INSTALLATION
If the unit 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
the propane cylinder, the enclosure must
adhere to the construction requirement
below.
Enclosures may be constructed with one
side completely open OR if the enclosure
is built with 4 sides, a top and a bottom:
•
A propane gas cylinder enclosure
requires 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 Figure 16).
•
Each opening in the enclosure must be
equally sized and spaced at a minimum
of 180. Openings must remain unob
-
structed.
•
Top ventilation openings are required on
the side walls of the enclosure within 5"
of the top of the enclosure. They need
to be of equal size, unobstructed and
spaced 180 apart. The openings need
to be a total area of 1 in²/lb (14.2 cm ²/
kg) of fuel storage capacity.
•
Bottom opening must provide a
minimum of 1/2 square inches for each
pound of propane contained in the tank
(see example below).
•
Every opening must have a minimum
dimensions to allow entrance of 1/8"
diameter rod.
•
Ventilation openings in side walls must
not communicate directly with other
enclosures of the appliance.
•
The cylinder valve must be easily ac
-
cessible by hand. Connections should
be easy to leak test inside the enclo
-
sure. A door on the enclosure is accept
-
able only if easily opened without the
use of tools and is nonlocking.
•
The enclosure needs to isolate the cylin
-
der 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 connec
-
tion, 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 installa
-
tion.
