• 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.

• On the heater control unit (HCU) disconnect the wires from terminals X12 and
X13. Using an ohm meter
, check the resistance between the two wires for a
reading. Compare to Sensor Resistance Chart page 25. If the test falls out of
this range, replace fan sensor
.
• T
urn the 3-position main switch to the fan position. If the blower runs, check the
fan sensor
. If it is good, replace the HCU.
