CLEANING
Pilot Light and Burner Inspection
Once a year, visually inspect the pilot light, then the
main burner while in operation. Through the sight glass,
confirm that both flames are blue and exhibit the pattern
shown in the illustration below. If a different flame pattern
or color is noted or soot has built up on the burner,
turn off the water heater and call a qualified service
technician.
CAUTION
The pilot light and main burner are in
a sealed chamber. Only a qualified
service technician
should access this chamber. Refer to Sealed Burner
Assembly Warning, page 4.
Once a year, visually inspect the water pipes and
connections, repairing any leaks or damaged fittings.
If you smell gas, refer to Lighting and Shutdown, page 7.
Check the water heater’s venting system:
1. Visually inspect the vent hood and vent pipes to
ensure they are firmly attached.
2. Visually check for soot or any physical deterioration of
the venting system. If corrosion or soot are detected,
call the local gas utility to address the problem and
replace the venting system before placing the water
heater back in operation. (Not covered under the
product warranty.)
