CHECKING FOR SUFFICIENT COMBUSTION AIR OR VENTING ISSUES

Draft Test

After successfully lighting the water heater, allow the unit to operate for 15 minutes and check the draft hood relief opening for proper draft. Make sure all other appliances in the area are operating and all doors/windows are closed when performing the draft test. Pass a match flame or smoke around the relief opening of the draft hood. A steady flame or smoke drawn into the opening indicates proper draft.

If the flame flutters or is blown out, combustion products are escaping from the relief opening. If this occurs, do not operate the water heater until proper adjustments or repairs are made to the vent pipe system and/or air supply requirements.

External Inspection & Cleaning of the Base-Ring Filter

1.At least annually check the base-ring filter for any dust or debris that may have accumulated on the filter screen. NOTE: If the water heater is located in an area that is subjected to lint and dirt, it may be necessary to check the base-ring filter more frequently.

2.Follow the Lighting Instructions to turn off the water heater and allow it to cool for 10 minutes before attempting to clean the base-ring filter.

3.Use a vacuum cleaner with a hose attachment to remove any dust or debris that may have accumulated on the filter. NOTE: If unable to inspect or clean the base-ring filter, follow the “Cleaning the Combustion Chamber and Flame- arrestor” instructions below.

4.After the base-ring filter has been cleaned, follow the Lighting Instructions to return the water heater to service.

Cleaning the Combustion Chamber and Flame-arrestor

1.Follow procedure outlined in “Removing the Manifold/Burner Assembly” (See page 22).

2.Use a vacuum cleaner/shop vac to remove all loose debris in the combustion chamber. Use compressed air to clear any dust or debris that may have accumulated in the flame-arrestor.
