Lead-throughs

FEATURES AND RECOMMENDATIONS FOR USE

Exhaust lead-throughs:

- Exhaust lead-throughs are intended primarily for use
with Wallas products in which combustion air is not
drawn from a suction air pipe located around the
exhaust pipe.

- Exhaust lead-throughs may be used in other Wallas
products if the suction pipe for the combustion air is
cut off before the lead-through.

- With devices where the exhaust pipe shall be
insulated with a larger diameter metal pipe, the
combination lead-through has to be used.

- Exhaust lead-throughs are intended primarily for the
following Wallas units: 95DU, 95DP, 800, 900, 1000,
90, 100, 150.

- It is possible to use the 602293 drainage lock with
the exhaust lead-throughs to remove occasional
splash water and condensation from the exhaust
pipe.

- All of the exhaust lead-throughs are st ainless steel.

- The exhaust lead-throughs fit into the ø 28 mm 1028
exhaust pipe.

3467 Standard lead-through:

- The standard lead-through may be used as a hull
lead-through in rough conditions and as a deck lead­through in mild and normal conditions.

- The standard lead-through has the best splashguard
of all Wallas lead-throughs.

- The standard lead-through cannot be sealed. For this
reason it cannot be used as a deck lead-through,
which may be occasionally submerged under water.
The standard lead-through’s splashguard is more
effective than using a sealable lead-through in the
open position.

- The standard lead-through withstands wind well and
may therefore be used as both hull lead-through and
deck lead-through.

- The arched design of the standard lead-through
makes it easier, for example, to slide a rope over it.
Likewise, a standard lead-through used in the hull
will not get caught if the hull comes into contact
with a post, for example.

1066 Hull lead-through:

- The hull lead-through has a slight flow resistance
and thermal effect surrounding it.

- The hull lead-through is sensitive to wind; under some
circumstances the wind can blow directly into the
hole. A strong wind exceeding 15 m/s may shut the
unit off.

2466 Sealable deck lead-through:

- The sealable lead-through withstands wind well.

- The lead-through may be installed into the deck
because of its sealability. It is therefore suitable in
rough conditions in which the deck may become
submerged under water.

- Always remember to open the lead-through before
turning the unit on and to seal it when sailing
conditions become rough.

- The lead-through is opened and sealed by
simultaneously pressing and turning its cap.

- Under exceptionally rough conditions, the use of the
deck lead-through upgrade, 2069, is recommended.

Combination lead-throughs:

- Combination lead-throughs contain both the exhaust
and combustion air jacket tube in the same lead­through.

- Combination lead-throughs are intended primarily for
Wallas products in which the combustion air is pre­heated in the suction pipe around the exhaust pipe.

- The combination lead-through may also be used in
other Wallas units if the splash guard of the fresh air
duct is taken care of for example with an insulation
pipe which is cut of after a gooseneck.

- With devices where the exhaust pipe shall be
insulated with a larger diameter metal pipe, the
combination lead-through has to be used, although
a combustion air is taken otherwise.

- Combination lead-throughs are intended primarily for
the following Wallas units: 96D, 1300, 1800, 2400,
3200, 30D, 40D.

- All combination lead-throughs are stainless steel.

- Combination lead-throughs fit the ø 28 mm exhaust
pipes and the ø 45 mm jacket tube, 2448.

3468 Standard lead-through:

- The standard lead-through is suitable for use as a
hull lead-through in rough conditions and as a deck
lead-through in mild and normal conditions.

- The standard lead-through has the best splashguard
of all Wallas lead-throughs.

- The standard lead-through cannot be sealed. For this
reason it cannot be used as a deck lead-through,
which may be occasionally submerged under water.
The standard lead-through’s splashguard is more
effective than using a sealable lead-through in the
open position.

- The arched design of the standard lead-through
makes it easier, for example, to slide a rope over it.
Likewise, a standard lead-through used in the hull
will not get caught if the hull comes into contact
with a post, for example.

2467 Hull lead-through:

- The combination lead-through increases the wind
tolerance of the hull lead-through to some extent as
long as wind blowing directly into the pipe does not
completely offset it.

- The thermal effect on the hull of the boat is in all
cases minimal, because the suction pipe serves as
a thermal insulator.
