CHECKING AND ADJUSTING THE GAS IGNITION COMPONENTS The gas input to the boiler can be adjusted by removing the protective cap on the

pressure regulator, see figure 16 on page 19 , and turning screw clockwise t o

increase input and counterclockwise to decrease input. Natural gas manifold pressure should be set at approximately 3.5 inches water column. Propane gas manifold pressure should be set at approximately 10 inches water column. Manifold pressure is taken at the pressure tap on the outlet side of the gas valve, see figures 11 and 12 on pages 12 and 13. Burner orifices should be changed if the final manifold pressure varies more than plus or minus 0.3 inch water column from the specified pressure.

To check for proper flow of natural gas to boiler divide the input rate on the rating plate by heating value of the gas as obtained from the local gas company. This will determine the number of cubic feet of gas required per hour. With all other gas appliances off, determine

the flow of gas through the meter for two minutes and multiply by 30 to get the hourly rate. Make minor adjustments to the gas input as described above.

Primary air adjustment is not necessary, therefore air shutters are not furnished as standard equipment. Air shutters can be furnished on request when required by local codes or conditions.

A visual check of the main burners and pilot flames should be made at the start of the heating season and again at mid-season.

The main burner flame should have a well defined inner blue mantel with a lighter blue outer mantel. If the flame does not appear this way, check the burner throats and burner orifices for lint or dust obstruction. See figure 17 above.

The pilot flame should envelop 3/8 to 1/2 inch of the tip of the pilot sensor. See figure

18 on page 20. To adjust the pilot flame, remove the pilot adjustment screw and turn the

inner adjustment screw clockwise to decrease or counterclockwise t o increase pilot flame. See figures 11 and 12 on pages 12 & 13. 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 build-up. The area around the boiler should be kept clear and free of combustible materials, gasoline and other flammable vapors and liquids.
