INSTALLATION
STEP 1.
(a) Remove the air inlet plate on
the bottom right hand corner on
the front of the cooker.
(b) Remove the blanking plate on
the bottom left hand corner on
the rear of the cooker.
(c) Fix the blanking plate to the
front of the cooker.
(See Fig. 2 & 3).
STEP 2.
(a) Fit the primary air spigot (item
4) to the back of the cooker.
(b) Make two openings through the
wall, one a 150mm (6”) and
one 250mm (10”) diameter,
where the cooker is to be locat-
ed. The 150mm (6”) opening is
for the primary air inlet duct.
The 250mm (10”) is for the twin
wall insulated section of flue
connector. See (Fig.4) for
fixing centres.
STEP 3.
(a) Position cooker against wall
allowing for the minimum clear-
ance. (See cooker clearances
in instruction manual).
(b) Cut the air inlet duct (item 5) to
the required length, allowing for
the connection to the cooker,
the cooker wall clearance and
air inlet terminal. (item 6)
(c) Push on Air inlet duct (item 5)
over the primary air spigot (item
4) and secure using one of the
jubilee clips provided. (item 7)
STEP 4.
(a) Fit cast iron bend to the cooker.
(b) Connect the telescopic section
of flue connector to the cast iron
bend by passing it through the
wall.
(c) Measure the length of flue nec-
essary to connect from the
bend on the cooker to the fan
flue. Cut the section of twin wall
insulated flue to the required
length and refit the end piece.
(d) Connect the section of flue to
the cast iron bend by passing it
through the wall.

FT 20 G POWER FLUE KIT ASSEMBLY
SEE EXPLODED VIEW (FIG 8) WHEN ITEM NUMBERS ARE REFERRED TO:
STEP 5
(a) Remove the fan cover by
unscrewing the two corner
screws as shown in fig.5. This
will allow the cover to be lifted
off. (see Fig.6)
(c) Connect the fan to the insulated
flue section and fix to the wall as
per Fig.8.

STEP 7.
(a) Connect the air inlet terminal
(item 6) to the flexible duct
(item 5) and tighten using the
remaining jubilee clip (item 7).
ELECTRICAL CONNECTION
STEP 1.
Isolate the mains supply to the
cooker.
STEP2.
Open the right hand side of the
cooker and pull out the control tray
which holds the printed circuit board.
Fix the speed controller to the tray
as shown in Fig.9.
STEP 3.
Feed the connection cable through
the air inlet terminal until it can reach
both the fan flue terminals and the
speed controller terminals. It is rec-
ommended to protect the section of
connection cable from the fan flue to
the air inlet terminal with galvanised
trunking.

STEP 4.
Connect the speed controller to the
cooker loom by first removing the
blanking 6-way connector and then
replacing it with the 6-way connec-
tor coming from the speed con-
troller. Connect the live (brown
wire) and neutral (blue wire) to the
two terminals on the speed con-
troller and also to terminals 1 & 2
on the fan flue. Connect the earth
wire to the eyelet provided on the
fan flue and to the earth connection
block on the printed circuit board
near to the speed controller.
STEP 5.
Reinstate the electrical supply.
COMMISSIONING
STEP 1.
Turn the 3 speed controllers to the
max position (fully clockwise).
STEP 2.
Turn on the boiler burner on its own
and adjust the draught to .04” wg
(1mm wg) using the speed con-
troller marked boiler.
Turn on both burners together and
adjust the draught to the above
requirement using the speed con-
troller marked boiler & oven. Turn
off the boiler burner leaving the
oven burner running on its own,
adjust the draught to the above
requirement.
STEP 3
Run both burners for approximate-
ly 10-15 minutes, repeat Step 2. as
the draught will change as the
appliance heats up.
STEP 4
Check the combustion gas rate and
the combustion and compare to the
table below.
TABLE 2
NOTE: It is essential that the
draught be correctly set as it can
effect the input rate of the appli-
ance.
IMPORTANT: Air inlets to the
appliance and FT20 must NOT
be obstructed.
