BOILER MAINTENANCE
4.1.1 General Care
•
Keep combustible materials and flammable liquids and vapours away from the boiler.
•
Keep vent terminals clear of obstructions (snow, dirt, etc.).
4.1.2 Inspection
Inspection of the boiler is to be performed annually by a qualified service
technician.
4.1.3 Venting
•
Check vent terminals for and remove any obstructions (e.g. leaves, dust,
other debris).
•
Check, and clean or replace intake air filters or screens as required.
•
Check for holes or leaks in venting. Replace venting as needed.
•
Examine for any signs of moisture caused by sweating intake air pipes;
insulate as required.
•
Ensure proper resealing or reinstallation of venting on each servicing.
4.1.4 Condensate Traps
•
Condensate trap must be examined every two months to see if cleaning is
necessary
(refer to trap cleaning instructions, section 1.5.3 of this manual).
Ensure that trap has been re-filled completely before firing boiler.
•
If condensate neutralization is used, check pH level of condensate discharge.
4.1.5 Burner
•
Annually, remove burner to inspect for extent of fouling (refer to burner
removal and reassembly instructions, section 3.5.1 of this manual). Blow
clear using compressed air. Evaluate the magnitude of clearing required, and
establish a reasonable burner inspection schedule. Some boiler / locations
may call for annual service, others showing clean burners will only need
attention every 2 – 5 years. Consider adding air filtration if burner requires
cleaning every year. In alternate years, visually inspect burner through sight
glass. Ensure flame is stable and without excessive fluttering. Normal flame
pattern is evenly distributed over the burner surface.
•
If burner is operating improperly, remove and clean or replace. Use a CO
2
analyzer to determine proper combustion. See Table 11 for correct values.

CAUTION
Label all wires prior to
disconnection when servicing
controls. Wiring errors
can cause improper and
dangerous operation.
CAUTION
The owner is responsible for
general care of the boiler.
Improper maintenance of
the boiler may result in a
hazardous condition.
WARNING
Whenever the burner is
removed for inspection or
boiler servicing, the sealing
gaskets must be examined
and replaced if damaged.
Upon re-assembly, an
approved leak test solution
must be applied around the
burner flange sealing area to
ensure there is no leakage of
combustible gas/air premix.
WARNING
Fill trap with water before
boiler is first fired to prevent
exhaust fumes from entering
room. Never operate the
boiler unless the trap is filled
with water.
Failure to comply will result in
severe personal injury or death.
CAUTION
Periodic inspection of
Low Water Cut-Off Device
including flushing of float
types is required, if installed
as an accessory to the boiler.
