2.1 INSTALLATION
Models “34E BF” with a hermetically sealed combustion cham-
ber and air supply circuit, may be installed outdoor.
Models “34I BF” with a hermetically sealed combustion cham-
ber and air supply circuit, may be installed in any room in the
home.
2.2 CONNECTIN UP SYSTEM
Wash all system pipes well before hooking them up with the
boiler to eliminate any residues which could compromise its
functioning.
The discharge pipe must be connected and extend the pipe
to ensure that any discharge is safety routed any.
THE BOILERS MUST BE INSTALLED STRICTLY IN ACCOR-
DANCE WITH THESE INSTRUCTIONS AND MEET THE
NATIONAL AS INSTALLATION STANDARD AS 5601.
AND ANY LOCAL WATER AND ELECTRICAL STATE AND
LOCAL OVERNMENT RE ULATIONS WHICH MAY BE
APPLICABLE.
For installations where the heater is connected to larger
systems, the additional volume will need to be taken into
account.
A temperature pressure relief valve may be needed.
An adhesive data plate is sticked inside the front panel; it con-
tains all the technical data identifying the boiler and the type
of gas for which the boiler is arranged.
2.3 CHARACTERISTICS OF FEEDWATER
To prevent lime scale and damage to the tap water exchan-
ger, the water supplied should have a hardness of no more
than 20°F. In all cases the water used should be tested and
adequate treatment devices should be installed.
2.4 FLUE TERMINAL POSITION MODEL “34I BF”
The outlet terminals for forced draught systems may be
located on the outer walls of the building. Fig 4 shows
approximate, non-binding minimum distances to be met for a
building of the type shown in fig. 4.
2 ENERAL REQUIREMENTS FOR INSTALLATION
Fig. 4

2.5 ELECTRICITY SUPPLY
The electrical connection is made to a standard 10 amp 3
pin outlet. It is essential that a positive earth be made for the
satisfactory operation of the boilers.
THIS MUST BE FITTED BY A QUALIFIED ELECTRICAN.
2.6 WATER SYSTEMS - ENERAL
– This appliance is designed for connection to sealed cen-
tral heating water systems.
– Check that the mains water pressure is sufficient to pro-
duce the required D. .W. flow rate, but does not exceed
the maximum D. .W. pressure (Table 4).
Where mains pressure exceed 6 bar a pressure reduc-
ing valve must be fitted in the D.H.W. inlet.
2.6.1 Treatment of Water Circulating Systems
The condition of the water in the system is of great impor-
tance. Treatment such as Fernox is recommended to reduce
the effect of sludge and scale on the efficiency of the heating
system.
2.7 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. 5.
b) The appliance is equipped with an internal by-pass that
operates with system heads ( ) greater than 3 m. The
maximum 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 (usu-
ally the bathroom radiator).
c) The following paragraphs outline the specifications of the
items fitted to the boiler.
2.7.1 Pump
The available head shown in fig. 5 is that in excess of the
appliance hydraulic resistance, i.e. that available for the
system at any given heating load up to the maximum out-
put in C. . mode.
Never reduce the pump speed below maximum as this will
reduce D. .W. output. The pump speed is indicated on the
side of the pump speed selector switch (if fitted).
2.7.2 System volume (total water content)
The following Table gives the maximum system volume that
the integral expansion vessel can sustain under different
charge pressure conditions.
If the system volume exceeds that shown, an additional expan-
sion vessel must be fitted and connected to the heating system
primary return pipe as close as possible to the appliance.
If an extra vessel is required, ensure that the total capacity of
both vessels is adequate.

NOTE: If the pressure gauge indicates 2.65 bar or greater
when the appliance is at maximum temperature with all
radiators in circulation an extra expansion vessel is
required.
2.7.3 Pressure gauge
A pressure gauge is mounted on the appliance facia panel.
2.7.4 Safety valve
A safety valve set at 3 bar (43.5 psi) is fitted to the appliance
and a discharge pipe is routed to outside of the appliance.
This discharge pipe should be extended to terminate safely
away from the appliance and where a discharge would not
cause damage to persons or property but would be detected.
The pipe should be able to withstand boiling water, be a mini-
mum of 15 mm in diameter, and installed with a continuous fall.
2.8 D.H.W. SYSTEMS
– Check that the mains supply pressure is within the pre-
scribed limits (
Table 4
).
If necessary, a pressure reducing valve should be fitted to
the mains supply before the D. .W. inlet connection.
– A maximum D. .W. flow rate of: 14 l/m (3.1 gpm) is rec-
ommended. igher flow rates will not damage the appli-
ance but may lower the water temperature below an
acceptable level.
– If the appliance is installed in an area where the tempo-
rary hardness of the water supply is high, say over 150
ppm, the fitting of an in line scale inhibitor may be an
advantage. Consult the Local Water Undertaking if in
doubt.
– Devices capable of preventing the flow of expansion water:
e.g. non return valves and/or loose-jumpered stop cocks
should not be fitted unless separate arrangements are
made for expansion water.
– For specific information relating to fittings (eg. Showers,
washing machines etc.) suitable for connection in the
D. .W. circuit, consult the Local Water Undertaking, how-
ever the following information is given for guidance.
2.8.1 Domestic hot/cold water supply
taps and mixing taps
All equipment designed for use at mains water pressure is
suitable.
2.8.2 Showers
If a shower control is supplied from the appliance it should be
of the thermostatic or pressure balanced type.
Thermostatic type shower valves provide the best comfort
and guard against water at too high temperature.
Existing controls may not be suitable, refer to the shower
valve manufacturer.

3.1 FIXIN THE WALL MOUNTIN BRACKET
Before installing the appliance ensure that the chosen loca-
tion is suitable (section 2.2) and that the requirements for
flue position, (section 2.3), and minimum clearances, (
Table 2
)
are satisfied.
These minimum clearances are essential to provide access
for servicing, and are included on the wall mounting tem-
plates.
– Open the paper wall mounting templates. If a rear flue is
to be used, discard the side templates and secure the
rear template in the desired position. For a side flue appli-
cation, secure both the rear and appropriate side tem-
plate in position.
– Mark the position of the two wall mounting bracket fixing
holes and the flue/air duct hole on the appropriate wall(s).
– Remove the template(s) and drill the two fixing holes using
a 10 mm masonry drill. Fit the plastic plugs provided.
– Cut the hole in the wall for the flue/air duct. The diame-
ter should not be less than 100 mm (4 in) and must be
horizontal. Refer to fig. 12-14.
– 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. 6.
3.2 HAN IN THE BOILER
– Lift the appliance into position. The upper cross member
locates onto the wall mounting bracket.
– Screw in the wall mounting bracket adjusting screws until
the appliance is secure and vertical.
