Always replace covers on burner controls and boxes as the
electrical contacts. Perform maintenance of controls, gas
valves, and other components in accordance with the furnace
module instruction manual.
Monthly
Check cabinet air filters and replace if dirty. After heavy
snowfall verify that combustion air intakes are not blocked by
snow. Periodically check during periods of snow accumulation
as drifting may also lead to combustion air intake blockage.
Twice Yearly
1. Combustion Air: Check combustion inducer fan for dirt
buildup and lint. Check combustion air intake louvers and
flue box/vent for accumulation of dirt and debris.
2. Cleaning: Inspect and clean flue tubes and combustion
chamber. Keep burner vestibule clean. Dirt and debris
can result in poor combustion and lower efficiency.
Yearly
1. Debris: Check vent terminal screens for blockages and
accumulation.
2. Heater and the Venting System: Shall be inspected
once a year by a qualified service agency.
