The maximum FEL of fl ue in this confi guration is
25 metres.
The air inlet connection to the appliance must
be fi tted with a Debris Guard. Air is drawn from
the room or compartment in which the heater is
installed and therefore the room or compartment
must be ventilated. See Page 11.
The fl ue duct can discharge either vertically or hori-
zontally by selection of the correct fl ue terminal.
The fl ue pipe can be fi tted with 90 and 45 degree
bends as well as extensions.
Example:
A B system with air collected from the plant room
