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.
Horizontally Installed Regulators
Horizontally mounted regulators, such as found in single
cylinder installations and ASME tanks, must be installed
beneath a protective cover or under the ASME tank
dome, refer to Figure 3. If possible, slope or turn the
vent down suf ciently to allow any condensation to drain
out of the spring case. Be careful that the slot in the
tank dome or protective cover for the regulator’s outlet
piping does not expose the vent to the elements. The
rst stage vent on the Types R632A and R632E should
be pointed down.
