Thermostat actuates on call for heat, completing circuit 

to control. Completed circuit to control will first activate 

circulator. Control will first monitor water temperature 

with circulator running to determine if thermostat can be 

satisfed without firing burner; if not it will activate damper 

which closes end switch inside damper. Action completes 

circuit to ignition system and ignition takes place.

In event boiler water temperature exceeds high limit 

setting on boiler mounted high limit control, power is 

interrupted between control system and ignition system. 

Power remains off until boiler water temperature drops 

below high limit setting. Circulator continues to operate 

under this condition until thermostat is satisfied. 

In event flow of combustion products through boiler venting 

system becomes blocked, blocked vent safety switch shuts 

main burner gas off. Similarly, if boiler flue-way becomes 

blocked, flame rollout safety switch shuts main burner 

gas off. See Figure 15

.

 

If either of these conditions occur, 

do not attempt to place boiler back into operation. 

Contact certified service agency

Before seasonal start-up, have certified service agency 

check boiler for soot and scale in flues, clean burners and 

check gas input rate to maintain high operating efficiency.

WARNING

Label all wires prior to disconnection when servicing 

controls. Wiring errors could cause improper and 

dangerous operation.

!

  

Verify proper operation after service.

Service agency will verify system is filled with water to 

minimum pressure and open air vents, if used, to expel any 

air accumulated in the system. Check piping system and, if 

leaks are found, have them repaired immediately.

Check and maintain circulators. Refer to circulator 

manufacturer's instructions.

Inspect venting system at the start of each heating 

season. Check vent pipe from boiler to chimney for signs of 

deterioration by rust or sagging joints. Repair if necessary. 

Remove vent pipe at base of chimney or flue and using 

mirror, check vent for obstruction and verify vent is in good 

working order.

Inspect boiler flue gas passageways by a light and mirror. 

Remove burner door. Place trouble lamp in flue collector 

through draft relief opening. With mirror positioned above 

burners, flue gas passageways can be checked for soot or 

scale. See Figure 15.

Follow the following procedure to clean flue gas 

passageways:

1. 

Remove burners from combustion chamber by raising 

burners up from manifold orifices and pulling toward 

front of boiler. See Figure 17, Page 22.

2. 

Disconnect vent pipe from draft hood.

3. 

Remove top jacket panel.

4. 

Remove combination flue collector and draft hood from 

boiler castings by loosening nuts on hold down bolts 

located on each side of collector. See Figure 15.

5. 

Place sheet of heavy paper or similar material over 

bottom of base and brush down flue passageways. Soot 

and scale will collect on paper and is easily removed 

with the paper. 

6. 

With paper still in place in base, clean top of boiler 

castings of boiler putty or silicone used to seal between 

castings and flue collector. Verify chips are not lodged 

in flue passageways.

When cleaning process is complete, restore boiler 

components to their original position. Use IS-808 GE 

silicone to seal around flue collector and boiler castings.
