Visually inspect hot surface ignitor.
To ensure sufficient ventilation and
combustion air supply, proper clearances
must be maintained.
When installed in a closet,
DO NOT
block or obstruct any of the combustion
air inlet openings located around
the perimeter of the water heater. A
minimum of 1” is required between these
combustion air inlet openings and any
obstruction.
DO NOT obstruct or block the Flammable
Vapour Sensor. The sensor does not
require any maintenance or cleaning.
DO NOT expose to cleaning agents.
!
DANGER: Combustible
materials, such as clothing,
cleaning materials, or
flammable liquids, etc.,
must not be placed against
or next to the water heater.
Burner Inspection
Visually inspect the pilot flame and main
burner annually.
Through the sight glass, inspect the pilot
and burner lighting. If any unusual pilot or
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 burner must be performed only
by qualified service personnel, as it
involves the disconnection of gas piping
and leak testing. The burner chamber is
a sealed area. If the burner access door
is removed, the burner access door
gasket must be replaced
.
For cleaning, remove the burner from the
water heater. A vacuum cleaner can be
used on the burner and floor shield inside
the water heater. The burner can also be
cleaned by scrubbing with mild detergent.
Venting System Inspection
The water heater’s internal flue must be
inspected annually to be certain it is clean
by removing the blower assembly and flue
baffle.
When reinstalling the flue baffle make
certain it is hung securely by its hanger at
the top of the flue way.
Reinstall the blower assembly.
Inspect plastic vent pipe. Make certain
that all joints are secure and that vent
pipe supports are all in place. Check the
outdoor vent terminal to see that it is
free of obstructions, and that there is no
damage nearby caused by condensate.
Inspect dilution air holes. Make certain no
blockage exists. Clean any lint, dirt or oil
accumulation that may exist.
Test for spillage at the dilution air holes
after 5 minutes of burner operation. Place
a blown out match or candle close to the
dilution are holes. The smoke from the
candle or match should be drawn into the
dilution air holes. If the smoke is pushed
away from the dilution air holes, the
blower or vent system may be blocked.
Contact qualified service personnel.
