Is the heat source in the main control panel functional?

Is the heat source adequate for current conditions?

Check the control compartment every two weeks to confirm that the heat source is functional and is adequate for current conditions;

Check combustion inducer fan for dirt buildup and lint

Check combustion air intake louvers and flue box/vent for accumulation of dirt and debris

Inspect and clean flue tubes and combustion chamber

Keep burner vestibule clean. Dirt and debris can result in poor combustion and lower efficiency
