The Pietro Fiorentini 1/2″ – 4″ Governor gas regulators comply with and are certified to CSA 6.22a-2005 and ANSI Z21.80a-2005 for 2 PSIG inlet applications. The Pietro Fiorentini Standard Governor design incorporates an integral vent limiter in the regulator. To ensure the installation complies with CSA 6.22a-2005 and ANSI Z21.80a-2005, the vent cap should be left in place and at no time should any restriction or plug be installed in the vent cap of the regulator.
When using an external vent limiter, the flat top of the vent limiter must always be facing up, with the threads facing down, so it operates properly.
