Making The Gas Connection - Flavel Calibre FBFC**MN2 Installation, Maintenance & User Instructions

2.7.8 To improve access to tension the screws it may be advantageous to
remove the control panel from the fire. To do this, remove the 4 off
retaining screws and on MC models, remove the control valve retaining
nut.
2.7.9 Thread a tensioning screw over both of the cables and ensure that the
tensioning nut is screwed fully up against the hexagon shoulder of the
tensioning screw (this provides maximum travel for the tensioning nut).
2.7.10 Fit a cabling pipe (found in loose items pack) and a screwed nipple on
to each of the cables and pull hand tight up against the tensioning
screw, then secure each nipple with a flat bladed screwdriver.
2.7.11 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.
Failure to purge the gas supply will invalidate the guarantee.
2.8 MAKING THE GAS CONNECTION / PRESSURE TESTING
2.8.1 The gas connection should be made to the appliance inlet elbow to
using 8mm rigid tubing.
2.8.2 Remove the pressure test point screw from the inlet elbow and fit a
manometer.
2.8.3 Turn on the main gas supply and carry out a gas tightness test.
2.8.4 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. If
lighting an RC or EFC variant, please consult section 3.5 to 3.10.
2.8.5 Check that the gas pressure is 20.0 mbar (+/- 1.0mbar) 8.0 in w.g.(+/-
0.4 in w.g.) for NG models and 37.0 mbar (+/- 1.0mbar) 14.8 in
w.g.(+/- 0.4 in w.g.) for LPG models
2.8.6 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.
