1. instructions prior to installation

This boiler is designed to heat water at a lower than boiling temperature at atmospheric pressure. The boiler
must be connected to a central heating system and/or to a domestic hot water supply system in compliance
with its performances and output power.
The boiler must be installed by a Qualified Service Engineer and ensure the following operations are carried
out:
a) Check that the boiler is fit for operation with the type of gas available. For more details see the notice on the
packaging and the label on the appliance itself.
b) Careful checking that the flue terminal draft is appropriate; that the terminal is not obstructed and that no
other appliance exhaust gases are expelled through the same flue duct, unless the flue is especially desi-
gned to collect the exhaust gas coming from more than one appliance, in conformity with the standards and
regulations in force.
c) Careful checking that, in case the flue has been connected to pre-existing flue ducts, thorough cleaning
has been carried out in that residual combustion products may come off during operation of the boiler and
obstruct the flue duct.
d) To ensure correct operation of the appliance and avoid invalidating the warranty, observe the following
precautions:
1. Heating circuit
1.1. New system
Before proceeding with installation of the boiler, the system must be cleaned and flushed 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. The use of this product must be strictly
in accordance with the maker's directions. Finally the system must be dosed with a suitable inhibitor at
1% system volume.
1.2. Existing system
Before proceeding with installation of the boiler, the system must be cleaned and flushed 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 proceed
strictly in accordance with the maker's directions. Dose with inhibitor.
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 warranty null and

2. instructions prior to coMMissioning
