Annual Service/Maintenance 

Preventative care can extend the lifespan of your heater and reduce the likelihood of problems. Unmaintained units can result in inefficient heating and extra cost. 

What type of maintenance is needed?

• Heater components should be cleaned and dusted regularly to remove dirt, dust and debris. 

• Heater should be inspected for loose or damaged parts such as screws, bolts or brackets. 

•  Inspect & clean the heating elements, coils or burner.  Thoroughly examine the heating elements, coil and other components for damage or corrosion. 

• Verify that the thermostat is functioning correctly and test for accuracy.  Calibrate as necessary. 

• Verify that the circuit breaker or gas supply is functioning correctly. 

• Inspect the vent and exhaust system.

• Replace air filters when necessary. 

• For gas wall heaters, inspect the pilot light. Ensure it’s consistently lit and burning blue. A flickering or yellow flame may indicate a problem.

• Test the safety features, such as the thermocouple, to ensure they are functioning correctly. Address any issues identified with the thermocouple or flame sensor. 

• Check for air or gas flow obstructions.

• Verify there are no gas or carbon monoxide leaks. 

• Listen for any unusual noises. Rattling, clicking or banging should not be ignored.  These sounds can indicate a problem with the blower motor or fan, issues with the gas valve or igniter, debris in the heater unit or loose/damaged component.

• Ensure your unit has proper ventilation and clearances around the heater.
