Installation Of The Elbow Water Connectors; Installation Of The Safety (Pressure Relief) Drain Valve; Installation Of The Pressure Reducer; Water Pipe Routing - Truma B 10 Operating Instructions Manual

Installation of the elbow water connectors

Screw elbow with integrat-
ed breather valve (12) to
hot water connection pipe
(upper pipe) and elbow
without breather valve (13)
to cold water connecting
pipe (lower pipe).
Slide on nut (17), tension
ring (18) and O-ring (19).
Assemble screw connector
and connecting pipe and
fasten together using nut
(17).
Slide ventilation hose with
11 mm outer diameter (20)
onto the breather valve
hose nozzle (21) and route
towards the outside. Do
not allow the radius of the
arc to be less than 40 mm.
Cut off the ventilation hose
approx. 20 mm below the
floor of the vehicle at an
angle of 45° to the direc-
tion of travel.
In industrial bulk packs the water connections are preinstalled
and have to be tightened after the water pipes have been con-
nected. Please check for leaks before starting up for the first
time.
Installation of the safety (pressure relief)
drain valve
Install the safety/drain valve (14) at a place which is easily
accessible, near the water heater. Drill a hole with 18 mm
diameter and pass through the discharge tube. Fasten safety/
drain valve with two screws. The draining is to be directly to
the outside at a position protected against splash water (apply
splash guard, if necessary).

Installation of the pressure reducer

The pressure reducer (10) must be fitted between the safety/
drain valve and water pump in accordance to the direction
of flow. Fasten the pressure reducer to the floor.

Produce connection (16) for cold water supply between
safety/drain valve (14) and elbow (13 – lower pipe) on water
heater.
Route the hot water pipe (22) from the elbow with integrated
breather valve (12 – upper pipe) to the hot water consumers.

Gas connection

The gas inlet connection on the Boiler is a 14 mm met-
ric connection.
To connect, the UNF 1/2" - 20 (SAE Male AN Flare) gas inlet
connection provided with the appliance must be used.
Fig.18
For connection to 8 mm steel piping Truma povides an adapt-
er UNF 1/2" x RVS 8, part no. 70020-02700.
In industrial bulk packs the test connection is preinstalled and
has to be tightened after the gas line has been connected.
Please check for leaks before starting up for the first time.
Check for gas leaks (do not check for gas leaks with a naked
flame), then check that the gas pressure is as follows:
AUS: Propane gas – 2.75 kPa
NZ: LPG – 2.75 kPa
Before connecting to the water heater make sure that the gas
lines are free from dirt, chips and such!
Route the pipes in such a way that the appliance can be
removed again for servicing.
AUS:
Refer to AS5601 – Gas Installations, for gas pipe sizing.
NZ:
Refer to NZS 5428 – LPG installations
