Linear Outdoor Fire (LOF)
If this Linear Outdoor Fire (LOF) is permanently connected
to a gas piping system from a remote supply tank, installa-
tion 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 cylinder- the enclosure must adhere to the fol-
lowing construction requirements:
• Enclosures may be constructed with one side
completely OPEN or if the enclosure is built with four
(4) sides, a top and a bottom, then as follows:
• A Propane/LP gas cylinder enclosure requires four
(4) ventilation openings at the top and bottom of the
enclosure. The openings must adhere to the minimum
requirements according to the capacity of the cylinder
(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,
unobstructed 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 minimum dimensions to allow
entrance of a 1/2” (3.2 mm) diameter rod.
• Ventilation openings in side walls must not communi-
cate directly with other enclosures of the Linear Out-
door Fire pit.
• The cylinder 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, disconnec-
tion and inspection of the connection of the LP gas
cylinder.
• The enclosure should allow testing of any connection
on the LP cylinder that might be disturbed during
installation.

Most Linear Outdoor Fire’s are equipped for Natural gas (NG) however, if you are considering converting
to LP gas use the guidelines below for proper tank storage.
