Venting System Inspection
Blower Assembly Dilution Air Holes
Location of Dilution Air Holes
The water heater’s internal flue must be inspected annually to be certain it is clean by removing the blower assembly and flue baffle.
When reinstalling the flue baffle make certain it is hung securely by its hanger at the top of the flue way.
Reinstall the blower assembly.
Inspect plastic vent pipe. Make certain that all joints are secure and that vent pipe supports are all in place. Check the outdoor vent terminal to see that it is free of obstructions, and that there is no damage nearby caused by condensate.
Inspect dilution air holes. Make certain no blockage exists. Clean any lint, dirt or oil accumulation that may exist.
Test for spillage at the dilution air holes after 5 minutes of burner operation. Place a blown out match or candle close to the dilution are holes. The smoke from the candle or match should be drawn into the dilution air holes. If the smoke is pushed away from the dilution air holes, the blower or vent system may be blocked. Contact qualified service personnel.
