WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
Do not use matches, candles, fl ame or
other sources of ignition to check for
gas leaks.

CAUTION
Some soap used for leak testing is
corrosive to certain types of metals.
Clean all piping thoroughly after
completing the leak check.
2-10
(located at the end of the supplied gas train) from the gas supply piping
system during any pressure testing of the system at pressures in excess of
2.0 psig (55 inch W.C.).
5. Gas Piping must be installed in accordance with National Fuel Gas Code,
ANSI Z223.1 1991 or latest addenda and any other local codes, which may
apply.
6. The pipe and the fi ttings used must be new and free of dirt or other
deposits.
7. Piping must be of the proper size to ensure adequate gas supply. A drip leg
and union connection must be installed upstream of the gas safety shut off
valves and must be a 5 inch (127 mm) minimum length.
8. Connect gas supply line to the open end of the tee on which the drip leg is
installed.
9. When making gas-piping joints, use a sealing compound resistant to
liquefi ed petroleum gases. Do not use Tefl on tape on gas line threads.
10. After gas piping is completed and before wiring installation is started,
carefully check all piping connections, (factory and fi eld), for gas leaks. Use a
soap and water solution.
11. The boiler must be disconnected at the boiler shut off valve from the gas
supply piping system during any pressure testing of the system.

NOTE: In cases where a vent line connection must be used on the gas
pressure regulator must be piped to outdoor air by the installer in
accordance with the National Fuel Gas Code, ANSI Z223.1-1991 or latest
addenda. In Canada gas installations must by in accordance with the current
CAN/CSA B149.1 and 2 and/or local codes.
 Components Requiring Ventilation to the Outdoors
The following do not require ventilation to the outdoors, as there is a vent limiter
in use:

Gas valve on the main fuel train

Lock-up regulator on the main fuel train

Regulator on the ignition enrichment line
An authority having jurisdiction may not permit the use of a vent limiter. In this
case, please use the following general guidelines:

A parts kit must be ordered from your Fulton manufacturer's representative
for plumbing the vent lines outside the cabinet. Improper plumbing will
cause the cabinet to lose its sealing, which can lead to improper combustion
and bypassing of the air fi lter. Instructions are included in the kit.

Start with the vent and cabinet bulkhead size, and as soon as is practical
increase the pipe size one diameter.
