  USE AND MAINTENANCE 

INSTRUCTIONS

2.1  CLEANING AND MAINTENANCE.

Attention: 

to preserve the boiler's integrity 

and keep the safety features, performance and 

reliability, 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 “an-

nual check and maintenance of the appliance”, 

in compliance with national, regional, or local 

standards in force. Annual maintenance is es-

sential to validate the conventional warranty of 

Immergas. We recommend stipulating a yearly 

cleaning and maintenance contract with profes-

sionally qualified personnel.

2.2  GENERAL WARNINGS.

Never expose the wall-mounted boiler to direct 

vapours from cooking hobs.

Use of the boiler by unskilled persons or children 

is strictly prohibited.

Do not touch the flue gas exhaust terminal (if pre-

sent) due to the high temperatures it can reach;

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.
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 opera-

tions ensure that a qualified technician checks 

efficiency 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.
• 

Attenzione:

 the use of components involving 

use of electrical power requires some funda-

mental rules to be observed:

- do not touch the appliance with wet or moist 

parts of the body; do not touch when barefoot.

- never pull electrical cables or leave the appli-

ance exposed to weathering (rain, sunlight, 

etc.);

-  the appliance power cable must not be replaced 

by the user;

- in the event of damage to the cable, switch off 

the appliance and contact exclusively qualified 

staff for replacement;

- if the appliance is not to be used for a certain 

period, disconnect the main power switch 

upstream of the appliance.
