Can I mount this unit under a “through the wall” mounted airconditioning unit as long as vent clearance is at least 30 inches?

Asked by: RFK
Your Air-Conditioner recirculates air from the inside, hence there should not be a problem with fumes. If the window air conditioner has a vent mode of brings in a percentage of outdoor air, then there might be a concern. The best thing to do is to consult a licensed contractor and check your local codes.

30,000 BTU/Hr Direct-Vent Furnace Natural Gas Heater with Wall or Cabinet-Mounted Thermostat is rated 4.3 out of 5 by 165.
Rated 2 out of 5 by from I purchased and installed this unit for a new 1,000 square foot home located in an area that rout... I purchased and installed this unit for a new 1,000 square foot home located in an area that routinely drops below zero degrees from December - March. After about one month the pilot assembly went out on this unit (pilot and thermocouple are one unit) and cost me $68 to replace. Home Depot does not carry this part in their store and so it had to be ordered and it took one week to arrive. About 13 months later the same thing happened - pilot assembly went out. This time I decided to call Williams and talk to one of their service reps and after waiting on hold for 35 minutes I got transferred to another department (waited about another 30 minutes) and they told me that there was nothing that they could do because the parts were no longer under warranty. The unit does work good when it works and will keep my small, well insulated house warm, but it is not reliable. The thermostat that comes with this unit has a very large heat range, meaning that if I set it to 70 degrees, it will shut off at 70 degrees, but will not come on again until the temperature drops down to 63 degrees! The thermostat does not have a heat anticipator and so I purchased a separate thermostat that regulates the heat much better. I would not buy another Williams furnace nor would I recommend one to a friend!

Rated 2 out of 5 by from Very disappointed Purchased in 2013, 4 years and 4 repairs. Now the starter/generator broke, meaning the pilot won't stay on. Parts are expensive and shipping crazy prices. So far I've replaced parts myself. Can't imagine have a plumber come over every time the unit fails. PS: blower option waste of money. Noisy and notbpowerful.

Rated 5 out of 5 by from Very Nice Heater, Excellent Value I bought this heater to heat my back porch. The area I needed to heat is about 15X10, no heat run and many drafts. The heater does an excellent job of heating the area. The packaging was not the best but I escaped with no damaged parts. Installation was a little challenging but that is probably because I am not a heating and cooling person. All in all I would recommend this heater to anyone who wants to heat a good sized space that a space heater just will not keep up with. I added a programmable thermostat to knock the heat down at night and during the day when we are not around. The price is fair for what this heater is capable of...

Very quiet and puts out lots of good heat for our cold Nebraska winter. There was a little problem with installation. Heater would run thru one cycle and stop. Grandson had to call for some assistance. Had trouble keeping the pilot light lit. He had to make a small change and it has worked perfect ever since. This is to my (82 years old) knowledge. There may have been more to it than I understand.

Rated 1 out of 5 by from Bad heat exchanger Bought 30000 btu direct vent worked ok for 2 seasons this fall started it up and it would bang real loud when it shut off and started cooling .called williams they were real nice sent me a new part when I got it it was the wrong size finally got the right part cost 175 to get it fixed that heat exchanger is so thin it was cracked all the way across front and back need to spend more money and buy a better furnace

Rated 5 out of 5 by from I had it installed and had previously had ventless gas... I had it installed and had previously had ventless gas wall heaters, this surpassed any heat they put out. The heat feels even, more like a central heat system, where the ventless gas wall heaters felt hot in places, cold in other rooms. It has a thermostat that keeps the temperature right on target. I love it! and would spend the money all over again!

Rated 3 out of 5 by from Works well but expensive gas costs I used this heater as a back-up for my wood stove in my 520 square foot house. Does a good job heating, but even when only used as back-up heat, I spent a small fortune on gas. Not the most efficient way to heat, but good if you’re looking for a way to heat a small space that is off the grid. I’m switching to a mini split heat pump.

We've had negative temperatures too. I bought blower as well. It's a bit noicy when it comes on but seems to settle down. I was nervous to purchase because if some of the reviews but so far so good!
