Condensate Trap Inspection
On a regular basis, inspect the condensate
trap to ensure there is enough water in the
trap and the condensate is draining properly.
Ensure that condensate is disposed of per
local codes and regulations.
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 and
vent outlet on the termination has not been
blocked or contain debris.
Burner Inspection
Visually inspect the main burners annually.
Through the front sight glass, inspect the
burner flame. Blue flames should be seen
when the main burner is firing. See the figure
on the left for location of sight glass.
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, burner
inspection and cleaning should be
performed only by qualified service
personnel.
For cleaning, a vacuum cleaner can be used
on the burner.
If the water heater is to remain idle for an
extended period of time, the power and water
to the appliance should be turned off.
The water heater and piping should be
drained if they might be subjected to freezing
temperatures.
After a long shut-down period, the water
heater’s operation and controls should be
checked by qualified service personnel.
