The Mascot FT is shipped with a Natural Gas Nozzle
(Orifice) that is suitable for altitudes up to 3,000 ft. The
Mascot FT may be installed at elevations up to 10,000
ft, and it can be converted to use Propane Gas to
operate at elevations up to 10,000 ft, but to achieve
this, the Gas Line Nozzle must be changed out to suit
the installation altitude and the desired gas.
To order the Gas Line Nozzle to suit your installation
altitude and gas, please visit laars.com/support to
