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 to1 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 1/2 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.

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.

If your, licensed contractor or licensed plumber, builds an LP cylinder enclosure following the guidelines in the ANSI Standard for Outdoor Cooking Gas Appliances,

Z21.58 CSA 1.6, you need to order kit number (#21287), which will contain the hose and regulator assembly, mounting bracket for the regulator, connection fi ttings and LP tank bracket for retaining the LP cylinder that must be used with the Summit® Built-In gas grill. The hose and regulator in the kit (#21287) is listed as part of the CSA listed Summit® Built-In gas grill.
