Introduction
The main equipment of the MV MY20 Economie air 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
shaped case, which serves as an independent air passage. Cold air is drawn
into the air passage by the fan and blown out as hot air. The air is warmed to
around 90° above the ambient temperature. The heat can be supplied by the
heater to the driver’s cab and passenger’s compartment independently from
the engine, using ducting and joiners to accommodate most applications. The
basic schematic diagram is shown in Fig I.
The heater is fully automatically controlled. It features a compact structure,
easy installation, low running costs, easy maintenance and is safe and
reliable.

Installation
Installation of the Main Heater Body
For the ease of servicing, fault finding and air flow it’s recommended that the
main body is placed in an area with easy access. Figure V shows the minimum
distances required.

E. Exhaust outlet
Choose a flat installation surface, any undulations could cause the case to
twist and will not ensure an even mount. Make sure there are no foreign
bodies between the bottom of the heater and the installation surface itself.
This will ensure a good seal between the two.
