4. CHECK GAS INPUT RATE TO BOILER

USA boilers built for installation at altitudes greater than 2,000 feet above sea level have been specially orificed to reduce gas input rate 4 percent per 1,000 feet above sea level per the National Fuel Gas Code, NFPA 54/ANSI Z223.1, Section 8.1.2 and Appendix F. Canadian boilers' orifice sizing is indicated on the rating label. High altitude boiler models are identifiable by the fourth digit after the dash in the model number. 2: 0-2000', 4 or 5: above 2000'.

A. Input Rate and Maximum Inlet Pressure shown on Rating Label must not be exceeded. Inlet pressure must not be lower than minimum inlet pressure shown on Rating Label.

B. All Rate checks and all adjustments are to be made while boiler is firing - all other appliances connected to the same meter as the boiler must be off.

C. With boiler off, water Manometer or water column gauge should be connected to a shut-off cock installed in the 1/8" outlet pressure tap in the gas valve (See Figure 19). By installing gas cock upstream of manometer, gas pressure can be introduced gradually - without shut-off cock, surge of pressure when boiler is turned on, could blow liquid out of manometer. Replace plug in gas valve when rate check is finished.

D. LP Gas Input:

Adjust Regulator on Gas Valve so that manifold pressure is 10 inches water column. Turning Regula- tor Adjusting Screw Clockwise increases pressure. Counterclockwise rotation decreases pressure.

E. Natural Gas Input

1.Appx. Input - Adjust regulator on Gas Valve so that manifold pressure is three and a half (3½) inches water column (three inches water column for high altitude with 1" main burners). Turning Regulator Adjusting Screw Clockwise increases pressure, Counterclockwise rotation decreases pressure. If more accurate check on input is necessary see (2) below.

For minor input changes readjust Regulator Gas Valve to increase or decrease manifold pressure to obtain corresponding increase or decrease in gas input. If it is necessary to increase manifold pressure more than 0.3" of water to obtain rated input, remove orifices and drill one size larger. Reinstall and recheck input rate.

2.Additional Check on Input - Since input is a function of heating value, specific gravity, and volume of gas flow contact your utility for the first two items in order to utilize the formula below. The gas meter should then be clocked for three (3) minutes with stop watch and substituting the appropriate values in the formula below, determine what the gas flow should be in this 3 minute period to give the input shown on the Rating Label:

5. MAIN BURNER FLAMES should have a clearly defined inner cone (see Figure 22 or 23) with no yellow tipping. Orange-yellow streaks caused by dust should not be confused with true yellow tipping.

The main burners in this boiler will not operate cleanly or efficiently if they are contaminated with dirt and/or construction dust. Burners should be cleaned and the combustion chamber vacuumed following instruc- tions in Section III - Service.

6. CHECK PILOT BURNER FLAME.

A. Continuous Ignition (Standing Pilot)

Models 202 and 202X with 1" diameter burners. See Figure 24.

Models 202 and 202X with 40mm (1-9/16") diameter burners. See Figure 25.

Natural gas Models 203 through 206 and 207 with 1" diameter burners. See Figure 25.

The pilot produces a single flame. The flame should be steady, medium hard blue enveloping 3/8 to a 1/2 inch of thermocouple.
