4.1 HEALTH AND SAFETY
Blackheat cannot be responsible for ensuring that all
appropriate safety measures are undertaken prior to
installation; this is entirely the responsibility of the
installer. If manufacturer installs the appliance, it is
essential that the contractor, the sub-contractor, or
the owner indicate the presence of combustible mate-
rials or halogenated hydrocarbons anywhere in the
premises.

Notwithstanding their limited scope, the appliance
should be installed in accordance with relevant
National Codes.
4.3 CLEARANCES TO COMBUSTIBLES
Before proceeding with installation, ensure that
proper clearances to combustible materials will be
observed in the final installed position of the heater.
Clearance distances may be found in Section 2 of
these instructions.

4.4.1 Prepare a work area corresponding to the size of
heater selected. The area should be clear and free of
debris. The manufacturers approved layout drawing
should be referred to so that the work area is conve-
nient for the final system position.
4.4.2 Layout the appropriate Figure (9, 10, 11, or 12,
depending on heater model) and keep it at a conve-
nient place for frequent reference. Pull out every part
from the package and lay them out roughly at the
position shown in the assembly drawing. Keep the
bolts and screws at a convenient place for later
usage.

4.4.3 Prepare the hanging chains at the position where the
heater will be located. Chains used should have 100
kg minimum breaking load and preferably should be
galvanised finish. Assemble the two halves of the tube
clamp package using the hex carriage bolt, hex nut
and flat washer. Attach the clamp to the tube and
reflector hanger, and slide the hanger into place on
the burner tube (see Figure 6).
4.4.4 The hanger must be located within 150 mm of the
flange. Slide the next tube and reflector hanger onto
the end of the burner tube. Making sure that the sus-
pension hooks of the hangers are uppermost, lift the
burner tube into the position required. Suspend the
burner tube by connecting the tube and reflector
hangers to chains using the quick links provided.
4.4.5 Slide another tube and reflector hanger onto the next
tube and locate it according to the appropriate Figure.
Lift the tube into its position and connect it with the
burner tube using a stainless steel coupling. Repeat
this procedure to suspend the remaining tube(s) and
connect them to the heater one by one.
4.4.6 For details of the coupling connection, see the follow-
ing diagram:

Coupling
When assembling coupling, the wide end of
the slide bar moves toward the lanced clip
C L
Orient coupling so that the impact
block is above tube centerline.
Figure 8. Coupling Assembly
To assemble the coupling, hook the free end of the
coupling sleeve into the lanced clip. Place the wide
end of the tapered slide bar on the coupling so that it
moves toward the lanced clip. Insert the two tube ends
into the coupling. Be sure the tube ends are in line
and are flush against the stop pins inside the cou-
pling.
Hammer-drive the slide bar until the coupling is
secured snugly to the tubes. Overdriving the slide bar
will distort the coupling or slide bar lip and will
decrease the holding capability of the coupling.
