Venting the Installed Regulator
The top of the gas regulator must “breathe” in
order to operate properly and safely. The regulator
is designed to have a small amount of air in the
top section. A vent restrictor is installed on the
vent of the regulator to allow it to breathe and
limit any escape of gas if the regulator fails.
Depending on local codes, a vent pipe may be
required in place of the vent restrictor.
Safety requires the diameter of the vent pipe
to vary depending upon its length. A short run of
pipe can have a smaller diameter than a longer
pipe. The pipe diameter should never be smaller
than 3/8" (10 mm). Follow local codes and good
engineering practices to choose the size and the
material of pipe.
The discharge end of the pipe must be
protected. A hood is needed to keep out rain,
snow, and ice, and a screen must be provided to
keep out insects that could clog the discharge.
Carefully consider the route that the pipe will
have to follow from the back of the left end frame
to the final discharge point. Make this run as short
and straight as possible. Be sure that the pipe is
protected from any mechanical damage or
restriction.
Generally accepted codes require that the
discharge be placed away from windows and
other openings. Follow the local codes for
maximum safety.
Refer to the following procedure in order to
vent the regulator.
NOTE: Replace the vent
restrictor only if local codes require
a tube vented to the outside.
1. Turn the power OFF at the main discon-
nect switch.
2. Lockout/tagout the gas supply.
3. Remove the vent restrictor (Figure 2-19,
B) from the pressure regulator (A).
4. Thread in any adapters required to in-
crease the diameter of the pipe.
5. Connect the rest of the piping to the dis-
charge point.
6. Install a hood over the discharge of the
vent to keep out rain, snow, and ice.
7. Install a screen to keep out insects that
could clog the discharge of the vent.

regulator (A) has a vent restrictor (B)
