Questions & Answers

how much clearance is required for the vent?

how much clearance is required for the vent?
Asked by: imagine
This unit is designed to sit tight against the wall. However, it unit could be mounted off the wall some small distance as long and you remember that it is designed to vent through a wall no thicker than 9". Every inch it is mounted away for the wall in one less inch available to the vent to extend through the wall. It is always best to install these things according to manufacturers instructions--against the wall. Additionally, the authority inspecting your installation is probably going to insist it be installed according to manufacturers instructions.

The pdf instructions have zero information on the thermostat for some reason? Does the thermostat have a timer built in for the unit turning itself off and on automatically at specific times?
Asked by: RemRem
No timer, but it does have a wired external thermostat that you can mount on the side of the unit or on a wall.

Can this be installed in a basement?

Can this be installed in a basement?
Asked by: Joe
This unit can only be installed on an exterior wall that is adjacent to the out-of-doors. This unit is vented directly out the back of the unit to the out of doors and away from living space. Typical basement wall does not meet this criteria.

How noisy is it?

Is it too noisy to have in a bedroom (former garage turned into a guest bedroom)
Asked by: curious
I would consider this unit very quiet. There is some minor metal expansion and contraction ticking sound but you are not going to need to raise the TV volume to cover it.

14,000 BTU/Hr Direct-Vent Furnace Natural Gas Heater with Wall or Cabinet-Mounted Thermostat is rated 4.1 out of 5 by 122.
Rated 1 out of 5 by from I have an apartment building and have purchased over 15... I have an apartment building and have purchased over 15 of these units. Normally, these units work great. The latest one has some issue igniting and the unit won't stay lit. We have replaced the thermostat and tried various things on our end to fix the unit. Williams warranty doesn't answer

IMPORTANT...With typical house gasline pressure, you will need a REGULATOR that outputs 5 - 7 wc. The Maxitrol RV43L works. (Designed for restaurant appliance operation.)

This product was exactly what I needed, in the dimensions and BTU's I needed it in, which is why I bought it. It was fairly easy to install, but the wall was open at that time, comes with it's own thermostat, and does a great job heating a well insulated 28x15, or 420 square foot add on to the back of my garage. It also had everything needed to vent it out the exterior wall it's mounted on, which is at least 9 inches thick. That being said, it was very expensive and there were furnaces like this one that were twice the BTU's and only about 1/3rd physically bigger, for a few hundred dollars cheaper. That is why I do not give this 4 stars. It is not a good value at all for what you get. But when you got to fit in a tight spot, you pay the extra.

The ad states NO ELECTRICITY REQUIRED but the unit arrived with a low voltage two wire thermostat, 20' of #18AWG two conductor cable, and no clear instructions on how to wire the unit. Where do you tie the 24Vac to? nothing..... The LP gas conversion kit also has very unclear instructions.

Great system , Unit does not require electric unless you install the optional fan, This unit is an absolute must for smaller confined spaces / rooms propane heaters need to be vented as this one is , Im using this unit in my 25' Rv that I use as my hunting cabin sleeping quarters and haven't had any issues in 3 years ! my only complaint would be that when the unit is cooling down the unit makes a little noise from the metal expansion and contraction ,no big deal

Pilot went out at random intervals, sometimes difficult to re-light, but we managed to relight it, and installer could not find a reproducible problem. 2 year later, pilot will never stay lit, no matter how long we manually hold gas line open. HVAC tech says the pilot assembly needs replacement because there is a crack in the pilot tube - when you light it, the flame doesn't come out at the tip, but at the base of the pilot, so the thermopile never heats up and pilot won't stay on. Not one HVAC supply place in town carries the pilot assembly I need, so I'm ordering the $65 part online. I suspect this part was malfunctioning from day 1, but Williams will not admit that they owe us a new part. This is not a high quality heater -- for $600 I expect something with a pilot assembly that works for more than a month.

So far it works real well,although it hasn't gotten real cold yet, but I'm sure it will do the trick. It started up right away, once I figured the correct knob position for the plot light to start. I must have been misreading the instructions and was turning the knob back too far from the off position....should be about half way.
