Note: The motorhome control panel,
situated above the entrance door must be
switched on for the fan to operate. See
page 69.
Cleaning
(With switched off appliance!) We recommend
removing dust which has collected on the heat
exchanger and base plate of the heater and on
the impeller wheel of the Trumavent fan, once
a year before the heating season starts. Clean
the impeller wheel carefully using a brush or
tooth brush.
Butterfly outlets
The butterfly plate may be opened or closed
to control the quantity of air and may also be
twisted around to control direction.
For uniform distribution, outlets nearest the
heater should be closed more than those
further away.
Blown air
The air ducting outlets are generally of the
butterfly type and may be opened or closed by
adjusting the butterfly valves. Twisting the disc
in its housing directs the flow in the direction
required.
One outlet on each leg of the air ducting layout
must be kept open at all times. Under no
circumstances should the air ducting outlets
be blocked.
Truma Combination Boiler
The Truma Combination Boiler has been
designed to run on gas or electric power and
the optimum performance is obtained when
used in dual fuel mode, that is running on
gas and electric at the same time.
Running in dual fuel mode has the following
benefits:
• Fastest possible heat up time, the 2KW
gas burner combines with a 1.8KW electric
element to provide 3.8KW of energy to heat
your hot water and warm your motorhome.
• The intelligent heat management system
automatically senses when the water and
room are nearing the required temperature
and then automatically turns off your gas
burner and operates solely electric power,
conserving your gas.
• As hot water is used or the room cools the
Truma combination heater will continue to
operate on electric only until a point where
the demands necessitate that additional
gas power is required. An example for
such a demand could be for instance if the
exterior door was left open and the room
temperature dropped by 10 degrees in the
space of a few minutes, in this case the
intelligent heat management system would
decide that the best way to get the room
back to the required temperature would be
to use both gas and electric at the same
time.
Operating the Truma Combination system on
electric or gas only will result in longer heat up
times for hot water and the room temperature
in comparison to operating on dual fuel.
Operating on electric only may not in all cases
maintain a comfortable room temperature
especially in colder conditions.
