test. (See Fig.10.) It is recommended that the ground joint union be
loosened before pressure testing. After all connections have been
made, purge the lines and check for leakage with regulated gas
supply pressure.
Install a sediment trap in the riser leading to the furnace. The trap
can be installed by connecting a tee to the riser leading from the
furnace. Connect a capped nipple into the lower end of the tee. The
capped nipple should extend below the level of the gas controls.
(See Fig. 10.)
Apply joint compound (pipe dope) sparingly and only to the male
threads of each joint. The compound must be resistant to the action
of propane gas.
Install an accessible manual shut-off valve upstream of the furnace
gas controls and within 72 in. of the furnace. A 1/8-in. NPT
plugged tapping is provided on the gas valve for test gage

connection. Installation of an additional 1/8-in. NPT plugged
tapping, accessible for test gage connection, installed immediately
upstream of the gas supply connection to the furnace and down-
stream of the manual shut-off valve, is not required. Place ground
joint union between the gas control manifold and the manual
shut-off valve.
Use the proper length of pipes to avoid stress on the gas
control manifold. A failure to follow this warning can cause
a gas leak resulting in a fire, explosion, personal injury, or
death.
