3.3 ENCLOSURES FOR LP GAS SUPPLY SYSTEMS
If you build an enclosure for an LP gas cylinder, follow these recommended specifications. You must also fol-
low local codes.
Enclosures for LP gas supply cylinders shall be ventilated by openings at the level of the cylinder valve and at
floor level. The effectiveness of the opening(s) for purposes of ventilation shall be determined with the LP gas
supply cylinder(s) in place. This shall be accomplished by one of the following:
3.3.1
One side of the enclosure shall be completely open;
OR
3.3.2
For an enclosure having four sides, a top and bottom:
a)
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 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).
b)
Ventilation opening(s) shall be provided at floor level and shall have a total free area of not less
than ½ 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 shall be
at least two openings. The bottom of the openings shall be at floor level and the upper edge no more
than 5 inches (127mm) above the floor. The openings shall be equally sized, spaced at 180 degrees
(3.14 rad) and unobstructed.
c)
Every opening shall have minimum dimensions so as to permit the entrance of a 1/8 inch (3.2mm)
diameter rod.
3.3.3
Cylinder valves shall be readily accessible for hand operation. A door on the enclosure to gain access
to the cylinder valve is acceptable, provided it is non-locking and can be opened without the use of
tools.
3.3.4
There shall be a minimum clearance of 2 inches
(50.8mm) between the lower surface of the floor
of the LP gas supply cylinder enclosure and the
ground.
3.3.5
The design of the enclosure shall be such that
(1) the LP gas supply cylinder(s) can be con-
nected, disconnected and the connections
inspected and tested outside the cylinder enclo-
sure; and (2) those connections which could be
disturbed when installing the cylinder(s) in the
enclosure can be leak tested inside the enclosure.
3.3.6
Be certain to mount or set the LP gas cylinder on a flat surface and restrain it to prevent it from tipping.
Purge the gas supply line of any trapped air prior to the first firing of the unit.
DURING THE INITIAL PURGING AND SUBSEQUENT LIGHTINGS, NEVER ALLOW GAS VALVE TO RE-
MAIN IN THE "OPEN" POSITION WITHOUT FIRST PLACING AND IGNITING THE FIRESTARTER.
