Gas Supply Connection; Preparing Appliance For Installation - Baxi Fires Division 740FS Installer's Manual

INSTALLER GUIDE

7. GAS SUPPLY CONNECTION

A nut and olive are provided for an 8mm pipe inlet connection to the 'T' connector at
the bottom front of the appliance. The 'T' connector can be rotated to allow a
connection from any direction and includes a valve for isolating the gas supply and a
pressure test point.
The supply pipe must be rigid material. Flexible pipe must not be used.
Concealed Supply Pipe Connection
If a concealed connection from inside 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 hole in the back of the convection box and run to the 'T'
connector at the front. The pipe run from the supply line up to the rear opening in the
convection box must be kept away from the area which will be taken by the convection
box when it is installed (See figure 7).
Note that the centre of the appliance inlet 'T' connector is 25mm above the fireplace
floor. The inlet 'T' connector should be fitted to the supply pipe at this stage.

8. PREPARING APPLIANCE FOR INSTALLATION

IMPORTANT
Before continuing with the installation
of this gas fire the aeration setting on
the burner must be checked. The
aeration is factory set for use with a
ceramic pebble fuel effect. See section
17.1 (Servicing and parts replacement).
Figure 10. Burner attachment points
1. Detach the burner unit from the
convection box by removing two screws (See figure 10).
Lift the burner unit clear.
2. Fit the two "U" section seals to the bottom edges of the
convection box side flanges (See figure 11).
3. It is important that the grommet supplied in the loose
parts pack is fitted to the hole in the rear of the
convection box.
4. For concealed connection only:
Pierce the grommet to allow the pipe to pass through it. The
grommet should envelop the pipe. If the hole is larger than
the pipe, seal it with tape. Do not pierce the grommet
