Approximate Capacity *Manifold Pressure Electrical Characteristics
U.S. Gals. Liters Gas Type “WC kPA Volts/Hz Amperes
34 129 Nat./LP 0 0 120/60 <7
50 189 Nat/LP 0 0 120/60 <7
* The manifold pressure is the factory setting and is not adjustable. A negative pressure will be seen with just the blower running without
the Gas Control Valve open.
All models - Maximum Supply Pressure: 14 inches W.C. (3.48kPa)
Minimum Supply Pressure for Natural Gas: 3.50” (.87kPa)
Minimum Supply Pressure for Propane Gas: 8.00” (1.99kPa)
Minimum pressure must be maintained under both load and no load (dynamic and static) conditions.
