•  Refer to the piping chart at the bottom of previous page.

•  The corrugated gas line from the manifold is 58 inches 

long. Do not extend the gas line. 

•  We have provided the means to make an SAE 45° flare 

connection. Do not use pipe sealant on this connection.

•  If the length of line required does not exceed 50 feet, 

use a 5/8” O.D. tube. One size larger should be used for 

lengths greater than 50 feet. Refer to piping chart.

•  Gas piping may be copper tubing, type K or L; polyethyl-

ene plastic tube, with a minimum wall thickness of .062 

inch; or standard weight (schedule 40) steel or wrought 

iron pipe.

•  Copper tubing must be tin-lined if the gas contains more 

than 0.3 grams of hydrogen sulfide per 100 cubic feet of 

gas. 

•  Plastic tubing is suitable only for outdoor, underground 

use.

•  Gas piping in contact with earth, or any other material 

which may corrode the piping, must be protected against 

corrosion in an approved manner.

•  Underground piping must have a minimum of 18” cover.

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

We strongly recommend that you use the Summit

®

 Built-In 

Tank Cabinet (#21280) for installations using a 20 lb LP cylin-

der, mounted remotely in an “island” structure.

The Summit

®

 Built-In Tank Cabinet is a CSA listed acces-

sory 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 require-

ments 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.

GAS SUPPLY

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 ventila-

tion) in the sidewalls of the enclosure. 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 floor 

level. The ventilation openings should have a total 

free area of not less than 10 square inches. (This 

relates to  square of ventilation area, per pound of 

stored fuel capacity). There should be at least two 

ventilation openings if the ventilation openings at floor 

level are in the sidewall. The ventilation openings 

should be within 5 inches (127mm) of the floor. 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  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;
