Wall heaters are generally used as an inexpensive way to heat a room. Many of these heaters can be recessed into the wall and offer up to 4,800 watts of heat. For the most part, they cost about a couple hundred dollars. No matter which brand or model you select, however, you are likely to run into some questions. Save yourself some money by troubleshooting the problems on your own.
Flame
If your wall heater's flame is too large, the operator section of your valve may be defective. If this is the case, replace the entire valve. You may also have burner orifices that are too large. Your owner's manual will have installation instructions. You can also contact your local gas company for the correct orifice size. If your flame is yellow, you may have clogged burner parts. You should remove the burners and look for obstructions.
Ignition
If your heater will not ignite, make sure the main gas isn't turned off. Also ensure that the thermostat is set high enough to call for the heat. Check the wiring diagram in your owner's manual for correct wiring. Replace any defective valves, and check the power supply. You should also make sure the pressure switch is not defective.
Heat
If your furnace doesn't seem to be giving off enough heat, it may not be large enough for the particular room. You may need a larger heater. The gas company can help you calculate the heat loss compared to your furnace output. If this is not your problem, perhaps your temperature is set too low. If the heater is giving off too much heat, try lowering the heat dial. Your gas control valve may also be stuck in the open position. If this is the case, you'll want to replace it.
