14 - GENERAL  MAINTENANCE AND CARE INSTRUCTIONS

• 

Before seasonal start-up, have a certified service agency 

check boiler for soot and scale in flues, clean burners 

and check gas input rate to maintain high operating 

efficiency.

• Verify proper operation after servicing.
• 

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 entire piping 

system and, if any leaks appear, have them repaired.

• Circulators need to be checked and maintained. 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 a mirror, check vent for obstruction and verify 

vent is in good working order.

• 

Boiler flue gas passageways may be inspected by a light 

and mirror. 

◊ 

Remove burner door.

 See 

Figure 13-1 page 29

◊ Place trouble lamp in flue collector through draft relief 

opening or flue inspection cover. 

◊ With mirror positioned above burners, flue gas 

passageways can be checked for soot or scale

Follow this procedure to clean flue gas passageways:

1. 

Remove burner tray from heat exchanger by 

disconnecting the gas supply, by removing two (2) 

nuts. Pull out the assembly.  see Figure 14-1 page 31.

2. 

Remove top jacket panel.

3. 

Remove flue inspection cover.

4. 

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. 

5. 

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 (available from distributor) to seal around flue 

collector, and inspection cover if required.

WARNING

Label all wires prior to disconnection when servicing 

controls. Wiring errors could cause improper and 

dangerous operation.
