Page 19: Instructions For The Fitter
3. 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. -
Page 20: Positioning The Boiler
3.2.3. Positioning the boiler Each boiler is supplied with a paper template (pic. 6), within its packa- ging, 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. -
Page 21: Boiler Room Ventilation
3.2.5. Boiler room ventilation The boiler has sealed combustion chamber. Combustion air is not drawn from boiler room therefore specific recommendations need not to be applied concerning the boiler room or openings and ventilation provided to the boiler room. It is mandatory to install the boiler in an adequate room following laws and standards applicable in the country of installation, which are considered as fully transcribed in this manual. -
Page 22: Air/Flue Gas System Duct Configuration
3.2.6.1. Air/flue gas system duct configuration Type B23 Boiler intended for connection to an existing flue system external to the boiler room. Combustion air is taken directly from the boiler room itself while flue gas is conveyed to the outside. The boiler is not to be fitted by anti-wind gust device;... -

The tower is designed with two pre-arranged openings directly accessing air and flue gas ducts (pic. 15). Remove cap A from the pre-arranged openings on the tower, before starting combustion checking procedure (pic. 14). In order to verify combustion performance the following measurements must be implemented: - assess combustion air from no. -
Page 26: Gas Main Connection
3.2.8. Gas main connection Gas supply pipe cross-section must be equal or greater than boiler gas pipe. Cross-section gas pipe size calculation depends on its length, layout pattern, gas flow rate. Gas pipe size is to be dimensioned accordingly. Comply with installation standards enforced in the installation country which are considered as fully transcribed in this booklet. Remember that before operating an indoor gas distribution system and before connecting it to a meter, it must be checked for leaks. -
Page 27: Power Main Connection
CONDENSATE DRAIN Comply with condensate drain laws and standards applicable in the country of installation and which are considered herein integrally tran- scribed. When the law is not stating differently, the condensate produced by combustion, is to be routed (via the condensate drain S in pic. 3) through a discharge system connected to the domestic sewer, which due to its basicity, counteracts flue gas condensate acidity. -
