J. Visually inspect the baffles for any unusual wear or soot build up. Clean if necessary.
K. Visually inspect the venter assembly for any unusual wear or dirt build up. Vacuum
if necessary.
L. Place a sheet of heavy paper or similar material in the bottom of the combustion
chamber and brush down the flue passageways. The soot and scale will collect on
the paper and is easily removed with the paper.
M. Replace the Flue Collector using the hold down screws and silicone in place with GE
IS 808 silicone or similar. (See figure 15 on page 14.)
N. Repeat steps A-E in reverse order to reassemble the boiler.
O. Start boiler to insure proper operating condition.
1. KEEP the area around the boiler clean and free of combustible materials such as
gasoline, paints, paint thinner and other such flammable vapors and liquids.
2. The free flow of combustion and ventilating air to the boiler and boiler room must
not be restricted or blocked.
3. Some circulators require periodic servicing. These circulators usually have oil
cups or openings at each end of the motor and one for the shaft bearing. Put about
one teaspoon of SAE 20 or 30 non-detergent motor oil in each opening twice per
year. DO NOT OVER OIL. Follow the manufacturer's instructions attached to the
circulator. When oil cups or holes are not provided, bearings are either permanently
lubricated or water lubricated.
3. VISUALLY CHECK THE MAIN BURNERS AND PILOT FLAME AT THE START OF
EACH HEATING SEASON AND AGAIN MIDWAY THROUGH THE SEASON.
A. Check the burner throats and burner orifices for lint and dust obstructions. See
figure 15 on page 14.
B. The main burner flame should have a well defined inner blue mantel with a lighter
blue outer mantel. (See figure 16 above.)
C. The pilot flame should envelop 3/8" (.95 cm) to 1/2" (1.27 cm) of the tip of the
pilot sensing device. (See figure 17 above.)
4. ADJUSTING THE PILOT FLAME:
A. Remove the pilot adjustment cover screw.
B. Turn inner screw (adjustment screw) clockwise
counterclockwise
C. After adjustment, be sure to replace cover screw to prevent possible gas leakage.
D. The main burners and the pilot burner should be checked for signs of corrosion or
scale build up.
E. Clean main burners and pilot burner with a steel bristle brush.
to increase the pilot flame, see figure 10 on page 11.
