2. Balanced Flue Boilers
The Firebird boiler may be set for Room-sealed balanced flue operation using
a Firebird balanced flue kit and then does not draw combustion air from
inside the room. It is drawn from outside direct to burner by airpipe
supplied with boiler. Flue gases are expelled in the same way. However, if
the boiler is installed in a compartment or small room, some ventilation air
is necessary to maintain acceptable temperature in boiler area
4-F Domestic Heating & Hot Water Systems
HVCA Codes of Practice and BS 5449: Part 1 “Forced Circulation Hot Water
Systems” should be adhered to when installing the boiler. Refer also to
Regulations and Standards listed on page 14.
Electrical Supply
The boiler and controls require 230V 1 phase 50Hz electric supply
with a 5amp fuse.
THIS APPLIANCE MUST BE EARTHED.
A qualified electrician must carry out all electric wiring in accordance with
current I.E.E Regulations and any local regulations which may apply.
The mains electrical supply must be taken from a double pole isolating switch
with a 5amp fuse, positioned somewhere close to the boiler. Heat resisting
cable must be used which can be routed into the boiler through the access
provided on either side of the base.
Ancillary controls may be provided for with terminal connections
in the control panel.
Balanced flue boiler in room (eg. kitchen) does not require individual ventilation.
