Clean or replace filters as necessary

High-Efficiency Filter Considerations

Is a high-efficiency filter installed?

Measure the static pressure drop across the high-efficiency filter

Is the static pressure drop within acceptable limits?

Record any issues with system capacity or performance due to filter pressure drop

Check the following potential issues

If the unit locks out again, inspect the unit for blockages.

Ensure all tools and materials are removed from the site

Dispose of any waste materials properly

Preliminary and Seasonal Checks

Inspect electrical wiring for loose connections and tighten as required.

Is the voltage within the range listed on the nameplate?

Inspect condition of condensate traps and drain assembly.

Disassemble and clean condensate traps and drain assembly seasonally.

Ensure furnace has been operating for at least 5 minutes

Shut off all other gas appliances connected to the meter

Record time in seconds for two revolutions of gas through the meter

Divide the recorded time by two to get the average time per revolution

Is the average time per revolution matching the time in Table 16?

Does the manifold pressure match Table 18?

Turn off electrical and gas power supplies to furnace

Remove upper and lower furnace access panels

Disconnect the wires from the gas valve

Remove the burner box cover (if equipped)
