4.5.3.4 VERTICAL TERMINATION (See fig. 13)

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 prefer-

able to install the terminal assembly prior to fit-

ting the twin flue pipes.

Fit the appropriate flashing plate to the roof and

insert the vertical flue terminal through the flash-

ing plate from the outside, ensuring that the col-

lar 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 con-

nects to the exhaust connection on the concen-

tric 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 previ-

ous piece and onto the concentric to twin con-

verter. 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).

4.6 CONNECTING THE GAS AND WATER

The appliance is supplied with a fixing jig that

includes service valves (fig. 14). The service

valves are of the compression type. The acces-

sories pack contains sealing washers etc, for use

with the service valves.

When connecting pipe work to the valves, tighten

the compression end first then insert the sealing

washers before tightening the valve to the appli-

ance.

NOTE

It will be necessary to hold the valve with one

spanner whilst tightening with another.

4.6.1 GAS (fig. 6 & 14)

The appliance is supplied with a 15mm service

valve, connect a 15mm pipe to the inlet of the

valve and tighten both nuts.

NOTE

It will be necessary to calculate the diameter of

the gas supply pipe to ensure the appliance has

an adequate supply of gas.

4.6.2 FLOW & RETURN (fig. 6 & 14)

The appliance is supplied with 22mm service

valves for the flow and return connections, con-

nect a 22mm pipe to the inlet of each valve and

tighten both nuts.

NOTE

Depending on system requirements, it may nec-

essary to increase the size of the flow & return

pipe work after the service valve connections.
