4. Continued

5. The heater

blows black

smoke out of

the vent stack.

• Gas valve

• Air damper setting

• Dirt on burner blower wheel

• Improper flue pipe setup or flue pipe

restrictions

• Gas manifold pressure

• Incorrect burner orifice size

• Restricted heat exchanger

• If there is power at the flame safeguard control and no power out to the

solenoid valve, replace the flame safeguard control. Check for continuity

between the terminals on the solenoid valve coil.

• Rough setting at 4.5. Minor adjustments from the rough settings can be made

to achieve a smooth sounding burner with no soot from the flue pipe.

• 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 3” W.C.(Propane) & 3.2” W.C.(Nat Gas). Refer to pipe sizing

charts in the Heat Wagon Engineering Guide. Heater requires 9-14” W.C. inlet

pressure.

• For propane, use size .201.

For natural gas, use size .261.

• Remove flue pipe and use a flashlight to inspect the inside of the heat

exchanger. The access panel is located in the front panel which is welded to

the flue pipe.
