Installation Of The Gas Supply - Flavel Rocco HE FPHL RN2 Series Installation, Maintenance & User Instructions

2.5 INSTALLATION OF THE GAS SUPPLY (INTO STUDDED WALL OR
EXISTING CHIMNEY BREAST)
Before installing the combustion chamber, decide from which side or if a rear
connection to the gas supply is required. Plan the pipe run to enter the below the
firebox from the left, right or rear and connect to the inlet elbow. See figure 10, 11
& 12 below.
Note : Before breaking into the gas supply a pressure drop test should be
carried out to establish that the existing pipework is sound. Always insert
the grommet into the entry point used (a sharp blow with a hammer or chisel
will be sufficient to knock out the opening selected in the firebox) and with
the grommet fitted cut with a sharp knife to allow the supply pipework to
pass through into the firebox.
