care not to damage the probes or burner. Place the burner
assembly in a safe location. Fit the wall frame to the wall
plate using the four M6 nuts provided – see Figure 11.1.
Locate the compression/BSP adapter fitting for the gas
inlet pipe from the accessory pack and screw well down in
the appropriate socket of the wall frame using suitable
sealant. Select the gas inlet pipe and loosely fit the long
vertical leg to the wall frame connection – see Figure 10.6.
Lift the boiler module onto the wallplate, engaging the lugs
on the right hand side of the casing adjacent to the water
connections, onto the pins on the right hand side of the
wallplate – see Figure 11.1. Take care not to hit the gas
inlet pipe.
Caution the assembly weighs approx. 60kg
and should be lifted by two people. Alternatively, two
lifting eyes are provided for use with suitable lifting
equipment.
The pins are of different lengths to assist with
engagement. Fit the burner assembly back into the heat
exchanger using its existing fastenings. Swing the boiler
module back to the wallplate whilst carefully aligning the
short horizontal leg of the gas inlet pipe with the
compression fitting on the inlet to the gas valve. Once the
gas inlet pipe is correctly engaged, the boiler module can
be finally secured to the wall plate at the left-hand bracket
using the M10 nut and bolt supplied. Tighten the
compression fittings to provide a gas tight seal. A
soundness check on these joints must be carried out.
10.3 Connection of Boiler(s) to the Flue System
Dependent on boiler installation a number of flue options
are available refer to Figures 6.1.
In all instances, the flue
must be obtained from Hamworthy or in the case of
connection to an open flue system, the ducts up to the
chimney must be obtained from Hamworthy.
The maximum allowable length of the flue must be
determined in accordance with
section 6.4 . It is also
important, for service requirements, that the flue system is
fully self-supporting and that prior to commissioning a
check has been made to ensure that the pipe is clear and
free from obstruction.
10.3.1 Connection of Through Wall Horizontal
Balanced Flue Terminal – 80/125mm.
The flue terminal should be cut to length as detailed in
Figure 10.3.1 Wall Mounted option or Figure 10.3.1.1
Frame Mounted option. Check all measurements before
cutting and
take care not to damage the inner tube
when cutting the outer tube.
Note: Deburr both tube ends and ensure that the cuts are
square. Failure to carry out this operation carefully may
result in damage to the flue seals when assembling the
flue system.
From the outside of the building, offer the outer wall sealing
plate up to the cut hole and position it such that there is a
2° slope from the terminal to the boiler connection to allow
any condensate to run back to the boiler. Mark the four
securing holes, drill and plug the holes and secure the wall
plate. From the inside of the building, offer the inner wall
sealing plate up to the cut hole and position it such that
there is a 2° slope from the terminal to the boiler
connection to allow any condensate to run back to the
boiler. Check the position of the wall plate using the flue

support cradle located on the 2 – M6 studs on the wall
frame. Mark the four securing holes, drill and plug the
holes. Fit the flue terminal from the inside of the building
ensuring the correct position of the terminal discharge –
see Figure 10.3.1 or Figure 10.3.1.1 and fit the inner wall
sealing plate over the flue, securing it to the wall.
Fit the flue support cradle over the end of the flue pipe,
then fit the flue concentric adaptor to the rear of the flue
protruding into the boiler. Ensure that the orientation of the
terminal is correct at the terminal outlet and that the
concentric adaptor is fully engaged onto the flue.
