scale, neutral pH stabilizers and, in low-temperature systems, specific biocides for
use in heating systems.
Recommended chemical conditioners:
SENTINEL X100 and SENTINEL X200
FERNOX F1 and FERNOX F3
The unit is equipped with a frost protection system that activates the boiler in hea-
ting mode when the system delivery water temperature falls below 6°C. The device
is not active if the power and/or gas supply to the unit is turned off. If necessary,
for system protection use a suitable antifreeze liquid that meets the same require-
ments as set out above and provided for by Standard UNI 8065.
In the presence of adequate chemical/physical system and feed water treatments
and related high cyclicity controls able to ensure the required parameters, for indu-
strial process applications the product can be installed in open-vessel systems with
vessel hydrostatic height able to ensure compliance with the minimum operating
pressure indicated in the product technical specifications.
The presence of deposits on the boiler exchange surfaces due to non-com-
pliance with the above requirements will involve non-recognition of the war-
ranty.
Frost protection kit for outdoor installation (optional - 013022X0)
In case of installation outdoors in a partially protected place, for temperatures below -5°C and down to -15°C, the boiler
must be fitted with the special frost protection kit. For proper installation, please refer to the instructions in the kit.
2.4 Gas connection
B
Before making the connection, ensure that the unit is arranged for operation
with the type of fuel available.
The gas must be connected to the corresponding union
(see fig. 57)
in con-
formity with current regulations, with a rigid metal pipe or with a continuous
flexible s/steel tube, installing a gas cock between the system and boiler.
Make sure that all the gas connections are tight. Otherwise there may be a
risk of fire, explosion or suffocation.
2.5 Electrical connections
IMPORTANT
B
BEFORE CARRYING OUT ANY OPERATION THAT REQUIRES REMOVING
THE CASING, DISCONNECT THE BOILER FROM THE ELECTRIC MAINS
WITH THE MAIN SWITCH.
NEVER TOUCH THE ELECTRICAL COMPONENTS OR CONTACTS WITH THE
MAIN SWITCH TURNED ON! DANGER OF ELECTRIC SHOCK WITH RISK OF
INJURY OR DEATH!
B
The unit must be connected to an efficient grounding system in accordance with ap-
plicable safety regulations. Have the efficiency and suitability of the grounding sy-
stem checked by professionally qualified personnel; the Manufacturer declines any
liability for damage caused by failure to earth the system.
