8.6 Making the Gas Connection
1. Connect the gas supply to the RC½ (½in BSPT
internal) gas tap located on the lower right side of the
boiler.
8.7 Fitting The Flue
Before fitting the flue, check the condensate drain
integrity (see section 8.5).
IMPORTANT: The flue should always be installed with a 3º
(1 in 20) fall from terminal to elbow, to allow condensate to
run back to the boiler.
HORIZONTAL FLUE
1. The standard flue is suitable for lengths 270mm
minimum to 800mm maximum (measured from the
edge of the flue elbow outlet).
Rear Flue: maximum wall thickness - 630mm
Side Flue: maximum wall thickness - 565mm (left or right)
2. For rear exit - measure the wall thickness (Fig. 26) and
to this dimension add 235mm. This dimension to be
known as (X).
i.e. (X) = wall thickness + 235
3. Take the flue and mark off (X) from the terminal end as
indicated in the diagram (Fig. 27).
Check your dimensions.
The flue tubes are fixed together. Cut through both
tubes whilst resting the flue on the semicircular packing
pieces. Deburr both tube ends.
4. For side exit - measure the distance from the edge of
the wall plate to the inner face of the wall (Fig. 26) and
to this dimension add the wall thickness + 275mm. This
dimension to be known as (Z).
i.e. (Z) = wall plate to wall + wall thickness + 275
5. Take the flue and mark off (Z) from the terminal end as
indicated (Fig. 27).
Check your dimensions.
The flue tubes are fixed together. Cut through both
tubes whilst resting the flue on the semicircular packing
pieces. Deburr both tube ends.
IMPORTANT: Check all measurements before cutting
NOTE: When cutting ensure the cut does not interfere with
the inner flue support bracket (Fig. 27a).
