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. 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. 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

8.1 Appliance preparation.
1. Remove any transit tape and packing and inspect for any evidence of mishandling
which might affect the performance. Each unit is flame tested before it leaves the
factory and as a result there may be slight discolouration around the burner ports.
2. Detach the burner unit from the
hotbox by removing two screws (See
figure 9). Lift the burner unit clear.
IMPORTANT
Before continuing with the
installation of this gas fire the
aeration setting on the burner
must be checked. The aeration is

hole in the rear of the hotbox.
4. There is a length of self adhesive foam seal supplied with the fire. This will need to
be fitted to the outer rear edges of the side and top flanges of the hotbox. Cut the foam
