Removing Case; Boiler Mounting Box; Flue And Air Duct; Terminal - Warmworld FFC 30/60 Installation & Service Instructions Manual

Removal of the Case
Refer to Fig. 6
1. Lower the electrical cover. This is detached by
pulling the cover towards you and carefully
lowering. Care should be taken to prevent strain
on the cables and connections.
2. Remove the case by unscrewing the two
pozidrive screws located at the bottom and rear
of the case, and lifting and pulling forward off the
two pegs which are located at the top. The case
should be kept vertical as it is removed. Examine
the sealing strip for damage and replace if
necessary.
IMPORTANT: FAILURE TO CORRECTLY
LOCATE THE APPLIANCE CASE COULD
RESULT IN LEAKAGE OF COMBUSTION
PRODUCTS INTO THE ROOM.

Boiler Mounting Box

1. Site to suit system and terminal limitations.
2. For the Concentric Flue. Prepare the Boiler
Mounting Box for the flue direction required by
swapping one of the blanking discs for the flue
grommet.
3. Using the template, ensure the Boiler Mounting
Box is at the desired height for the top of the
See Fig. 5
boiler.
4. Mark the wall or ceiling for the flue exit points and
core drill the wall to give a 0 to 3 degree slope
down towards the boiler. The recommended core
drill for the Concentric Flue is 128mm and 90mm
for the Twin Pipe.
5. Then screw the Boiler Mounting Box to the wall
using a top hole on each side, and then any other
two, using the four screws, washers and
wallplugs supplied.
Assembly Of Flue Pipe &
Air Duct Pipe To Boiler
Mounting Box
(Concentric Flue Only)
The following is based on the flue tube being sup-
plied with the straight and elbow connectors being
pre-assembled, the one NOT required to be cut off
during installation.
Condensing Boiler
Right or Left Outlet
1. Secure the 50mm flue tube with ELBOW connec-
tor on the saddle using the Velcro strap.
See Fig. 7
2. Measure carefully and saw off the 50mm tube to
give required projection from wall.
3. Measure carefully and saw off the 110mm Air
duct tube to give required projection from wall.
The flue pipe must project more than the outer air
duct when assembled.
Note:
It is acceptable to obtain this dimension by pulling
the air duct away from the air duct stop, provided
there is a minimum of 10mm (1/2 in.) insertion
into the Boiler Mounting Box and that a satisfac-
tory seal is achieved.
4. For extended flues, position the air duct support
clips provided every 700mm.
Rear Outlet (Concentric Flue Only)
Install as above but using the STRAIGHT connector
in the Boiler Mounting Box. Follow the instructions
under Right or Left Outlet, points 1,2,3 and 4.
Terminals
Concentric
Fix to the outside wall with the screws provided. The
top has no holes and is marked 'TOP'. If a guard is
fitted, the terminal should be at its centre.
Twin Pipe
The terminal can be fixed vertical or horizontal. The
flue pipe must always be connected to the extended
outlet of the terminal. The spacing is 120mm and a
core drill of 90mm is recommended. See Fig. 2.
Single Pipe
A core drill of 90mm is recommended. See Fig. 2.

Twin Pipe Assembly

All the Twin Pipe components for this appliance are
lightweight plastic and utilise a push-fit system. Very
few fasteners are required and their use is detailed on
the instructions provided with the components.
Important:
All Twin Pipe Installations must comply with the fol-
lowing.
1. The Flue pipe must slope back to the boiler by
three degrees (1 in 20) on all horizontal runs. The
air pipe can be above or below horizontal.
