2.12.1 Installation of a supplementary heating system
If it is necessary to have a supplementary heating system, it is recommended to use the types foreseen by IVECO.
For vehicles for which IVECO does not foresee these heaters, they must be installed in compliance with the requirements of the
equipment manufacturer (e.g. positioning of the heating unit, pipes, electrical system, etc.) and in accordance with the information
provided below.
The supplementary heating system must comply with all the applicable national requirements (e.g. tests, particular versions for the
transport of hazardous goods, etc.) and must not use vehicle devices subject to the obligation of homologation if this use can have
a negative impact on performance.
Keep also the following in mind:
- protect the correct operation of the other vehicle systems (e.g.: engine cooling);
- check that the capacity of the batteries and the power of the alternator are sufficient for the highest current absorption (see
Chapter 5.4) and provide a protective fuse on the new circuit;
- for the delivery of the fuel, connect the supply system to a supplementary tank positioned on the pipe returning the fuel to the
engine. The direct connection to the vehicle tank is only permitted if it is done independently of the engine power supply and
if the new circuit is perfectly sealed;
- define the path of the pipes and the electrical cables (and the positioning of the flexible joints) based on the dimensions and
the influence of heat on the various chassis components. Avoid exposures that could be dangerous and use suitable guards as
necessary.
The entire positioning of the system must provide good access and permit quick maintenance.
The fitter must provide the necessary instructions for servicing and maintenance.
a) Water heaters
When the original vehicle heating and engine cooling circuits are involved (see Chapter 2.10), in order to ensure proper system
operation and guarantee the safety of the original one, the following is necessary:
- carefully define the connection points between the added system and the original system, in agreement with IVECO if
necessary. The added pipes must be in copper or another alloy that resists the corrosion of the coolant and the coupling
sleeves must comply with the requirements of IVECO standard 18-0400;
- foresee a rational positioning of the pipes, avoiding constructions or siphon paths;
- use deaeration valves (bleeding points) to guarantee proper system filling;
- ensure the possibility of completely emptying the circuit, providing supplementary plugs;
- use suitable protections as necessary to limit heat loss.
b) Air heaters
With these heaters and in they case they are positioned directly in the cab, pay particular attention to the exhaust (to prevent
the combustion gas from remaining inside the vehicle) and to the correct distribution of the hot air (to avoid direct flows).
