3.1 Fuel pump Wiring

A 7m fuel pump harness (Fig 14) is supplied in the kit to connect to the fuel pump. Blue and brown, twin core

harness connects to the two black wires out of the combustion air inlet (Fig 3) (3). Polarity does NOT matter.

Plug kits are supplied; spade terminals or standard automotive electrical connections can be used.

Note: Never run the wires through the combustion air inlet tube, as it will create air restrictions. Ref: Section

2 – (2.4 & 2.5)

3.2 Installation of Control Element

Install the control element in a convenient location. The control element does not measure temperature. The

monitoring of temperature is registered via a return air temperature sensor located inside the heater.
