12.4.2 Extended Vertical Installation
Vertical flue lengths may be extended to the limits as stated
in Table 9 using standard 1m extension kits and 45 and 90
degree elbows.
Secure the Flashing kit to the roof.
Refer to Fig. 20.
From the roof, slide the Terminal Assembly through the
flashing kit, ensure the contact rim of the flashing kit has
slid up inside the outer tube of the Terminal Assembly.
From the appliance side, position the Terminal clamp bracket
and loosely secure to the roof. Fig. 15.
Fit the Appliance Adaptor to the top of the appliance using
3 screws provided.
Assemble the Flue Extension(s), (elbows, seals, clamps where
used), centralising springs and fixing brackets until the
dimension between the end of the Flue Tube Adaptor
Assembly and the bottom of the last Extension Tube flange
is less than 1m, measure this dimension ‘W’.
Subtract 3mm from dimension ‘W’, mark this dimension onto
the final Extension Tube, both inner and outer and cut the
plane end (Not the flange end).
Remove all burrs.
Temporarily lift the Terminal Assembly and slide the extension
tube fixing bracket (if required) and the ceiling seal onto the
outer extension tube.
Position the final Inner Extension Tube.
Position the centralising spring.
Position the final Outer Extension Tube.
Lower and reconnect the Terminal Assembly, drill (2mm drill)
through the pilot holes in the Outer Extension Tube(s) and
Appliance Adaptor. Secure using the screws provided.
Fully tighten the fixing bracket(s) on the extension(s) and
the terminal clamp bracket in the roof.
Make good around the Flashing Kit.
12.5 MAKING THE GAS CONNECTION
Note: The whole of the gas installation should be inspected
and tested for soundness and purged in accordance with
the recommendations of BS 6891.
Make up the gas supply to the connection on the gas control
Valve using the Gas Inlet Kit.
Fit the gas Isolation Valve as close as possible to the
appliance (Fig. 21).
Check for soundness prior to making the water connections.
12.6 MAKING THE WATER CONNECTIONS
Connect the appliance to the incoming cold water supply
using the Water Inlet Kit.
Fit the Isolation Valve as close as possible to the Appliance
(Fig. 21).
Connect the appliance to the domestic hot water System
using the Water Outlet Kit. (Fig. 21).
Turn on the water supply to the appliance. Open the Isolation
Valve on the inlet to the appliance, open the hot water taps
and purge the system of air.
12.7 MAKING THE ELECTRICAL CONNECTIONS
The Appliance is supplied with an integral lead and fused
Plug.
The Appliance may be permanently wired to a double pole
Isolator.
