The boiler must be installed in a fixed loca-
tion and only by specialized and qualified per-
son in compliance with all instructions con-
tained in this manual. Furthermore, the
installation must be in accordance with cur-
rent standards and regulations.
2.1 VENTILATION REQUIREMENTS
Detailled recommendations for air supply
are given in BS5440:2. The following notes
are for general guidance:
– It is not necessary to have a purpose
provided air vent in the room or com-
par tment in which the appliance is
installed.
2.2 FIXING THE WALL
MOUNTING BRACKET
– Mark the position of the two wall mount-
ing bracket fixing holes and the flue/air
duct hole on the appropriate wall(s).
– Drill the top two fixing holes using a 10
mm masonry drill and fit the plastic
plugs provided.
– Cut the hole in the wall for the flue/air
duct. The diameter should not be less
than 100 mm (4 in) and must be hori-
zontal. If the hole is not accessible from
the outside of the building, its minimum
diameter should be sufficient to allow
the insertion of the wall liner (130 mm -
5 1/4 in diameter) which will be sealed
with mortar.
– Accurately measure the wall thickness,
and note this dimension for later use.
– Secure the wall mounting bracket in
position using the screws provided.
Ensure that it is the correct way up, as
indicated in fig. 4.
2.3 CONNECTING UP SYSTEM
Before proceeding to connect up the boiler,
you are recommended to flush out the sys-
tem in order to eliminate any foreign bodies
that might be detrimental to the operating
efficiency of the appliance. When making
the hydraulic connections, make sure that
the clearances indicated in fig. 1 are
respected. To facilitate the hydraulic con-
nections the boiler is equipped with a valve
pack code 5184803 complete with instruc-
tions sheet.
A safety valve set at 3 bar is fitted to the
appliance, the discharge pipe provided
should be extended to terminate safely
away from the appliance and where a dis-
charge would not cause damage to per-
sons or property but would be detected.
The pipe should be a minimum of 15 mm Ø
and should be able to withstand boiling
water, any should avoid sharp corners or
upward pipe runs where water may be
retained.
The gas connection must be made using
seamless
steel or copper pipe
(Mannesmann type), galvanized and with
threaded joints provided with gaskets,
excluding three-piece connections, except
for initial and end connections. Where the
piping has to pass through walls, a suitable
insulating sleeve must be provided.
When sizing gas piping, from the meter to
the boiler, take into account both the volume
flow rates (consumption) in m
3 /h and the
relative density of the gas in question. The
sections of the piping making up the system
must be such as to guarantee a supply of
gas sufficient to cover the maximum
demand, limiting pressure loss between the
gas meter and any apparatus being used to
not greater than 1.0 mbar for family II
gases (natural gas). An adhesive data badge
is sited inside the front panel; it contains all
the technical data identifying the boiler and
the type of gas for which the boiler is
arranged.
2.3.1 Connection of condensation
water trap
The drip board and its water trap must be
connected to a civil drain through a pipe
with a slope of at least 5 mm per metre to
ensure drainage of condensation water.
The plastic pipes normally used for civil
drains are the only type of pipe which is
appropriate for conveying condensation
to the building’s sewer pipes.
2.3.2 Requirements for
sealed water systems
The heating system design should be based
on the following information:
a) The available pump head is given in fig. 16.
b) The appliance is equipped with an inter-
nal by-pass that operates with system
heads (H) greater than 3 m. The maxi-
mum flow through the by-pass is about
300 l/h. If thermostatic radiator valves
are to be installed, at least one radiator
should be without a thermostatic valve
(usually the bathroom radiator).
2.4 CHARACTERISTICS
OF FEEDWATER
– All recirculatory systems will be subject
to corrosion unless an appropriate
water treatment is applied. This means
that the efficiency of the system will
deteriorate as corrosion sludge accu-
mulates within the system, risking dam-
age to pump and valves, boiler noise
and circulation problems.
– For optimum performance after installa-
tion this boiler and its associated central
heating sys t em mus t be f lushed in
accordance with the guidelines given in
BS 7593 “Treatment of water in domes-
tic hot water central heating systems”.
– This must involve the use of a propri-
etary cleanser, such as Sentinel X300
or X400, or Fernox Super floc. Full
instructions are supplied with the prod-
ucts, but for immediate information
please contact GE Betz (0151 420
9563) or Fernox (01799 550 811)
directly.
– For long term protection against corro-
sion and scale, after flushing it is rec-
ommended that an inhibitor such as
Sentinel X100, or Fernox MB-1 or Copal
is dosed in accordance with the guide-
lines given in BS 7593.
Failure to flush and add inhibitor to
the system may invalidate the appli-
ance warranty.
– It is important to check the inhibitor
concentration after installation, system
modification and at every service in
accordance with the manufacturer’s
instructions. (Test kits are available
from inhibitor stockists).
– At every service the Aquaguard Filter
(4.9) should be checked and cleaned.
2.5 COAXIAL DUCT ø 60/100
The air inlet-smoke outlet assembly, code
8096201, is included in the standard sup-
ply of the appliance complete with mounting
instructions.
