Boiler Location, Flue And Ventilation - Saunier Duval 47-920-36 Instructions For Use Installation And Servicing

6.1 Boiler Location
The recommended clearances are shown in diagram 6.1.
Note: The boiler must be mounted on a flat wall which is
sufficiently robust to take its weight when full. If in doubt, expert
advice should be obtained.
The minimum acceptable spacings from the terminal to
obstructions and ventilation openings are shown in diagram
6.2. For Ireland the minimum distances for the flue terminal
positionning must be those detailed in I.S.813 "Domestic Gas
Installations".
The boiler must be installed so that the terminal is exposed to
the external air.
6.2 Terminal guard, see diagram 6.3.
A terminal guard is required if persons could come into contact
with the terminal or the terminal could be subject to damage.
If a terminal guard is required, it must be positioned to provide
a minimum of 50mm clearance from any part of the terminal
and to be central over the terminal.
A suitable terminal guard type K3 can be supplied by:
