Gas Connection - Truma BG 10 Installation Instructions Manual

Cut off the venting hose about 20 mm below the vehicle floor
at a 45° angle relative to the direction of travel.

Make a hose connection (22) for the cold water supply be-
tween drain valve (14) and the elbow fitting (13 – lower tube)
at the boiler.
Route hot water supply line (23) from elbow fitting with built-
in aeration valve (12 – upper tube) to hot water consumption
points.
If a water supply is being installed in the vehicle, it must
be ensured that sufficient room is left between the water
hoses and the heat source (e.g. heater, warm air duct).
SC hose clips (part no. 40712-01) are suitable for fastening
the hoses to walls or the floor. These hose clips also make it
possible to route water hoses on the heater's warm air distri-
bution pipes to prevent freezing.
A water hose may only be routed at a distance of 1.5 m from
the heater at the warm air duct. The Truma SC hose clip can
be used for distances greater than this. With parallel routing
(e.g. through a wall) a spacer (e.g. insulation) must be fitted in
order to avoid contact.

Gas connection

Figure 12
The operating pressure of the gas supply is 30 mbar
and must be the same as the operating pressure of the
device (see type plate).
The 8 mm diameter gas supply pipe must be attached to the
connection (38) using an olive connection. The olives must be
selected according to the gas supply pipe used (for copper
pipes: brass insertion sleeves and olive included in scope of
delivery). Carefully counterhold (width across flats 16) with
another wrench when tightening.
Before connecting to the boiler, ensure that the gas lines are
free of dirt, swarf and the like.
The pipes must be installed in such a way that the device can
be removed again for service work.
The number of separation points in the gas supply line in
rooms used by persons must be limited to the technical
minimum.
The gas system must comply with the technical and adminis-
trative regulations of the respective country of use (e.g. EN 1949
for vehicles). National regulations and rules must be followed.
