Fig. 4 Typical gas line installation.
When using copper or flex connector, use only
approved fittings. Always provide a union when
using black iron pipe so the gas line can be easily
disconnected for burner or fan servicing. See gas
specifications for pressure details and ratings.
NOTE: If flex connector is used, it must be kept inside
of the heater.
Gas Supply Pressures
This heater must be isolated from the gas supply piping
system by closing its individual manual shut-off valve
during any pressure equal to or less than 1/2 psig
(3.45kPa).
The heater and its individual shut-off valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 psig (3.45kPa).
