VR8215S,T DIRECT IGNITION COMBINATION GAS CONTROLS

69-2253—01
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 manufacturers 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 specifications and instructions to
assure proper appliance conversion.
2. Gas controls are factory-set for natural (and
manufactured) or LP gas. Do not attempt to use
a gas control set for natural (manufactured) gas
on LP gas, or a gas control set for LP gas on
natural (manufactured) gas.
Controls with standard and slow-opening regulators
(model numbers with suffix S or T) can be converted from
one gas to the other with a conversion kit (ordered
separately). See Table 4 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 compound that is
resistant to LP gas.
NOTE: 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. 3.
Install Control
1.
Can be mounted in any direction.
2.
Mount so the gas flow is in the direction of the arrow
on the bottom of the control.
NOTE: Gas valve will leak if installed backwards.
3.
Thread the pipe the amount shown in Table 5 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. 4.
5.
Remove the seals over the control inlet and outlet if
necessary.
6.
Connect the pipe to the control inlet and outlet. Use
a wrench on the square ends of the control.
