• Make visual inspection of main burner and pilot flames
at start of heating season and again in mid-season. Main
burner flame should have well defined inner blue mantel
with lighter blue outer mantel. Check burner throats and
burner orifices for lint or dust obstruction. See Figure 16.
• Pilot flame should envelop ⅜ to ½ inch of tip of ignition/
sensing electrode. See Figure 18.
• To adjust pilot flame, remove pilot adjustment cover
screw and turn inner adjustment screw counterclockwise
to increase or clockwise to decrease pilot
flame. Be sure to replace cover screw after adjustment to
prevent possible gas leakage. See Figure 14, Page 20.
• Check burners and pilot for signs of corrosion, rust or
scale buildup. Area around boiler must be kept clear
and free of combustible materials, gasoline and other
flammable vapors and liquids.
• Free flow of combustion and ventilating air to boiler and
boiler room must not be restricted or blocked.
• Inspect field sourced low water cutoffs annually, or
as recommended by low water cutoff manufacturer.
Flush float type low water cutoffs per manufacturer's
instructions.
• Employ a qualified service agency to make annual
inspection of boiler and heating system. They are
experienced in making the inspections outlined above,
and, in event repairs or corrections are necessary,
trained technicians make the proper changes for safe
operation of the boiler.
