• The fi replace recess or opening is
suitably constructed and conforms to
all applicable building regulations and
can accommodate the stove along with

non-closable dedicated air supply within
the room which must conform to all
applicable building regulations. The

a maximum output of 11.7 kW when
burning Ancit and therefore this fi gure
should be used for any air supply
calculations.
