4.3.5
Place a Torctite Coupling over the open end of the Radiant Tube carrying the Control Box ensuring that it
engages fully, up to the stop. Assemble the second Radiant Tube into the Torctite Coupling ensuring that it
engages fully, up to the stop with the Hanger Brackets aligned with those of the first Radiant Tube section
(see Fig. 13). Tighten the screws of the Torctite Coupling to secure the two sections of Radiant Tube to
one another, taking care to maintain the tubes in a straight line.
NOTE
: Tighten the Torctite Coupling screws alternately whilst continually checking for slackness of the
joint.
4.3.6
Place two of the Reflector Panels onto the Hanger Brackets and position their outer edges such that they
overhang the outer Hanger Brackets by 80mm (see Fig. 13). Place the third Reflector Panel over the two
previously positioned Reflector Panels to provide a 50mm overlap at each end. Clamp the first and second
Reflector Panels, where they overlap, to the second Hanger Bracket (from Control Box end) using two
retainers and M6 setscrews and washers (fastenings pack). Secure the outer end of the centre Reflector
Panel to the Reflector Panel furthest from the Control Box using two U type speed clips (from fastenings
pack) as shown in Fig. 13. Screw the remaining (6) retainers to each of the other Hanger Brackets to
provide
location
for the Reflector Panels as shown in Fig. 13.
Note
: the Reflector Panels, where located but not clamped will be free to move and compensate for
expansion and contraction caused by temperature variation.
4.3.7
Position one Reflector End Panel over the Radiant Tube and into one end of the Reflector Panels with the
End Panel flange flush with the end of the Reflector Panel. Secure the Reflector End Panel to the Reflector
Panels by use of six 'U' type speed clips provided (fastenings Pack) ; as shown in Fig. 13.
Repeat the procedure to attach the second Reflector End Panel to the opposite end of the Reflector.
4.3.8
Construct and suspend the second section of the appliance by again followi ng procedure 4.3.1 to 4.3.7.
4.3.9
Place one Torctite Coupling over the open end of each Radiant Tube, ensuring that they engage fully (up to
the stop). Assemble the Duplex Fan Assembly to the Radiant Tubes, ensuring that it engages fully into
each Torctite Coupling (up to the stops) and has the exhaust outlet positioned to suit the flue requirement,
i.e. either vertical or horizontal to either side. Tighten the screws of the Torctite Coupling to secure the
Duplex Fan Assembly to the two Radiant Tubes, taking care to support the Duplex Fan Assembly in line
with the axis of the tubes. ( see Fig. 15)
NOTE
: Tighten the Torctite Coupling screws alternately whilst continually checking for slackness of the
joint.
4.3.10
If combustion air is to be ducted to the appliance, attach a length of flexible ducting to the Air Inlet Adaptor
of each Control Box by use of a suitable hoseclip. Attach the inlet end of the hoses to any fixed ducting,
also by use of suitable hoseclips, allowing adequate movement of the appliance.
4.3.11
Connect the gas supply in accordance with Section 3.2 - Gas supply, of the installation instructions.
4.3.12
Using twin core and earth PVC covered flexible supply cable (as specified in Section 3.3.2 ., suitable for
230V~50Hz 125W supply), connect the DIN Type electrical socket provided (fastenings pack) as follows:-
Brown (Red)
-
to terminal marked 1
Blue (Black)
-
to terminal marked 2
Green/Yellow
-
to terminal marked
7
Connect this electrical socket to the plug (marked 230V~50Hz) mounted on the terminal box attached to
the Fan Adaptor.
4.3.13
Using twin core and earth PVC covered flexible supply cable (as specified in Section 3.3.2 ., suitable for
230V~50Hz 125W supply), connect the two remaining 3 pin electrical sockets provided (fastenings pack)
as follows:-
Brown (Red)
-
to terminal marked L
Blue (Black)
-
to terminal marked N
Green/Yellow
-
to terminal marked
7
Connect these electrical sockets to the 3 pin plug (marked 230V~50Hz) mounted in the side of each
Control Box.
External fuse rating required - 3A
See Section 3.3 for electrical supply requirement.
NOTE: It is important for the correct function of the appliance for the polarity of the electrical
supply to be correct.
