Fisher Brand R622 Second Stage Low Pressure Gas Regulator
Fisher R600 Series second stage Low Pressure regulators are UL listed designed to reduce the outlet pressure from a first-stage regulator in domestic installations. Type R622 is designed for Two-Stage domestic applications up to 1 400 000 BTU per hour / 15,8 SCMH. Type R622 contains a high performance relief valve and a large 3/4-inch screened vent to limit downstream pressure to less than 2 psig / 0,14 bar in an overpressure situation.
Fisher Type R622 second stage regulators are UL listed designed to reduce the outlet pressure from a first-stage regulator in domestic installations, commercial, and industrial applications. R622 used on natural, manufactured gas, or LPG gas.

The installed regulator should be adequately protected from vehicular traffic and damage from other external sources.
• Install the regulator with the vent pointed vertically down, see Figure 2. If the vent cannot be installed in a vertically down position, the regulator must be installed under a separate protective cover. Installing the regulator with the vent down allows condensation to drain, minimizes the entry of water or other debris from entering the vent, and minimizes vent blockage from freezing precipitation.
• Do not install the regulator in a location where there can be excessive water accumulation or ice formation, such as directly beneath a down spout, gutter, or roof line of building. Even a protective hood may not provide adequate protection in these instances.
• Install the regulator so that any gas discharge through the vent or vent assembly is over 3 feet / 0.91 meter horizontally from any building opening below the level of discharge.
• Install the regulator high enough above ground level at least 18 inches / 45 cm - so that rain splatter cannot freeze in the vent.
Regulators Subjected to Heavy Snow Conditions
Some installations, such as in areas with heavy snowfall, may require a hood or enclosure to protect the regulator from snow load and vent freeze over.
