Instruction manual

SAFETY:
All relevant safety precautions must be undertaken.
Protective clothing, footwear, gloves and safety
goggles must be worn as appropriate.
PIPEWORK POSITIONS:
A - Flow 22mm Ø copper.
B - Return 22mm Ø copper.
C - Primary drain hose connection.
D - Condensate outlet 21.5mm Ø.
E - Flue outlet.
NOTE: For servicing purposes, keep condensate
and pressure relief discharge pipes away from
components and pipework connections.
IMPORTANT: The flue and pipework
openings are covered with tabbed blanks.
Remove carefully as necessary.
FLUE OPENING:
 Follow the diagram opposite to mark the
centre of the flue (1, & 2) for rear opening,
(2 & 3) for side opening or
(1 & 4) for top opening.
** IMPORTANT: for horizontal flues, increase
this height by 52mm for every 1000mm of
horizontal length that the flue opening is
away from the boiler.
NOTE: all horizontal flue sections must rise away
from the boiler by 52mm per metre to ensure that
condensate flows back into the boiler for safe
discharge via the condensate waste pipe.
 Make an opening (F, G or H) through the wall
using a core drill or similar at a size relative to
the wall thickness as shown below:
125mm Ø flue:
Wall thickness Flue hole size
150 - 240mm Ø155mm
240 - 330mm Ø160mm
330 - 420mm Ø165mm
420 - 500mm Ø170mm
 Use the wall mounting template
(supplied in the accessories box), to
check that the required clearances are
available around the proposed boiler
location. If the clearances are available
then secure the template to the wall,
making sure that the template is level,
and then mark the fixing points and flue
exit point onto the wall.
 If the flue is exiting to the left or right of
the boiler then the centre line of the flue
will need to be raised by 52mm per
horizontal metre distance from the boiler
(a 3° rise from the boiler).
CAUTION: Ensure there are no pipes,
electrical cables, damp proof courses or other
hazards before drilling.
