3.4 Heating Air Supply Installation of air ducts to the air heater Heating air is taken from inside the room or from PLANAR-8DM is forbidden outside. Outside air should come from spaces protected from When using a mounting box, outlet should be sealed in rain, splashes and dirt, it should not be exposed to water such a manner that the box itself did not get hot air.

Exhaust gases should be discharged to the outside. The end of the exhaust pipe should not touch Furthermore, the gases should not adversely affect the operation the rubber sealing of the heater. of vehicle units. The outlet of the exhaust pipe should be in such a position that would prevent clogging or entering of snow, and When mounting the exhaust pipe, care should also provide for free drain of any water that got into it.

Both exhaust and intake pipes should be positioned When installing the heater inside van bodies inclined downward from the heater (Fig.16). If this is not (insulated vans, box vans, etc.), the exhaust pipe possible, then a hole Ø3 mm should be made at the lowest outlet and the air intake shall not be placed on point to drain condensate.
