installation instructions).

permissible curve radius: see device-specific installation instructions).
• No contact with temperature-sensitive objects such as electrical cables, water pipes, plastic
parts, sails or boat hull.
• Minimum wall distance: ≥ 20 mm.
• Minimum pipe diameters; see device-specific installation instructions.
5.3.2 Exhaust gas pipes in personnel accommodation
WARNING! Avoid installing the heater and exhaust pipes in personnel accommodation
if possible. (Danger of suffocation if routing is inappropriate)
• If unavoidable: use rigid stainless steel pipes with a wall thickness ≥ 1mm.
• Replace pipes with new ones after ≤ 10 years.
• Make the joints especially precise and gas tight.
• Use high temperature resistant sealing compound.
