If it has not been run for several months it could be dust burning off.

Check manual, get LP conversion part number than order. If no manual look online under the model number and look up.

Yes, click on the following link and it will take you to Master Distributors. They stock DESA/Vanguard parts. Sorry that you'll have to pay for something that was supposed to come standard with the heater.

Be sure you have your Model Number handy when ordering.

Pilot light goes out when you turn it down to just one burner

From what you described, it may be a case of turning the control knob down to far and it's turning the pilot light OFF.

Other causes:
1. Unit needs cleaning and servicing due to a dust and lint build up inside the heater.
2. ODS Pilot Sensor is partially clogged.
3. Low gas pressure.
4. Thermocouple is failing and needs to be replaced.

In case you have misplaced the Owners Manual for this model heater, I have included a link to it. You can download and print the manual for future reference.

In addition, I you want to undertake the cleaning and servicing process, I have also included a link to a "How to Clean the Pilot Assembly" demonstration.

You model heater uses the Copreci Pilot Assembly.

Armed with all this information, you should be able to further troubleshoot and solve the problem.

Hope this helps you. Please let me know. Thanks!

The flame is orange and I noticed it was running high and when we leave it on one burner it wants to shut off. I have dusted and cleaned it and it didn't improve it. Now when we go to light it usually...

Sounds like thermocouple is part of the problem as it relates to lighting the heater. Overtime, they do become pitted or corroded and should be replaced. As far as the orange flame when running on high is concerned, it sounds like the air intake valve on the burner is partially clogged with dust or lint. I realize you said, "I have dusted and cleaned it and it didn't improve it" But, if you didn't take the front of the heater cabinet off and cleaned all if the interior (including the burners, the plaques, the pilot and the interior walls of the cabinet), your cleaning wasn't sufficient. A Shop Vac with a hose, brush attachment and crevice tool works real well to help you accomplish this. Also, a can of compressed air with a straw nozzle (like you clean your computer with) will aid you in cleaning the pilot orifice and the Oxygen Depletion Sensor (ODS). To further assist you, I have included a link to your Owners Manual (in case you have misplaced yours) that you can download and print for future reference.Be sure the heater is cool and the gas has been turned off to the heater, before attempting to clean the heater.

Hope this helps you to solve the problem.

Control knob gets too warm and starts to melt/losen from shaft.

I don't know how old your heater is, but from what you have described, sounds like a run-a-way burner. In other words, the burner has failed and is producing to high a flame height. Thus, overheating the metal cabinet and causing the control knob shaft and knob to become extremely hot.

Although this heater has a stainless steel tube type burner, It is not beyond the possibility that the burner has rusted out somewhere along the burner tube and flames are shooting out in the wrong place(s). This could be especially true, if the heater was not cleaned and serviced on at least an annual basis.

The only way to check this out is by dismantling the heater cabinet, to expose all of the internal workings. It is not difficult to os, just be sure to turn the gas line to heater OFF and let it cool.

Remove the sheet metal screws along the outer 4 sides of the heater and the cabinet's front can be removed. Check the burner and it's gas connections carefully, to find any degradation that may have occurred, as well as any char marks inside the cabinet.

I have provided a link to your heater's Owners Manual, which should be of more help. You can download and print it if your so desire.

Until this problem is solved, it would be in your best interest to stop using the heater all together.

Hope this helps you find the problem and solve it.

The pilot light keeps going out on my wall-mounted Comfort Glow gas heater. Why?

it is usually the thermocouple so you or your service agent who is qualified to repair the heater must check the thermocouple and if its connected to valve properly swap for new if not that its the valve and you swap for new

Smell of gas. no leaks. no smell when just the pilot on. no smell when bricks are lit. just smells between thermastat going on & the ignition of bricks

If possible, ignite on a lower setting then increase rather than igniting on the high setting.
If there is no manual adjustment, I would call a gas engineer to sort out the problem, as you do not want a malfunctioning gas appliance in your home.

Problem with pilot shuting after heater thermostat cycles off

It could be a few things:
1.Not enough fresh air or the unit is too large for the room it is installed.
(Try to open a window)
2. It could be low gas pressure. This can happen it your LP tank is low or something is wrong with the line.
(Call your gas or LP company)
3. ODS Pilot may be clogged.
(Use a vaccum cleaner, pressurized air, or a small, soft bristled brush to clean).

If this does not fix the problem you may need to replace the pilot. You can contact them at 800-446-1446 or on-line at I hope this helps!
