User questions & answers

Question:	Is the unit really 35' wide
Answer:	Yup.
Question:	Does this unit work in a mobile home located in California
Answer:	You really would need to check with your local code enforcement officer. Even within California, codes would vary from one municipality to another.
Question:	Will these heaters start on a battery backup
Answer:	As long as your battery back up had an inverter built in to convert to AC and met the power requirements, I’m sure that would be fine. Keep in mind that the fan would have a substantial draw on electric supply
Question:	What accessories are available for a vent extension
Answer:	I found two types of vent extensions available. The straight one that extends through the wall is available for different thicknesses of walls. No additional or add on straight extension was available. The other is a pair of tubes, one for exhaust and one for intake, that essentially moves the wall vent to another location. This extension kit might be available in two different lengths--can't recall for sure on that. The installation manual that comes with the unit is also available online and has some very important information on vent and extension location requirements. Also may need local codes.

User questions & answers

Question:	can you use 5/8 propane pipe or do you have to use 1/2 inch? I have a bunch of 5/8 inch and wanted to use it
Answer:	I used 1/2" soft copper tubing from the propane tank to where it entered the building. From that point we used standard steel black pipe-probably 1/2"pipe. I don't know what 5/8 propane pipe is. Do you mean 5/8" dia. copper tubing? As far as I know pipe sizes come in these designations:1/8",1/4", 1/2" 3/4",1', etc. The numbers refer to the inside dimension of the pipe-(the opening,) not the outside dia.I do not know of a 5/8" pipe. It's best if you don't try and improvise. Follow the mfrs. instructions. Your home is worth more than something you have a "bunch of" already. If you are talking 5/8"dia. copper tubing I don't think that would be a problem but like a previous responder said: 1/2" dia.copper tubing is pretty much a standard
Question:	Is the hook up kit (hose) shown in frequently bought together necessary
Answer:	The unit came with the required shutoff valve and I just had to go to Home Depot and pick up the gas line with the length I needed for my hook up. It was pretty inexpensive getting the hose there.
Question:	What is the btu rating of the fc824p heater
Answer:	output on low 6000 btu high 16000 btu
Question:	We have been researching the rinnai fc824p are there sea level specifications we need to be concerned about we are at 4000 ft
Answer:	I use two of these units, one in my pump house and one in a portion of my barn that has water. I'm at 7,000 feet and they work great. The one thing I had to do is to add a UPS to give the units constant power for when the power goes out.

User questions & answers

Question:	What do you do if your wall is only1&1/2 inches thick? Can the pipe be cut down or is there some extension block for sale that needs to be added
Answer:	You will need a lineset, the vent piping, a pad, a disconnect, a whip, and whatever is needed to attach it to your ductwork.
Question:	Does this have a blower to blow the heat out
Answer:	no it does not
Question:	Will the ashley work well at 9,000 feet

The NATIONAL AVERAGE for 1600sq/ft is: 48,000 - 96,000 BTUs of heat and 2.5 - 3 ton for cooling.. We would recommend speaking with your local installer to ensure the purchase of proper equipment for your application. There are too many factors to consider for an exact online estimate
Question:	Will this work hooked up to a 20 pound or 70 pound propane tank
Answer:	No, the downflow model number of the furnace is GCSS960803BN. Here is the link to a downflow system https://www.amazon.com/dp/B00WZ7CD88.

User questions & answers

Question:	Can this unit be installed through a cut out in the celing so it points down towards the floor while having the majority of the unit in the attic
Answer:	Highly unlikely. The louvers on the front that direct air flow have maybe 45 degrees of downward angle. This just seems like a bad idea
Question:	does it smell when running
Answer:	not after initial burn period .Very quiet compared to my last heater ,does not smell .
Question:	Can it run on a propane tank for a gas grill
Answer:	This heater can run on a gas grill propane tank. Make sure the propane conversation kit has been installed and then you'll need to use a grill hose that has the regulator on it. Then you'll have to change the fitting after the regulator.
Question:	One description says heats 700 sq ft another says 1250. Which is it
Answer:	It heats my 900 sq. ft garage nicely.
