If the burner does not light after the ODS/pilot is lit, the burner orifice may be clogged; in this case you should clean the burner or replace the burner orifice. It is also possible that the inlet gas pressure is too low, so you should contact your local gas company.
Why does my Comfort Glow SBN20 produce unwanted odors?
Your Comfort Glow Gas Heater might be producing unwanted odors because it's burning vapors from paint, hair spray, glues, or other similar products. Ventilate the room and stop using these products while the heater is running. Alternatively, if you are using propane/LP gas, the fuel supply may be low, so refill the supply tank. Finally, there could be a gas leak, so locate and correct all leaks.
What to do if my Comfort Glow SBN20 Gas Heater has a delayed ignition of burner?
If your Comfort Glow Gas Heater experiences a delayed ignition of the burner, it could be due to low manifold pressure, in which case you should contact your local gas company. Another possible cause is a clogged burner orifice. You can resolve this by cleaning the burner or replacing the burner orifice.
How to fix yellow flame during burner combustion in Comfort Glow SBN20?
If you notice a yellow flame during burner combustion in your Comfort Glow Gas Heater, it indicates that the burner is not getting enough air. Inspect the burner for any dirt or debris, and if found, clean the burner.
What to do if Comfort Glow SBN20 Gas Heater burner backfires during combustion?
If the burner is backfiring during combustion, the burner orifice may be clogged or damaged, or the burner itself may be damaged. You can try cleaning the burner, or replacing the burner orifice or the burner. Also, the gas regulator might be defective, requiring replacement.
What to do if Comfort Glow Gas Heater ignitor button is pressed, there is spark at ODS/pilot but no ignition?
If there is a spark at the ODS/pilot but no ignition when the ignitor button is pressed, ensure the gas supply is turned on and the equipment shutoff valve is open. Check that the control knob is in the PILOT position and pressed in. If there is air in the gas lines, continue holding down the control knob and repeat the igniting operation until the air is removed. For propane/LP gas models, check for a depleted gas supply and contact your local gas company if needed. The ODS/pilot may be clogged, requiring cleaning or replacement. Finally, the gas regulator setting may be incorrect, necessitating replacement of the gas regulator.
Why Comfort Glow Gas Heater ignitor button is pressed, there is no spark at ODS/pilot?
If there is no spark at the ODS/pilot when the ignitor button is pressed, the ignitor electrode may be positioned wrong or broken, in which case you should replace the pilot assembly. Also, make sure the ignitor electrode is connected to the ignitor cable, reconnect if needed. The ignitor cable could be pinched, wet, or broken, so free it if pinched, keep it dry, or replace it. The ignitor itself might be bad, requiring replacement. For electronic ignition models, ensure the battery is installed correctly, is not low, or install a new alkaline battery.
What to do if Comfort Glow SBN20 Gas Heater ODS/pilot lights but flame goes out when control knob is released?
If the ODS/pilot lights, but the flame goes out when you release the control knob, make sure the control knob is fully pressed in and held for at least 30 seconds after lighting. The safety interlock system may have been triggered, so wait one minute for it to reset before repeating the ignition. Ensure the equipment shutoff valve is fully open. Check if the thermocouple connection is loose at the control valve and hand tighten it until snug, plus an additional 1/4 turn. It's also possible that the pilot flame isn't touching the thermocouple due to low gas pressure or a dirty/clogged ODS/pilot. In the first case, contact your local gas company, and in the second, clean or replace the ODS/pilot assembly. The thermocouple or control valve might also be damaged, requiring replacement of the p...
This document describes the Comfort Glow Blue Flame Gas Heater, an unvented (vent-free) gas-fired heater designed for residential use. It is suitable for installation in aftermarket, permanently located, manufactured (mobile) homes, provided local codes do not prohibit such installations. The heater operates on either natural gas or propane/LP gas, as indicated on its rating plate, and is not convertible for use with other gas types.
The Comfort Glow Blue Flame Gas Heater provides supplemental heating by burning gas to produce a blue flame, which radiates heat into the room. As an unvented heater, it draws air (oxygen) from the room for combustion and releases combustion products directly into the living space. Therefore, adequate combustion and ventilation air must be provided in the installation area.
A key safety feature of this heater is the Oxygen Depletion Sensing (ODS) safety shutoff system. This system monitors the oxygen level in the room and will automatically shut off the heater if there is not enough fresh air available for proper combustion. This is a required feature for vent-free room heaters.
The heater incorporates an ignition system, which can be either a piezo ignitor or an electronic ignitor, to light the fuel supply. Thermostat models are equipped with a thermostatic heat control that includes a sensing bulb and a control valve. This system adjusts the gas flow to the burner, increasing or decreasing the flame height to maintain the desired room temperature, thereby enhancing comfort and potentially reducing gas consumption. If the room temperature exceeds the set point, the burner will shut off and cycle back on when the temperature drops.
Before operating the heater, it is crucial to read the owner's manual carefully and completely to ensure safe assembly, operation, and service. Improper use can lead to serious injury or death from burns, fire, explosion, electrical shock, and carbon monoxide poisoning.
The thermostat senses room temperature and adjusts gas flow to the burner, modulating flame height. The burner may shut off if the room exceeds the set temperature and will cycle back on when the temperature drops. The control knob can be set to any heat level between HI and LO.
The heater can be mounted to a wall or optionally to the floor.
Regular inspection and cleaning are essential for safe and efficient operation.
The manual provides a comprehensive troubleshooting guide for common issues such as no spark at the ODS/pilot, spark but no ignition, pilot lighting but flame going out, burner not lighting, delayed ignition, burner backfiring, yellow flame, smoke/odor, whistling noise, white powder residue, clicking/ticking noise, unwanted odors, heater shutting off (ODS operates), gas odor when control knob is OFF, gas odor during combustion, and moisture/condensation on windows. Each problem is linked to possible causes and recommended remedies, emphasizing the importance of professional service for complex issues.
