CAUTION
Equipment Damage Hazard.
Can burn out thermostat or transformer.
Applying a jumper across (or shorting) the valve
coil terminals, even temporarily, can burn out the
thermostat or transformer.
Follow the appliance manufacturer's instructions if
available; otherwise use these instructions as a guide.
IMPORTANT
These gas controls are shipped with protective
seals over the inlet and outlet tappings. Do not
remove the seals until ready to install adapters
or connect the piping.
Converting Gas Control from
Natural Gas to LP Gas (or LP Gas
to Natural Gas)
WARNING
Fire Or Explosion Hazard.
Can cause property damage, severe injury
or death.
1. Always change the main orifices when
converting from natural to LP gas or from LP to
natural gas. Carefully follow appliance
manufacturer's specifications and instructions
to assure proper appliance conversion.
2. Gas controls are factory-set for natural or LP
gas. Do not attempt to use a gas control set for
natural gas on LP gas, or a gas control set for
LP gas on natural gas.
See Table 3 for the correct conversion kit.
Install Bushings To Control
If bushings are being installed on the control, mount them
as follows:
Bushings
1. Remove the seal over the control inlet or outlet.
2. Apply a moderate amount of good quality pipe
compound to the bushing, leaving two end threads
bare. On an LP installation, use a compound that is
resistant to LP gas. Do not use Teflon tape.
3. Insert the bushing in the control and carefully thread
the pipe into the bushing until tight.
Complete the instructions below for installing the piping,
installing the control, and connecting the wiring. Make
sure the leak test you perform on the control after
completing the installation includes leak testing the
bushings.
VR9205Q DIRECT IGNITION COMBINATION 2-STAGE GAS CONTROLS
Location
The gas controls are mounted in the appliance vestibule
on the gas manifold. If this is a replacement application,
mount the gas control in the same location as the old
control.
Locate the combination gas control where it cannot be
affected by steam cleaning, high humidity, or dripping
water, corrosive chemicals, dust or grease accumulation
or excessive heat.
To assure proper operation, follow these guidelines:
• Locate the gas control in a well-ventilated area.
• Mount the gas control high enough above cabinet
bottom to avoid exposure to flooding or splashing
water.
• Assure the ambient temperature does not exceed the
ambient temperature ratings for each component.
• Cover the gas control if appliance is cleaned with
water, steam, or chemicals or to avoid dust and grease
accumulation.
• Avoid locating the gas control where exposure to
corrosive chemical fumes or dripping water are likely.
Install Piping to Control
All piping must comply with local codes and ordinances or
with the National Fuel Gas Code (ANSI Z223.1,
NFPA No. 54), whichever applies. Tubing installation must
comply with approved standards and practices.
1. Use new, properly reamed pipe that is free from
2. Run pipe or tubing to the control. If tubing is used,
