sturdy cardboard box on a wooden
pallet. Take the boiler out of the
box and check that it is intact. All
the packaging materials can be
recycled and should be sent to
specific waste management sites.

resulting from failure to follow
this rule.
Inside the box is a bag containing
the handbook for the installation,
use and maintenance.
3.2.2 Choosing where to install
the boiler
Rules to bear in mind when choo-
sing the place:
- It is advisable to leave at least 50
cm on either side of the boiler for
easy access for maintenance.
- Do not install the boiler in wet or
dusty areas.
- The boiler must not be accessi-
ble to animals, children or anyone

3.2.3 Installing the boiler
Before connecting the boiler to
the tap water and heating system
pipes, carefully clean the pipes to
remove all traces of metal resul-
ting from processing and welding
operations as well as any oil and
grease which could damage the
boiler or jeopardize its operation.
N.B. Do not use solvents which
could damage the components.
The Manufacturer declines all lia-
bility for damage or injury resulting
from failure to follow the above
rules.
Proceed as follows to install the
boiler:
- Unscrew the four screws secu-
ring the brackets of the boiler to
the pallet (pic. 3).
- Pass belts or cables underneath
the boiler and around the legs,
lift it off the pallet and place it in
position on the ground. Attention:
when lifting the boiler from the
pallet, hold it to prevent it from
turning over (pic. 4).
- If the boiler needs to be stabili-
sed, insert shims between the floor
and the boiler legs.
- Connect the boiler to the flow and
return pipes.
- Remember that the plumbing
system must be fitted with all
the necessary safety and control
systems specified by law (safety
valve, water pressure switch, hot
water discharge valve, pressure

- Connect the boiler to the chim-
ney.
- If there is an ambient thermostat,
heating pump or hot water pres-
