GAS TYPES
NATURAL GAS G20
L.P.G. G30/31
The coupling must be metal and the pipe may be rigid or flexible. Make sure that the flexible metal pipe that is fitted to
the gas coupling does not touch overheated parts and is not twisted. Use fixing clips that comply with installation
standards. Fit stopcocks or gate valves whose internal diameter is not less than the above connecting pipe. After
connecting the pipe, make sure that the joints and couplings have no leaks. Use soapy water or a purposed signed foam
product to detect leaks.
NEVER USE NAKED LIGHTS!
Switch off the appliance, disconnect the gauge and close the seal screw without forgetting to insert the washer (Ref. C)
and contact the gas company to test main gas supply pressure.
A pressure adjuster may have to be fitted upstream of the appliance.
1.5 CONNECTING TO A DIFFERENT TYPE OF GAS
REPLACING MAIN BURNER NOZZLE (Fig. 5)
REPLACING THE PILOT BURNER NOZZLE (Fig. 6)
ADJUSTING PRIMARY AIRSUPPLY TO MAIN BURNER (Fig. 5)
- Unscrew the bolt (Ref. D) that fixes the bush that adjusts the primary air supply (Ref. C).
- Position the bush (Ref. C) at distance "X" according to the type of gas installed (see 'primary air ' on the
specifications table).
- Tighten the fixing bolt again (Ref. D).
- Seal the adjusted part with tape to prevent tampering.
N.B.: the primary air supply has been correctly adjusted when it can be guaranteed that the flame will not detach it self
when the burner is cold and if there is no blow-back when the burner is hot.
Once the gas conversion operations have been completed, check the dismantled parts for leaks using soapy
water or foam products. DO NOT SEARCH FOR LEAKS WITH NAKED LIGHTS.
1.6 CONNECTING TO THE POWER SUPPLY
- Before connecting to the power supply, make sure that the power supply is compatible voltage and frequency
values displayed on the rating plate.
- The supplied appliance is designed to perform the operation specified on the rating plate located inside the
door.

CHECKING GAS PRESSURE
The appliance must be supplied with one of the types of gas
whose properties and pressure are set out in the table below:
Connect the appliance to a special gas pipe with an internal
25
diameter of at least 16 mm for G1/2" connections and a
diameter of at least 20 mm for G3/4" connections.
Gas supply pressure must be measured at the pressure point
(Fig. 4)-(Ref. B) after removing the sealing screw (Ref. A). Use a
flexible pipe, connect a gauge e.g. a liquid gauge that is
accurate to 0.1 mbar) to the pressure point (and measure the
intake pressure whilst the appliance is operating. If the pressure
reading does not fall within the upper and lower limits indicated
on the table, the appliance cannot be installed.

- Open door or doors.
- Remove oil collection trays.
- Loosen nozzles (ref. B) and replace them with nozzles
that are suitable for the gas specified on the rating
plate (Fig. 3).
The nozzles are marked in hundredths of a millimeter.
- Unscrew screwed-on cap (Ref. 2), remove the
nozzle (Ref. 3) and replace it with one that is
suitable for the type of selected gas
- Refit the screwed-on cap.
- Use a foam product to check that the cap does
not leak.
After converting or adapting for the gas, the plate
specifying the type of nozzles used MUST beef fixed
above the rating plate.
