V4295A,S; V8295A,S
Solenoid Gas Valves
APPLICATION
The electrically operated V4295A, S and V8295A, S Solenoid
Gas Valves control the flow of natural and LP (liquefied
petroleum) gases.
These valves are used on atmospheric boilers, commercial
water heaters, roof-top make-up air burners, power burners
and boilers.
INSTALLATION INSTRUCTIONS
FEATURES
• V4295A,S are used with 120 Vac controllers;
V8295A,S are used with 24 Vac controllers.
• Models available in Normally Closed and Normally
Open configurations.
• Normally Closed models, for safety shut-off
applications, consist of a direct on/off operator for
opening and closing of the valve.
• Normally Open models, for vent (double block and
bleed) valve applications, consist of a direct electric
on/off operator for closing and opening of the valve.
• Models are suitable for the control of gaseous fluids in
gas consuming appliances according to international
standards.
• Models have 1/4 inch NPT inlet and outlet pressure
taps.
• Models have inlet screen to protect the valve from the
entry of dirt.

    5. Check the power supply circuit. The voltage and fre- quency must match those of the valve. 6. Refer to Fig. 6 for typical V4295A,S field wiring with RM7800 (typical) Primary Safety Control. Refer to Fig. 7 for typical V8295A,S field wiring with Primary Safety Control.

  • Page 6: Checkout And Troubleshooting

    V4295A,S; V8295A,S SOLENOID GAS VALVES CHECKOUT AND TROUBLESHOOTING GROUND NEUTRAL WARNING Do not allow fuel to accumulate in the combustion chamber. If fuel is allowed to enter the chamber for longer than a few seconds without igniting, an LINE explosive mixture could result.

  • Page 7: After The Test

    Use utmost care during troubleshooting. Line USE ONLY ONE OF THE DOWNSTREAM TAPS ON THE SS0V. M9547F voltage is present at the actuator for V4295A,S and present in controller circuits. Low voltage (24 Vac) Fig. 8. Valve leak test. is present at the actuator for V8295A,S and present in controller circuits.

  • Page 8: Service Information

    Look for a short in the electrical circuit. Line voltage (120 Vac) should be present when the SERVICE INFORMATION primary safety control energizes the V4295A,S valve actuator. 24 Vac should be present when the primary safety control energizes the V8295A,S valve actuator.
