• Gas supply line access holes are located at the top and left sides of the Control Box. Gas valve inlet accepts a 3/8" N.P.T. tting.
Correct gas line diameter must be used to assure proper operation and pressure.
• NOTE: A sediment trap, as per national fuel gas code, must be installed in the gas supply line no more than 6 feet from
the gas control valve to minimize the possibility of any loose scale or dirt within the gas supply line from entering the
control valve.
• DO NOT HARD PIPE GAS LINE TO VALVE. A method of disconnecting the valve from the gas line such as a union or are tting
must be provided to allow for repair or replacement of the gas valve.

Warning:
The access panel - including gasket, must be reinstalled after conversion / installation or ser-
vicing has been completed. Failure to do so will cause overheating and premature failure of the
