4.4.5
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 centre (short) Radiant Tube into the Torctite Coupling,
ensuring that it engages fully (up to the stop) and with the Hanger Brackets aligned with those of the first
Radiant Tube section (see Fig. 16). 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.
4.4.6
Place a Torctite Coupling over the open end of the Radiant Tube (and turbulator) Assembly f urthest from
the turbulator, ensuring that it engages fully, (up to the stop). Assemble the previously assembled section
of Radiant Tubes into the Torctite Coupling ensuring that it engages fully (up to the stop) and with all the
appliance Hanger Brackets correctly aligned with each other (see Fig. 16). Tighten the screws of the
Torctitie 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.
4.4.7
Place one Reflector Panel onto the two Hanger Brackets adjacent to the Control Box and a second
Reflector Panel onto the two Hanger Brackets adjacent to the Fan Assembly. Position the Reflector Panels
such that their outer edges overhang the Hanger Brackets by 50mm (see Fig. 16). Place the remaining two
Reflector Panels over the two outer Reflector Panels, ensuring that the centre overlap is as shown in Fig.
16, thus providing a 50mm overlap at each joint. 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). Clamp also, the third and fourth Reflector Panels where they overlap, to the
fourth Hanger Bracket (from Control Box end) end using two retainers and M6 setscrews and washers
(fastenings pack). Secure the two Reflector Panels that overlap adjacent to the centre Hanger Bracket, to
each other using two 'U' type speed clips (from fastening pack) as shown in Fig. 16. Screw the remaining
(6) retainers to each of the other Hanger Brackets to provide
location
for the Reflector Panels.
Note
: the Reflector Panels, where located but not clamped, will be free to move and compensate for
expansion and contraction caused by temperature variation.
4.4.8
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 Panel by use of six 'U' type speed clips provided (fastenings pack) ; as shown in Fig. 16.
Repeat the procedure to attach the second Reflector End Panel to the opposite end of the Reflector.
4.4.9
C onstruct and suspend the second section of the appliance by again following procedure 4.4.1 to 4.4.8.
4.4.10
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, ensure 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.
NOTE
: Tighten the Torctite Coupling screws alternately whilst continually checking for slackness of the
joint.
4.4.11
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.
4.4.12
Connect the gas supply in accordance with Section 3.2. - Gas supply, of these Installation Instructions.
4.4.13
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 DIN Type electrical socket supplied (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 socket (marked 230V~50Hz) mounted on the terminal box attached to
the Fan Adapter.
