Exhaust gas connections coaxial
Exhaust gas lead-throughs
It is important to choose right part for right purpose. Coaxial exhaust gas lead-throughs 2467 , 5300 and 5400 are
recommended for Wallas unit. The ø 28/45 mm lead-throughs fit the exhaust gas hose 2448 , providing maximum wind
tolerance. All exhaust gas lead-throughs are stainless steel.
The exhaust gas tube reaches a high temperature! Be sure that the tube does not touch flammable materials and
double check the connections. Insulation sock
1030 is available as an accessory.
Safety distances
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
functioning 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.
Never place lead through near cabin fresh air intake. Make sure that
exhaust gases can never mix into fresh air intake.
Goose neck 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 circular.
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 section. 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 water.
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, 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.
An exhaust gas tube with a length of more than 2 meters (7’) has to be
equipped with a drainage lock
2471 (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
(3/32”) hole to the lead-through or to the exhaust pipe.
Heater takes makeup air for burner around the exhaust pipe. When 1030 insulation sock is used it's mandatory to leave
space between heater and insulation sock to make intake air flow possible.
