Truma Combi boiler
The boiler is integrated in the heater system and operates on gas. The boiler
is switched on by turning the rotary switch (Fig. 86,2) on the operating unit
(Fig. 86).
In winter operation "Heater and boiler" (Fig. 86,3) the water is automatically
heated up when the heater is switched on. If the heater switches off after the
required room temperature has been reached, the boiler will continue to heat
up until the set water temperature has been reached.
In summer operation (Fig. 86,1) only the water in the boiler is heated up to
either 40 °C or 60 °C. The water is heated to 60 °C in approx. 25 minutes. The
yellow indicator lamp (Fig. 86,4) illuminates during the boiler heating-up
period.
The power supply for the appliance cannot be interrupted by means of the 12
V main switch. When there is a fault, the red indicator lamp (Fig. 86,4) on the
operating unit illuminates (see Chapter 14).
Safety/drainage valve
The boiler is equipped with a safety/drainage valve (Fig. 87). The safety/
drainage valve prevents water in the boiler from freezing, when there is frost
and the heater is not switched on.

drainage valve and drain the boiler.
Z
At temperatures below approx. 3 °C the safety/drainage valve opens auto-
matically. Before filling the boiler switch on the heater and wait until the
temperature of the safety/drainage valve exceeds 7 °C. Only then can the
safety/drainage valve be closed again.
Z
The water pump and the water fittings are not protected against freezing by
the safety/drainage valve.

The drainage neck of the safety/drainage valve has to be free of dirt (e.g.
leaves, ice) at all times.
