AIR REPLACEMENT PREPARATION
The Fireplace Ltd specifies that allowances must be made for air replacement vents to be located near the fireplace,
to aid combustion and reduce the incidence of back venting. Refer below for air vent sizing and suggested location.
Fig. 26 - Location points A,B,C,D are suggested combinations. A minimum of one pair of air vents is
recommended or one large vent, as per location point D. Allowance to be made for minimum 2 inlet ducts from outside
to internal vent location.
Note: DO NOT USE FIREPLACE CAVITY VENTILATION AS A METHOD OF AIR REPLACEMENT.
