3.4 Heating Air Supply
Heating air is taken from inside the room or from
outside.
Outside air should come from spaces protected from
rain, splashes and dirt, it should not be exposed to water
when the vehicle is crossing puddle, river, etc.
Hot air outlets should be placed in such a way
that air does not come in contact with parts
susceptible to damage by high temperature.
Do not crush or flatten hot air ducting. Duct
diameter should be greater than or equal to the
diameter of the output fitting of the heater.
Heating ducts should be manufactured only
from materials with heat resistance of at least
130°C.
If the heater is operating with air recirculation, avoid
sucking the flow of heated air into the air intake heater,
Fig.13.
Installation of air ducts to the air heater
PLANAR-8DM is forbidden
When using a mounting box, outlet should be sealed in
such a manner that the box itself did not get hot air.
3.5 Combustion Air Supply
Air needed for combustion should not be sucked
from the cabin or luggage compartment of a
vehicle.
Inlet of the intake pipe should be positioned in such a way
that it is protected from sucking snow or getting clogged, and
if any water gets into it, it should freely drain out.
For boat application combustion air intake should be
connected to thru-hull fitting (supplied separately).
3.6 Exhaust System
Exhaust pipe, made from flexible corrugated metal, should
be cut to the required length.
The exhaust pipe is attached to the heater with a clamp.
For a better contact of the exhaust pipe and the heater fitting, a
few cuts of 15-20 mm in length should be made in the pipe, but
not beyond the exhaust fitting of the heater.
