front side, the supply pipe will have to be formed to
avoid various components below the burner. If a
visible connection is to be made, it will be necessary
to cut a small notch in the side of the fret to allow
the gas pipe to pass.
3. If gas supply is to the rear of the appliance, then
entry is via the large grommet, at the lower left hand
side of the back face. Pierce the grommet to allow
pipe entry (See figure 29).
4. Check the installation pipework for gas soundness
in accordance with the current edition of BS6891.
