Installation of the exhaust pipe
.
When installing the exhaust pipe, take into
consideration high temperature of the exhaust
pipe when heater is in operation. Cut the
exhaust pipe (flexible crinkled metal hose,
maximum length – 1.5 meters) to the
necessary length. It is advised to use two-layer
exhaust pipe when installing the heater.
Attach the exhaust pipe (Fig.10) using clamps
and install it so that it is slightly inclined to the
bottom in the direction of exhaust. Install heat
insulation on the exhaust pipe to protect
individual sections of the vessel (wiring or
other heat-sensitive objects).
Fig. 10 – Attachment of the metal hose to the
heater
Make longitudinal cuts (about 15mm) on ends of the metal hose to ensure better sealing
when connecting the heater pipe to the pipe for discharge of exhaust gases through the board
of the vessel, but without going beyond the pipe to be covered.
The exhaust pipe needs additional insulation at every connection of the
metal hose, for example, using a heat resistant tape or sealant.
The end of the metal hose should not contact the rubber seal of the heater. Exhaust
gases are discharged overboard the vessel. Install the discharge of exhaust gases in a
location inaccessible to water (at least 60 cm above the waterline) and to avoid the
possibility of repeated intake of exhaust gases by the air intake pipe. It is advised to install
the discharge of exhaust gases in away, that does not allow exhaust gases to flow inside the
cabins (e.g. away from open windows, doors), to avoid the possibility of inhaling dangerous
exhaust gases.
Do not place the output opening of the exhaust pipe in front of the
incoming airflow of the moving vessel.
To install the exhaust pipe adapter, drill a hole Ø 46
+1
mm in the hull of the vessel and
install the exhaust pipe into it as per Fig.11 with the pipe looking upwards (to avoid
penetration of water). Install a rubber gasket between the flange of the exhaust pipe and the
hull of the vessel to heal the connection. If additional sealing is necessary, use a thermally
stable sealant.
