Exhaust Pipe Connection

Asphyxiation risk! Exhaust pipes must be so routed that the possibility of exhaust fumes entering
the vehicle is unlikely.
Route the exhaust pipe in such a way as to prevent touching or being directed toward any part of
the vehicle that may be damaged by heat (i.e., brake lines, electrical wiring, hoses).
Additional flexible exhaust tubing is available from your Webasto Distributor or Dealer under part
number 900126.
One meter (39 inches) of flexible exhaust tubing has been supplied with the heater. Attach tube to
the heater with exhaust clamp supplied.
The exhaust tube should be routed in a gradual downward slope away from heater allowing
condensation to drain.
Secure exhaust tube to vehicle with fiP clip supplied. Keep exhaust tube at least 2 in. (50 mm) away
from heat sensitive materials.
The outlet opening of the exhaust tube must not point in the direction of travel to avoid any possible
clogging caused by snow, mud or foreign materials.

Combustion Air Supply

Never draw combustion air from inside the vehicle, or from areas where fumes or gases can
accumulate. Drawing of combustion air from areas where people are present is strictly prohibited!
A combustion air tube has been supplied with the heater. Looking at the tube, you will see one end
has a staple holding the inner liner and outer casing together.
The stapled end is the inlet end of the tube, the other end is to be attached to the heater.
To attach tube to the heater, stretch the outer casing about an inch further than the inner liner.
This will then slip over the inlet pipe of the heater and clamped in place.
Do not make any bends immediately after the attachment point to the heater. Doing so may cause a
restriction where the inner liner of the tube begins. Make all bends at least 3 inches away or further
from heater connection point.
The combustion air tube should be routed in a gradual downward slope away from heater allowing
moisture to drain.
The intake opening of the combustion air tube must not point in the direction of travel to avoid any
possible clogging caused by snow, mud or foreign materials.
Combustion air should always be taken from a clean area protected from road splash.
