Venting System Inspection
The venting system should be inspected
annually to ensure all of the vent sections
are secure and air-tight.
It is recommended that qualified service
personnel familiar with Category III
venting inspect the venting system.
Check vent connection joint sections with
a solution of soapy water to assure air-
tightness while the unit is operating.
Bubbles around a joint connection
indicates a seal leak. Refer to page 12 for
vent sealing instructions.
DO NOT operate the unit if vent system
shows signs of leaking exhaust.
Check to make sure that the Air Intake and
the vent terminal have not been blocked or
contain debris.
Burner Inspection
Visually inspect the main burners
annually.
Through the sight glass, inspect the burner
flame with the main burner off and inspect
the main burner while firing.
If any unusual burner operation is noted,
the water heater should be shut off until
qualified service assistance can be
obtained.
CAUTION: For your safety, cleaning of
the main burner should be performed only
by qualified service personnel.
For cleaning, a vacuum cleaner can be
used on the burner.
