Main requirements to installation of assemblies and units of the heater
Install the heater in a dry place that is protected from ingress of overboard water and
condensate, excessive vibrations and heat emissions, engine emissions or fuel or oil
contamination.
The heater must be installed following safety requirements and taking into account the
type of vessel. Consider everything related to peripheral equipment, for example, the
maximum permissible length of the exhaust gas channel, the location of the passage in the
board, air intake for burning, layout and length of electric wires, distance from the fuel tank,
layout of air ducts of warm air, intake of fresh air.
Consider the maximum heel of the vessel. A heel must not bring overboard water into
the discharge channel for exhaust gases, and bilge or overboard water must not get on the
heater.
All precautions should be observed when installing the heater to reduce the risk of
injuries to personnel or damage to the equipment as much as possible.
3.1
Installation of the heater
Install the heater, taking into consideration permissible operating position according
to Fig.1; take into account the possible heel of the vessel. Fig.1 shows two extreme
installation positions of the heater. The distance from surrounding objects must be sufficient
to ensure good ventilation; the distance from walls and partitions to the start of the inlet
opening of the heater must be no less than 50 mm (see Fig.1b). The distance from walls,
partitions to the start of the outlet opening of the heater must be no less than 250 mm.
Provide protection from penetration of foreign objects into intake and output openings,
when installing and operating the heater. Install the heater so that it is convenient to do
maintenance works.
