8.1

Check the Gas Pressure and F.S.D. Operation

Remove the pressure test point sealing screw located on the gas tap and connect a
pressure gauge to the test point. Temporarily fit the control knob.
(a) Light the fire. Please refer to the Users Instructions. Turn the control knob to the
full on position marked HIGH.
(b) Check that the burner pressure is 17.5mbar ± 1.0mbar (7.0 in w.g. ± 0.4) cold.
The fire is designed to give the correct heat input on Natural Gas at 20mbar (8in w.g.)
inlet pressure and no adjustment is provided in the fire. Turn off the fire. Wait 3
minutes then turn the control knob directly to the full on position marked HIGH. The
pressure should read ZERO to confirm the FSD has shut off the gas. Remove the
pressure gauge and replace the pressure test screw. Re-light the fire and test for gas
soundness around the sealing screw using a suitable leak detection fluid.
(c) Check ignition performance.
WARNING: If you want to re-light a hot fire wait three minutes before doing so.
8.2

Refit Outer Case and Remaining Components

Pull off the knob. Replace the outer case by placing it over the fire right hand side first
and ensure that the spindle enters the hole in the knob housing before swinging the
left side of the case onto the fire. Fit four screws two each side to secure the case.
Drop the spindle washer over the spindle and refit the control knob. Refit the door
mask. Fit the decorative rail by inserting between the finials and into the holes in
same.
8.3 Instruct User (Refer to Users Instructions)
Make sure that the user understands the following:-
(a) How to light and operate the fire.
(b) Demonstrate the removal and replacement of the glass door and the removal
and replacement of the ceramics. Advise on the need to clean these items regularly.
(c) Advise that for safe and efficient operation, the fire should be serviced annually
by a Gas Safe registered Engineer.
(d) When the fire is first lit a slight smell may be noticed but this will quickly clear
away with use.
(e) Advise the customer that they should read their Users instructions before
operating the fire and always follow the advice in the Section headed "Cleaning your
Fire".
