RV8310D,E MILLIVOLT RECEIVER/ MODULATING GAS VALVE
CHECKOUT
WARNING
Fire or Explosion Hazard.
Can cause property damage,
severe injury or death.
Do not force the gas control knob on the
appliance. Use only your hand to turn the gas
control knob. If the knob does not operate by
hand, the valve should be replaced by a qualified
service technician.
Gas Control Knob Settings
Gas control knob settings are as follows:
OFF: Prevents main gas flow through the valve.
ON: Permits main burner and pilot gas flow. Gas valve
and RT8220A Transmitter control main burner gas flow.
PILOT: Opens pilot valve and allows gas flow to the pilot
burner.
NOTE: NOTE:Valves are shipped with the gas control
knob in the ON position.
Perform Gas Leak Test
WARNING
Fire or Explosion Hazard.
Can cause property damage,
severe injury or death.
Stand away from the main burner while lighting.
Hidden gas leaks can cause flashbacks in the
appliance vestibule. Check for gas leaks with rich
soap and water solution any time work is done on
a gas system.
Gas Leak Test
1. Paint the pipe connections upstream of the gas
valve with a rich soap and water solution. Bubbles
indicate a gas leak.
2. If a leak is detected, tighten the pipe connections.
3. Light the main burner.
4. With the main burner in operation, paint the pipe
joints (including adapters) and valve inlet and
outlet with a rich soap and water solution.
5. If another leak is detected, tighten the adapter
screws, joints, and pipe connections.
6. Replace the part if the leak cannot be stopped.

Check and Adjust Gas Input and Burner Ignition
IMPORTANT
Do not exceed the input rating stamped on
the appliance nameplate, or the manufacturer
recommended burner orifice pressure for size
orifice(s) used.
IMPORTANT
For complete combustion, be sure the primary
air supply to the main burner is adjusted
properly. Follow the instructions of the
appliance manufacturer.
CHECKING GAS INPUT BY CLOCKING GAS METER
1. Be sure there is no gas flow through the meter
except to the appliance being checked.
NOTE: NOTE:Other appliances must remain off with
the pilots extinguished, or the consumption
must be deducted from the meter reading.
2. Convert the flow rate to Btuh as described in the
Gas Controls Handbook, form 70-2602.
3. Compare to the Btuh input rating on the appliance

to increase
3/8 TO 1/2 IN.
