1 The Outdoor Module 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 Fig.
11, are achieved.
4 Adequate clearance must be left around the Module for
servicing. In particular, a minimum clearance of 600 mm
above the Module for removal of the top panel and 600 mm
at the opposite end to the flue outlet for access to the burner.

5 The flue terminal must be a minimum distance of 1.8 m
from an oil storage tank.
The flue terminal should be positioned so as to avoid
products of combustion accumulating in stagnant pockets
around the building or entering into buildings.

and Building Regulations.
Notes:
1 An opening means an
openable element, such as
an openable window, or a
permanent opening such as a
permanently open air vent.
2 Notwithstanding the dimen-
sions given, a terminal
should be at least 300 mm
from combustible material,
e.g. a window frame.
3 A way of providing protec-
tion of combustible material
would be to fit a heat shield
at least 750 mm wide.
