Domestic gravity return, any one of the three remaining lower
connections may be used for the gravity domestic hot water
return.
Fit plugs into all unused connections.
NOTE, if only limited clearance is available it is recommended
that the front tappings are used.
4.4 Planning Water Connections - Fully
Pumped Systems
It is important that all connections are made as shown in
diagram 4.4.
Flow, either one of the two upper front connections may be
used,
Return the water distributor tube MUST be fitted into the return
connection on all installations, see diagram 4.3. The distributor
tube is packed in the top fitment.
4.5 Thermostat Pocket
Fit the thermostat phial pocket, supplied in the top fitment, into
the front tapping adjacent to the heating flow connection and
plug the other front pocket connection.
Carefully unwind the thermostat capillary, insert phial fully into
the pocket and secure with the location washer behind the
retaining split pin, supplied in the loose items pack, see diagram
4.5.
4.6 Pump Within Boiler Casing
If the pump is to be fitted inside the boiler casing, see diagram
6.2, ensure that a heat shield kit is obtained and fitted
(Kit No. 425839).
The kit contains a flueway cleaning door with heat shield
(attached).
4.7 Positioning/Connecting Boiler
If the boiler casings are to fit flush with any kitchen units, the
distance the boiler is away from the wall must be measured and
dimension “G” increased by this amount, see diagram 1.1.
Having selected the position of the boiler, mark out and cut a
hole through the wall where the boiler is to be installed, to the
dimensions shown in diagram 4.6, after checking that sufficient
clearances will be left around the boiler as described in Section
1.8 “Boiler Location”, refer also to Section 3.5 “Flue Duct
Length”.
Fit the distributor tube, see diagram 4.2 or 4.4 for position, see
diagram 4.3 for alignment. Fit appropriate fittings and plugs
into the boiler connections.
IMPORTANT NOTE, do not route any pipes across the front of
the boiler thermostat pocket, the controls, burner supply pipe,
combustion chamber cover or flueway cleaning door. The gas
supply pipe should be run along the left-hand side of the boiler.
If the flue duct length necessitates the use of the flue extension
kit, that is 410 to 610mm (16 to 24inches) this will need to be
assembled before positioning the boiler. Read the separate
instructions supplied with the kit in conjunction with Section 4.8
“Balanced Flue Terminal”.
When suitable installation clearances are available, position
the boiler in readiness to connect pipework.
If suitable clearances are not available it will be necessary to
preplumb the gas and water connections before positioning the
boiler.
When the front tappings are used it is essential that any
pipework of fittings be assembled as shown in diagram 4.7, that
is, do not stick out more than shown.
