8.7 Terminal guarding
Position the terminal guard to wall, align and ensure equal clearances around fan box.
Mark off the four fixing positions on wall. Remove the terminal guard and drill at the
marked positions, four holes using a no. 10 drill. Insert wall plugs, reposition the
terminal guard and secure to wall using four screws supplied.
9. GAS SUPPLY INSTALLATION
9.1 Gas supply connection.
1.
Connect the supply line to the appliance.
2.
Unless the supply pipe connection is from the left front side, the supply pipe will
have to be formed to avoid various components below the burner. If a visible connection
is to be made, it will be necessary to cut a small notch in the side of the fret to allow the
gas pipe to pass.
3.
If gas supply is to the rear of the appliance,
then entry is via the large grommet, at the lower
left hand side of the back face. Pierce the
grommet to allow pipe entry. Gas supply can
also be accommodated at the lower right hand
side of the appliance. This small grommet will
require removal or a careful incision for pipe
entry (See figure 33).
4.
Check the installation pipework for gas
soundness in accordance with the current
edition of BS6891.
Do not use leak detection
sprays on this appliance. Sprays may affect the
operation of electrical components. Keep all
liquid detection fluids clear of electrical
components.
A long brush may be required to
reach some joints.
9.2 Preliminary burner checks.
Some burner operations can be checked at this stage. Checking now will mean that less
disassembly will be required if any problems are found.
A full check should still be
made, however, after final installation.
!
Switch on electrical power supply to the appliance. The red indicator light at the left
side of the burner should come on.
!
If closed, open the isolating valve at the inlet elbow.
!
Press and hold in the “on” switch. Within two seconds, the fan motor will start and
the indicator light should go out.
