10.0 Installation
10.6 Making the Gas Connection
1. Connect the gas supply to the G
Internal) gas tap. This is located on the lower right side
of the boiler, access by hinging down the PCB housing
(see Fig. 32).
10.7 Fitting The Flue
Before fitting the flue, check the condensate drain
integrity (see section 10.5).
IMPORTANT: The flue should always be installed
with at least 1.5° 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 181mm. This
dimension to be known as (X).
i.e.
(X) = wall thickness + 181
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 semi-circular 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 + 250mm.
This dimension to be known as (Z).
i.e.
(Z) = wall plate to wall + wall thickness + 250
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 semi-circular 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).
