VR8304 INTERMITTENT PILOT COMBINATION GAS CONTROL

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.

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.

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.

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.

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.
