Cr

a Burner model number breakdown is as follows: First digit indentifies burner as– 4 = gas only 5 = oil only 6 = dual-fuel Next 3 digits, 131, identify the burner as part of the integral fan series: Letter (G) designates burner frame size Anything appearing after (G) shows fuel selection– 2 =#2 or #4 oil

b Capacities and flame lengths are with 20% excess air, firing into a cold tight chamber at atmospheric pressure.

c

Fuel rates are based on the following calorific values: 1000 Btu/ft 3 of natural gas

135 000 Btu/gallon of light (#2 or #4) oil 150 000 Btu/gallon of heavy (#5 or #6) oil 145 000 Btu/gallon of crude oil

d

1800 rpm based on 60 hertz operation. With operation on 50 hertz, the speed becomes 1500 rpm (compensated for with large impeller).

 Oil and dual-fuel burners require addition of an accessory package for atomizing medium. Pressure range required at inlet of that package is 75 to 100 psi for air and 50 to 125 psi for steam.  Oil and dual-fuel burners require oil to be delivered to burner hinge at viscosity not to exceed 100 SSU and at the pressure listed above. If a liquid fuel other than a commercial fuel oil is to be used, consult North American for recommendations of pressure and flow requirements.  Gas burners are intended for use with natural gas or propane. Listed pressures are for natural gas only--consult Fives North American Combustion, Inc. for pressures with propane. These pressures are required at inlet of butterfly gas valve when burner is firing at rated capacity into a chamber at neutral pressure. All pressures and flows listed are maximum values and are intended to be used only for system sizing information (not for ratio adjustment).
