Follow these warnings exactly:
1.
Disconnect power supply before installing or
servicing.
2.
To avoid dangerous accumulation of fuel gas,
turn off gas supply at the appliance service
valve before starting installation, and perform
Gas Leak Test after completion of installa-
tion.
3.
Do not bend pilot tubing within 3” of the gas control
or pilot burner after compression fitting has
been tightened, or gas leakage at the connec-
tion may result.

Converting Between Natural Gas
and LP Gas
If needed, convert valve between Natural and LP gas.
WARNING
Fire or Explosion Hazard.
Can cause property damage, severe injury, or
death.
1.
Do not use a gas control set for natural gas on LP
gas or a gas control set for LP gas on natural
gas.
2.
When making the conversion, the main and pilot
burner orifices MUST be changed to meet
the specifications of the appliance manufac-
turer.
Standard or slow-opening gas controls can be converted
from one gas to another. To convert from natural gas to
LP, use the 393691 LP Conversion Kit. To convert from LP
to natural gas, use the 394588 Natural Gas Conversion
Kit. Step-opening gas controls cannot be converted.
To convert the control from one gas to another:
1.
Turn off the main gas supply to the appliance.
2.
Remove the regulator cap screw and pressure reg-
ulator adjusting screw. See Fig. 1.
3.
Remove the existing spring.
4.
Insert the replacement spring with the tapered end
down. See Fig. 2.
5.
Install the new plastic pressure regulator adjust-
ment screw so that the top of the screw is flush
(level) with the top of the regulator. Turn the pres-
sure regulator adjustment screw clockwise
six complete turns. This provides a preliminary
pressure setting of about 10.0 in. wc (2.5 kPA) for
an LP regulator and a 3.5 in. wc (0.9 kPA) for a nat-
ural gas regulator.
6.
Check the regulator setting with a manometer or by
clocking the gas meter after gas control is
installed. See the Startup and Checkout section.
7.
Install the new cap screw.
8.
Mount the conversion label on the control.
Install the control according to the appliance
manufacturer instructions.
