7.6 Boiler gas connection
CAUTION
Before making the connection, check that the appliance is pre-configured for operating with the type of gas avail-
able.
The gas connection must be made to the relevant fitting (see “fig. 7 - dimensional data and connections" on page
24) in compliance with the regulation in force, with a rigid metal pipe or a flexible stainless steel hose pipe, with a
gas tap placed between the system and the boiler. Check that all the gas connections are tight. If not, there may be
a risk of fire, explosion or asphyxiation .
7.7 Boiler fume ducts
WARNING
THE BOILERS MUST BE INSTALLED IN ROOMS WHICH FULFIL THE BASIC AERATION REQUIREMENTS. IF NOT,
THERE IS A RISK OF ASPHYXIATION OR INTOXICATION.
READ THE INSTALLATION AND MAINTENANCE INSTRUCTIONS BEFORE INSTALLING THE APPLIANCE.
OBSERVE THE DESIGN INSTRUCTIONS AS WELL.
IF THERE ARE PRESSURES IN THE FUME DISCHARGE PIPES OVER 200 Pa, CLASS “H1” FLUES MUST BE USED.
7.7.1 Warnings
The appliance is a “type C” with a sealed chamber and forced draft; the air inlet and smoke outlet must, therefore, be connected to one of the evacuation/extraction
systems indicated below. Before installation, check and strictly comply with the relevant provisions. Also respect the provisions on the positioning of the wall and/or
roof terminals and the minimum distances from windows, walls, ventilation openings, etc.
In the case of installation with maximum resistance (coaxial or separate chimney), we recommend calibration [AUTO SETUP] to optimise boiler combus-
tion.
7.7.2 Connection with coaxial pipes
fig. 19 - Example of connection with coaxial pipes (
= Air /
= Fumes)
Install one of the following starter accessories on the device for the coaxial connection. Refer to the figure on the cover for the position of the holes on the wall. Any horizontal fume discharge sections
must be slightly inclined towards the boiler to prevent any condensation from flowing outwards and causing drips.
