tank use- please see HPC Product catalog, visit www.hpcfire.com or contact your HPC Dealer for details.
IMPORTANT:
Locate the hose out of pathways where people may trip over it or in areas where the hose may be
subject to accidental damage.
For an enclosure using an LP tank system, follow these recommended specifications:
You must follow local codes.
IMPORTANT:
The remote LP Tank / Enclosure should be a minimum of 36” from the fire pit.
One side of the enclosure shall be completely open; OR
For an enclosure having four sides, a top, and a bottom:
o
At least two ventilation openings shall be provided in the side walls of the enclosure, located within 5 in
(127mm) of the top of the enclosure, equally sized, spaced at a minimum of 180 degrees, and
unobstructed. The opening(s) shall have a total free area of not less than 1in
2
lb (14.2 cm
2
kg).
See Figure 1.
o
Ventilation opening(s) shall be provided at floor level of the enclosure and shall have a total free area of
not less than ½ in
2
/lb (7.1cm
2
/kg) of stored fuel capacity. 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 1 in (25.4mm) or less
from the floor level and the upper edge no more than 5 in (127mm) above the floor level. The openings
shall be equally sized, spaced at a minimum of 180 degrees and unobstructed. See Figure 1.
Every opening shall have minimum dimensions so as to permit the entrance of a 1/8 in (3.2mm) diameter rod.
Ventilation openings in sidewalls shall not communicate directly with other enclosures of the appliance.
The cylinder valve shall 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. Designs using
a cover to gain access to the cylinder and cylinder valve shall be provided with handles or equivalent at a
minimum of 180 degrees apart to facilitate lifting of the cover.
The enclosure for the LP-gas cylinder shall isolate the cylinder from the burner compartment to provide:
o
Shielding from radiation;
o
A flame barrier; and
o
Protection from foreign material.
There shall be a minimum clearance of 2 in (50.8mm) between the floor of the non-disposable LP-gas cylinder
enclosure and the ground.
The design of the enclosure shall be such that:
o
A non-disposable LP-gas cylinder can be connected, disconnected, and the connections inspected and
tested outside the cylinder enclosure; and
o
Those connections which could be disturbed when installing the cylinder in the enclosure can be leak
tested inside the enclosure.
