Hot air system

• Identify the position of a hole in the floor for the pass through of the
air intake hose.
• Drill a hole in the floor with a diameter of 100 mm.
• Seal off the joint between the floor and the hose with temperature-re-
sistant sealing compound (up to 90 °C).
• Insulate the air hoses located outside to protect the water lines from
frost and to minimise the energy loss.
• Once inside the vehicle, guide the water pipes through the air intake
hose.
• Fasten the hose to the wall or floor.
9.2. Hot air distribution
Design an air distribution system that allows an even distribution of heat
into all heated sections of the vehicle. Design the system in such a way that
the air flow through both heater outlets is quite similar.
See the Webasto air and water heaters accessory catalogue for branches,
connecting pieces, Y-junctions, outlets, etc. made of high temperature re-
sistant materials.
The housing cover with hot air outlet (see Fig. 2) is equipped with two hot
air outlets to which the hot air hoses must be connected.
Both hot air outlets have to be used.
The internal diameter of the main section of the two hot air channels has
to be 80 mm.
Guide the hot air with 80 mm hoses directly from the heater into the inte-
rior.
• Connect 80 mm hoses to the housing cover with hot air outlet and fas-
ten them with screws to prevent them from sliding down during tem-
perature changes (see Fig. 2).
• Connect the whole air distribution system using air dividers and reduc-
ers. Drill holes in furniture and floor where necessary.
Through an appropriate selection of branches and diameters the air
flow and thus the heat flow can be influenced.
• Seal the gap between floor and hose, in case the hose is going from the
exterior to the interior of the vehicle.
• Mount Webasto air outlets at the end of each hose.
• Insulate hot air hoses routed to the outside to minimise energy loss.
