Application

This gas valve is intended for use as a direct replacement component in compatible SCHWANK radiant heater systems. Two-stage gas valves allow the burner to operate at a reduced firing rate during lower demand periods and ramp up to full capacity when needed, reducing short-cycling and improving overall system longevity. Proper pressure ratings (5″ W.C. inlet / 3″ W.C. outlet) must be verified against your specific SCHWANK unit requirements before installation.

Installation Notes

• Verify compatibility with your specific SCHWANK heater model before ordering
• Ensure natural gas supply pressure matches the 5″ W.C. inlet specification
• Installation should be performed by a qualified HVAC or gas technician in accordance with local codes
• Consult the SCHWANK service manual for wiring and mounting specifications
