Heater
Exhaust Connection - Typical
Create a swan neck in the exhaust to prevent water
ingress. The heater requires a dry exhaust, not
water injected.
Minimum bend radius:
Total bends
Combustion air pipe:
Exhaust pipe:
For every 90° of bend in combustion air and exhaust
pipes the exhaust system total length must be
de-rated by 500mm.
The exhaust from the heater must not be
connected to any other exhaust system.
Route the flexible exhaust, securely attached in such
a way that the heat cannot affect
adjacent plastic piping, electric cables etc.
The exhaust pipe should be wrapped in the woven
glass protective sock and secured with stainless ties
supplied with the kit. If addition protection is re-
quired, over-wrap with woven glass tape available
from your Webasto Dealer.

Exhaust Insulation
The skin fitting is normally fitted on the transom or
cockpit combing. The hull side is acceptable for motor
boats, but bear in mind the bow wave line and beam
sea risk. It must also not point in the direction of travel,
or be susceptible to high land wind pressure, which may
blow out the flame within the heater.
Measure the diameter of the skin fitting to be fitted and
cut the hole using a hole saw.
A suitable pilot hole should be drilled first!
Do not fit the skin fitting below the water line.
Do fit the skin fitting as high as possible to stop
water ingress
Do make sure that exhaust clamps are tight to
avoid gas leakage
Do make sure the exhaust glasses cannot reach
the combustion air intake
Do not cover the exhaust with the heater running.
We recommend the application of a suitable high
temperature sealant being used on all the exhaust
connections sufficient to fill the corrugations in the
flexible pipe ONLY but not enough to block or impair the
exhaust system.
We recommend the use of Webasto PC diagnostics to
verify the exhaust emissions of the installation. Your
local Webasto agent can supply this instrument or may
be able to offer a commissioning / calibration service.
For CO2 emissions refer to the table of specifications in
this book.
