Exhaust gas lead-throughs
Exhaust gas lead-throughs 2467 and the closable model 2460 are suitable for de-
vice 22 GB and 30 GB. The ø 28/45 mm lead-throughs fit the exhaust gas pipe
2448.
Exhaust gas lead-throughs 1066 and the closable model 2466 is suitable for
device 40 Dt. The ø 28 mm lead-throughs fit the exhaust gas pipe 1028.
All exhaust gas lead-throughs are stainless steel.
General instructions for exhaust gas connections
LOCATION
Air must always flow freely past the lead-through. Install the lead-through on a flat
surface. Avoid corners or recessions where wind pressure can disturb the function-
ing of the device.
The minimum distance of the lead-through from the fuel tank's filler hole is 400 mm
(16").
The minimum distance of the side lead-through from the surface of the water is
500 mm (20"). Especially in sail boats it should be noted that the lead-through must
never be submerged.
It is recommended to place the lead-through in the side as far back as possible or
directly in the transom.
INSTALLATION
When preparing the installation cut-out for the lead-through, it is a good idea to use
the lead-through as a model for the cut-out; especially if the lead-through is circu-
lar. If necessary, seal the installation cut-out with silicone in addition to the lead-
through seal. Note! Do not use silicone on a wooden boat.
The side lead-through must always be equipped with a so-called goose neck sec-
tion.
The goose neck will effectively prevent splash water from getting to the device.
The highest point of the goose neck must always be above the surface of the wa-
ter.
The device will go out, if the exhaust gas lead through is submerged.
OTHER THINGS TO NOTE
Exhaust gas is hot. Always ensure that there is nothing that is susceptible to heat
damage within 200 mm (8") of the effective area of the exhaust gases (e.g. ropes,
K00047
fenders or the side of another boat).
All lead-throughs raise the temperature of their surroundings. A wooden deck, in
particular, may dry due to the heat. Remember that the surface of the lead-through
is hot during use.
A exhaust gas tube with a length of more than 2 meters (7') has to be equipped
with a drainage lock 602293 (condense water) located to the lowest point of the
tube.
The Exhaust gas pipe must be made of stainless steel.
If necessary, seal the connections between the exhaust gas pipe and the lead-
through with heat-resistant silicone.
When installing the lead-through to the stern side or to otherwise leaning position,
be sure that the water do not stuck the exhaust. Drill app. 2 mm (
lead-through or to the exhaust pipe.
