ally, at the beginning of the heating season, only
by a qualified service technician. In addition, the
maintenance and care of the boiler designated in
Table 12, page 29 and explained on the following
pages must be performed to assure maximum
boiler efficiency and reliability. Failure to service
and maintain the boiler and system could result in
equipment failure.
Electrical shock hazard — Turn off power to the
boiler before any service operation on the boiler
except as noted otherwise in this manual. Failure
to turn off electrical power could result in electrical
shock, causing severe personal injury or death.
The boiler contains ceramic fiber and fiberglass
materials. Use care when handling these materials
per instructions on page 33 of this manual. Failure

Piping
1. Check the boiler interior piping and all system piping for signs
of leaks. Repair any leaks before proceeding.
Do not use petroleum-based cleaning or sealing
compounds in boiler system. Severe damage to
boiler will occur, resulting in substantial property
damage.
Eliminate all system or boiler leaks. Continual
fresh makeup water will reduce boiler life. Minerals
can build up in sections, reducing heat transfer,
overheating cast iron, and causing section failure.
Leaking water may also cause severe property
damage.
Boiler heating surfaces
The boiler contains ceramic fiber and fiberglass
materials. Use care when handling these materials
per instructions on page 33 of this manual. Failure
to comply could result in severe personal injury.
1. Disconnect the vent pipe at the boiler draft diverter and re-
move draft diverter after turning off power to the boiler.
2. Use a bright light to inspect the boiler flue collector and heat-
ing surfaces.
3. If the vent pipe or boiler interior surfaces show evidence of
soot, follow "Cleaning boiler heating surfaces", page 30. Re-
move the flue collector and clean the boiler if necessary after
closer inspection of boiler heating surfaces.
4. If there is evidence of rusty scale deposits on boiler surfaces,
check the water piping and control system to make sure the
boiler return water temperature is properly maintained (per
this manual).
5. Re
connect vent and draft diverter. Replace all boiler com
before returning to service.
6. Check inside and around boiler for evidence of any leaks from
the boiler. If found, locate source of leaks and repair.
Burners and base
1. After turning off power to the boiler, remove the jacket door
and base access panel.
2. Inspect burners and all other components in the boiler base.
3. If burners must be cleaned, raise rear of each burner to release
from support slot, slide forward and remove. Then brush and
vacuum the burners thoroughly, making sure all ports are free
of debris. Carefully replace all burners, making sure burner
with pilot bracket is replaced in its original position and all
burners are upright (ports up).
4. Inspect the base insulation.
sides of the base and attachment clips are still in place.
If insulation is damaged or displaced, do not oper-
ate the boiler. Replace or reposition insulation as
necessary. Failure to replace damaged insulation
can result in a fire hazard, causing severe personal
injury, death or substantial property damage.
