Venting System And Blower - John Wood POWER VENTED GAS FIRED WATER HEATER Installation And Operating Instructions Manual

Venting System and Blower

WARNING
Keep the area around the heater clear and
unobstructed.
Inspect the venting system periodically to make certain that
the vent passageways, vent terminal and blower assembly
are free and unobstructed. Ensure that any condensate is
draining freely. Clean as necessary.
•
Inspect the vent piping, elbows and connections for signs
of stress cracking or deterioration. Make certain the vent-
ing is free to move and that all pipe hangers and isolation
supports are properly positioned and securely attached.
Any broken components or installation problems should
be corrected by a qualified service technician.
•
Particles, especially lint, can clog the vent blower wheel.
This can be problematic, especially where condensation
is present, as particles may adhere to the venting sur-
faces. These conditions can result in nuisance failures.
In areas that have a high level of airborne particulate
(e.g. lint, sawdust, process smoke, laundry areas, etc.)
inspection and cleaning may need to be done more fre-
quently. The blower wheel and venting must be cleaned
as required to ensure proper performance. This must be
done by a qualified service technician.
•
Inspect the flue collector area for signs of corrosion (see
Figure 41). This can be an indication of contaminated air,
a wet environment, poor burner set up, or high levels of
condensation occurring at the flue collector. Determine
and correct any poor operating conditions.
