internal relief valve construction. The rst stage does not
have an internal relief valve. The regulators are normally
painted GRAY with a BLACK CAP.
Integral Two psig Service Regulator
The Type R632E integral two psig service regulator
contains a non-adjustable rst stage regulator on the

Installation
WARNING
!
All vents should be kept open to permit
free ow of air in and out of the regulator.
Protect vent openings against the entrance
of rain, snow, ice formation, paint, mud,
insects, or any other foreign material that
could plug the vent or vent line.
LP-Gas may discharge to the atmosphere
through the vent. An obstructed vent
which limits air or gas ow can cause
abnormally high pressure that could
result in personal injury or property
damage. Failure to use a vent line on
Indoor Installations can cause a hazardous
accumulation of gas which could result in
personal injury or property damage.
Never use a Type R622H, R622E, R632E,
or R652E (pounds-to-pounds) regulator
on low pressure (inches of water column)
service because personal injury or
property damage could occur. The
Types R622E and R652E are not suitable
for use as a “ rst stage” regulator.
General Installation Instructions
Before installing the regulator,
• Check for damage, which might have occurred
in shipment.
• Check for and remove any dirt or foreign material,
which may have accumulated in the regulator body.
