Before connecting the black iron gas line to
the inside of the appliance a sediment trap
must be included outside the appliance be-
tween the gas line and the gas shutoff valve.
It must extend down 3" beyond the center of
the pipe. Prepare incoming black iron gas
line with Teflon tape or pipe joint compound
(Check with local building codes).
CAUTION: Compounds used
on threaded joints of gas piping
shall be resistant to the action
of Liquefied Petroleum (LP or
propane), and should be applied
lightly to ensure excess sealant
does not enter the gas line.
WARNING: All gas piping
and connections must be tested
for leaks after the installation is
completed.
After ensuring that the gas valve
is on, apply a noncorrosive leak
detection solution to all con-
nections and joints. If bubbles
appear, leaks can be detected
and corrected.
Do not use an open flame for leak
testing and do not operate any
appliance if a leak is detected.
Complete your gas installation by connect-
ing incoming gas line with flexible gas line.
Secure tightly with wrench but
DO NOT
OVERTIGHTEN.
