If your furnace isn't producing enough heat, there are a few potential causes. First, the furnace might be undersized for the space. Second, the thermostat may be set too low. Try raising the temperature setting. Finally, there could be incorrect supply pressure, which needs to be checked.
Why does my COZY Wall Furnaces have a yellow burner flame?
A yellow burner flame may be caused by clogged burner ports. Remove the main burner and check for obstructions in the throat, ports, and orifices. Clean them, but do not enlarge the ports or orifices. Another cause may be an obstruction around the vent cap. Ensure the area around the vent cap is clear and that the vent system is sealed.
What to do if my COZY Wall Furnaces pilot and main burner go out during normal operation?
If the pilot and main burner go out during normal operation, it could be due to a few reasons. Check for a weak powerpile or thermocouple; test the millivoltage and replace if it's low. The input might be too high, so check the input rate. The cover around the pilot lighter hole might not be airtight; tighten the wing nuts securing the cover and sight glass, and check/replace the gasket if needed. Also, vent tubes might not be properly installed or sealed; follow the instructions to check both exhaust and air intake tubes and the vent cap, ensuring all gaskets are in place and properly sealed, and using only the supplied tubes and vent cap without alterations. Finally, incorrect vent tubes could be the issue; replace them with the correct ones.
How to fix delayed ignition in COZY CDV335C?
Delayed ignition can occur for several reasons. The pilot flame might be too small, so adjust it. Burner ports may be clogged at the pilot, requiring cleaning (do not enlarge them). Low gas pressure could be the cause; check the gas supply pressure. If the pilot decreases in size when the main burners come on, the supply piping is too small, and you should consult your local gas company or a competent installer.
Why is the flame too large in my COZY Wall Furnaces?
A flame that is too large can be attributed to several factors: a defective operator section of the valve, in which case you should replace the valve; a burner orifice that is too large, so check with your local gas company for the proper orifice size and replace it if necessary; or if the unit is installed above 2,000 ft., refer to the burner orifice section on Page 13.
