Alde COMFORT 2923 Montageanleitung Seite 9

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 cartridge.

2:1 Fitting the chimney.
Mark out the centre where the hole is to be made (see fig
6). Cut a Ø 125 mm hole in the ceiling and the insulating
material and a Ø 82 mm hole in the roof. Then assemble
the parts B,C and G and fasten the nuts H (see fig 5).
Then bring the chimney pipe in from underneath. Place
the boiler (chapter 2:0) and pull the chimney pipe down
and attach it to the stud on the boiler using a self-tap-
ping screw.
NB! When the chimney pipe is pulled up or down it
should at the same time be twisted (grease it with suds
if necessary).
Put on the cap and bend the retaining lugs inwards. The
distance from the roof to the cap should be at least 90
mm (see fig 2).
The exposed section of the chimney pipe inside must be
protected with mesh or metalsheet so that inflammable
material cannot come into direct contact with the exhaust
pipe (see fig 2 C).

2:2 LPG installation
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 service 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 caravan
:
7)
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 caravan
:
8)
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
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.

2:3 Fitting the room thermostat
The room thermostat should be placed at least 1 metre
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
circulation pump according to the heat requirement.
2:4 Electrical installation
12 volts
The electrical connection is made at the top of the boiler,
