6.8.7
Place the fourth Torctite Coupling over the open end of the Radiant Tube (and turbulator) Assembly carrying
the Fan Assembly 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. 27). Tighten the nuts 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.
6.8.8
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. 27). Place the remaining two Reflector
Panels over the two outer Reflector Panels, ensuring that the centre overlap is as shown in Fig. 24, 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 (fastenings pack) as shown in Fig. 27. 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.
6.8.9
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); 2 clips per facet of Reflector Panel, as shown in
Fig. 27.
Repeat the procedure to attach the second Reflector End Panel to the opposite end of the Reflector.
6.8.10 If combustion air is to be ducted to the appliance attach a length of flexible ducting to the Air Inlet
Adaptor of the Control Box by use of a suitable hoseclip. Attach the inlet end of the hose to any fixed
ducting, also by use of a suitable hoseclip, allowing for adequate movement of the appliance.
6.8.11 Connect the gas supply in accordance with Section 5.2. - Gas supply, of these Installation Instructions.
6.8.12 Using twin core and earth flexible supply cable, as specified in Section 5.3.2, suitable for 230V~50Hz 125W
supply, connect the 3 pin electrical socket provided (fastenings pack) as follows:-
Brown (Red)
-
to terminal marked L
Blue (Black)
-
to terminal marked N
Green/Yellow
-
to terminal marked
7
Connect this socket to the 3 pin plug (marked 230V~50Hz) mounted in the side of the Control Box.
External fuse rating required - 3A
See Section 5.3 for electrical supply requirements.
NOTE: It is important for the correct function of the appliance for the polarity of the electrical supply to
be correct.
