Read Chapter 3 - Boiler Location and decide upon the position of the boiler.
Installation of the boiler is straightforward but consideration must be given to access to allow flue
and air pipes to be pushed through walls and ceilings. The order in which the components are
installed will depend upon particular site conditions, but in general it will be easiest and most
accurate to install the boiler and then build up the flue outlet and air inlet pipes to the terminal - this
is the sequence described.
4.1
WALL MOUNTING BRACKET
a
Place the bracket on the
wall horizontally with the
pre-drilled holes at the
bottom and position as
dictated by the template
supplied within the boiler
packaging.
b
Drill through the centre
hole of the bracket, plug
the hole and fix in position.
c
Using a spirit level make
sure
completely level and mark
the position of the other
screw holes.
d
Remove the bracket and
drill
the
positions
these holes.
e
Screw the bracket to the
wall using screws of an
appropriate size for the wall type (No. 12 x 2 inch wood screws normally suffice).
4.2
MOUNTING THE BOILER (after system cleaning and testing)
a
Lift and locate the boiler in the studs protruding from the wall bracket.
b
Fix the boiler on the bracket studs using the nuts and the washers supplied.
c
Make the gas, flow, return and condensate connections to the system. Check all
joints for tightness.
4.3
ASSEMBLY PRACTICE
Remove all plastic debris and burrs when installing air intake piping. Plastic filings caused
by cutting muPVC pipe must not be allowed to be drawn into the combustion air blower.
Prevent dust entering the air intake when cutting on building sites. Blower failure which is
determined to be caused by plastic filings or other debris will not be covered by guarantee.
4.4
INSTALLING FLUE AND AIR PIPES
IMPORTANT - When installing the boiler on an existing system a new flue and air
intake system MUST also be installed. You must NOT re-use existing flue or air
pipework components.
NB:
When installing the boiler, consider:
Flue Spigot Assembly
The flue spigot (50mm muPVC) is inside the accessory bag.
Put the flue spigot assembled with the test plug on the cabinet frame and secure
it by fastening the four M6 screws & bolts and the gasket with the internal flue
pipe flange.
Remember the flue pipe must slope downwards back towards the boiler and this
is best achieved using 92.5
