INSTALLATION

When Installing this Product...

Read these instructions carefully. Failure to

follow them could damage the product or cause

a hazardous condition.

Check the ratings given in the instructions and on

the product to make sure the product is suitable for

your application.

technician.

After installation is complete, check out product

operation as provided in these instructions.

WARNING

Oxygen Depletion Hazard.

Can cause injury or death due

to asphyxiation.

Use only vented gas valve models on vented

appliances. Use only unvented gas valve models

on unvented appliances.

WARNING

Fire or Explosion Hazard.

Can cause property damage,

severe injury or death.

Follow these instructions exactly:

Turn off gas supply at the appliance service

valve before starting installation, and perform

a Gas Leak Test after the installation is

complete.

Always install the sediment trap in the gas

supply line to prevent contamination of the

gas valve.

Do not force the gas valve control knob.

Use only your hand to turn the control knob.

If the knob does not operate by hand, the

valve should be replaced by a qualified

service technician.

Do you have a question about the Honeywell RV8310D and is the answer not in the manual?

The Honeywell RV8310D,E is a Millivolt Receiver/Modulating Gas Valve designed for use in vented fireplace and space heating applications. It operates on power supplied by thermopile generators and is compatible with the RT8220A Transmitter.

Function Description

The RV8310D,E gas valve controls the flow of gas to the main burner and pilot. It features a modulating function, allowing for variable flame output, and includes a receiver for remote control via a compatible transmitter. The valve is designed to work in a self-generating power system, utilizing the millivolt output from two Q313 thermopile generators.

Usage Features

Installation:
- Requires careful reading of instructions to prevent damage or hazardous conditions.
- Installation must be performed by a trained, experienced service technician.
- A sediment trap must always be installed in the gas supply line to prevent contamination.
- The valve can be mounted 0 to 90 degrees in any direction, including vertically, from the upright position of the gas control knob.
- Gas flow direction must align with the arrow on the side of the valve.
- Pipe compound (not Teflon tape) should be applied to pipe only, leaving two end threads bare. For LP installations, use LP-resistant compound.
- Protective seals over inlet and outlet tappings should not be removed until ready to connect piping.
Wiring:
- All wiring must comply with applicable electrical codes and ordinances.
- Power supply must be disconnected before making wiring connections.
- White leads of the thermopile connect to terminals with white dots.
- This valve is exclusively for self-generating power systems.
Fuel Conversion (RV8310E only):
- Involves removing the motor cover, pushing down and rotating the gas selector to align arrows with the appropriate colored screw (red for LP, blue for natural gas), inserting the corresponding fuel conversion plug (red for LP, blue for natural gas), attaching the conversion label, and replacing the motor cover.
- The high and low outlet pressure settings are fixed and cannot be changed during conversion.
Operation:
- Lighting the Pilot: Turn the gas control knob counterclockwise to PILOT, push down and hold, then push the piezo plunger until the pilot burner lights. The LED on the control will blink continuously after approximately 60 seconds. Release the knob.
- Turning on Main Burner: Turn the gas control knob counterclockwise to ON. If the manual switch is in LOCAL position, the main burner turns on immediately.
- Remote Control (with RT8220A Transmitter): For initial use, a recognition operation is required: Turn the gas control knob to PILOT, move the LOCAL/REMOTE switch to LOCAL for at least two seconds, then to REMOTE. Press the FAN or FLAME button on the transmitter within 30 seconds. The LED will blink, indicating transmitter functionality.
- Modulation: When in REMOTE position, the RT8220A Transmitter controls the main valve, flame modulation level, and fan. In LOCAL position, the receiver/valve operates at the highest fixed pressure setting.
- Shut-Off: Turn the gas control knob clockwise to OFF. This closes the main gas and safety valves, preventing the transmitter from turning on the main burner or fan.
Pilot Flame Adjustment: The pilot flame should envelop 3/8 to 1/2 in. (10 to 13 mm) of the thermocouple or igniter-sensor tip. Adjustment is made by removing the pilot adjustment cap screw and turning the inner adjustment screw. The cap screw must be replaced and tightened firmly after adjustment.

Maintenance Features

General: Regular preventive maintenance is crucial, especially in applications with heavy loads or exposure to water, dirt, chemicals, and heat.
Inspection Frequency:
- Cycling frequency: Appliances cycling 20,000 times annually should be checked monthly.
- Intermittent use: Appliances used seasonally should be checked before shutdown and again before the next use.
- Consequence of unexpected shutdown: Systems where a shutdown would be costly should be checked more often.
- Environment: In dusty, wet, or corrosive environments, the system should be checked more often due to accelerated deterioration of the gas valve.
Gas Leak Test:
- Performed by painting pipe connections with a rich soap and water solution; bubbles indicate a leak.
- Must be done upstream of the gas valve, and also on pipe joints (including adapters) and valve inlet/outlet with the main burner operating.
- Tighten connections if leaks are found; replace parts if leaks cannot be stopped.
Checking Gas Input:
- Can be done by clocking the gas meter (ensuring no other gas flow) and converting the flow rate to Btuh, then comparing to the appliance's input rating.
- Can also be checked with a manometer at the inlet and outlet pressure taps (which have captive screws).
Safety Shutdown Performance Test:
- Place the gas control knob in PILOT position (main burner off, pilot lit).
- Extinguish the pilot flame. The pilot gas flow should stop within thirty seconds, proving complete shutdown.
- Relight the pilot burner and operate the system through one complete cycle to ensure all controls function properly.
Prohibitions:
- Do not attempt to disassemble or repair the gas valve; it contains no replaceable components. Improper assembly can cause unreliable operation.
- Do not force the gas control knob. If it doesn't operate by hand, the valve must be replaced by a qualified service technician.
- The gas valve must be replaced if it was flooded with water or shows any physical damage (bent terminals, missing/broken parts, stripped threads, or heat exposure).
- Do not clean the gas valve.
- Any valve not performing properly on checkout or service should be replaced.
- Any module that is wet or appears to have been wet should be replaced.
