Maintenance; Boiler Maintenance; General Care; Inspection - IBC SL 14-115 G3 Installation And Operating Instructions Manual

CAUTION
The owner is responsible for
general care of the boiler.
Improper maintenance of the
boiler may result in a hazardous
condition.
WARNING
Label all wires prior to
disconnection when servicing
controls. Wiring errors can
cause improper and dangerous
operation.
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.
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.

4.0 MAINTENANCE

4.1 BOILER MAINTENANCE

4.1.1 General Care

• Keep combustible materials and flammable liquids and vapors 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

• Remove any obstructions from the vent terminals (e.g. leaves, dust, other debris).
• 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

• The 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
the trap has been re-filled completely before firing boiler.
• If condensate neutralization is used, check the pH level of condensate discharge.

4.1.5 Burner

• Annually, remove the burner to inspect for fouling (refer to the burner removal and
reassembly instructions, section 3.4.2 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 the burner requires cleaning every year. In alternate years, visually inspect
the burner through the sight glass. Ensure that the flame is stable and is without
excessive fluttering. Normal flame pattern is evenly distributed over the burner surface.
• If the burner is operating improperly, remove and clean or replace. Use a CO
to determine proper combustion. See Table 7 for the correct values.

4.1.6 Heat Exchanger

During annual inspection (with the burner removed), examine the heat exchanger for
signs of contamination and clean if necessary. In areas of poor gas quality, there may be
a buildup of black plaque (typically sulfur). Other fouling agents may consist of: airborne
dust, debris and volatiles.
Refer to Gaining access to the combustion chamber Section 3.4.1 for instructions on
accessing to the combustion chamber and heat exchanger. Note that the safety warning
regarding burner refractory on this page must be observed.
