TYPICAL 20 LP PROPANE GAS SUPPLY INSTALLATION
We strongly recommend that you use the Summit
®
Built-In
Tank Cabinet (#21280) for installations using a 20 lb LP cylinder, mounted remotely in
an “island” structure.
The Summit
®
Built-In Tank Cabinet is a CSA listed accessory for installing a remote
mounted 20 lb LP cylinder, in an “island” structure. Summit ® Built-In Tank Cabinet has
a hose and regulator assembly and gas connections, for connecting a remote mounted
LP cylinder to the Summit
®
Built-In gas grill. The hose and regulator is listed as a
required part of the CSA listed Summit
®
Built-In gas grill.
The Summit
®
Built-In Tank Cabinet also meets the requirements for venting, tank
retention and separation of the LP cylinder from a heat source as outlined in the ANSI
Standard for Outdoor Cooking Gas Appliances, Z21.58/CSA 1.6 for LP enclosures.
The Summit
®
Built-In Tank Cabinet has its own installation guide.
If you do not use the Summit
®
Built-In Tank Cabinet, you need to hire a licensed
contractor or licensed plumber and they need to follow the requirements described
in the ANSI Standard for Outdoor Cooking Gas Appliances, Z21.58/CSA 1.6 for LP
enclosures.
The requirements described in the Standard for Outdoor Cooking Gas Appliances,
Z21.58/CSA 1.6. are as follows;
A remote enclosure for an LP gas cylinder shall be ventilated by openings at both
the upper and lower levels of the cylinder. This shall be accomplished by one of the
following:
a). One side of the remote LP cylinder enclosure shall be completely open; or
b). If the remote LP cylinder enclosure is designed to have four sides, a top and a
bottom, ventilation is required for the remote LP cylinder enclosure;
1). There should be at least two ventilation openings, (a hole or group of
holes, for the purpose of ventilation) in the sidewalls of the island structure.
The openings should be located within 5 inches (127mm) of the top of the
enclosure. The ventilation openings should be equally sized and spaced at
a minimum of 90 degrees, and be unobstructed. The openings shall have
a total free open area of not less than 20 square inches. (This relates to 1
square inch of ventilation area, per pound of stored fuel capacity).
2). Ventilation openings (a hole or group of holes, for the purpose of ventilation)
should be provided at fl oor level. The ventilation openings should have a total
free area of not less than 10 square inches. (This relates to 1/2 square inch
of ventilation area, per pound of stored fuel capacity). There should be at
least two ventilation openings if the ventilation openings at fl oor level are in
the sidewall. The ventilation openings should be within 5 inches (127mm) of
the fl oor. The ventilation openings should be of equal size and be spaced at a
minimum of 90 degrees, and should be unobstructed.
3). The minimum size of the ventilation hole (s) should not be less than 1/4 inch.
4). The ventilation openings in the sidewalls should not allow venting into
the empty or “hollow” area of the “island”. If a gas leak should occur or
the LP cylinder should vent in the LP cylinder enclosure, the gas should
not be allowed to vent or migrate into the empty or “hollow” area of the
“island”. Ventilation openings in the sidewalls of the enclosure should only
communicate with the outside of the “island” structure, so that the gas can
dissipate outside of the “island” structure.
c). If the remote LP cylinder enclosure has four sides, a top and a bottom, and is
intended for installation in a built-in “island” enclosure;
1). At least one ventilation opening (a hole or group of holes, for the purpose
of ventilation) needs to be on one side of the enclosure that communicates
with the outside of the “island” structure. If a gas leak should occur or the
LP cylinder should vent in the LP cylinder enclosure, the gas should not be
allowed to vent or migrate into the empty or “hollow” area of the “island”.
Ventilation openings should only communicate with the outside of the “island”
structure, so that the gas can dissipate outside of the “island” structure. The
ventilation opening should be located within 5 inches (127mm) of the top of
the enclosure, and should have a total free area of 20 square inches. (This
relates to 1 square inch of ventilation area, per pound of stored fuel).
2). At least one ventilation opening (a hole or group of holes, for the purpose
of ventilation) needs to be on one side of the enclosure that communicates
with the outside of the “island” structure, at the bottom. If a gas leak should
occur or the LP cylinder should vent in the LP cylinder enclosure, the gas
should not be allowed to vent or migrate into the empty or “hollow” area of
the “island”. Ventilation openings should only communicate with the outside
of the “island” structure, so that the gas can dissipate outside of the “island”
structure. The ventilation opening should be located within 5 inches (127mm)
of the bottom of the enclosure, and should have a total free area of 10
square inches. (This relates to 1/4 square inch of ventilation area, per pound
of stored fuel).
3). The minimum size of the ventilation hole (s) should not be less than 1/4 inch
(6.35mm).
d). The remote LP cylinder enclosure should be constructed with non-combustible
materials. The remote LP cylinder enclosure should isolate the LP cylinder from the
burner compartment, so that it provides shielding from radiation, be a fl ame barrier
and provide protection from foreign material such as hot drippings.
e). There should be a minimum of 2 inches (50.8mm) between the ground and the fl oor
of the remote LP cylinder enclosure.
f). The LP cylinder valve should be readily accessible for hand operation. A door on the
remote LP cylinder enclosure to gain access to the LP cylinder valve is acceptable,
provided it is non-locking and can be opened without the use of tools.
TEST CONNECTIONS
All connections and joints must be thoroughly tested for leaks in accordance with local
codes and all listed procedures in the latest edition of the National Fuel Gas Code ANSI
Z223.1/NFPA 54.
ƽ DANGER
Do not use an open fl ame to check for gas leaks. Be sure
there are no sparks or open fl ames in the area while you
check for gas leaks. This will result in a fi re or explosion
which can cause serious bodily injury or death, and damage
to property.
