your inquiry. A passive non forced air blower is available with all our vent free heaters 20K or larger. It is a purchase ad on.
Question:	How long is the blower power cord
Answer:	About 5 feet
Question:	Where do i buy natural gas for it
Answer:	You tap into an existing gas line
Question:	sq ft insulated garage (including garage door). Would this take care of warming up the garage
Answer:	I believe that it would. I have it in a 200 sq ft room with 13 ft ceilings, the house is 118 yrs old w/no insulation and it works very well. I do have the bigger size in another room.It has 3 burners instead of 2 and you can turn on 1,2 or all 3. It heats 2 rooms I have.
Question:	Is it possible to use with a thermostat rather than the low and high settings
Answer:	The heater is not designed to be used with an external thermostat.
Question:	How are the fumes vented ? I don't understand how you can burn something and not have to worry about carbon monoxide
Answer:	The fumes are not vented. Natural gas is mostly H₂, gasoline is about 50% carbon, coal is all carbon. So being mostly H₂, the combustion products are mostly H₂O with a little CO₂, not unlike what we breath out. Coal and gasoline will asphyxiate you fairly quickly because of the high carbon content, which must be vented outside.

User questions & answers

Question:	Does this hook up to my natural gas system or is it just for use with 20 gallon tank you buy
Answer:	Not for natural gas. hook up to LP, any size tank. ours is hooked up to outside 100 # tank.
Question:	Can the fan be used if mounted on wall
Answer:	Yes. I have mine standing on the floor but it came with the hardware for wall mounting. The hardware included spacers so the fan will be able to breathe. However, the fan does require to be plugged in so you need to mount close to an outlet. The heater itself has a battery ignitor so it can be used during power outages.
Question:	Is anything else required for use with this heater? How does the propane hook up to it
Answer:	You will need to buy a hose and regulator to hook up to a propane tank. You will also need some adapter fittings for the gas line since the fitting on the heater is a 3/8 NPT and the typical hose has 3/8 Flare fitting. You can get a universal Gas hook up kit that has all the adapters plus a shut off valve. The shut off valve is critical if it will be hard lined into a gas system instead of off a separate tank
Question:	Does it have legs to set on the floor
Answer:	Yes, you have to attach them - very simple and only 4 screws. Very pleased with the Heater though I added a blower and the auto temp switch functions improperly.

User questions & answers

Question:	Where do i buy natural gas for it
Answer:	You tap into an existing gas line
Question:	sq ft insulated garage (including garage door). Would this take care of warming up the garage
Answer:	I believe that it would. I have it in a 200 sq ft room with 13 ft ceilings, the house is 118 yrs old w/no insulation and it works very well. I do have the bigger size in another room.It has 3 burners instead of 2 and you can turn on 1,2 or all 3. It heats 2 rooms I have.
Question:	Is it possible to use with a thermostat rather than the low and high settings
Answer:	The heater is not designed to be used with an external thermostat.
Question:	How are the fumes vented ? I don't understand how you can burn something and not have to worry about carbon monoxide
Answer:	The fumes are not vented. Natural gas is mostly H₂, gasoline is about 50% carbon, coal is all carbon. So being mostly H₂, the combustion products are mostly H₂O with a little CO₂, not unlike what we breath out. Coal and gasoline will asphyxiate you fairly quickly because of the high carbon content, which must be vented outside.

Radiant Vent Free Heaters

Our Vent Free heaters need no external power, great for power outages and applications with no electricity. They can be mounted to the wall with the supplied bracket or on the floor with the supplied feet.

Most common uses are rooms that don’t warm well so you can adjust the temperature level in them without having to affect the rest of the home.

There are two types of vent free heaters, blue flame (or convection heat) and Infrared (or radiant heat). The difference in these types of heat are how the warm.

The Infrared heater warms objects. It doesn’t warm the air like a Blue Flame. It can be put in an area with objects which the heater will heat and then the object will heat the air. Blue Flame warms the air, infrared warms objects, which heat the air.

Note: Units cannot be converted from Propane to Natural Gas and vice versa. They are not designed to be a primary source of heat, as they are designed to work with a furnace.

