Read through these installation instructions carefully be-
fore tting the boiler. The installation instructions are ap-
proved in accordance with CE no. 048 AO-0006 for LPG
boiler type 2923. In connection with follow-up inspection
of the boiler, national regulations must be followed.
IMPORTANT WARNING!
No unit should be installed in any enclosed space unless
additional permanent ventilation of 100 cm
2
is provided.
No alteration or adjustment should be made to any
gas burner or gas supply by unauthorised or unskilled
persons. In the event of a failure or breakdown, turn off
the gas supply at the cylinder and contact the authorised
dealer or supplier.
The installation must be carried out in accordance with
the relevant British Standard of Practice. (Particulary
BS5482 Parts 1, 2 and 3).

FITTING THE BOILER2.
Mark out where the boiler is to stand. If the boiler is
to be positioned against a wall or bulkhead made of a
inammable material, a 1 mm air gap must be allowed.
Make holes in the oor, one for the ventilation duct and
one for the inlet pipe (see g 1). The ventilation duct can
be placed either on the right-hand side or the left-hand
side, depending on space available. Cover the hole for
the ventilation duct with ne mesh netting. Fit the chim-
ney according to chapter 2:2.
Put a strip of realant round where the boiler is to stand.
Position the boiler and screw it in place on the oor and
wall at A g 2.
The inlet pipe should be at least 25 mm under the oor
(see g 3). If not, use a extension pipe. Screw the black
inlet funnel to the inlet pipe under the boiler. Remove
the square panel on the side boiler where the ventilation
duct is to be tted by pressing the panel out from inside
the boiler casing and cutting the insulation around the
aperture with a sharp knife. Uncoil the overow hose
and pass down through the duct and out through the
hole in the oor. Screw the duct to the oor and the side
of the boiler.
If the boiler is tted in a cupboard a partition should be
installed to prevent inammable materials from contact-
ing hot parts of the casing etc. When immersion or water
heaters are tted cut holes in the partition, as g. 4 for
access to the water heater air cock and the overheat
reset button for overheating protection on the immersion
heater.
Mounting a boiler in a cupboard2:1
Mark out where the boiler is to stand. An air-space of
1 mm must be left if the boiler is to be placed next to a
wall or anything else that consists of ammable mate-
rial. A door or service hatch should be placed in front of
the boiler so that the control panel and the expansion
tank are easily accessible. The minimum distance in
front of the boiler to any ammable material should be
5 mm. Ventilation areas for the space which the boiler
is to occupy should be at least 10 cm
2
at the oor and
the roof. Make holes in the oor, one for the input tube
and one for the ventilation drum, if one is to be mounted
(see Figure 1 in the installation instructions). The ventila-
tion drum can be placed either to the left or to the right,
depending on the space available. Cover the hole pre-
pared for the ventilation drum with ne-meshed netting.
Then mount the chimney as described in Chapter 2:2.
Place a bead of silicone around the position where the
boiler is to be placed. Put the boiler into position and x
it by screws to the oor and wall (see Figure 2A in the
installation instructions). The input tube on 2923 must
protrude at least 25 mm below the oor (see Figure 3 in
the installation instructions); an extension tube must be
tted 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
