SECTION 4: MAINTENANCE
This boiler has been designed to provide years of trouble
free performance in normal installations. Examination by the
homeowner at the beginning of each heating season, and in
mid-heating season, should assure continued good perfor-
mance. In addition, the boiler should be examined by a quali-
fied service professional at least once every year.
NOTE: Do not draw water from heating system for clean-
ing. Minerals in the water can build up on the heat trans-
fer surfaces and cause overheating and subsequent fail-
ure of the cast iron sections.
NOTE: To reduce the risk of fouling, the low water cut-off
should be blown down at least once a week during heat-
ing season.
BEFORE EACH HEATING SEASON
1. Remove and inspect draft diverter and smoke pipe (con-
necting draft diverter to chimney or vent) for obstructions,
soot accumulation, rust or corrosion. Clean and replace as
necessary. Check tightness of joints; seal all joints where
necessary.
2. Check boiler flue passageways in the boiler sections for
any blockage or soot accumulation. Remove jacket top and
draft diverter. Using a flashlight, examine all flue passage-
ways.
a. If passageways are free of soot and obstructions, replace
draft diverter and seal with furnace cement.
b. If passageways need cleaning, remove flueway baffles
and burners as described in paragraph 3 below. Insert
long-handle bristle flue brush down between section
tubes and upward through sections from combustion
chamber in both diagonal directions to remove carbon
from finned surfaces. Vacuum debris. Replace the draft
diverter and seal with furnace cement.
c. Reinstall jacket top panel.
3. Check and clean burner assembly. Remove burner access
panel. Lift burners up and to rear until burners are disen-
gaged from orifices. Brush top of burners with soft bristle
brush and blow out with air or vacuum.
DANGER:To avoid fire and explosion hazards: Do not
store anything against the boiler or allow dirt or
debris to accumulate in the area immediately sur-
rounding the boiler. Keep boiler area clear and free
from combustible materials, gasoline and other
flammable vapors and liquids. Lint, paper or rags
must not be allowed to accumulate near the burners.
Do not place clothing on boiler casing to dry.
