INSTALLER GUIDE

7.5 Flue restrictor adjustment.

The appliance has an integral adjustable flue draught restrictor. This is supplied set in
the fully open (unrestricted) position and in most cases no adjustment should be
necessary. It can be reset to a fully restricted position if the flue draught is excessive.
The restrictor must remain in its fully open position if the flue has an equivalent height
of 4m or less (as calculated in accordance with BS 5440: Part 1 Annex B). Generally
we recommend the restrictor is NOT fitted where a precast flue is used, however,
certain flues may work sufficiently to warrant its use. There may however, be
circumstances where closing the restrictor causes the fire to fail the spillage test. In
such cases the restrictor will have to be re-opened. After opening conduct the spillage
check again.
To close the restrictor:
1. Loosen the screw situated behind the cut-out
in the black upper heat shield. Do not fully
remove the screw (See figure 11).
2. Push the restrictor firmly down as far as it will
go. The top of the slot in the restrictor bracket
should touch the screw.
3. Fully tighten the screw.
If closing the restrictor causes the fire to fail the
spillage test it will have to be reopened.
To open the restrictor:
1. Loosen the screw situated behind the cut-out
in the black upper heat shield. Do not fully
remove the screw (See figure 11).

3. Fully tighten the screw.

8. CONTROL AND PRESSURE CHECKS

Please note:
When operating the fire for the first time, some vapours may be given off which could
set off smoke alarms in the vicinity. These vapours are quite normal with new
appliances. They are totally harmless and will disappear after a few hours use.

8.1 Check control settings.

1. Make sure the slider button is at the off (O) position (Topmost position).
2. Slide the button to the bottom. This is the ignition/ low (
L) position. Retain in this
position to ignite the pilot. The pilot flame can be seen through a hole immediately in
front of the centre radiants. The centre radiants should ignite within 4 seconds of the
