CONTROLS – GAS VALVE SUF 199 AND 250

ADJUSTMENT PROCEDURE: GAS PRESSURE SUF 199 AND 250 MODELS

IMPORTANT NOTE

THE SUF 199 AND 250 MODELS INCORPORATE A NEW GAS CONTROL, WHICH OPERATES AT A MANIFOLD PRESSURE OF 0" w.c. (0 kPa) FOR BOTH NATURAL AND PROPANE GAS. SEE THE GAS PRESSURE CHART ON PAGE 4. THESE MODELS ARE CONFIGURED PRIOR TO BEING SHIPPED FROM THE FACTORY AND NO ADJUSTMENTS ARE NECESSARY PRIOR TO STARTUP. THE CONTROLLER MONITORS THE AIR FLOW AND MAKES ADJUSTMENTS TO THE FAN SPEED WHICH IN EFFECT CONTROLS THE AMOUNT OF GAS FLOW. THEREFORE, THE UNIT WILL SELF ADJUST TO ACQUIRE THE CORRECT AMOUNT OF INPUT.

“Supply gas pressure to the water heater must not exceed a maximum of 10.5" w.c. (2.95 kPa) for natural gas, or 14" w.c. (3.45 kPa) for propane. The minimum supply gas pressure is 4" w.c. (.98 kPa) for natural gas and 9" w.c. (2.22 kPa) for propane gas.”

A supply gas pressure regulator (service regulator) must be installed on the gas supply line within 10' (305 cm) of the unit.

Once the unit is installed and filled with water and the inlet pressures confirmed, simply turn the switch “on” and observe operation. Cycle the unit “off” and “on” several times to ensure proper operation.

HIGH ALTITUDE INSTALLATION

The SUF 199 and 250 models are suitable for installation up to 10,100 feet above sea level with no adjustments.

GAS ORIFICE

The SUF 199 and 250 models do not have a natural gas orifice. A .230" orifice is used on LP gas models.
