Answer: 
This is not a direct vent furnace. It requires a vertical B-type double wall vent that does not come with the unit and must be purchased separately.

Answer: 
No. It must be vented from the top, with a vertical run to the building roof, normally through a wall cavity into which the furnace is recessed.

No. Trailers, RV's, Mobile homes, etc. have specific requirements to reduce and prevent release of hazardous gases into living spaces. This unit is not suitable for any installation except where there as a very large source of combustion air.

Answer: 
The lighting procedure involves placing the gas valve into the PILOT position, pressing the valve in to begin the release of gas for the pilot light, then pressing a piezoelectric sparker (similar to what is on some gas BBQ grills and other propane appliances) until the plot flame is lit. Once the pilot is lit for a minute or so the gas valve can be release then twisted to the ON position.

The place where I want to install is on a wall and can not be vented straight up thru the attic and roof. Can I vent it thru the wall, then put in a 90 degree elbow and vent it up with pipes above the roof line?

Answer: 
If you can find and properly install the correctly sized Type-B fittings there should be no reason you cannot route the flue through the wall then vertical after first routing it vertical for a few feet directly above the furnace draft hood.

Answer: 
This furnace must vent vertical for the first 24 inches, after that you are allowed to angle the vent up to 45 degrees, but no more. Going through a wall with two 90 degree elbows would not meet code.

Rated 4.0 out of 5 by 66 reviewers.
Rated 3.0 out of 5.0 by The good,the bad, and the ugly and all the above I bought this heater to replace a very old wall heating unit TEMCO that was leaking gas and carbon monoxide. The installation supposed to be quick and easy, but I still decided to hire a professional HVAC tech. However, it was nightmarish. It was very hard to fit the unit into an existing wall whole so I had extra expenditures on boards, insulation and spacers. The small over-heating sensor was mounted on the side of the unit and techs accidentally damaged it during installation, so needed to be replaced with a new one. Came with a cheap and BROKEN thermostat so I ended up buying a new one and paying extra for installation...thanks to Home Depot Customer Service that gave me partial credit for that. After installation the unit seemed to work fine except the noise. During the heating cycle the unit produces the normal sound( white noise) but after the temperature has been reached you can hear the clicking and nocking sounds from the chamber and the vent. Called the Williams Customer Service and they explained that this is normal-"metal is cooling off and the noise you hear is the trunk lines and chamber cooling down..'. So,since I sleep in that room -I better get used to the noise. April 21, 2015
Rated 5.0 out of 5.0 by Great purchase- warms my heart, my toes and didn't burn up my checkbook balance! My previous wall furnace was already hooked up to a chimney for venting, so it only took a few minutes to undo the previous gas line to pull out the old, and this new one was the exact same measurements and looked to be nearly identical in every way, so reinstall was a snap for my brother. It took him an hour and a half to put this in, and because of newer connections when I got a whole house furnace handling the upstairs of my house a few years ago, they put in the venting at that time so, I did not need any extra parts as some stated they had to get for a complete connection and to get it up and running. That was a priority to check out since so many complained of that issue...so install day went well with that knowledge. Its been in for a month now, and all seems to be working perfectly...and I hope it continues that way. The other it replaced was there for 35 years, and my brother said this one is actually made from better materials in the combustion chamber area. And I love the thermostat instead of having to crawl around on the floor to adjust the temp, just using the wall thermostat was a huge upgrade! December 10, 2014
Rated 5.0 out of 5.0 by Works great!!!! Works great installation wasn't to bad and loved the fact that Home Depot had the PDF of the instructions available online before I purchased February 10, 2016
Rated 5.0 out of 5.0 by monterey furnace 35000 btu furnace fit right into same hole the other one came out of. had to reroute gas pipe. fired right up and is working perfect. the only down fall was should have ordered it in summer when I new furnace was bad it cost me an extra $100 right before winter and back then it was free shipping to house I could only pick up at store for free. February 10, 2016
Rated 5.0 out of 5.0 by Nice unit Replaced a 30 yr old heater in a rental unit with the Williams Monterey wall heater, works great! January 6, 2014
Rated 4.0 out of 5.0 by Good Value for the money We own a seasonal summer cottage in Minnesota. We shut it down for the winter. I shopped around and bought this one to replace the old wall furnace of similar dimensions. To heat the place (800 sq. ft.) on cool autumn days & nights, it does a fine job so far. It has to be alot more energy efficient than the 50 yr old unit, right? How long it holds up remains to be seen (planned obsolescence?) I bought the blower accessory too, which is noisier than I had hoped, and underpowered compared to my last furnace. I place a portable fan nearby to move air more forcefully. The installer said it was not difficult to work with including lp conversion. I also bought a thru the wall fan which I'm very happy with too, and is in the photo (if it uploads). There was a manufacturing dent on the access panel which I was able to easily fix. I had a problem finding attic vent pipe. Home Depot does not offer it. I found Amerivent brand type B vent pipe at another home center via special order. Summary; so far, I'm happy, but longevity remains to be seen. I'll report back in a few years. November 8, 2012
Rated 1.0 out of 5.0 by I need HELP. My new wall furnace worked for about a week. I changed out the thermostat but that did not fix the problem. The pilot light burns all right but when I turn the thermostat on, I get NO fire. The Gas Co. is coming out this Friday to check it out. Then I will go back to the store for help. December 8, 2015
Rated 5.0 out of 5.0 by Great heater for the price Great heater but only comes in a white color. Don't know if it comes in other colors. A tan or earth tone color would be better. The white really stands out on a wood paneling background. December 15, 2015
