While the Intrigue was designed to hold a liquid propane tank directly beneath it, you may still prefer to
build an enclosure for larger tanks. The information in this section relates to requirements for LP
enclosures.
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 ½ 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 ½ 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 at least two openings. The
bottom of the openings must be at floor level and the upper edge can’t be more
than 5 inches (127 mm) above the floor. 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
(3.2mm) rod.
Accessibility

Cylinder valves must be readily accessible for hand operation. A door on the enclosure
to gain access to 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 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

If the enclosure has a floor, there must be a minimum clearance of 2 inches (50.8 mm)
from the lower surface of the floor of the enclosure to the ground.
