EXAMPLE:
Btu heating input = Btu/cu ft X cu ft/hr
Heating value of gas = 1070 Btu/cu ft
Time for 1 revolution of 2 cu ft dial = 72 sec
Gas rate = 100 X 1070 = 107,000 Btuh

(8.) Measured gas input should not exceed gas input on

unit rating plate.

(9.) Proceed to item c to adjust manifold pressure.

c. Adjust gas input.

(1.) Remove regulator adjustment seal cap. (See Fig.

11.)

(2.) Turn adjusting screw counterclockwise to decrease

input. Turn screw clockwise to increase input. DO
NOT set manifold pressure less than 3.2-in. wc or
more than 3.8-in. wc for natural gas. Make any
major adjustments by changing main burner ori-
fices.

(3.) When correct input is obtained, replace regulator

seal cap. Main burner flame should be clear blue,
almost transparent. (See Fig. 12.)

d. High altitude—In the United States gas input on rating

plate is for altitudes up to 2000 ft. Ratings for altitudes
over 2000 ft must be 4 percent less for each 1000 ft
above sea level. To obtain the adjusted altitude rating,
adjust the manifold pressure (see item c) and replace the
main burner orifices as needed. Refer to National Fuel
Gas Code Appendix F, Table F-4 for proper orifice
sizing at high altitudes.

e. Canadian installations only—The Canadian ratings are

approved for altitudes up to 2000 ft for natural and
propane gases. High-altitude ratings are from 2000 ft to
4500 ft above sea level. See Table 8 for nominal burner
orifice size. High-altitude rating includes a 10 percent
derate as required by Canadian standards.
