Continuous Pilot Boiler - VR8200A/VR8300A Gas Valve Operating Instructions
1. STOP! Read the safety information on page 16.
2. Set the thermostat to lowest setting.
3. Turn off all electric power to the appliance.
4. Remove lower front panel.
5. Rotate gas control knob slightly and turn clockwise

AUTOMATIC GAS VALVE
The Automatic Gas Valve opens or closes according to the
heat requirements of the thermostat and temperature limit
control. It closes if the pilot goes out. Each individual control
must be operating correctly before any gas can pass to the
burners. Any one control can hold the gas supply from burner
regardless of the demand of any other control.
SAFETY PILOT
Safety Pilot prevents the flow of gas to burner if the pilot goes
out, or will not ignite.
GAS VALVE SAFETY SHUTDOWN TEST
1. For boilers equipped with continuous pilot, with main burners
firing, disconnect the thermocouple from the gas valve. The
gas valve should immediately shut off the main burners and
the pilot.
2. For boilers equipped with intermittent ignition, with main
burners firing, disconnect the ignition cable from the
intermittent pilot control box. The gas valve should shut off
the main burners.
TURN OFF ELECTRIC POWER
reconnecting ignition cable, to prevent electric shock.
