If this fire pit is permanently connected to a gas piping
system from a remote supply tank, installation must be in
accordance with local codes or, in absence of local codes,
with the National Fuel Gas codes ANSI Z223/1/NFPA 54.
If constructing an enclosure to conceal a propane tank/
•
LP cyclinder- the enclosure must adhere to the follow
-
ing construction requirements:
Enclosures may be constructed with one side
•
compeletely OPEN or if the enclosure is built with four
(4) sides, a top and a bottom, then as ollows:
A Propane/LP gas cyclinder enclosure requires four
•
(4) ventilation openings at the top and bottom of the
enclosure. The openings must adhere to the minumum
requirements according to the capacity of the cyclinder
(See diagram 1).
Each opening in the enclosure must be equally sized
•
and spaced at a minimum of 180º. Openings must
remain unobstructed.
Top ventilation openings are required on the side walls
•
of the enclosure within 5-inches (127mm) of the top
enclosure. They need to be of equal size,
unobstructive and spaced 180º apart. The openings
need to be a total area of 1 in² /lb (14.2 cm²/kg) of fuel
storage capacity.
Bottom opening must provide a minimum of 1/2 square
•
inches (3.23 cm²) for each pound of propane/LP
contained in the tank (see example below.
Every opening must have minmum dimensions to allow
•
entrance of a 1/2” (3.2 mm) diameter rod.
Ventilation openings in side walls must not connunicate
•
directly with other enclosures of the fire pit.
The cyclinder valve must be easily accessible by hand.
•
Connections should be easy to leak test inside the
enclosure. A door on the enclosure is acceptable only if
easily opened without the use of tools and is non
locking.
The enclosure needs to be isolate the cylinder from the
•
burner compartment and provide protection from
radiation, act as a flame barrier and protect cylinder
from foreign material.
The enclosure needs to allow connection, disconnection
•
and inspection of the connection of the LP gas cylinder.
The enclosure should allow testing of any connetion on
•
the LP cylinder that might be distrubed during
installation.
