IMPORTANT: Hold appliance firmly with a wrench to prevent movement when connecting to inlet piping.
Always use an external regulator for all propane/LPG gas logs only, to reduce the supply tank pressure to a maximum of
13" w.c. High pressure natural gas systems require a regulator to reduce supply pressure to 10" W.C.
Locations that the Pressure Tapping
Point May be Installed
NOTICE: A qualifi ed gas appliance installer must connect the appliance to the gas
supply. Consult all local codes before installation.
NOTICE
Use new black iron pipe, steel pipe, copper tubing, or internally tinned copper tubing.
Copper or internally tinned copper tubing can only according to the National Fuel Gas
Code, section 2.6.3, providing gas meets sulfi de limits, and where permitted by local
codes. Gas piping system must be sized to provide minimum inlet pressure at the
maximum fl ow rate (BTU/Hr). Undue pressure loss will occur if the pipe is too small.
A manual shutoff valve must be installed upstream of the appliance. Union tee and
plugged 1/8" NPT pressure tapping point should be installed upstream of the appliance.
See Figure 9.
CAUTION
Connecting directly to an
