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. The boiler should be
installed in accordance with the Gas Safety
Regulations.
It is important that the condensate trap
be filled prior to operating the boiler. The
trap can be filled by pouring water care-
fully into the inner flue connection prior to
installation of the flue. Care should be
taken not to allow any water to enter the
outer flue.
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 pro-
vided air vent in the room or compart-
ment in which the appliance is installed.
2.2
FIXING THE WALL
MOUNTING BRACKET
– Using the template supplied,mark the
position of the two wall mounting brack-
et 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.
– 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 system
in order to eliminate any foreign bodies that
might be detrimental to the operating efficien-
cy of the appliance. When making the
hydraulic connections, make sure that the
clearances indicated in fig. 1 are respected. To
facilitate the hydraulic connections the boiler
is equipped with a valve pack code 5184817A
complete with instructions 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.
Gas Connection
: The gas connection must
be made using seamless steel or copper
pipe, galvanized and with threaded joints
provided with gaskets, excluding three-piece
connections, except for initial and end con-
nections. 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 (con-
sumption) 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 pres-
sure 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 iden-
tifying the boiler and the type of gas for
which the boiler is arranged.
Connection of condensation water trap:
To
ensure safe disposal of the condensate pro-
duced by the flue gases, reference should be
made to BS6798:2009.
The boiler incorporates a condensate trap
which has a seal of 75mm, therefore no addi-
tional trap is required. It is recommended that
20mm waste pipe is connected to the con-
densate trap with the use of a 20mm solvent
weld socket or elbow.
The condensate should ideally be discharged
internally into an internal waste pipe(washing
machine/sink waste) or a soil pipe to avoid the
risk of freezing.
2.3.1
Dealing with condensate (fig.4/a)
Five suitable drainage points
It is strongly recommend that the conden-
sate drain pipe and its termination are
made internally.
Five suitable drainage points:
1. Internal drain stack pipe
2. Waste water pipe*
3. External drain or gully*
4. Rainwater hoppers that carry both rain
water and foul water*
5. Purpose-made soakaways
* Care should be taken not to contaminate
any “Grey Water Systems”
Pipework
Condensate pipework should be plastic,
same as used for standard wastewater
plumbing. The advised method of connection
to the condensate trap is by using 20mm
overflow pipe with a socket attached to
cover the condensate trap connection.
Similarly the drainage system where the
condensate discharges to should also be
resistant to the acid condensate.
Pipework should be kept as short as possi-
ble. External runs should be avoided, but
when necessary be a minimum of 3 meter
in 32 mm diameter pipework and lagged
using water resistant material, to avoid
freezing, this also applies to pipe runs in
unheated areas such as garages.
