Question about Desa International Blower Glow Warm Wall Heater

Glo warm wall heater 3 tiles, center tile burns with a big flame

Model 3b-fb, the center burner, the main one, burns with a large yellow flame instead of making the tiles glow red like the other 2 tiles (right and left). I have tried blowing the unit out with a can of "computer air" but it didn't do any good. The other 2 tiles burn fine, (I think) the tiles turn a bright red color and give off alot of heat while the center one just throws a big flame that looks like it could start a fire.

Thanks in advance for any help

SOURCE: I have model # FA-3A.


To correct the problem the whple heater will need to be taken apart and eveything blown out with compressed air....
Dust and dirt gets into the heater and messes with the gas/air mixture and then does not burn right...

The heater needs to be taken apart and clean throughly piece by piece...

Then it will work again...

Glo warm model FA3 burner one and two flame is too high #3 is fine

The higher flame on those 2 burners may be by rusted out. Of course this depends on how old the heater is and how well it has been annually maintained. Unfortunately, DESA International is no longer in business, but some parts are still available. You just have to search the internet for them.

How do you remove wall tiles

Follow following steps -

1.Decide where to remove the grout
2. Scrape the grout away with a utility knife
3.Try a rotary grinder instead.
4.Remove grout until the spacer lugs are visible.
5.Chisel tiles away from the wall.
6.Break the tile if necessary.

If the tiles are grouted, you will have to clear the grout away first. There are inexpensive tools designed specifically for grout removal. After removing the grout, use a small pry bar or a similar tool to pry the tiles away from the wall. Most likely, though, if the tiles were installed onto drywall, the drywall will be damaged during removal. Fortunately, drywall is relatively easy to replace. Once the drywall surface is ready, new tiles can be attached with tile adhesive or mastic. Regrout and seal the tile around the new tiles. *If the new tiles are natural stone they will be very porous and will need to be sealed and dry BEFORE installation.

How and where do I replace a thermocouple on a warm glo wall furnace? Help

There should be a thermocouple in front of the burners that has a copper colored wire that runs from the gas valve to the thermocouple. It is located in the pilot flame as it is a pilot proving switch that tells the gas valve the pilot is lit and its okay to open the gas valve to the main burner.

Strange flame on versa raypak

Part of your fire tile (white like) has fallen into your pilot area and is messing with the gas/air mix. Cleaning it out should clear the pilot and have it return to a nice blue flame. If you can get a look inside the unit from a mirror to be sure the area of tile damage is minimal you should be ok. Of course to be on the same side you may want to call in a heater tech to tear it down and be sure the fire box is still sound.
