GAS CONVERSION FOR RJGR SERIES
All Jade cooking appliances are designed and engineered to operate efficiently and safely with either natural or propane gas. However,
each gas requires its own specific regulator and gas orifice setting. The name plate on your unit identifies its original gas setting. This conversion must
be done by an approved service agent.
WARNING: TURN OFF GAS AND ELECTRICAL SUPPLY BEFORE
ANY PROCEDURE BELOW IS PERFORMED.
A) REGULATOR CONVERSION PROCEDURE (See Figure A)
The regulator can be converted by turning the regulator cap over. The marking on the cap for the
type of gas setting will be exposed.
B) ORIFICE CONVERSION PROCEDURE (See Figure B)
1) Remove the orifice hood from the valve or bi-metal valve. Extreme care should be taken to avoid damage to threads on the
orifice and/or valve.
2) Make sure that all internal surfaces of the new orifice and valve are clean.
3) Make sure that dirt, dust, and other contaminants are not allowed to get inside the valve or orifice hood during assembly.
4) Install new orifice hood by carefully screwing it onto the valve or bi-metal valve. Follow proper orifice sizes indicated on chart
below.
5) Adjust air shutters for optimum burner performance.
WARNING: IN ORDER TO AVOID A FIRE OR AN EXPLOSION CAUSING PROPERTY DAMAGE,
PERSONAL INJURY, OR DEATH, EXTRA-PRECAUTION SHOULD BE TAKEN
WHEN CONVERTING FROM NATURAL GAS TO LP-PROPANE BY FOLLOWING
CORRECT ORIFICE SIZES AS SPECIFIED ON CHART BELOW.
WARNING: ALL ORIFICES WITH NO EXCEPTION MUST BE CONVERTED.
Before turning the gas supply on, check for leaks and make sure that all control knobs are turned OFF.
