Gas Piping

SECTION VI - Gas Piping

Gas Supply Piping Connection

The gas supply piping must be installed
in accordance to all applicable local,
state and national codes and utility
requirements.

1. Install a 1/2” NPT pipe union at the factory

supplied gas nipple, for ease of service.

2. Install a manual shutoff valve in the gas

supply piping as shown in Fig. 16. For
installations in Canada the installer must
tag and identify the main shutoff valve.

3. Install a sediment trap (drip leg) on the gas

supply line prior to connecting to the
PRESTIGE Solo gas train as shown in
Fig. 16.

4. Support the gas piping using hangers. Do

not support the piping by the unit or its
components.

5. Purge all air from the gas supply piping.

6. Before placing the PRESTIGE Solo into

operation, check and test all connections
for leaks.

Close the manual shutoff valve during
any pressure test with less than 13”w.c..

Disconnect the PRESTIGE Solo and
its gas valve from the gas supply piping
during any pressure test greater than
13”w.c..

Do not check for gas leaks with an open
flame. Use a gas detection device or bub-
ble test. Failure to check for gas leaks
can cause severe personal injury, death
or substantial property damage.

7. Use pipe dope compatible with natural and

propane gases. Apply sparingly only to the
male threads of pipe joints so that pipe
dope does not block gas flow.

Failure to apply pipe dope as detailed
above can result in severe personal
injury, death or substantial property
damage.

Use a two-wrench method of tightening
gas piping near the unit and its gas pip-
ing connection. Use one wrench to pre-
vent the boiler gas line connection from
turning and the second to tighten adja-
cent piping. Failure to support the boil-
er gas piping connection could damage
the gas line components.
