2.4.3 Connecting the gas supply
•
Before starting any work on the gas supply, turn off the main
isolation valve.
•
Remove the dust cap from the gas connection
at the
bottom of the boiler.
•
Connect the gas supply to the 22 mm Ø connection (copper
tail supplied).
•
Make sure there is no dirt in the gas pipe. Blow through
the pipe before installation or tap well to clear.
•
Make sure that there is sufficient gas pressure available
(at full load > 17 mbar).
•
Preferably install a gas filter in the gas pipe to protect the
boiler.
•
The gas supply must be connected, tested for soundness
and purged by a qualified Engineer and in accordance
with BS6891.
2.5 Flue terminal and air supply connections
The Remeha Avanta 18v is only suitable for room sealed
operation with a standard concentric connection 60/100 mm Ø
or the optional 80/125 mm Ø connection.
Detailed recommendations for air supply and flue terminals are
given in BS 5440.
2.5.1 Flue terminal positions
The flue terminal must be located with care to ensure that the
products of combustion are dispersed properly in all weather
conditions and cause minimum nuisance to the building user
or any adjacent buildings. If the terminal is positioned less
than 2 m above the ground, balcony, or flat roof where access
by persons is possible a suitable guard must be employed.
The boiler will produce a water vapour plume during normal
operation.
Positions for the Remeha Avanta
18v are shown in the figure
