4. Remove the combination flue collector and draft hood from the boiler castings by
loosening the nuts on the hold down bolts located on each side of the collector. See figure
11 on page 19.
5. Place a sheet of heavy paper or similar material over the bottom of the base and
brush down the flue passageways. The soot and scale will collect on the paper and is easily
removed with the paper.
With the paper still in place in the base, clean the top of the boiler castings of the boiler
putty or silicone used to seal between the castings and flue collector. Make certain that chips
are not lodged in the flue passageways.
When the cleaning process is complete, restore the boiler components to their original
position. Use boiler putty or IS-808 GE silicone, available from a Utica Boilers distributor,
to seal around the flue collector and boiler castings.
A visual check of the main burner and pilot flames should be made at the start of the
heating season and again in mid-season. The main burner flame should have a well defined
inner blue mantel with a lighter blue outer mantel. Check the burner throats and burner
orifices for lint or dust obstruction. See figures 12 and 13 below.
The pilot flame should envelope 3/8 to 1/2 inch of the tip of the pilot thermocouple,
ignition/sensing electrode or mercury sensor. See figure 14 on page 21 To adjust the pilot
flame, remove the pilot adjustment cover screw (figures 8 and 9 on pages 16 and 17), and
turn the 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.
The burners and pilot should be checked for signs of corrosion, rust or scale
buildup. The area around the boiler must be kept clear and free of combustible
materials, gasoline and other flammable vapors and liquids.
The free flow of combustion and ventilating air to the boiler and boiler room must
not be restricted or blocked.
It is recommended that a qualified service agency be employed to make an annual
inspection of the boiler and heating system. They are experienced in making the inspections
outlined above, and, in the event repairs or corrections are necessary, trained technicians
can make the proper changes for safe operation of the boiler.
