INSTALLATION

When Installing this Product…

1.

Read these instructions carefully. Failure to follow 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 serious injury, death or property 

damage.

Follow these warnings exactly.

1. Disconnect power supply before wiring to prevent 

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 tightened. 
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 turn the gas control knob. Never use any 

tools. If the gas control knob 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

Equipment Damage Hazard.

Improper wiring can damage equipment.

Never apply a jumper across or short the valve coil 

terminals. This may burn out the heat anticipator in the 

thermostat.

IMPORTANT: 

These gas controls are shipped with protective seals 
over inlet and outlet tappings. Do not remove seals 

until ready to connect piping.

Follow the appliance manufacturer’s instructions if available; 

otherwise, use the instructions provided below.

Convert Between Natural and LP Gas

WARNING

Fire or Explosion Hazard.
Can cause serious injury, death or property 

damage. 

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 

natural gas system.

2. When making conversion, main pilot burner orifices 

MUST be changed to meet appliance 

manufacture’s specifications.

Standard- or slow-opening gas controls are converted from 
one gas to another with a conversion kit. To convert from 

natural gas to LP, use the 393691 LP Conversion Kit that is 

included with the V8200 gas control. To convert from LP to 
natural gas, use the 394588 Natural Gas Conversion Kit 

(order separately). Step-opening gas controls can not be 

converted.

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.

3.

Remove the existing spring.

4.

Insert the replacement spring with tapered end down. 

See Fig. 3.

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

eleven complete 

turns. This provides a preliminary pressure setting 

of about 10.0 in. wc (2.5 kPa) for LP regulator and 
3.5 in. wc (0.9 kPa) for natural gas regulator.

6.

Check the regulator setting either with a manometer or 

by clocking the gas meter. Refer to Startup and 
Checkout.

7.

Install the new cap screw.

8.

Mount conversion label on control.

9.

Install control and appliance according to appliance 

manufacturer’s instructions.
