VR9105V, F AND VR9205V, F DIRECT IGNITION GAS CONTROL WITH INTEGRATED 1:1 REGULATOR
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.
VR9105V, F and VR9205V, F cannot be converted
between LP or Natural gas. To convert, see
appliance manufacturer for recommendations.
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.
2. Apply a moderate amount of good quality pipe
compound to the bushing, leaving two end threads
bare. On an LP installation, use 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, connecting the wiring. Make sure the
leak test you perform on the control after completing the
installation includes leak testing the bushings.
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 gas control in a well-ventilated area.
• Mount 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 gas control if appliance is cleaned with water,
steam, or chemicals or to avoid dust and grease
accumulation.
• Avoid locating 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
chips. If tubing is used, make sure the ends are
square, deburred and clean. All tubing bends must
be smooth and without deformation.
2. Run pipe or tubing to the control. If tubing is used,
obtain a tube-to-pipe coupling to connect the tubing
to the control.

3. Install a sediment trap in the supply line to the
control. See Fig. 4.
Install Control
1. Mount with the coils 90 degrees from the vertical
upright position. See Fig. 3.
2. Mount so the gas flow is in the direction of the arrow
on the bottom of the control.
3. Thread the pipe the amount shown in Table 3 for
insertion into control or adapters. Do not thread
pipe too far. Valve distortion or malfunction can
result if the pipe is inserted too deeply.
4. Apply a moderate amount of good quality pipe
compound (do not use Teflon tape) only to the pipe,
leaving two end threads bare. On LP installations,
use a compound resistant to LP gas. See Fig. 5.
5. Remove the seals over the control inlet and outlet
before installing pipe.
6. Connect the pipe to the control inlet. Use a socket
on the hex end of the control. See Fig. 6.
Do not use the wrench on a Venturi Manifold.
