To ensure correct operation of the appliance and avoid invalidating the guarantee, observe the following
precautions:
1.
Heating circuit
1.1.
new system
Before proceeding with installation of the boiler, the system must be cleaned and ushed out thoroughly
to eliminate residual thread-cutting swarf, solder and solvents if any, using suitable proprietary products.
To avoid damaging metal, plastic and rubber parts, use only neutral cleaners, i.e. non-acid and non
alkaline. The recommended products for cleaning are:
SENTINEL X300 or X400 and FERNOX heating circuit restore. To use this product proceeding strictly
in accordance with the maker's directions.

Before proceeding with installation of the boiler, the system must be cleaned and ushed out to remove
sludge and contaminants, using suitable proprietary products as described in section 1.1.
To avoid damaging metal, plastic and rubber parts, use only neutral cleaners, i.e. non-acid and non-
alkaline such us SENTINEL X100 and FERNOX heating circuit protective. To use this product proceeding
strictly in accordance with the maker's directions.
Remember that the presence of foreign matter in the heating system can adversely affect the operation
of the boiler (e.g. overheating and noisy operation of the heat exchanger).
Failure to observe the above will render the guarantee null and
10. BOILER INSTALLATION AND DIMENSIONS
Install the boiler in a position that ensures easy maintenance. You must be able to fully open the front access
door and have adequate access to the rear of the boiler.
If possible, install the boiler on a raised base of 200 mm in height to facilitate drainage of ue condensate.
When calculating the weight of the boiler on the oor, bear in mind the weight of the water in the heat exchanger
(see table 1).
Adjust the levelling feet to compensate for any unevenness in the oor.
Install the necessary utility connections starting from the water and gas connections on the rear of the boiler
(see table 1 for tting type and size).
The following steps are strongly recommended:
• Install two shut-off valves, one on the heating circuit delivery pipe (MR) and the other on the return pipe
(RR) so that you can service the boiler without having to drain the entire heating system.
• Use a metal pipe to connect the boiler's gas connection to the gas supply point, and t a (mandatory) shut-
off valve upstream from the boiler.
• Fit three-part joints in the water and gas connections to and from the boiler to separate it mechanically
from utility supplies.
• Fit a water separator (header).
• Install an automatic water lling system to keep the heating circuit full.
These appliances do not have any circulation pump, expansion tank or safety valve. These devices must
therefore be provided elsewhere in the system, and must be sized to suit the system's thermal capacity.
Connect the condensate drain using plastic pipe to sewer, ensuring an adequate slope. Fit condensate treatment
if sewer not plastic. To drain the boiler, use the drain tap at the rear.
N.B.: Take special care when lling the heating system. In particular, open any thermostat valves in the system,
ensure the water enters slowly in order to prevent the formation of air inside the primary circuit until operating
pressure is reached. Lastly, vent any radiators in the system. BAXI declines all liability for damage deriving from
the presence of air bubbles in the primary exchanger due to the incorrect or imprecise observance of the above.