User questions & answers

Question:	I know it says it has a fan but Mr. Heater removed fans from some models. Is this one of those models
Answer:	The low voltage fan and switch IS NOT on this unit. There is a kit that can be ordered from another party that consist of the entire rear panel. It has the wiring an hardware attached to it with the switch, battery case and external low voltage plug for a transformer power supply. It is as simple as 4 screws to install. Mine was under $40. I could not find this larger heater WITH the fan anywhere. Many say it has the fan in the remarks but is not included. I hope this helped. Jack, Dayton OH.
Question:	Is this safe to use indoors? Like gas wise
Answer:	Many fear that anything burning gas will be like running a generator indoors that will kill you in 10 minutes. I understand such a concern, but this is much more like someone running a gas stove burner used in half the houses, that doesn't kill anyone in 10 minutes while warming water for coffee or such (does it?) It burns clean enough that there isn't the carbon-monoxide like from a generator. I ran the smaller version (Buddy) for 24 hours to do a "power outage drill" with freezing temps out to see what it's like with a CO detector set up, the CO unit never went off. I did go outside a few times like to get the mail and when coming back inside I could smell a bit of the "Burned gas", but it wasn't so bad to need to run back out. So you do want to consider such, but it's not a panic item. The manual does suggest cracking a window for some ventilation, but others say "That's letting your heat out in freezing conditions and stupid!" So it's up to you to perhaps do some experiments and come to your own conclusions. There's always the thoughts on possible gas leaks to check for before any use, so don't be afraid to do that. If using a hose and refillable tank, here's a simple leak check I do. With everything connected and heater off, open the tank valve watching how the hose "jumps" when getting pressurized, then close the tank valve, wait 1-2 minutes, then open it again watching for another "Jump" in the hose. If it does jump again, that means gas leaked out over the 2 minutes, otherwise no jump means it held pressure. It is against fire codes to have a refillable tank inside (anything except 1 pound tanks), so I think that can give you another purpose in having a window cracked, yet I've seen a video on another heater that uses those big tanks with it shown used in a garage (despite the "Outdoor use only" label showing somewhat contradictory info). So lots to consider in using these including the surface it sits on (they warn "May cause floor fading or vinyl damage").
Question:	What size propane can does the heater use
Answer:	It has places for 2 of the small 1 pound tanks like you find in the camping section of stores like Walmart, Target, etc. You can also get a hose like the F273704 by Mr Heater and go to any bigger tank you want (like the 20 pound BBQ ones, or bigger or smaller). On high this will burn the 2 pounds from small tanks in 3 hours, so running it 12 hours in a good shop will burn near half a 20 pound tank in a day. Many like the bigger tanks for both length it runs and propane can go for $3 a gallon in bigger tanks vs $3 a quart in those disposable tanks.
Question:	Can this heater be used inside a camper
Answer:	Sure it can. I live full time in a 40 foot RV and use a Mr. Heater Big Buddy that is hooked to a external 30lb tank. Then my other main heater is a Olympian Wave 8 that is plumbed into my RV's propane line. It produces no C02 when its in use but it does consume oxygen so as a result your ceiling vent should be cracked open a inch or two. For every pound of propane used there is X amount of ounces of water that is released in the form of water vapor. Having a window ajar releases this out of the camper. You can also get a dehumidifier to deal with that. You will instantly know this if you use this with no windows open ... your windows will be covered in condensation. You might think leaving a window open will let the cold in ... quite the opposite. It creates a convection current that aids in the heating of your camper.

User questions & answers

Question:	Where is the gas inlet located
Answer:	If you are facing the front of the heater, the gas connection can be found on the lower right hand side coming from the rear.
Question:	I am concerned about having to use a battery to ignite the pilot light. Is this a problem and are there other types of ignition systems
Answer:	This uses a very small battery for ignition. The life of it is usually not an issue.
Question:	After starting the unit up for the very first time and letting it heat up for 5 or so minutes my fire/smoke detectors went off, is this normal
Answer:	I had a scenario where this heater made a serious billowing smoke show. Kicked the smoke detectors off immediately. Only happened 2- 3 times in a 2 ish year period. It happened with this propane heater too. Don't let this scare you though. Can happen with any infrared heater. It only happened several times over a period of about 2 years. So it probably only happened 1 out of a thousand times where the pilot light was on, but for some reason when it went to light up the burner bricks it malfunctioned and billowed out smoke like you wouldn't believe. Made it hard to get to the heater to turn it off. ALWAYS worked after simply turning it off, and ligting it up again. Maybe another reason why you must have working smoke detectors. Doesn't keep me from buying another one! Overcome your fears. Doesn't mean you won't first feel afraid if smoke suddenly starts pouring out of the kitchen. Lol. NEVER let your fears control you. Everything breaks it's just a matter of time. Keep safety # 1.
Question:	what is the thermostat temperature range in degrees high/low
Answer:	There is no real thermostat in Mr. Heater. It is more of a reostat the controls the time the 5 panels are on and off. At the number 1 setting the panels are on a short time and off a longer time. As you go from 1 up the panels stay on longer and the off time gets shorter. I have not been able to run on the 5 setting as the CO2 sensor turns the heater off after two cycles of setting 2. My external carbon dioxide sensor also goes off after 15 minutes of operation and on setting 2 and after the Mr Heater CO2 sensor turns off the propane. I would not recommend this heater to anyone.
