Proheat M Series Reference manual

AIR PRESSURE SETTING
RECOMMENDATION
(Diaphragm Compressor Models) for
Sustained High Altitude Operations.
Requirements
Test Procedure
a) Basic Hand Tools.
b) Proheat Remote Start Switch (P/N PK0091).
c) Proheat Digital Manometer Test Gauge (P/N PK0036).
d) Or Proheat Analog Air Pressure Test Gauge (P/N PK0067).
Sustained operation and servicing of the M-Series compressor above
4,000 ft (1219 m) requires the compressor setting be checked and/or
adjusted for proper combustion.
a) Disconnect all harnesses at the PCM.
b) Disconnect the fuel supply line.
c) Loosen and back out the burner head mounting (2) bolts five to
six turns allowing enough room to rotate the burner head 15°
counter-clockwise and remove.

SERVICE BULLETIN
Before adjusting air pressure, ensure
the Air Compressor filter and Fuel
Nozzle are clean. See service manual
at: www.proheat.com
NOTICE
To avoid the risk of shock and to
ensure that the PROHEAT does not
start, disconnect the Ignition
Module and Fuel Solenoid harness’s
at the PCM.

d) Remove Ignition Electrode Assembly. Use a flat head screwdriver
to gently pry the electrode assembly out.
e) Remove the Flame Shield. (Rotate to match the mounting square.)
f) Disconnect the Fuel Shut-off Valve and Ignition Module connectors
at the PCM. This ensures that fuel will not spray and/or light
during testing.
g) Remove the plug to the air pressure measurement port.
h) Thread in the Pressure Gauge and torque to 25 in-lbs ±3 in-lbs
(2.8 Nm ±0.3 Nm) as shown in figure B.
i) Connect ONLY the Power Harness and Remote Switch to the PCM.
Figure B. Air Pressure Test. Diaphragm Compressor Model.
j) Switch the PROHEAT on and observe the air pressure after one
minute, and compare to figure C, D or E on page 3 and page 4:
If Air Pressure is outside the recommended setting for your location
please ensure the fuel nozzle and air compressor filter are clean,
then check air pressure again.
k) Adjust the air pressure if necessary by turning the screw as
shown in figure B.
If the pressure cannot be set to the correct setting, rebuild kits
are available. See www.proheat.com for the latest parts manual
SL9167 for more information.

SERVICE BULLETIN
Leaving the Temperature Sensor
disconnected ensures that the burner
head will only run in Cool Down (Purge)
mode for three minutes.
NOTICE
If using PK0067, Analog air pressure
gauge, Calibrate gauge before each
use refer to: www.proheat.com/PDFs/

NOTICE
Connect power and switch only. DO
NOT connect the temperature sensor.

SERVICE BULLETIN

l) Turn heater off. Wait until cool down (purge) mode is complete
(approximately 3 minutes).
m) Remove test gauge. Lubricate air measurement port plug O-ring
with diesel fuel and reinstall plug into fuel block. Torque to 25
in-lbs ±3 in-lbs (2.8 Nm ±0.3 Nm). Re-install the Flame Shield,
the Ignition Electrode Assembly and Burner Head onto the Heat
Exchanger. Torque mounting bolts to 100 in-lbs (11.6 Nm ± 1.1 Nm).
n) Connect the Power, Dual Mode Temperature Sensor and Coolant
Pump electrical connections to the heater Burner Head and
reconnect the fuel line.
o) Activate the heater with the remote switch and observe operation
for at least one complete cycle. The heater should run smoothly
with no smoke although there may be some hesitation initially
due to air in the fuel line.
p) Remove the remote switch and re-connect the control
connection.
