Marine heating system Installation Instructions

• Secure the hoses: with hose clamps on all joints.
• Recommendation for hose routing through areas not to be heated: fit hoses with hose
insulation to prevent heat loss (Webasto Thermoduct
®
available as accessory).
9.4.2 Silencers in air circulation
Recommendation: For Air Top 5000
®
systems with short hot air supply hoses, use a silencer in
the intake and/or outlet side (noise level reduction). See the parts catalog.
Hot air silencer for reducing the noise levels.
9.4.3 Air distribution and outlet
Through an appropriate air distribution, all the required areas in the boat can be evenly heated. To
this end, multiple side branches branch off the main line so as to reach all the cabins. Through an
appropriate selection of branches and diameters you can influence the air flow, and thus the heat
flow.
See the parts catalog for branches, connecting pieces, y-junctions, outlets, etc. made of
temperature-resistant material.
WARNING! Risk of injury. Do not direct hot air onto living beings or temperature-
sensitive objects.
• Hoses: keep them as short as possible (heat loss).
• Hose routing: straight if possible (large curve radii).
• Recommendation: use distributors with control shutters and Bowden cable controls
(regulation of the air flow as required).
• Maintain the hose diameter of the main hose continuously from the heater to the main outlet.
• The outlet from the main hose must not be shuttered in order to prevent overheating of the
heating system. Side branches: shuttered outlets are possible.
• Note: arrange the outlets so that they do not get blocked.
