USE AND MAINTENANCE
INSTRUCTIONS
2.1 CLEANING AND MAINTENANCE.
Warning:
to preserve the boiler’s integrity and
keep the safety features, performance and relia-
bility, which distinguish it, unchanged over time,
you must at least execute maintenance operations
on a yearly basis in compliance with what is stated
in the relative point at “annual check and main-
tenance of the appliance”. Annual maintenance
is essential to validate the conventional warranty
of Immergas. We recommend stipulating a yearly
cleaning and maintenance contract with your
zone Immergas Authorised After-sales Service.
2.2 AERATION AND VENTILATION OF
THE INSTALLATION ROOMS.
Consult the "Aeration and ventilation of instal-
lation rooms" chapter contained herein and, in
any case, always refer to the provisions set forth
by standards and all legislation in force.
2.3 GENERAL WARNINGS.
Use of the boiler by unskilled persons or children
is strictly prohibited.
For safety purposes, check that the concentric
air intake/flue exhaust terminal (if fitted), is
not blocked.
If temporary shutdown of the boiler is required,
proceed as follows:
a) drain the heating system if anti-freeze is not
used;
b) shut-off all electrical, water and gas supplies.
N.B.:
in the case of maintenance interventions
on the boiler that lead to the closure of one or
both system cut-off cocks, the boiler must be off.
In the case of work or maintenance to structures
located in the vicinity of ducting or devices for
flue extraction and relative accessories, switch off
the appliance and on completion of operations
ensure that a qualified technician checks efficien-
cy of the ducting or other devices.
Never clean the appliance or connected parts
with easily flammable substances.
Never leave containers or flammable substances
in the same environment as the appliance.
