Conversion instructions

Caution

Before proceeding with the conversion, shut off

the gas supply to the appliance prior to

disconnecting the electrical power.

Disassembly

Unscrew the venturis on the high-speed and

super high-speed burners using a 20 mm

wrench. Lift and remove the burner rings and

Pressure regulator conversion

The pressure regulator is located on the gas

supply pipe. Unscrew and remove the brass cap

is only adjustable for 4" and 10" gas pressure.

There is a blue plastic pin on the inside of the

cap, marked "NAT" and "LP". Pull this pin from the

cap and insert it the other way round. Snap the

pin into the cap. The pin must be positioned as in

the drawing above. The regulator is now

adjusted for propane gas 10" WC. (For natural

gas 4", turn the pin back.) Screw the cap back on

the regulator. The pressure regulator is equipped

with a separate connection for pressure testing

purposes. Check gas pressure. Permitted

pressures: min. 11" WC (5" WC, natural gas), max.

1/2 psi.

High speed and super high speed burner
