Planar 2D-24 Installation Instructions Manual page 22

When installing the heater inside van bodies
(insulated vans, box vans, etc.) route the
exhaust pipe must be covered with duct or
some other type of protection. (Fig.20а)
When installing the heater inside van bodies
(insulated vans, box vans, etc.), the exhaust
pipe outlet and the air intake shall not be placed
on the opposite sides of the vehicle (Fig.21-
22).
The correct installation of the exhaust and air intake
pipes is on one side. The distance between them should
exclude re-suction of exhaust gases through the air intake (at
least 200mm).
As a result, normal operation of the burner is impeded, it
gets clogged with soot, and the life of the heater shortens
Under adverse conditions (strong wind, occasional
atmospheric pressure changes), failure to comply with these
recommendations not only prevents the discharge of exhaust
gases, but also creates an additional depression near the air
intake.
