The Spirflame system is designed to use one or more multiple Torch tips provided their total gas exit orifice does not exceed the gas feed capacity of the SF model or the SF Gas Generating Tower installation.
The automatic electronic gas pressure control in the SF keeps the gas pressure at the selected level despite changes of consumption. Within the technical specs of the generator.
The gas production of multiple SF generators can be connected or operated parallel into a single distribution line. A substantial number of such multiple generator installations set-up in so called "generator towers" have been supplied in the past years and operate very reliably.
With some excess gas rate (one SF generator 'too much') any SF gas generator might be removed from the tower for servicing during actual operation. The remaining SF units automatically take over the "lost" production.
