Plumbing; Gas Connection; Condensate; Condensate Connection - Warmworld FFC 30/60 Installation & Service Instructions Manual

2. Pipes must be clipped every 1000mm, minimum.
3. The condensate connection from the Boiler
Mounting Box must be connected to the Boiler
Condensate Drain Trap. (see Fig. 12)
4. All connections should be made with the Socket
end furthest from the boiler.
5. Only CentraCerin or Silicone Grease should be
used to ease the fitting of sections.
6. The combined length of Air and Flue should not
exceed 22m horizontal, or 30m vertical and
includes any terminal parts.
7. The straight equivalent lengths of bends in a
horizontal design are as follows:
45 degrees, 1.3m.
90 degrees, 4m.
For more complex designs please see the details
provided with the components
8. The Roof Terminal must not be altered and there
should be at least 300mm from the terminal to
any part of the building.
It is recommended that:
1. The Installation of the flues are completed before
the boiler is hung on the Mounting Box. This will
ensure that any debris that gets into the flues can
be cleared.
2. That 45 degree bends are always used with
vertical flues and where possible used in prefer-
ence to 90 degree bends in horizontal installa-
tions.
3. Straight/square Flue pieces may be reduced in
length by cutting. It will ease assembly if the cut
edge is cleaned, chamfered and greased before
insertion.

Plumbing

Prepare the flow and return pipe work on the rear of
the boiler. Note: It is important that the joints on this
pipework are leakproof as access is very limited
after fitting the boiler module. Facing the boiler the
FLOW connection is at the bottom left and the
RETURN at the top right.
SECURING THE BOILER ON TO THE
MOUNTING BOX
1. Remove the two M5 screws from the Mounting
Box, and retain.
2. Remove the boiler top trim by undoing the two
Condensing Boiler
screws, and retain. For Twin Pipe Installations,
also remove the Left Hand Side Trim.
3. With the bottom of the boiler away from the wall,
hang the top of the back panel onto the Mounting
Box. Now, by gently lowering the bottom of the
boiler against the wall the fan spigot should
engage in the flue connector. Observe the correct
engagement of the fan spigot into the flue.
4. For Twin Pipe Installations, Remove the cap from
the spare inlet on the condensate trap. Offer up
the silicone drain tube from the Mounting Box and
shorten if necessary. If there is very little clear-
ance on the left of the appliance it will be easier
to connect the flue drain to the syphon by swing-
ing the bottom of the boiler away from the wall to
give more room.
IMPORTANT:
Neither of the drain tubes should
be kinked, they must run smoothly to the Con-
densate Trap.
5. Replace the two M5 screws around the fan that
hold the Mounting Box to the back panel.
6. Replace the Left Hand Side Trim and decorative
top trim, if required.
Lower Boiler Fixing
The boiler is finally attached to the wall by two
screws, washers and wallplugs.

Gas Connection

The ½" BSP. gas connection point is shown in Fig.2.
A minimum of 20mb. (8in. w.g.) must be available at
the boiler inlet, with the boiler and other connected
appliances firing. Check for gas soundness (B.S.
6891: 1988) in pipework to boiler using a manom-
eter. Open the gas cock. Gas soundness within the
boiler should be checked using sense of smell and/
or leak detection fluid. Check the burner bar pres-
sure with a manometer connected to the control and
adjust if required with the nut beneath the black
rubber cap on the underside of the valve.

Condensate Connection

The position of the plastic condensate drain pipe is
shown in Fig 2.
Where possible an internal termination of the Con-
densate discharge pipework should be used.
Installation pipework must be in plastic to a suitable
drain location with a gradient of 2.5° (45mm/ meter
run) minimum. If connected to another drainage a
trap, an air break is required between the boiler
drain and that trap. (see Fig.11). Internal runs may
