3.8.3. Continuation of Installation - Detached Control Model
1. Ensure that the gas pipes are routed
such that they do not get accidentally
damaged.
2. Do not add any other controls to the fire.
Only use the controls supplied.
3. Ensure that the control valve is not fitted
in areas where it is likely to get very hot
and /or get accidentally damaged.
4. The control valve should be adequately
protected to prevent young children
playing with it.
5. As the length of the thermocouple lead is
fixed, the remoteness of the control valve
can be a maximum of 750mm (for
Natural Gas) from the pilot if control is
fitted in line and level to the pilot. This
distance is a maximum of 400mm for
LPG models.
Under no circumstances should
the thermocouple leads be
modified or replaced by a
different type of thermocouple.
6. Find a suitable position for fixing the
control valve and mark, drill and fix the
control mounting bracket with the valve
mounted on it.
7. For
Remote Control
and
Total Control
models repeat the above procedure to fix
the heat shield for the receiver in close
proximity of the valve.
8. Choose a suitable route for the gas pipe
from the control to the underside of the
burner tray. Avoid too many sharp
bends in the pipe.
9. Form the supplied tubing to the shape of
the route taken and cut off any excess
length if necessary.
10. Connect one end of the formed tubing to
the injector elbow or tee on the
underside of the burner tray with the nut
and olive supplied, and the other end to
the outlet of the control valve (located on
top left hand of the valve) using the male
nut and olive supplied.
NOTE: If it is deemed that the
temperature around this tubing
will rise above 100 deg. C then
steel tubing must be used.
11. Form the pilot gas supply tubing and
connect the appropriate ends to the pilot
burner and the control valve.
12.
Unwind the thermocouple lead and
connect to the rear of the control valve
ensuring not to overtighten the nut.
13. Connect the HT lead to the underside of
the electrode.
14. Secure the HT lead, thermocouple lead
and the pilot tubing to the gas supply
tubing to the burner using the tie strap.
15. Connect a suitable gas supply via the
isolating valve (supplied) to the control
valve inlet.
16. Proceed to
Section 0
to commission the
appliance.
Extra vigilance is required when carrying
out the gas soundness check.
