Line Pressure Regulators
*** APPLICATION NOTES ***
1. The Governor regulator is ANSI Z21.80a and ANSI Z21.18 certified for vent limited
installations (indoor installations where a vent line is not required) depending upon
local codes and standards requirements. Per the terminology of the standard there is
no "vent less regulator", they are vent limited because they can leak up to 2.5 cu.ft.
per hr. (1 cu.ft. per hr. propane) per the code. The regulators per code can be
installed without installing a vent line but again are technically termed "vent limited"
per the standard not vent less.
2. The tables listed are guidelines in capacity. The actual capacity can differ based on
inlet and outlet piping, type of equipment installed and flowing differential pressure of
the system.
3. The Governor is a bubble tight full lockup regulator (it will not leak gas downstream
when it shuts off). Lock up of the Governor is certified to CSA ANSI Z21.80a
standards. Lock up in any given installation can vary based on, piping, snap acting
gas valve on high efficiency equipment, firing rate at the time of equipment shut off,
debris in the line, temperature, as well as many other variables. You may see
variations in lock up in some installations due to the above Pietro Fiorentini will not
guarantee the lock up will meet your equipment requirement due to these variations
in installations and piping.
4. The low Capacity GOVERNORS 1/2" - 1" are intended for use on equipment such
as unit heaters or simple on/off furnace applications.
5. Use the High Capacity GOVERNORS on all "High Efficiency" quick acting gas valve
applications, such as generators, pool heaters, or high turn down boilers. Install a
regulator on each individual piece of equipment. Size the regulator at minimum 50%
to 100% of listed capacity to minimize high lock-up. Make sure you match the
regulator pipe size to the pipe size of the equipments gas train and design the
piping to minimize pressure drop to 1" W.C. between the regulator and the gas train.
6. Try to match the GOVERNOR regulator to the pipe size of the equipment and
minimize pressure drop between the regulator and equipment to 1" W.C.. Minimize
the amount of elbows and fittings between the regulator and the equipment and use
full port ball valves not plug valves or reduced port valves.
7. Be careful on applications where you increase the outlet piping more than 1
diameter. You may need to install an external control line in the larger piping. The
GOVERNOR can be ordered with or retrofitted with an external control line.
8. Make sure on all installations you don't install the regulator directly at the equipment.
Install the regulator 3 to 10 feet away depending on the application.
9. Never install the external brass vent limiter outdoors. For outdoors installation install
appropriate vent protection.
10. All GOVERNORS include an inlet filter. The filter and/or regulator may be cleaned by
removing the bottom plate Torx security screws, bottom plate assembly, then
remove the filter. The filter can then be cleaned with detergent or Buna compatable
solvent and dried. The valve and orifice can be cleaned with a cloth while the bottom
plate is off. Then reassemble the unit.
11. If there are ever any questions on the installation or application of the Governor
regulator, immediately contact your local authorized distributor or representative.
12. The maximum inlet pressure on the regulator label is the required maximum
pressure of the CSA ANSI Z21.80 rating. It is not always the maximum allowable
operating inlet pressure of the regulator. The rating is a CSA requirement.

Line Pressure Regulators
Introduction
Pietro Fiorentini’s GOVERNOR line of gas regulators are designed to comply with the latest CSA and international
standards for regulators suitable for indoor and outdoor installations with no modifications.
The GOVERNOR family of regulators are ideal for a wide range of residential through large industrial applications.
The materials and soft parts used in the construction of the GOVERNOR regulators make them suitable for use with
natural gas, LPG, Propane air and other non-corrosive gases.
All GOVERNOR regulators are equipped with balanced valve design for improved high outlet pressure accuracy
regardless of Inlet pressure variation. The double diaphragm with integral vent limiter provides added security. The
external vent limiter reduces piping costs and the need for costly vent piping for indoor installations and complies
with CSA guidelines.* The number of high capacities and regulator options sometimes eliminates the need for
separate units and significantly reduces installation costs.
Safe, Reliable and High Performance
■
Internal vent limiter: non removable, for indoor and outdoor installations.
■
External vent limiter option for indoor installations.*
■
Double diaphragm for added safety and greater reliability of service.
Balanced valve design gives you for increase capacity, high 500
■
to 1 turndown and stable regulation from low to high flow.
Complete lockup in absence of gas flow, 100% bubble tight
■
shutoff.
Filter included in high capacity model.
