4.9.2
Hold the hexagonal control lever cable locking bush with a spanner
and unscrew the locking screw using a 2mm allen key to release the
cable from the control lever. The control cable can now be removed
from the cable guide tubes.
4.9.3
To fit the replacement cable, thread the end of the new cable into the
long length of p.t.f.e. sleeve (as supplied) , taking care not to kink the
sleeve. Now carefully feed the sleeve and cable into the left hand cable
guide tube until the ends emerge above the control lever. Now thread
the short length of p.t.f.e. sleeve over the end of the cable and thread
the sleeve and cable into the top of the short cable guide tube.
4.9.4
When the end of the cable emerges from the short cable guide tube,
locate the nipple on the other end of the cable into the locating hole in
the aluminium operating arm. Thread the free end of the cable into the
cable retaining hole on the operating arm, but at this stage do not
tighten the securing screw.
4.9.5
Fit the hexagonal control lever cable locking bush onto the control
lever and fit the control cable loosely into the bush in the gap between
the two lengths of p.t.f.e. sleeve. Ensure that the cable is located in the
retaining hole in the locking bush and tighten the screw sufficiently to
retain the cable but still allowing it to slide for adjustment.
4.9.6
It is now necessary to correctly tension the operating cable. To do this,
first set the control lever to the horizontal (central position), this is the
position which creates maximum tension in the operating cable.
Pull the free end of the operating cable through the operating arm until it
is finger tight and secure with screw into operating arm (do not over
tighten).
4.9.7
Slide the operating arm fully to the right hand position and hold in
position, slide the control lever relative to the cable until the cable
retaining screw lines up with the hole in the spacer frame. This sets the
control lever in the correct position. Hold the hexagonal locking bush
with a spanner and tighten the retaining screw using the 2mm allen key.
Move the control lever fully downwards and check that the left hand
micro-switch operates the igniter and that the control valve spindle is
fully depressed. Move the control lever upwards to the “off” position
and check that the right hand (cut-off) micro-switch operates. Check
that the control lever operates smoothly and safely
.
