Air damper setting
• Dirt on burner blower wheel • Flue pipe setup or flue pipe restrictions • Gas manifold pressure • Heat exchanger • Air damper setting • Dirt on burner blower wheel • Flue pipe setup or flue pipe restrictions • Gas manifold pressure • Heat exchanger
• Rough setting at 1/2 open. Minor adjustments from the rough settings can be made to achieve a smooth sounding burner with no soot from the flue pipe. Insert volt meter probes into pr and – terminals on the Honeywell Flame Safeguard Control. Set the volt meter on DC volts and run the heater
.
Adjust the air damper until the volt meter reads the highest voltage between 2 and 5 volts. • Clean the burner blower wheel with a small brush • Refer to the flue pipe chart in this manual. Check flue for restriction
• Use a low pressure gauge (0-15 inches of water column) with 1/8” NPT
inlet.
Install gauge in the pressure tap port located on the output side of the gas valve. Run the heater
.
Adjust the pressure by turning the pressure adjusting
screw (located on the input side top of the gas valve) counter clockwise until the gauge reads the proper manifold pressure. Refer to pipe sizing charts in the Heat W
agon Engineering Guide. Heater requires 9-14” W
.C. inlet pressure.
• Refer to the cleaning instructions in this manual.
