HSG SERIES POWER GAS CONVERION BURNER ORIFICE CHART
Figure 11: Orifice Selection Guide
NOTE:
For 50 cycle application de-rate input by 15%
NOTE: The Btu/hr input values in Figure 11 show the approximate hourly input of the burner for the various orifice
sizes. To determine the actual input of the burner by using the gas meter, follow these steps:
1) Turn off all other gas appliances.
2) The hand on the dial with the lowest cubic feet value (fastest revolving dial) should be clocked for one complete
revolution.
3) Divide 3,600 by the time in seconds for one complete revolution and multiply by the dial value (1, 2, or 5 cubic feet
depending on size of meter.)
4) Multiply this by the heating value of the gas to obtain the input to the burner in Btu per hour.
EXAMPLE: Time in seconds for one complete revolution of dial is 72. 3,600 divided by 72 is 50, 2 cubic foot was timed
therefore 50 x 2 is 100. Multiply 100 by heating value of gas which is 1,075 for natural gas; and this will give you an
input of 107,500 Btu/hr (31.51 kW). Use a heating value of 2500 for LP gas.
Running Pressure Required:
Natural or LP 5.5
” w.c. (1400 Pa) Minimum, 14” w.c. (3500 Pa) Maximum.
De-rate input for altitude over 2000 ft. (609.6 m) by 4% each 1000 ft. (304.8 m) above sea level.
IMPORTANT:
MANIFOLD PRESSURE ADJUSTMENTS CAN ONLY BE MADE WITH THE BURNER
RUNNING AND THE GAS ON.

GAS LEAK HAZARD
Liquefied petroleum gas is heavier than air. All connections should be checked for
leaks using a soapy solution applied to gas connections. Leaking gas will settle in
low lying areas such as basements and trenches. This can lead to asphyxiation and
explosion.
Valve is rated for 0.5 PSI or 14 inch w.c. Over pressurizing valve
may cause damage to the valve.
