Boiler Installation Information

4.1 introduction
The boiler is supplied already fully
assembled with the flue terminal guard
supplied loose inside the boiler.
4.2 Boiler Location
1. The External Combi boiler must
stand on a solid, level surface
capable of supporting the weight of
the boiler when full of water, e.g. a
prepared concrete standing, paving
slabs bedded down on sand /
cement, or similar.
2. The Module can be installed either
against the building or ‘free standing’
some distance away from the
building.
3. The Module must be positioned
such that the required clearances
from the low level flue outlet, as
shown in Figure 9-1, are achieved.
4. Adequate clearance must be left
around the boiler for servicing. In
particular, a minimum clearance of
600mm above the boiler for removal
of the top panel and 600mm at
each end allow for access to the
burner and condensate trap.
4.3 Preparation for installation
1. Carefully remove the packaging
from the boiler and remove it from
the transit pallet.
2. Remove the case top panel and
also the front and rear panels, as
required.
3. The flue may exit the boiler from
the left, right or rear of the casing.
Carefully press out the pre-cut
section on the side or end casing
panel to provide the opening in the
required position for the flue to pass
through the casing.
Fit the cover panel (with the round
flue exit hole) over the square flue
opening in the casing. Fit the circular
rubber sealing grommet provided
into the hole in the cover panel
before fitting the flue terminal section.
4. Slacken the wing nuts holding the
flue elbow and rotate the elbow to
the required direction for the flue to
exit the casing.
5. Push the end of the flue terminal
section with the red seal through
the seal in the casing. The terminal
has been factory lubricated. Take
care not to dislodge or damage the
red seals.
6. Carefully insert the terminal into
the flue elbow until the bend of the
terminal contacts the outer casing,
then, pull the terminal forward
approximately 25mm and rotate the
bend so that the outlet is horizontal.
Rear Exit - The flue must discharge
away from the building.
Side Exit - The flue should
discharge towards the rear of
the casing to prevent flue gases
reentering the boiler casing through
the air inlet vents on the casing
front door.
The flue terminal must be fitted
horizontally to prevent dripping from
the end of the terminal.
7. Tighten the wing nuts holding the flue
elbow and fit the stainless steel flue
guard using the two screws provided.
8. The top panel of the casing has
been designed so that it may be
fitted to create a slight slope away
from the side positioned against the
wall. To tilt the top panel, loosen
the four top panel casing screws,
one at each corner and push down
on the side furthest from the wall.
Tighten the screws. See Figure 4-1.
4.4 installing the Boiler
1. If the boiler is to be fitted against
the wall, prepare the wall to accept
the heating system pipework. To
mark the wall for drilling, refer to
Figure
2-1 for the positions of the
pipework openings in the enclosure
sides.
Pipework should be insulated where
it passes through the wall into the
boiler enclosure.
2. A painted steel wall flashing strip
is supplied with the boiler to cover
the gap between the wall and the
boiler casing. It should be secured
to the wall leaving a gap of 30mm
between the bottom edge and
the top of the casing top panel, to
allow removal of the top panel for
servicing.
3. If the boiler is to be installed ‘free
standing’ (that is, away from a wall)
and the pipework run underground,
push out the ‘knock-outs’ to open
the required pipe openings in the
base of the boiler enclosure.
Using a sharp knife, cut through
the polystyrene in the base, around
the edge of the holes, to allow the
flow and return pipes to enter the
enclosure.
A spare blanking plate with a 112mm
diameter hole is supplied with the
Outdoor Vortex Combi boilers. This
is intended to provide an opening
into the boiler if a 110mm soil pipe is
used as a pipe duct through the wall.
