Fig. 1b – Distance from walls
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 50mm for AIR-2D/4D and 100mm for AIR-8D/9D (see Fig.1b). The distance
from walls, partitions to the start of the outlet opening of the heater must be no less than
150mm for AIR-2D/4D and 250mm for AIR-8D/9D. 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.
For installing air ducts, these distances need to be considerably greater (see “Section 5”,
for more information on air ducting).
DO NOT install near flammable or heat-sensitive objects such as sails,
fenders, clothing, sheets, paper, gas pipelines, fuel tanks, etc.
When installing the heater, make sure that the mounting flange is the only place of
contact with the mounting surface of the vehicle or vessel. The casing of the heater should
not contact any surface (Fig.2b), to avoid deformation of the heater casing, jamming of
the air blower fan and potential overheating.
Install the heater on a flat surface, because installing on uneven surface,
can bend the casing of the heater, thus blocking the fan (common cause of
error 27).
