VR8304 Intermittent Pilot Dual Automatic Valve Combination Gas
Control
Combination gas control for use in 24 Vac, gas-fired, intermittent
pilot appliances with capacities from 30 to 415 cfh.
• Controls include safety shutoff, manual valve, two automatic
operators, pressure regulator and pilot adjustment.
• Use with S86F,H; S860D; S8600F,H; S8610 and S90A,B Control
Modules.
• Compact size.
• Provide two automatic valves. Solenoid operated first automatic
valve opens on thermostat call for heat; closes when call for heat
ends.
• Diaphragm-operated second automatic valve opens under control of
regulator; closes if gas or power supply is interrupted.
• Meet codes requiring dual safety shutoff.
• Natural to LP and LP to Natural conversion kits available for
standard and slow opening gas valves.
• All adjustments, wiring connections and pilot outlet are accessible
from top of control.
• Adjustable servo regulator effectively maintains almost constant gas
output pressure under wide fluctuations in gas supply pressure.
• Compatible with ECO connector.
• ON-OFF lighting sequence.
