CHANGING ORIFICES 
(continued)
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.
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.
