If you build an enclosure for an LP gas cylinder, follow
these recommended specifications and local codes:
Ventilation
Enclosures must be ventilated by openings at the level
of the cylinder valve and at floor level. Effectiveness must
be determined with the cylinder(s) in place.
 One side of the enclosure must be completely
open or,
 For an enclosure having four sides, a top and a
bottom:
- At least two ventilation openings at cylinder
valve level shall be provided in the side wall, equally
sized, spaced at 180 degrees (3.14 rad), and
unobstructed. Each opening must have a total free
area of not less than 1/2 square inch per pound
(3.2 sq. cm/kg
) of stored fuel capacity and not
less than a total free area of 10 square inches
(64.5 sq. cm).
- Ventilation opening(s) must be provided at floor
level and shall have a total free area of not less
than 1/2 square inch per pound (3.2 sq. cm/kg) of
stored fuel capacity and not less than a total free
area of 10 square inches (64.5 sq. cm). If
ventilation openings at floor level are in a side
wall, there must be a least two openings. The
bottom of the openings must be at floor level and
the upper edge can’t be more than 5 in. (127 mm)
above the floor. The openings must be equally
sized, spaced at 180 degrees (3.14 rad) and
unobstructed.
- Every opening must have minimum dimensions to
permit the entrance of a 1/8 inch (3.2 mm)
diameter rod.
Accessibility
 Cylinder valves must be readily accessible for
hand operation. A door on the enclosure to
gain access to the cylinder valves is
acceptable, provided it is non-locking and
can be opened without the use of tools.
 The design of the enclosure must be
such that:
- The LP gas supply cylinder(s) can be
connected, disconnected and the
connections inspected and tested
outside the cylinder enclosure.
- Those connections which could be
disturbed when installing the
cylinder(s) in the enclosure can be leak
tested inside the enclosure.
- Be certain to mount or set the LP gas
cylinder on a flat stable surface and
retain it to prevent it from tipping.
Minimum Clearances
 There must be a minimum clearance of 2 in.
(50.8 mm) between the lower surface of the
floor of the LP gas supply cylinder enclosure
and the ground.
