FLUE / AIR DUCT INSTALLATION
The boiler is delivered assembled and protected by a cardboard sleeve and
fittings and fixed on a wooden base. This allows the boiler to be handled by a
forklift.
The packaged boiler will pass through a 800mm wide opening and unpacked
boiler through a 700mm wide opening.
To unpack the boiler:
-
Carefully remove the straps, and lift off the cardboard sleeve.
-
Remove the protective cardboard fittings.
-
Safely dispose of all packing materials.

PACKAGING REMOVAL / REMOVAL FROM PALLET / LOCATING & LEVELLING
FLUE
A flue sampling point should be provided in the flue
system.
When fitting the flue to the flue socket take care not to
disturb the lip seal which must be present.
The flue should be supported in such a way as not to
place a load on the flue socket.
IMPORTANT NOTE.
Unless the flue is manufactured from aluminium the
condensate from the flue must be collected and drained
before entering the sump of the boiler. See page 5 for
details on flue system design.
AIR DUCT
Combustion air can be drawn directly from the boiler room
using the high level air inlet kit provided or ducted in from
outside (see ventilation page 8).
To draw air direct from outside use any proprietary 110mm
soil/drain pipe. The air duct should be terminated with a
suitable fixed grille to prevent entry of vermin. This
terminal should be positioned as such to avoid blockages
or entry of water.
Where ducting the air from outside is not practical it can
be drawn from the boiler room by assembling the air inlet
pipework as follows into the configuration,shown in fig. 1.
1.
Fit the 93º elbow into the boiler air inlet pipe.
2.
Fit the 112.5º bend into the 93º elbow.
3.
Fit the 110 dia. tube, 590mm long, into the 112.5º
bend.
To remove boiler from base:
1.
Remove the 3 front screws on both sides
leaving the 2 rear screws in place.
2.
Rotate bottom battens outwards allowing
the front of the base to rest on the floor.
3.
Remove 4 screws and retaining brackets.
4.
Slide the boiler off the base.
At final location, adjust height of feet as
necessary to level the boiler.
4.
Fit the air inlet grille to 100 dia. tube and fix the 3 off self-
tapping screws provided.
5.
Using the existing screws holding the upper back panel
to the boiler, fit the support bracket assembly and re-
tighten the screws.
6.
With the air inlet pipe assembly in position, retain it with
the pipe clamp, fixed with 2 off M5 screws provided.
With this kit fitted the maximum straight flue length available and
maximum pressure available at the base of the flue to overcome
flue resistance will change, refer to the appropriate table on
page 5.
