Ventilation
All rooms require a window or equivalent (e.g. a door) which can be
opened. Some rooms require a permanent vent in addition to a win-
dow (see below).
This unit must not be used in a room which is less than 5m

. The fol-
lowing table details the requirements based on the kitchen volume
(L x W x H) in m

.
The above requirements also allow use of a gas oven and grill but if
there are any other fuel burning appliances in the same room, consult
the relevant British Standard (BS5440) or GAS SAFE document.
Sealing the gas connection
The gas inlet fitting for these models is a ½” male threaded conic gas
type, complying with ISO 7-1 standards. Please ensure that the con-
nection is made using rigid (15mm copper) pipe (see page 18). When
making the connection, it is important to place the fibre washer (A) in
betweem the inlet pipe (C) and the elbow (B) to ensure a tight seal.
