Chassis Maintenance

Decal Locations

Auxiliary Engine System

Fluid Heater System P REPLACE BURNER FUEL FILTERS P CLEAN PUMP STRAINER Clean the line strainer between the type I tank and pump. Inside the fuel pump is a screen for straining out large particles from going through the system. Once annually, this screen should be removed and cleaned. The screen is accessed by removing the top of the fuel pump. Replace burner fuel filters.

Fluid Heater System PM INSPECT HEATER COILS FOR CARBON BUILDUP Visually inspect the coil of the heat exchanger for carbon build up or blockage. With the gun assembly removed, inspection can be accomplished with a drop light or flash light.

Fluid Heater System P Inspect Burner Gun Assy. Remove gun assembly in the burner and inspect for component wear or deterioration.

Fluid Heater System P Inspect Burner Gun Assy. Replace electrodes, insulators and buss bars. ElectrodeInsulatorBuss Bar

Fluid Heater System P Inspect Burner Gun Assy. Clean excess carbon residue off gun assembly. Acceptable Gun Not Acceptable Gun

Fluid Heater System P Inspect Burner Gun Assy. Clean flame detector cad eyes. Cad Cell Primary Control

Fluid Heater System P Inspect Burner Wiring P Inspect Burner Fuel Lines

Fluid Heater System P CHECK BURNER TRANSFORMERS Test transformer for strong arc. Arc should be tested with screw driver across the two transformer posts. Spark should jump approximately 5/8". Reinstall gun assembly and align transformer posts with electrode buss bars.

Fluid Heater System P SERVICE HEATER BLOWERS Inspect blower “squirrel cage”. Ensure squirrel cage spins freely. Apply lubricating oil to the bearings on the blower motor via the lubricating tubes. Blower Motor Squirrel Cage Fuel Pump

Fluid Heater System P INSPECT FOR EXCESS FUEL Look for excess fuel in and around the blower motor, squirrel cage, and fuel pump. Blower Motor Fuel Pump

Fluid Heater System P INSPECT THERMOCOUPLES Visually inspect thermal couple between fuel pump and blower motor for cracking and or wear.

Fluid Heater System P INSPECT FLOW SWITCHES Inspect flow switch bonnets for excessive wear and debris. Test the sliding mechanism for smooth operation.

Fluid Heater System P REPLACE BURNER FUEL NOZZLES Replace burner fuel nozzles with correct type for fuel being used in station.

Fluid Heater System P OPS-CHECK HEATERS Start and run individual heaters for operations check. 123
