1.4 Conversion and Adjustment Instructions
Before converting or adjusting the machine, 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 from one type of gas to another, the main gas orifice (or injector), the
pilot burner orifice (or injector), and the primary air adjustment must be changed according
to the table on page 9. In addition, the spring in the pressure regulator must be changed so
that it can operate at higher pressures.
1.6 Verification for use with Natural Gas
The highest flame setting ("on" position on the manifold gas valves) for each of the pipe
burners can be confirmed by using the volumetric method in conjunction with the main gas
meter. From the "pilot" position, turn the Gas Control Lever clock-wise, towards "on", until
the lever goes no further.
To carry out this verification procedure, it is necessary to obtain the heating value (BTU/ft 3 )
of the local gas from the local gas company.
If the measured gas volume does not correspond to the values in the following table, the
first item which should be checked is the incoming (connected) gas pressure. If the
pressure is correct, it must be verified that the proper size gas orifices are in place.
