8.3 Check burner pressure.
The appliance is pre-set to give the correct heat input at the inlet pressure shown in
section 4 of this manual. No adjustment is necessary. Check the burner pressure by
fitting a pressure gauge at the test point. The test point is on the pipe connecting the
gas tap to the lower injector. Check the pressure with the appliance alight and set at
maximum output (Control knob position 4).
After checking, turn off the appliance. Remove the pressure gauge and replace the
test point sealing screw. Relight the appliance. Turn to the maximum output position
and test around the sealing screw for gas soundness with a suitable leak detection
fluid.
If all the above checks are satisfactory, continue with the installation. If not, check the
control and ignition circuitry and components as described in the servicing section of
this manual.
9. SPILLAGE CHECK
1.
Close all doors and windows in the room containing the fire.
2.
Light the appliance and set the control knob to the maximum position (Position 4).
3.
Leave the appliance on for seven minutes.
4.
Insert the smoke match tube (with lighted match) into the side of the appliance and
against the back panel. Position the tube so that it is horizontal, against the back
panel and with its top edge touching the side of the draught diverter box. Slide the
tube until the indent in
the tube is level with
the diverter side (See
figure 14).
5.
The installation is
satisfactory if the
smoke is drawn into
the diverter box. If an
appreciable amount of
smoke escapes from
above the flue spigot or
from the sides leave
the appliance alight at
the maximum setting
for a further ten
minutes and then
repeat the test. If the
test is still unsatisfactory disconnect the appliance and seek expert advice.
