 Beginning of Each Heating Season

• 

Check boiler area is free from combustible materials, 

gasoline, and other flammable vapors and liquids.

• 

Visually inspect combustion air and vent piping for 

proper operation.  Check for and remove any obstruction 

to flow of combustion air or vent gases. Immediately 

repair or replace pipe showing deterioration or leakage. 

Reassemble per instructions in section 6. Ensure proper 

reassembly and resealing of system.

• 

Visually inspect condensate drain line for proper 

operation. Checking for deteriorated or plugged 

condensate drain line. Verify condensate trap drains 

freely. 

• 

Test safety relief valve for proper operation.  Refer to 

valve manufacturer's instructions packaged with relief 

valve.

• 

Examine flue passages in heat exchanger, burner, 

condensate lines, and cleaning (if necessary) by following 

instructions in “Annual Examination and Cleaning of Boiler 

Components” in this section.

• 

Combustion air blower motor furnished with boiler are 

permanently lubricated from factory and require no 

further lubrication. Lubricate field sourced pumps and/or 

motors according to pump and/or motor manufacturer’s 

instruction.

• 

Check following components are operating properly and 
are free of blockages or obstructions: 

• 

system air vent;

• 

check venturi air inlet for blockage and clean as 

required;

• 

verify pressure test port cap and combustion test port 

are in place;

• 

return temperature sensor clip must be securely 

seated on pipe; Check boiler for any sign of leaks.

• 

Check field sourced low water cutoff according to relief 

valve manufacturer instructions.

• 

Check flame signal with user interface. Should be 8

 

micro 

amps at 100% firing rate ( High fire).

• 

Visual inspection of flame through sight glass. Burner 

should be fully illuminated. See

 

figure 11-1.

• 

Check heating system expansion tank.

CAUTION

Label all wires prior to disconnection when servicing 

controls.  Wiring errors can cause improper and 

dangerous operation. 

!

  

NOTICE

Verify proper operation after servicing.

NOTICE

Perform regular service and maintenance by 

qualified service agency at least once every 12 

months to assure safe, trouble free operation and 

maximum efficiency.

FIGURE 11-1 Sight Glass - 050/075/100/150/200 MBH

DANGER

Before servicing, turn off electrical power to boiler 

at service switch. Close manual gas valve to turn 

gas supply OFF to boiler. Failure to comply will 

result in death or serious injury.
