CONNECTING THE GAS
NOTICE
CAUTION
NOTICE: A qualified gas appliance installer must connect the appliance to the gas supply. Consult all local codes before installation.
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 sulfide limits, and where permitted by local codes. Gas piping system must be sized to provide minimum inlet pressure at the maximum flow 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.

Connecting directly to an unregulated propane/LPG tank can cause an explosion.
Pipe
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.
