▪ The boiler can be installed outdoors in a partially protected
location. A partially protected location is a place where the boiler
is not exposed to the direct action and to the penetration of
atmospheric precipitation (rain, snow, hail,...).
The boiler can also be installed inside of an outside wall using the
appropriate in‑wall kit.
In case of outdoor installation, use the antifreeze kit
(DRANTIFREEZxx ) to prevent the piping and condensate trap
from freezing.
▪ Flammable fluids and materials must be stored at least 1 metre
away from the boiler.
▪ The wall on which the unit is mounted should be strong enough to
carry the unit's weight. Build a reinforcement if necessary.
▪ The following minimum clearances are required for servicing:
180 mm above the casing*, 200 mm below, and 10 mm at each
side. 500 mm at the front clearance may be realised by opening a
cupboard door. See
"Minimum installation clearances"
10].
▪ For easier use of control panel, it is recommended that boiler
bottom is 1500 mm from the floor, for easier part replacement side
clearances should be 50 mm where applicable. See
10].
▪ If the boiler is installed in a room or compartment, it does not
require a dedicated ventilation for combustion air. If however
installed in a room containing a bath or a shower, then particular
reference is drawn to the current I.E.E. Wiring Regulations, local
Building Regulations or any other local regulations currently in
service.
▪ The intake air must not include chemicals that may cause
corrosion, toxic gas formation and even risk of explosion.
▪ If the wall on which the unit is mounted, is flammable, a non-
flammable material must be placed between the wall and the unit
and also at all locations through where the flue piping passes.
