Copper or internally tinned copper tubing can only be used according to the National Fuel Gas Code, section 2.6.3, providing gas meets sulfide limits, and where permitted by local codes. - Page 12 CONNECTING THE GAS The heater gas inlet connection is 3/8" NPT at the regulator, inlet on the right side facing the gas log. If a left side connection is required, the connecting pipe may be led under the rear of the gas logs or behind the grate for connection to the inlet. NOTE: The milli-volt valve has an internal regulator, thus the incoming gas line connects directly to the valve.
