Operating Instructions Preparation; Filling The Truma Boiler With Water; Starting Up - Gas Mode; Red Led "Fault - Truma BGF 10 Mode D'emploi

Operating instructions
Preparation
The entire water supply must be thoroughly rinsed
with warm, clear water before being used for the
first time.
The installer or vehicle owner must affix the yellow warning
information sticker that is provided with the appliance to the
vehicle in a location that is clearly visible to all users. Missing
stickers can be requested from Truma.

Filling the Truma Boiler with water

Check that the drain valve in the cold water supply is closed:
the lever should be in the horizontal position (e).

f = Lever position "Drain"
Turn on the hot water tap in the bathroom or the kitchen.
In the case of thermostatic or single-lever mixer taps, set to
"warm".
Switch on the power for the water pump (main switch or
pump switch).
Leave the fittings open for as long as it takes for the boiler to
displace the air and fill up and for water to flow.
In the event of frost, filling may be prevented by frozen resid-
ual water. The boiler can be thawed by turning it on briefly (no
more than 2 minutes). Frozen lines can be thawed by heating
the interior.
Starting up – gas mode

Never operate the boiler when it is empty.
If the cowl has been placed directly beneath an opening win-
dow, the boiler must be equipped with an automatic shut-off
device in order to prevent operation with the window open.
Remove the cowl cover.

Open the gas cylinder and the quick-acting valve in the gas
supply line.
Turn the boiler on using the switch on the control panel (b).
When operating vehicle-specific switches:
see vehicle manufacturer's operating instructions or markings
on switches.
If the gas supply line is full of air, it may take up to a minute
before gas is available to burn. If the appliance switches to
"Fault", repeat the start-up procedure by switching off (wait
for 5 minutes!) and switching on again.

Red LED "Fault"

The red LED (a) will light up if there is a fault. Possible causes
are described on page 14. To clear the fault, switch the appli-
ance off, wait for 5 minutes and switch it on again.
The water temperature cannot be preselected, automat-
ic temperature limit at approx. 70 °C! The appliance can
be operated with gas and electricity simultaneously in order
to speed up the heating of the boiler contents.
The electric heating element is fitted with an overtem-
perature sensor. In the event of a fault, switch off at the
control panel. Check the water content, topping up if neces-
sary (close drain valve). Wait for 10 minutes, then switch on
again.

Switching off

Switch boiler off at control panel (c). Fit the cowl cover. Drain
the boiler if there is a risk of frost. If the boiler is not being
used for a long time, close the quick-acting valve in the gas
supply line and gas cylinder.

Draining the boiler

If the caravan is not being used during the frosty peri-
od, the Truma Boiler must be drained!
Switch off the power for the water pump (main switch or
pump switch).
Turn on the hot water taps in the bathroom and kitchen.
Open drain valve: lever vertical, position (f).
The boiler will now be drained directly to the outside via the
drain valve. Check that all the water has drained out of the
boiler (10 litres)

Cleaning

We recommend the use of suitable commercially available
products to clean, sterilise and maintain the boiler. Products
containing chlorine are not suitable.
The boiler should be heated to 70 °C at regular intervals to
prevent infestation by micro-organisms.
Clean the appliance and the ventilation slots with a dry, lint-
free cloth.
