6.4 GAS CONNECTION
NOTE: The appliance must be connected to gas with rigid or
semi-rigid tubing, from either the right or left hand side, or by
concealed connection (see below). The supply pipe to the fire
should be installed so that it is easy to remove the fire from the
opening during servicing. An isolation inlet elbow is fitted to the
burner assembly for isolation of the fire for servicing at a later
date.
If a concealed connection from within the fireplace is required
then, before the appliance is fitted into the fireplace, it will be
necessary to extend the supply line so that it will project through
the sealed opening situated at the back of the firebox to the
appliance inlet elbow.
6.4.1. CONCEALED CONNECTION
Remove the isolation elbow from the burner assembly. Fig 16.

Knock out at the required position using a hammer and
screwdriver to gently but firmly knock out the hole. Refer to Fig
17. Push in the hole the large grommet provided in the screw
pack. If necessary the grommet can be softened by placing it on
top of a kettle whilst it is boiling until supple.
Cut a cross in the centre of the grommet to suit the size of supply
pipe. Fig 18.
