clean burners.
Venting system should also be inspected at start of each
heating season. Vent pipe from boiler should be checked for
signs of deterioration or sagging joints. Repair if necessary.
Following procedure should be followed to clean and check
flue gas passageways:
Turn off gas to boiler at manual gas valve. 1.
Remove jacket front panel. See figure 2. 2.
Disconnect vent pipe from vent adapter. 3.
Disconnect air inlet pipe from coupling. See figure 5. 4.
Remove air box covers. See figure 5. 5.
Remove burners from combustion chamber by raising 6.
burners up from manifold orifices and pulling toward
front of boiler. See figure 3.
Remove top panel. See figure 2 7. .
Remove flue collector and venter assembly from boiler 8.
castings by removing hold-down screws located on

GENERAL INSTRUCTIONS
V• isual check of main burner and pilot flames should be
made at start of the heating season and again in mid-
season.
M• ain burner flame should have well defined inner blue
mantel with lighter blue outer mantel. If flame does
not appear this way, check burner throats and burner
orifices for lint or dust obstructions. See figure 6.
P• ilot flame should envelop 3/8 to 1/2 inch of tip of
ignition electrode. To adjust pilot flame, remove
pilot adjustment cover screw on gas valve and
turn inner screw clockwise to decrease or
counterclockwise to increase pilot flame.
Replace cover screw after adjustment to prevent
possible gas leakage. (See figures 1, 7 & 8 below.)
Check b• urners and pilot for signs of corrosion, rust or
scale buildup. Clean with nylon bristle brush.
Keep• area around boiler clear and free of combustible
materials, gasoline and other flammable vapors and
liquids.
F• ree flow of combustion and ventilating air to boiler and
boiler room must not be restricted or blocked.
In event flow of combustion products through flueways• or boiler venting system becomes blocked, pressure
switch or ignition system will shut off main burner gas.
If this condition occurs, do not attempt to place boiler in
operation. Contact qualified service agency.
Annual inspection of boiler and heating system• should be done by qualified service agency. They are
experienced in making inspection outlined above and
in event repairs or corrections are necessary, they can
