GAS SUPPLY CONVERSION
1.
Check that the diameter of the injector contained in the kit is correct for the appliance (see
Table 3.1
).
2.
Close the gas-inlet appliance isolating valve and isolate the electrical supply.
3.
Remove the burner by first detaching the gas pipe and the electrode cables and then undoing the
retaining nuts (Item A
in
Figure 13.2
).
4.
Withdraw the burner assembly from the appliance and detach the inlet manifold.
5.
Unscrew the injectors (Item B
in
Figure 13.2
) and replace them with the ones contained in the kit. Fully
tighten the injectors to ensure gas soundness.
6.
For models LBF221, 301 & 401 fit the air regulator plate (Item C
in
Figure 13.2
) to the inlet manifold.
7.
Remove the dust cap (Item D in
Figure 13.2
) and turn the pressure governor screw clockwise until it
stops.
8.
Replace the dust cap (Item D in
Figure 13.2
). Once reinstalled the dust cap should be marked with an
anti-tamper indicator.
9.
Loosen the outlet test point screw (see
Figure 12.3
) and attach a manometer. Start up the water heater
and adjust the inline governor to give a pressure at the burner of 28.0 mbar.
10.
Position the label contained in the conversion kit on the gas valve (over the existing label), in order to
identify that it has been set for LPG G31.
11.
Test for gas soundness and inspect all joints with leak detection fluid.
