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 3.4.1 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 7 for correct values..

  

4.1

WARNING

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.
