Gas Conversion and Adjustment Instructions
Before converting or adjusting the machine to another type of gas, it is imperative that the
manual gas cock be turned to the "off" position. The electrical power to the machines should
also be turned off. When converting the gas generators for use from one type of gas use to
another, the gas orifice (or injector) must be changed according to the table on page 8. In
addition, the spring in the pressure regulator supplied with the unit must be changed so that it
can operate at other gas pressures. Springs for the regulator can be ordered from Hickory
Industries.

Verification for use with Natural Gas
The flame setting for the gas generator can be confirmed by using
the volumetric method in conjunction with the main gas meter. The burner has an
independent solenoid gas valve. The valve is controlled by an independent Gaslite
spark ignition module. The amount of gas flowing through the valve can not be adjusted
manually; there is only an "on" or "off" position.
To carry out this verification procedure, it is necessary to obtain the heating value (BTU/ft
of the local gas from the local gas company.
A variation in the heating value of the local gas from that on the table (1.6) will result in
a variation of the power output of the unit!
If the measured gas volume does not correspond to the values in the following table (1.6), the
items which should be checked are:
A.
The incoming (connected) gas pressure while the burners and all other appliances
in the location are operational.
B.
If the gas pressure is correct, it must be verified that the proper size gas orifices are in
place (see page 8).
