Venting System Inspection
The venting system of a direct vent water
heater 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 9 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
opening and vent outlet on the termination
has 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.

the water heater should be shut off until
qualified service assistance can be
obtained.
CAUTION: For your safety, burner
inspection and cleaning should be
performed only by qualified service
personnel.
For cleaning, a vacuum cleaner can be
used on the burner.
Proper burner pattern.
