the ventilation drum, if one is to be mounted (see Figure
1 in the installation instructions). The ventilation drum
can be placed either to the left or to the right, depending
on the space available. Cover the hole prepared for the
ventilation drum with fine-meshed netting. Then mount
the chimney as described in Chapter 2:1.
Place a bead of silicone around the position where the
boiler is to be placed. Put the boiler into position and fix
it by screws to the floor and wall (see Figure 2A in the
installation instructions). The input tube on 2923 must
protrude at least 25 mm below the floor (see Figure 3
in the installation instructions); an extension tube must
be fitted if it does not extend this far. Screw the black
input funnel onto the input tube under the boiler (only
valid for 2923).
Remove the square covering plate from the boiler where
the ventilation drum is to be attached. Roll out the plastic
hose that lies behind the lower front plate. Cut off the end
of the hose to make it pointed. Feed the hose out through
the ventilation drum and the floor. Attach the ventilation
drum to the floor and the boiler by screws.
If the boiler is to be mounted in a wardrobe, for example,
a dividing wall should be mounted so that flammable
material cannot come into contact with any warm parts.
If a water heater and electrical cartridge are mounted
on the boiler, make a hole in the dividing wall (2923
Figure 4 and 2928 Figure 3) in order to gain access to
the air-screw and drainage tap of the water heater and
to the reset button for the overheating protection on the
electrical cartridg
2:1 Fitting the flue terminal
Mark the centre of the position of the hole (see Figure 4
in the installation instructions). Make a hole of diameter
120-125 mm in the roof. Mount the chimney hood (Figure
5A) from above. Seal with silicone or jointing compound
and screw the chimney hood onto the outer surface of
the roof. The minimum distance from the roof to the lower
roof vane of the chimney is 80 mm (see Figure 6). Then
mount the input sleeve coupling (Figure 5B) by opening
the hose clip, threading it around the chimney hood and
pressing the coupling into the hole. Tighten the input sleeve
coupling onto the chimney hood with the hose clip.
Cut the chimney pipe (Figure 5C) so that it is about 60
mm longer than the distance between the boiler and
the chimney hood. Then feed the chimney pipe into the
chimney hood and put the boiler into position (Chapter
2:0 in the installation instructions). Pull down the chimney
pipe and attach it to the exhaust pipe of the boiler using
a sheet metal screw.
Mount the input tube between the sleeve couplings on
the chimney hood and the boiler, and fix it in place with
hose clips.
The free part of the chimney pipe in the vehicle must be
protected by netting or sheet metal so that flammable
material cannot come into direct contact with it (see
Figure 2C in the installation instructions).

The boiler should be attached to an LPG cylinder with a
type-approved regulator with a pressure of 28 mbar with
butane or 37 mbar with propane. A secure tap to cut off
the gas supply must be fitted before the boiler. The boiler
should be connected with 8 mm copper pipe. The pipe
must be secured carefully at 500 mm intervals througout
its length. If the copper pipe passes through walls, floors
or similar it should be protected against wear by a grom-
met or insulation.
If the copper pipe is run under the vehicle

In the base plate of the boiler there is a ready-punched
hole for the copper pipe to pass through. Drill a hole
through the floor where the copper pipe is to enter. Pull
the copper pipe up through the floor and the base plate
(donʼt forget to protect the pipe against wear). Use a
supporting sleeve, nut and olive (see fig 9) and screw
the pipe to the gas connection of the gas valve. Seal the
hole in the floor with silicon or similar.
If the copper pipe is run inside the vehicle

Remove the disc on the right or left-hand side of the metal
case, depending on which side the copper pipe comes
from. Cut a hole in the rubber washer and attach it where
the disc was. Push the copper pipe through and pull it up
(fig 5).
in a gentle curve to the gas valve. Use a nut and olive
(see fig 9) and screw the pipe to the connection of the
gas valve on the burner.

The room thermostat should be placed at least 1 m above
the floor, but not too close to the ceiling. It should not be
placed on an outer wall, beside the boiler, cooker, fridge
or flue. The room thermostat starts and stops the circula-
tion pump according to the heat requirement.

The electrical connection is made at the top of the boiler,
where a six-pole terminal block is fitted. Use the accom-
panying terminal plug and the five spade connectors.
