Operating Instructions; Filling The Truma Boiler With Water; Draining The Boiler; Starting Up - Gas Mode - Truma BGF 10 Mode D'emploi

Operating instructions

Always follow the operating instructions before starting
up. The vehicle owner is responsible for correct operation of
the appliance.
The installer or vehicle owner must affix the yellow sticker
with the warning information, which is enclosed with the ap-
pliance, in a location in the vehicle where it is clearly visible
to all users (e.g. the wardrobe door). Missing stickers can be
requested from Truma.
Before using for the first time, the entire water supply
must be thoroughly rinsed with warm, clear water.
Always fit the cowl cover when the boiler is not in use. Drain
the boiler if there is a risk of frost.
No claims may be made under the warranty for damage
caused by frost!
The materials of the unit that come into contact with water
are safe for drinking water (see Manufacturer's Declaration,
www.truma.com – Manufacturer's Declaration).

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).

e = Lever position "Closed"
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 re-
sidual 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.

Draining the boiler

If the caravan is not being used during the frosty period,
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)

Never operate the boiler when it is empty.
If the cowl has been placed near or directly beneath an open-
ing window, 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 min-
ute before gas is available to burn. If the device switches to
"Fault", repeat the start-up procedure by switching off (wait
for 5 minutes!) and switching on again.

Switching off

Switch boiler off at control panel (c). Fit 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.

Red LED "Fault"

The red LED (a) will light up if there is a fault. Possible causes
are described on page 12. To clear the fault, switch device off,
wait for 5 minutes and switch on again.
The water temperature cannot be preselected, automatic
temperature limit at approx. 70 °C. The device 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 necess-
ary (close drain valve). Wait for 10 minutes, then switch on
again.

Maintenance

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 microorganisms.
Clean the device and the ventilation slots with a dry, lint-free
cloth.
