D. Propane Gas Enclosures Guidelines
NOTE: The propane cylinder and regulator hose as-
sembly (not provided) must meet the following require-
ments stated in points 1, 2 & 3.
1. Constructed and marked in accordance with the U.S.
Department of Transportation (D.O.T.) specifications

transportation of dangerous goods and commission,
CAN/CSA-B339, as applicable.
2. Provided with listed overfilling device.
3. Provided with connection device compatible with

•
When constructing an enclosure to conceal a propane
tank cylinder, the enclosure must adhere to the following
construction requirements:
•
Enclosure may be constructed with one side completely
open or if the enclosure is built with four sides, a top and
a bottom, then as follows:
-
A propane gas cylinder enclosure requires four
ventilation openings at the top and bottom of the
enclosure (Figure 3.4). The openings must adhere to
the minimum requirements according to the capacity
of the cylinder. (Listed below)
-
Each opening of the enclosure must be equally sized
and spaced a minimum of 90° apart (see Figure 3.4).
Openings must remain unobstructed.
-
Top ventilation openings are required on the side
walls of the tank enclosure within five inches
(127 mm) of the top of the enclosure. They need to be
of equal size, unobstructed and spaced a minimum
of 90° apart. The openings need to be a total area
of 1 in

(Example: 1.0 in

-
Bottom opening must provide a minimum of 1/2
square inch (7.1 cm
contained in the tank. (Example: .05 in
tank=10 in
)

-
Every opening must have minimum dimensions to
allow entrance of a 1/8 in. (3.18 mm) diameter rod.
-
Ventilation openings in side walls must not
communicate directly with other enclosures of the
linear appliance.
-
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 isolate the cylinder from the
burner compartment and provide protection from
radiation, act as a flame barrier, and protect the
cylinder from foreign material.
-
The enclosure needs to allow connection,
disconnection, and inspection of the connection of
the propane gas cylinder.

-
The enclosure should allow testing of any connection
on the propane cylinder that might be disturbed
during installation.
-
Installation of ventilation as described above
is required on fixed piping installs (Natural and
Propane) in addition to propane cylinder enclosures.
-
There is also a propane tank kit (LPTK-ODPLAZA-L)
available for the starter framing kit (FK-ODPLAZA-
24S) if a remote tank is not desired. Propane tank
kit is only to be used with a single 24 inch starter pan
and framing kit. The above ventilation requirements
are still required.
-
If using a site constructed table, a frame may be built
to attach tank kit frame and must have a mechanism
to retain the cylinder to prevent tipping.
