Gas Piping Instructions - Southern Pride BBR 79-2 Instruction Manual

GAS PIPING INSTRUCTIONS

1.
READ ALL GAS PIPING INSTRUCTIONS CAREFULLY BEFORE MAKING GAS CONNECTIONS.
WARNING:
IMPROPER GAS HOOKUP WILL VOID WARRANTY AND COULD RESULT
IN HAZARDOUS CONDITION.
2. Connect the gas line to the 1/2 inch piping that extends from the Gas Burner. A 1/2
inch N.P.T. fitting is required.
NOTE: All piping must comply with local codes and ordinances of the National Gas
Code ANSI Z 223.1 - and NFPA #54.
3. The gas line should be a separate supply directly from the meter to the Burner. It is
recommended that a new pipe be used and located so that a minimum amount of work will
be required in future servicing. The piping should be so installed as to be durable,
substantial, and gas tight. It should be free from cutting burrs and defects in structure
and threading. Cast iron fittings or aluminum tubing should not be used for the main gas
circuit. Joint compounds (pipe dope) should be used sparingly on male threads only
and be approved for all gases.
NOTE: The building structure should not be weakened by installation of the gas piping.
The piping should not be supported by other piping, but should be firmly
supported by pipe hooks, straps, bands, or hangers. Butt or lap welded pipe
should not be bent.
4. The Pipe Capacity Chart must be used to determine the size pipe to use from the
meter to the Burner.

5. TEST PIPING FOR LEAKS. Before turning gas under pressure into piping, all openings
from which gas can escape must be closed. Immediately after turning on gas, the system
should be checked for leaks. This can be done by watching the 1/2 cubic foot test
dial for 5 minutes to show any movement, or by soaping each pipe connection and watching
for bubbles. If a leak is found, make the necessary repairs and repeat the above test.
NOTE: Defective pipes or fittings should be replaced and not repaired. Never use a
flame or fire of any form to locate gas leaks; use a soap solution.
6. After the piping and meter have been checked completely, PURGE THE SYSTEM OF
AIR. DO NOT bleed the air inside the unit. Be sure to relight all the gas pilots on other
appliances.
NOTE: The burner and its individual shutoff valve must be disconnected from the gas
supply piping system during any pressure testing at excess of 1/2 psig.
