Regency ULTIMATE U41FS-NG - Gas Connection; High Elevation; Log Installation

INSTALLATION
GAS CONNECTION
The gas connection is a 3/8" SAE 45° flare elbow
fitting and is easily accessible by removing the pedes¬
tal cover plate. The gas line can be rigid pipe or to
make installation easier, use a listed flexible connector
and manual shut-off valve if allowed by local building
codes. For minimum and maximum supply pressure
see the System Data table below.
NOTE: During any pressure testing of the gas
supply piping system that exceeds test pressures
of 1/2 psig, this appliance and its individual shut¬
off valve must be disconnected from the piping
system. If test pressures equal to or less than 1/2
psig are used then this appliance must be iso¬
lated from the piping system by closing its indi¬
vidual manual shut-off valve during the testing.
A1/8" NPT plugged tapping is provided on the gas
control valve. It is located near the outlet to the Main
Burner immediately upstream of the gas supply
connection to the appliance, and is easily accessible
for a test gauge connection (see diagram on page 10).
