Installation Instructions
Minimum Setting or Turn Down
This has been set at the factory for NG but
may need adjusting for local conditions.
When converting to LPG, the minimum
setting MUST be reset for each burner.
To adjust the minimum setting you will need
a Ø 2.5 x 45 mm screwdriver.
1 Ignite the burner and set the knob to its
minimum position.
2 Remove the knob.
3 Rotate the turn down screw slowly until
a minimum regular flame is achieved.
(The flame will diminish when the screw
is turned clockwise and increase when
turned anti-clockwise (see fig.6).
4 Replace the knob.
5 When the setting is right check regulation
by quickly rotating the knob from the
maximum to the minimum delivery
position. The flame must not go out.

Note: CG913TM models may require
progressive venturi adjustment on the wok
burner:

the orifice.
Fig.4 Yellow Tipping - move the venturi
away from the orifice.

The label supplied with the orifices should
be placed over the existing gas type label
located on the underside of the product to
indicate the gas change.
