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 piping nipple, for ease of service.
2. Install the factory supplied manual shutoff
valve in the gas supply piping as shown in
Fig. 14. 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 CHAL-
LENGER gas train as shown in Fig. 14.
4. Support the gas piping using hangers. Do
not support the piping by the appliance or
its components.
5. Purge all air from the gas supply piping.
6. Before placing the CHALLENGER into
operation, check and test all piping connec-
tions for leaks.
- Close the manual shutoff valve during
any pressure test with less than 13”w.c.
[32 mbar].
- Disconnect the CHALLENGER and its
gas valve from the gas supply piping
during any pressure test greater than
13”w.c. [32 mbar].
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 joint compound compatible with
natural and propane gases. Apply sparing-
ly only to the male threads of pipe joints so
that pipe dope does not block gas flow.
Failure to apply pipe joint compound as
detailed above can result in severe per-
sonal injury, death or substantial prop-
erty damage.
Use a two-wrench method of tightening
gas piping near the appliance and its gas
piping connection. Use one wrench to
prevent the appliance gas line connec-
tion from turning and the second to
tighten adjacent piping. Failure to sup-
port the appliance gas piping connection
could damage the gas line components.
