- Page 2 Preface Thank you for choosing 5kW Air parking heater. This instruction book describes the structures, working principles, installation and operation of the air-heating parking heater. For correct use of the heater, please read this instruction book carefully before installation and use. The instruction book shall be saved in a convenient place for later reference.
- Page 3 1 Introduction The main equipment of Model 5KW parking heater (hereinafter referred to as the heater) is a small fuel furnace controlled by a single-chip micro- processor. Its furnace body (the heat exchanger) is located in the hood-shape case, which serves as independent air passage. Cold air is sucked into the air passage by the heat supplying fan and blown out when it becomes hot, so as to form another heating system that is to the original...
- Page 4 The furnace body (heat exchanger 15) is made of die-casting aluminum, with radiating fins around and at the rear end. Combustion pipe 22 （ include 12-Pipe base 13-Guide pipe）is installed in the inner cavity. The combustor core 20(include 19-Fuel pipe) with a protective hood is fixed on the front-end base 12 of the combustion pipe.
- Page 5 3.2 Hood-Shape Case The structure of the hood-shape case is shown in Fig. 4. It consists of the top cover 2 (The junction box cover 1 can be fixed on its window), bottom cover 4, air inlet hood 6, air inlet of heater 5 and hot air outlet 3. They form an air heating passage.
