Instructions for the fitter
3.1.
Installation standards
This is an II2H3P category boiler and must be installed in compliance with laws and standards enforced in the country of installation, which are
herein considered as entirely transcribed.
3.2.
Installation
Accessories and spare parts for installation and service procedures are to be supplied by the Manufacturer. Should non
original accessories and spare parts be employed, boiler proper performance is not guaranteed.
3.2.1. Packaging
Boiler is shipped in a sturdy cardboard box.
Remove boiler from cardboard box and check its integrity.
The packing materials can be recycled. Disposal of must be managed via appropriate waste collection sites.
Keep packaging out of reach of children, as it may be dangerous.
Manufacturer shall not be held responsible for harm to people and/or animals, and/or damage to property due to failure in following the above
mentioned instructions.
Packaging includes:
•
for model KRB two interception valves: one for gas and one for connection to the water heater, the latter fitted with the system loading tap;
• copper pipe kit for boiler connection to the gas mains, to the CH system (KC and KR) and DHW system (KC);
•
for model KRB two interception valves: one for gas and one for connection to the water heater, the latter fitted with the system loading tap;
• wall hanging bracket;
• a bag containing:
a) boiler installation, use and maintenance manual.
b) boiler wall mounting template (fig. 8).
c) two screws and wall plugs for fixing the metal plate to the wall.
3.2.2.
Choosing where to install the boiler
The following must be taken into account when choosing where to install the boiler:
• 3.2.6. “Air intake /flue gas discharge system” instructions and follozing paragraphs;
• check the wall for sturdiness, avoiding weak areas;
• do not hang the boiler above any equipment which may prejudice proper operation (steam and greasy vapor emitting kitchen appliances,
washing machines, etc.).
3.2.3.
Positioning the boiler
Each boiler is supplied with a paper template (fig. 10), within its packaging, allowing arrangement of CH pipe system, DHW pipe system, gas supply
pipe system and air intake/flue gas discharge system
before actually installing the boiler
.
The template is made of heavy-duty paper, it is to be affixed to the wall where the boiler is to be mounted using a carpenter’s level. It provides all
the indications required to drill the boiler fixing holes to the wall, procedure which is done using two screws and wall plugs.
The lower area of the template displays where to mark the exact point at which the couplings are to be positioned for boiler connection to the gas
supply pipe, water mains supply pipe, DHW flow pipe, CH flow and return pipes.
The upper area of the template displays where air intake and flue gas ducts are to be positioned.
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.
Boilers with split pipe flue system: in presence of flammable walls and flue gas ducts through such walls, ensure proper
insulation between wall and flue gas ducts.
