Instructions for the installer
3.2 Choosing where to install the boiler
The following must be taken into account when choosing where to install the boiler:
• indications contained in paragraph
Air intake and flue gas venting system
on page
44
and its sub-paragraphs.
• check the wall for sturdiness, avoiding weak areas.
• do not install the boiler over appliances which may affect boiler operation (e.g. cookers, which produce steam and grease, washing
machines etc.).
3.3 Positioning the boiler
Each boiler is supplied with a paper template, found inside the packaging (see Fig. 6 Paper template).
The template allows you to ensure that the pipes connected to the CH system, the DHW system and the gas mains, and the air intake/flue gas
venting ducts are all laid out correctly during the realisation of the water system and before installation of the boiler.
This template is made of heavy-duty paper and must be fixed, with the help of a level, onto the wall where the boiler is to be mounted.
The template provides all the indications required to drill the boiler mounting holes to the wall, procedure which is done using two screws
and wall blocks.
The lower area of the template shows where to mark the exact point at which the couplings are to be positioned for boiler connection to the
gas supply pipe, cold water mains supply pipe, hot water outlet, CH flow and return pipes.
The upper area of the template shows where air intake and flue gas ducts are to be positioned.
DANGER
Since the temperature of the walls on which the boiler is mounted and external temperature of coaxial air/flue gas system do not
exceed 60°C, no minimum distance from flammable walls is to be accounted for.
For boilers with split air intake and flue gas venting ducts, in the case of proximity with flammable walls and passages through
walls, apply insulating material between the wall and the flue gas venting duct.
