1. IMPORTANT INFORMATION

Remove the control knob again, and rotate the split screw on the valve body to
the left to increase the flow rate, to the right to reduce it.
Re-install the knob to turn the burner off.
Re-install the valve cover and the control knobs by screwing in the appropriate
screws.
Caution: Make sure that there is a sufficient gap between the knobs and the front panel,
since it is necessary to fully depress the knob before rotating it when igniting the
burners.
The orifices size depends on the type of gas. The table below is provided for you to
determine which orifice should be used if the type of gas is changed.

The orifices are always replaced in the following sequence:
Remove the back panel by unscrewing the screws that keep it in place.
Screw the adjusting cone (2) and insert it into the mixing tube in order to free
sufficient space for unscrewing the orifice.
Unscrew the orifice (1) with a 7 mm flat wrench.
Install the orifice (1) corresponding to the new type of gas and tighten it.
Ignite the burner and adjust the air inlet (see table page 3) by screwing or unscre-
wing the adjusting cone (2) until you obtain a slightly blue flame showing no
separation; separation of the flame is an indication that there is too much air.
Lock the adjusting cone (2) with the locking washer (3).
Once you have changed the injectors, it is a good idea to adjust the low settings for the
burner (see Section 2).
Save the orifices removed from the appliance for future use.
Note: Gas pressure regulator setting must also be adjusted when changing fuel
type.

WARNING
The conversion kit shall be installed by a qualified servi-
ce agency in accordance with the manufacturer's ins-
tructions and all applicable codes and requirements of the autho-
rity having jurisdiction. If the information in these instructions is
not followed exactly, a fire, explosion or production of carbon
monoxide may result causing property damage, personal injury
or loss of life. The qualified service agency is responsible for the
proper installation of this kit. The installation is not proper and
complete until the operation of the converted appliance is chec-
ked as specified in the manufacturer's instructions supplied with
the kit.

For proper operation, the pressure of natural gas supplied to the regulator must be
between 6’’ and 10’’ of water column.
For LP gas, the pressure supplied must be between 12’’ and 13’’ of water column.
When checking for proper operation of the regulator, the inlet pressure must be at least
1’’ greater than the operating (manifold) pressure (see Section 1).
The gas regulator on the appliance is set at the factory for pressures given by
regulations.
The gas regulator can be adjusted by means of the following procedure:
Remove the control knob by unscrewing the screw “a” (see Section 2) that keeps
him in position.
Remove the valve cover by unscrewing the screws “b” (see Section 2) that keep it
in place. The regulator is now accessible.
The regulator has a bayonet mounted top cap. Using a small coin press in and turn
the cap to remove it.
Turn the cap over so that the letters “LP” (for propan gas) or “NAT” (for natural
gas) are visible on base of the hollow in the cap.
Replace the cap making sure that the bayonet pins are securely located.
Stick on label
Stick the appropriate label on to the data badge to indicate the gas the appliance is now
set for.
