INTRODUCTION

1.1 Overview

Fig. 1

The main unit of this parking air heater (the

"heater") is a small, microprocessor-controlled,

fuel-burning furnace. Its heat exchanger is located

in a hood-shaped case with a separate air

passage. Cold air is sucked into this air passage by

the fan, and hot air blown out, forming a heating

system independent of the vehicle's original

heating system. In this way, a vehicle’s cab or

passenger compartment can be heated whether

or not the engine is running.A schematic diagram

is shown in Fig. 1.

5.5 Installation of Combustion Air System

5.5.1 Installing the Pipes

Only the combustion air pipe and exhaust pipe provided

with the heater may be used. The air inlet is an alumi-

num pipe bellows, the exhaust is a stainless steel pipe

bellows. These must be installed correctly, and in

particular CANNOT BE INTERCHANGED during installation

(eg the aluminum pipe bellows is only suitable for use as

the inlet, and cannot tolerate hot exhaust gasses.)

Please use the clamps provided to mount them tightly.

5.5.2 Direction of Pipes

Both the air inlet pipe and exhaust pipe shall exit the

heater in an outwards and downwards direction. If

either of these pipes must be bent, the sum of the

angles of all its curves shall not exceed 270°. Please

refer to Fig.20, below.

The pipes openings shall not face towards the direction

of the running vehicle, or be positioned in way that

allows blockage by slurry, snow or dirt.

- Air for combustion must be fresh air sucked in from outside the vehicle; fumes from combustion must be discharged to outside the

vehicle via the exhaust pipe.

- The combustion air intake must remain free from any blockage at all times.

- The combustion air intake must be positioned to be sure that exhaust fumes cannot be sucked in mixed with the combustion air.

- The combustion air intake system shall be installed sloping slightly downwards.

- Where pipes pass through the vehicle’s outer walls or underside, please take measures to prevent entry of water splash into these pipes.

5.5.3 High Temperature Exhaust Pipe

When the heater is running, the surface of the exhaust

pipe will reach a high temperature. Ensure that this pipe

is installed far away from plastic components or other

objects with the poor thermal resistance on the vehicle

body. The exhaust pipe shall be properly mounted, with

its vent pointed downwards and perpendicular to the

road, at an angle of 90°±10° (see Fig. 21). To maintain

the correct angle, the exhaust pipe fixing clamp shall be

mounted within 150 mm of the pipe end.

5.5.4 Protective Cover

If the exhaust pipe section installed within the vehicle

may be touched by an occupant, a protective cover must

be installed to prevent human contact and skin burns.

The exhaust wrap tape provided can withstand high

temperatures, up to about 500 ºC.

please wear safety gloves while wrapping the exhaust pipe.

All types of combustion produce high temperatures

and toxic exhaust fumes; this is the reason the exhaust

system must be installed strictly according to these

instructions.

Do not perform any work on the exhaust system while the

heater is working.

Before working on the exhaust system, first switch the heater off,

wait until all parts have cooled down completely, and wear

safety gloves if necessary.
