m) Evenly tighten the tensioning nuts to tension both cables and pull the fire snugly against the
wall. Do not overtighten, it is only necessary to pull the seal up against the sealing face of the
wall, it does not need to be compressed. Check that there are no gaps behind the seal.
n) With the fire securely in place, if a concealed gas connection has been made through either of
the access holes in the sides of the fire, the holes should be closed around the pipe to prevent
leakage of air through the gap around the pipe.
o) Refit the burner in the reverse order using the four M4x 6mm pozi pan screws.
p) Refit Top Infill Panel, Pilot Heat Shield and Glass Frame as shown in section 4
q) Before making the final gas connection, thoroughly purge the gas supply pipework to
remove all foreign matter, otherwise serious damage may be caused to the gas control
valve on the fire.
2.3 GAS TIGHTNESS AND BURNER PRESSURE
a) Remove the pressure test point screw from the inlet elbow and fit a manometer.
b) Turn on the main gas supply and carry out a gas tightness test.
c) Depress the control knob and turn anti-clockwise to the position marked pilot. Hold in the
control knob for a few seconds to purge the pipe work then press the igniter button. The
burner should light, continue to hold the control knob for a few seconds then turn to the full-on
position.
d) Check that the gas pressure is 20 mbar (+/- 1.0mbar) 8 in w.g.(+/- 0.3 in w.g.).
e) Turn off the fire, remove the manometer and refit the pressure test point screw. Check the
pressure test point screw for gas tightness with the appliance turned on using a suitable
leak detection fluid or detector.
