Gas Supply Connection; Preparing Appliance For Installation - Baxi 741 Installer's Manual

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. The 'T' connector 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 hotbox and run to the 'T'
connector at the front. The pipe run from the supply line up to the rear opening in the
hotbox must be kept away from the area which will be taken by the hotbox 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, but will require
adjustment. See section 17.1
(Servicing and parts
replacement).
1. Detach the burner unit from the
hotbox by removing two screws (See figure 9). Lift the burner unit clear.
2. Fit the two "U" section seals to the bottom edges of the hotbox side flanges (See
figure 10).
3. It is important that the grommet supplied in the loose parts pack is fitted to the
hole in the rear of the hotbox.
For concealed connection only:
4. 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 unless the supply pipe is to pass through it.
