6. TECHNICAL INSTRUCTIONS
GAS BURNERS
12” GRIDDLE
Burners are from zinc alloy, of spear design. The front of the burner is fitted over
injector nipple and supported by the front baffle. The rear pf the burner is mounted
on to a support between the left and right hand baffles. To adjust the air ratio, loosen
screw on throat of burner and rotate the slide.
GPG-30, GPG-45, GPGDB-24, GPGDB-48
These are a heavy duty grey cast iron “H” Burner supported by the front of the
venturi at the burner the injector nipple and on the rear by a formed 18-gauge mild
steel runner. The burners protrude through to the front of the appliance to engage the
injector nipple. To adjust the air ratio, loosen screw on burner throat entrance and
rotate slide around.
SALAMANDER GRIDDLE
The griddle Salamander has long square cast iron burners, with drilled ports. An
interrupter screw is fitted immediately after the aspirator to give flame control. There
are 3 types of burners, the left hand/right hand/and the middle burner.
PILOTS
Polidoro 509f3. Gas to pilot is controlled through an injector spud. This spud needs to
be replaced when converting between L.P. and N.G. If appliance cannot be correctly
adjusted, advise the local gas authority or the appliance manufacturer.
Sit 3-way pilots are used on the GPGDSA-24/36. The needle needs to be changed for
conversion between N.G. and L.P.G. To adjust pilot flame size remove the screw
cover on the back of the pilot then adjust the screw to set the desired flame size
(turning screw clockwise will decrease the flame size).
INJECTORS
GPG 30/45
12mm hexagon brass rod 114mm long turned down to 11.0mm for 28.0mm long. The
remaining 11mm are turned down and threaded 6mm BSP. Centre drilled to 5.0mm
leaving an enclosed end 1.5 thick into which is drilled the appropriate orifice.
