WHEN INSTALLING THIS PRODUCT…
1. Read these instructions carefully. Failure to fol-
low them could damage the product or cause a hazardous
condition.
2. Check the ratings given in the instructions and on the
product to ensure the product is suitable for your application.
3. Ensure installer is a trained, experienced service
technician.
4. After installation is complete, use these instructions to
check out product operation.
WARNING
FIRE OR EXPLOSION HAZARD,
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY, OR DEATH.
Follow these warnings exactly:
1. Disconnect power supply before wiring to pre-
vent electrical shock or equipment damage.
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 installation.
3. Do not bend pilot tubing at gas control or pilot
burner after compression fitting has been tight-
ened, or gas leakage at the connection may result.
4. Always install sediment trap in gas supply line
to prevent contamination of gas control.
5. Do not force the gas control knob. Use only your
hand to push down the reset button or turn the
gas control knob. Never use any tools. If the gas
control knob or reset button will not operate by
hand, the gas control should be replaced by a
qualified service technician. Force or attempted
repair may result in fire or explosion.
CAUTION
Never apply a jumper across or short the valve coil
terminals. This may burn out the heat anticipator in
the thermostat.

CONVERTING 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
an LP gas system or a gas control set for LP
gas on a natural gas system.
2. When making conversion, main pilot burner
orifices must be changed to meet appliance
manufacturer specifications.
VR8200 and VR4200 gas controls can be converted
from one gas to another. To convert from natural gas to LP,
use the 393691 LP Conversion Kit that is included with the
gas control. To convert from LP to natural gas, use the
394588 Natural Gas Conversion Kit (ordered separately).
VR8200C,P and VR4200C,P gas controls cannot be con-
verted.
To convert control from one gas to another:
1. Turn off main gas supply to the appliance.
2. Remove the regulator cap screw and pressure regulator
adjusting screw. See Fig. 2 or 3.
3. Remove the existing spring.
4. Insert the replacement spring with the tapered end
down. See Fig. 4.
5. Install the new plastic pressure regulator adjustment
screw so that the top of the screw is flush (level) with the top
of the regulator. Turn the pressure regulator adjustment
screw clockwise six complete turns. This provides a
preliminary pressure setting of about 10.0 in. wc [2.5 kPa]
