WATER HEATER SERVICE TIP:

TO KEEP YOUR WATER HEATER IN PEAK PERFORMANCE

Like other appliances, your water heater will need occasional servicing to maintain peak performance.

Sufficient air flow is crucial to the proper operation of your water heater. This publication addresses one

possible cause of restricted air flow, and the procedure for its prevention and correction. Signs of restricted

air flow are yellow flames, pilot outage, sooting, or unstable flame. Before starting, consult the sections of

your owner’s manual dealing with condensation, air requirements, gas supply, venting, and cleaning the air

intake screen. Also, make sure that your water heater is properly sized for your home. An undersized water

heater may result in condensation which can drip onto the flame causing a pilot outage.

Your water heater is built to the current industry safety standard and meets all FVIR (flammable vapor

ignition resistant) requirements. This assures that any flammable vapors drawn into the combustion

chamber and ignited can not ignite remaining flammable vapors on the exterior of the water heater causing

a fire or explosion. This design includes a flame arrestor and one or two air intake screen(s). These

screen(s) prevent larger particles of dust or lint from entering the water heater, thus restricting air flow and

causing improper combustion. The owner’s manual asks you to visually check and clean the screen(s) as

necessary.

Smaller particles may pass through these screens and lodge in the flame arrestor.

The following paragraphs address the cleaning of the flame arrestor and the combustion chamber. This

procedure should be done in two phases: 1) under the water heater and 2) the combustion chamber.

Required tools are commonly found in most homes, and additionally are available in most home stores or

super centers.
