Answer: 
The altitude I have used this Forsaire furnace at 7000 feet in La Verta Colorado. I have two-- they were already installed when I bought the home 22 years ago, and they have performed really well and dependably. I am not aware if they have altitude adapters. They are rated BTU HR 48,750. It is a good thermostat controlled furnace. In all this time have not had a single service call. Model # 465 FXR LPG

Rated 3.6 out of 5 by 7 reviewers.
Rated 1.0 out of 5.0 by damaged product even after reading many reviews on Home Depot about the Williams furnace arriving damaged and beat-up from the factory we ordered this item. It arrived damaged and the furnace appeared to have a lot of abusive handling that didn't show on the cardboard box. That indicates to me that the problem is in the factory and not in the shipping process. I believe that any intelligent quality control person could find and stop the problem easily upon inspection of the process and observing the workers putting the furnace into the packaging. Appears they use wire chokers and a crane/lift to pick up the furnace and put into the boxes and while being lifted are damaged. Probably as easy to remedy as using wide nylon slings instead of wire/rope slings. September 6, 2016
Rated 3.0 out of 5.0 by Dented It's hard to open this at the store. Outside of package looked fine. When we opened it the unit had dents all over it. As if someone dropped it off the truck to move it. We haven't finishing installing and will be seriously bummed if the unit has broken parts inside. We have a highly skilled licensed plumber installing it. He said not the best instructions or access to the piping areas but we are installing in wall which might be why it's harder to reach. Photo is of dent AFTER we tried fixing it. Lucky for us it's the side facing into corner. The vent plates also damaged. Needed to bang those out just to get them on. August 2, 2015
Rated 5.0 out of 5.0 by good product came as advertised the unit was easy to install, all parts were there except for the propane line hook up. Instructions are easy to follow. July 1, 2014
Rated 5.0 out of 5.0 by Extremely fast shipping, exceded expectations! When a furnace goes out in early winter in Northern Ohio it is always a stressful situation. The research/purchase, delivery happened in less than 24 hours. The furnace was a direct replacement for the broken unit and had no installation issues. Five star! December 8, 2015
Rated 5.0 out of 5.0 by seems great but is yet to be seen it,s new i have just got it installed a couple of weeks ago seems to work just fine quite a job to install for a couple of old people but we got it done pretty heavy but runs pretty smooth I hope it continues to do so time will tell I think it is pretty good deal. October 23, 2015
Rated 4.0 out of 5.0 by perfect for my cabin I bought one of these units for my 700 sq ft cabin and it works really well. It was easy to install and pretty much came ready to go out of the box. I like everything about it although it is slightly louder than I imagined. That's probably not fair to say because the cabin is so small. Even when the temp went well below 0 it still had no problems keeping up. I wish they could have been able to make the overall unit a bit smaller but even still it isn't that bad. February 9, 2015
Rated 2.0 out of 5.0 by Furnace that not all dinged up Sorry we are on the third one, every one of them came to us dented or parts not working. Home Depot employees were very very wonderful about helping us to get one not so dented and working. It does throw great heat just sad Williams doesn't have good quality control on there products before being shipped. November 11, 2014
