2.13 CLEANING THE CASE.
Use damp cloths and neutral detergent to clean the boiler casing.
Never use abrasive or powder detergents.
2.14 DECOMMISSIONING.
In the event of permanent shutdown of the boiler, contact profes-
sional staff for the procedures and ensure that the electrical, water
and gas supply lines are shut off and disconnected.
2.15 GAS SYSTEM NOT USED FOR PERIODS OVER 12
MONTHS.
Th e current regulation provides that gas systems not used for
over 12 months must be checked prior to being used again, as per
regulations in force, by professionally qualified staff.
If the inspection is successful, the boiler can be recommissioned
according to the instructions specified in point 3 herein.
2.11 STORAGE TANK DRAINING.
To drain the storage tank, use the special draining valve (Fig. 34).
N.B.:
before performing this operation, close the boil-
er cold water inlet valve and open any DHW system
hot water valve in order to let air into the storage tank.
2.12 ANTIFREEZE PROTECTION.
Th e boiler has an antifreeze function that switches the burner on
automatically when the temperature falls below 4°C (standard
protection to minimum temperature of 0°C). All information
relative to the antifreeze protection is stated in (Par. 1.4). In order
to guarantee the integrity of the appliance and the domestic hot
water heating system in zones where the temperature falls below
zero, we recommend the central heating system is protected using
anti-freeze liquid and installation of the Immergas Antifreeze Kit
in the boiler. In the case of prolonged inactivity (second case), we
also recommend that:
- the electric power supply is disconnected;
- the heating circuit and boiler domestic water circuit must be
drained. In systems that are drained frequently, filling must be
carried out with suitably treated water to eliminate hardness that
can cause lime-scale.
