Installing the Fuel System
4.1 Before You Begin
For efficient and safe operation of the POLAR™ HD Heating Module,
follow all recommendations for properly installing the fuel system.
Any deviations from these must be approved in advance by ITR.
Use only diesel fuel, furnace oil, or stove oil in the POLAR™ HD
Heating Module. DO NOT USE GASOLINE, CRANKCASE OIL, OR ANY
OIL CONTAINING GASOLINE.
Keep fuel lines away from any heat source above 100°F (38°C).
Keep gasoline and any equipment that uses gasoline away from the
POLAR™ HD Heating Module location. The POLAR™ HD Heating
Module is not rated for use in an explosive environment.
Never share the fuel supply to the POLAR™ HD Heating Module
with any other fuel-burning device.
4.2
Fuel System Installation
The fuel pump in the POLAR™ HD Heating Module has a maximum
flow capacity of 25 GAL/Hr, and a maximum pressure of 11.5 psi,
and a maximum lift of 84”. A 10 micron fuel filter is recommended.
Select a fuel filter based on these requirements.
Recommendations for Installation
The POLAR™ HD Heating Module’s fuel connection is accessed from
the top of the heater. The fuel inlet, labelled, is located on the top
right of the POLAR™ HD Heating Module and consists of a 1/8” NPT
threaded female fitting. The fuel return, labelled, is located next to
the fuel inlet and consists of a 1/8” NPT threaded female fitting.
