Heating Surface Cleaning
WARNING: Failure to disconnect all electrical
power to the boiler before cleaning it could
result in a fi re or severe personal burn injuries!
WARNING: Never attempt to operate the boiler
with the cleanout cover plate(s) removed! Failure
to comply with this warning can result in a fi re
which could cause extensive property damage,
severe personal injury or death!
Disconnect all electrical power to the boiler before
proceeding. Remove the cleanout cover access panel
from the left side of the boiler. Remove the cleanout
cover plate(s) taking care not to damage the insulation
between the cover plate(s) and the boiler. Use a wire
brush to thoroughly clean the fi reside surfaces. For the
best results, start brushing from the top and work down
toward the combustion chamber. Disconnect the fl ue
pipe and inspect it and the smoke hood for soot build up.
Clean them thoroughly before reconnecting them. Open
the cleanout door on the right side of the burner mounting
plate. Carefully vacuum any soot or scale from the bottom
of the combustion chamber. Do not contact the ceramic
blanket in the bottom of the combustion chamber or it
will be damaged.
IMPORTANT - If the ceramic blanket is damaged
it must be replaced! Failure to replace a
damaged ceramic blanket can result in the
failure of the cast iron sections!
8 SERIES BOILER INSTALLATION AND OPERATING INSTRUCTIONS
Inspect the cleanout door gasket and insulation and
replace them if damaged. Close the cleanout door and
tighten it into place. Inspect the cleanout cover insulation
and replace it if damaged. It is important to maintain
the integrity of the gas seal by careful installation of
the cleanout cover plate. Be sure there is no opening
to allow gases to escape. Install the cleanout cover
plate(s) and tighten into place. Install the cleanout cover
access panel. Restore electrical power to the boiler and
ensure that it operates properly.
Chimney and Smoke Pipe
Be sure that the chimney and smoke pipe do not
become obstructed by birds nests, squirrels, soot,
chimney liner deterioration, or other debris. Keep
chimney cleanout doors closed and sealed tight around
the frames. Be sure the smoke pipe is inserted only at
the nearest chimney liner surface and seal around the
pipe with insulating cement.
WARNING: Be sure that no combustible
materials are stored close to the boiler or
smoke pipe. Fires can cause personal injury and
property damage.
