INSTRUCTIONS FOR FITTERS
13. TEMPLATE FOR FIXING THE BOILER TO THE WALL
After deciding the exact location of the boiler, fix the template to the wall.
Connect the system to the gas and water inlets present on the lower bar of the template.
Fit two G3/4 taps (flow and return) on the central heating circuit; these taps make it possible to carry out important opera-
tions on the system without draining it completely.
If you are either installing the boiler on an existing system or replacing one, as well as the above, fit a settling tank under the
boiler on the system return line in order to collect any deposits and scale circulating in the system after flushing.
The boiler has to be directly connected to an efficient chimney which unloads at the outdoor the products of combustion. The
connection section between boiler and flue must be at least the same as the connection boiler section. The chimney always
has to be under good conditions and does not have to have openings or cracks that can determine dispersions of draught.
