11.2 GENERAL PREPARATION.
11.2.1 The following description covers one method of
installation. Extra space may be required for installation if
service connections are made in a different way.
Compression fittings may be used on all water connections to
allow for the fitting of the appliance and servicing.
Pipework must be routed so as not to obstruct access to the
circulating pump, diverting valve, gas valve, water to water heat
exchanger or heat bank.
Removable sections are provided in the cabinet top panel to
facilitate vertical pipe connections and flue system,if required.
Removable sections are provided in the side panels to
accommodate a side flue system.
11.2.2 Check the appliance carton contains :
Appliance.
Installer’s Instruction Pack.
User’s Information Pack.
Hardware Pack with flue restrictor rings.
11.2.3 Carefully remove the appliance from the cardboard
package and plinth.
Check the position chosen for the appliance is in accordance with
the instructions given in Sections 4 and 5. Also refer to Fig. 2.
Do not place the appliance in its final position at this stage.
11.2.4 For all flue options from the dimensions given in Fig. 13
carefully mark out:
(i) the wall with the centre-lines for the Rear Flue centre point
position.
(ii) the floor with the base outline of the appliance.
Having decided upon the most suitable flue option for the
installation, the position of the hole for the flue must now be
marked on the wall/walls.
FLUE OPTION 1. See Fig. 12 1.
The location of the centre point position for the Rear Flue is
obtained from the flue centre-lines previously marked.
This is the Rear Flue centre point position. See Fig. 13.
FLUE OPTION 2. See Fig. 12. 2.
Draw a horizont
al line from the Rear Flue centre point position in
the appropriate direction along the wall. Measure 94 mm from
the junction of the walls and make a short vertical line. Extend
the horizont
al line to intersect the vertical line and mark the
position.
This is the Side Flue centre point position. See Fig. 13.
FLUE OPTION 3. See Fig. 12. 3.
The location of the centre point position for the Rear Flue is
obtained from the flue centre-lines previously marked.
If the flue duct extends through other walls ensure it remains
horizontal.
This is the Rear Flue Extension centre point position. See Fig. 13.
FLUE OPTION 4. See Fig. 12. 4.
Draw a horizont
al line from the Rear Flue centre point position,
previously marked, in the appropriate direction along the
wall/walls.
If the flue system extends through other walls or the appliance is
not installed close to a wall, ensure it remains horizontal.
Measure 94 mm from the junction of the walls if the appliance is
installed against a wall and make a short vertical line.
If the appliance is NOT installed against a wall, measure the
distance from the junction of the walls, make a short vertical line
to suit the installation. Extend the horizontal line to intersect the
vertical line and mark the position.
This is the Side Flue Extension centre point position. See Fig. 13.
FLUE OPTION 5. See Fig. 12. 5.
Draw a horizont
al line from the Rear Flue centre point position,
previously marked, in the appropriate direction along the
wall/walls. Check that it remains horizontal.
If the flue system extends through other walls or the appliance is
not installed close to a wall, ensure it remains horizontal.
This is the Side Flue Extension centre point position. See Fig. 13.
FLUE OPTION 6. See Fig. 12. 6.
Draw a vertical line upwards from the Rear Flue centre point
position previously marked. Extend the line, approximately 250
mm, above the position required for the centre-line of the
horizontal flue duct. See Fig. 13.
Mark the position on the vertical line to coincide with the centre-
line position of the horizontal duct.
This is the Rear Flue Upwards Extension centre point
position. See Fig. 13.
FLUE OPTION 7. See Fig. 12. 7.
Follow the procedure as described in Flue Option 5 ensure the
flue system remains horizontal.
This is the Side Flue Extension centre point position. See Fig. 13.
FLUE OPTION 8. See Fig. 12. 8.
Follow the procedure as described in Flue Option 6 ensure the
flue system remains vertical and horizontal.
This is the Rear Flue Upwards Extension centre point
position. See Fig. 13.
FLUE OPTION 9. See Fig. 12. 9.
NOTE: A flue adaptor is required for these flue options.
Refer to Flue Options: 2, 4, 5, 6, 7 and 8.
For installations that require a straight section of flue duct before
the first 90° flue bend, follow the procedure as described in the
appropriate Flue Option. Mark the flue centre point position.
Drill the flue hole/holes 120 mm diameter, ensure it is
horizont
al, through the wall/walls.
If the internal flue fitting kit is used the hole must be 150 mm
diameter.
11.2.5 FIXING THE APPLIANCE FOR ALL FLUE OPTIONS.
Gas and Water connections
Depending upon the site conditions it may be helpful to pre-
plumb the appliance before moving it into position. Fitting
unions or stub pipes to the appliance pipework should be done
at this stage. Refer to Section 3 and Fig. 3.
Pipework must be arranged to clear the flue system. See Section
5 and Fig. 5.
Before the appliance is connected to the central heating
system, thoroughly flush the heating system and the mains
cold water supply pipe.
IMPORTANT: Any proprietary cleanser must be flushed from
the system.
