CONVERSION TO DIFFERENT TYPES OF GAS
Should the cooktop need to be converted to a gas different to the one it was intended for, the
injectors have to be replaced.
It there are no spare injectors supplied they can be obtained from Glem Gas Service.
The injectors are to be installed according to the table on the underside of the cooktop.
Injectors can be identified by the diameter expressed in hundredths of mm printed on the injector
itself.
Modify the inlet gas supply as required and fit either the Natural gas regulator or LPG test
point as appropriate.
Replacing the injectors
1. Remove the gas rings and burner caps from the cooktop.
2. Using a face spanner, replace injectors “J” (fig. 20) with those specified for the gas to be
used.
3. Reassemble the burners. The burners do not require primary air regulation
Regulating the minimum
Having replaced the injectors, ignite the burner and remove the control knob. Turn the knob to
minimum, insert a screw driver and rotate screw to decrease the flame or unscrew it to increase
the flame. (fig. 20)
The result should be a small constant flame which is even all around the burner crown.
Finally, check that the flame does not go off when quickly turning the valve from maximum to
minimum. On cooktop fitted with flame failure devices, check that the flame slightly brushes the
thermocouple. Check correct regulation by leaving the burner on for a few minutes. If it goes
off, increase the minimum.
Gas checks and adjustments – Pressure Adjustment
First shut off the gas to the appliance. Remove the sealing screw from the regulator test point
or LPG test point at the rear of the cooker and attach a hose from the mamometer to the point.
Turn the gas back and light the largest burner and smallest burner at the maximum setting.
Check the pressure and adjust at the regulator if necessary to the settings in the tableor on the
data plate. For LPG adjust at the regulator at the cylinder. Turn the regulator adjusting screw
clockwise to increase the pressure and anti clockwise to reduce the pressure. Refit the test
point sealing screw when finished.
CLEANING
To maintain the cooktop it needs to be cleaned after each use once it has cooled down.
Never remove the knobs from their housing to clean the cooktop.
Enamel parts
All enamel parts should only be washed with a sponge and soapy water or other specifically
non-abrasive products. Dry completely.
Stainless Steel
The stainless steel plane should be cleaned with a damp cloth or with specific stainless steel
cleaning products.
