the plain end of the extension. Remove any burrs,
and check that both seals are located properly.
Seal the flue terminal assembly to the wall using
cement or a suitable alternative that will provide
satisfactory weatherproofing. The interior and
exterior trim can now be fitted.
4.5.3.3 VERTICAL TERMINATION (see fig. 11)
The twin flue system must be converted to the
dedicated concentric flue kit for termination.
●
The vertical terminal is supplied with a built-in
converter box and cannot be shortened.
●
A 130mm hole is required for the passage of
the concentric terminal through the ceiling and/
or roof.
Depending on site conditions it may be preferable
to install the terminal assembly prior to fitting the
twin flue pipes.
Fit the appropriate flashing plate to the roof and
insert the vertical flue terminal through the
flashing plate from the outside, ensuring that the
collar on the flue terminal fits over the flashing.
Push-fit the twin flue pipes onto the concentric to
twin converter ensuring that the exhaust pipe
connects to the exhaust connection on the
concentric to twin converter.
If necessary cut the plain ends (male) of the twin
flue pipes to allow connection to the concentric
to twin converter.
NOTE
●
Before cutting twin flue pipes ensure
allowances have been made for connection
onto the previous piece and onto the concentric
to twin converter. The last twin flue pipes must
be pushed 50mm onto the male spigots of the
concentric to twin converter.
●
You must ensure that the entire flue system is
properly supported and connected.
●
Ensure that any horizontal sections of pipe have
a 1
°
fall towards the appliance (17mm per
1000mm).
●
The convertor box on the vertical terminal will
have to be temporarily removed when inserting
the terminal through the flashing.

CONNECTING THE GAS AND WATER
The appliance is supplied with an accessories
pack that contains sealing washers and service
valves.
When connecting pipe work to the valves, tighten
the compression end first, then insert the sealing
washers before tightening the valve or connection
to the appliance.
NOTE
It will be necessary to hold the valve with one
spanner whilst tightening with another.
4.6.1
GAS (see fig. 12)
The appliance is supplied with a 1/2 inch BSP
service valve, connect the supply pipe to the inlet
of the valve and tighten the connecting nut.
NOTE
It will be necessary to calculate the diameter of
the gas pipe to ensure the appliance has an
adequate supply of gas.
4.6.2
FLOW & RETURN (see fig. 12)
The appliance is supplied with 22mm service
valves for the flow and return connections, connect
a 22mm pipe to the inlet of each valve and tighten
both nuts.
4.6.3
SAFETY VALVE (see fig. 12)
Connect a suitable coupling and 15mm pipe to
the safety valve outlet and tighten.The discharge
pipe must have a continuous fall away from the
appliance to outside and allow any water to drain
away thereby eliminating the possibility of freezing.
The discharge pipe must terminate in a position
where any water - possibly boiling - discharges
safely without causing damage or injury, but is
still visible.
