CHANGING ORIFICES
3. Use a nut driver or deep socket wrench (9/32" or 7 mm) to remove the two orifices from the
orifice holder. Install the new orifices and remount the burner base in the same manner it was
removed. Repeat this process for the secondary burner if applicable. Consult the table on pg. 5
for identification of orifices. The sizes are stamped on the orifice.
CHANGING REGULATORS
GAS SUPPLY
The local gas authority or supplier should be consulted at the installation planning stage in order to
establish the availability of an adequate supply of gas (NG or LP). If it is a new installation, have the
gas authorities or supplier check the meter size and piping to assure that the unit is supplied with the
necessary amount of gas supply and pressure to operate the unit(s).
Gas connections should be made by a qualified plumber, or your professional outdoor appliance
service technician.
All fixed (non-mobile) appliances must be fitted with an accessible upstream gas shutoff valve as a
means of isolating the appliance for emergency shut off and for servicing.
Make certain new piping and connections have been made in a clean manner and have been purged
so that piping compound, chips, etc. will not clog regulators, valves, orifices, or burners. Use pipe
joint compound / thread sealant approved for natural and LP gases.
