VR8304 INTERMITTENT PILOT COMBINATION GAS CONTROL

69-0625—03 2

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 property

damage, severe injury, or death.

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

the 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, 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 turn the gas control knob. Never

use 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

Never apply a jumper across or short the valve

coil terminals. This may burn out the heat

anticipator in the thermostat or damage the

electronic intermittent pilot (IP) module.

IMPORTANT

These gas controls are shipped with protective

seals over inlet and outlet tappings. Do not

remove the seals until you are ready to connect

piping.

Follow the appliance manufacturer’s instruc-

tions if available; otherwise, use the instructions

provided below.

Converting Between Natural and

LP Gas

WARNING

Fire or explosion hazard. Can cause property

damage, severe injury, or death.

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.

To convert a gas control from natural gas to LP gas or

from LP gas to natural gas, contact your Honeywell

representative.

Standard- or slow-opening gas controls are converted

from one gas to another with a conversion kit (order

separately). Order Part Number 393691 to convert from

natural to LP gas. Order Part Number 394588 to convert

from LP to natural gas. Step-opening gas controls cannot

be converted.

Install Adapters to Gas Control

Install adapters to the gas control as follows:

Flanges

1. Choose the appropriate flange for your application.

2. Remove the seal over the gas control inlet or outlet.

3. Ensure the O-ring is fitted in the groove of the

flange. If the O-ring is not attached or is missing, do

not use the flange.

4. With the O-ring facing the gas control, align the

screw holes on the gas control with the holes in the

flange. Insert and tighten the screws provided with

the flange. See Fig. 1. Tighten the screws to 25 in.

pounds of torque to provide a gas-tight seal.

Fig. 1. Install flange to gas control.

Bushings

1. Remove the seal over the gas control inlet or outlet.

2. Apply moderate amount of good quality pipe com-

pound to the bushing, leaving two end threads bare.

On LP installation, use a compound resistant to LP

gas. Do not use Teflon tape.

3. Insert the bushing into the gas control and thread

the pipe carefully into the bushing until tight.

Using Adapters to Solve Swing

Radius Problems

In some field service applications, it is difficult or

impossible to thread the gas control onto the gas supply

pipe because of space limitations. This problem can be

resolved in many instances by using an adapter. The

adapter is installed on the end of the supply pipe in place

of the gas control, following the same precautions and

instructions that are used for installing the gas control.

After the adapter is installed, the gas control is attached to

the adapter as outlined above. Note that using an adapter

increases the overall length of the gas control.
