GAS SUPPLY REQUIREMENTS
CORRECT GAS PRESSURE AND PROPER GAS SUPPLY LINE SIZING IS IMPERATIVE TO THE SUCCESSFUL PERFORMANCE OF YOUR
MENDOTA GAS FIREPLACE INSERT. BE SURE THE GAS SUPPLIER OR PLUMBER CAREFULLY CHECKS FOR CORRECT GAS PRESSURE AND
GAS LINE SIZING WHEN INSTALLING THE FIREPLACE INSERT.
IT IS CRITICAL TO CAREFULLY CHECK FOR GAS LEAKS WHEN HOOKING UP THE FIREPLACE INSERT -- CHECK WITH SOAP & WATER
SOLUTION.
BE SURE TO INSTALL FLEX GAS LINE WITH BRASS-TO-BRASS FITTINGS TO PREVENT GAS LEAKS AT CONNECTIONS.
GAS SUPPLY PIPING MUST INCLUDE A DRIP LEG TO ELIMINATE THE POSSIBILITY OF CONTAMINANTS ENTERING THE GAS TRAIN.
ADHERE STRICTLY TO LOCAL AND NATIONAL CODES.
GAS SUPPLY LINE SIZING
The Mendota Gas Insert comes equipped with a 3/8" N.P.T. [1.O cm] inlet on the main gas valve. Gas supply piping
may enter the cabinet from either the left or right side.
The proper gas line diameter must be selected to run from the supply regulator to the Insert. Refer to the following
table for proper gas pipe diameters.

NOTE: Some areas allow copper tubing or galvanized pipe - check with local approval agencies and codes NEVER use plastic pipe.
GAS PRESSURE CHECKING REQUIREMENTS
A pressure tap for checking gas pressure is located on the main gas valve. A qualified installer should use this fitting for setting
the correct gas pressure during initial installation. [See Gas Pressure Chart Pg. 17].
If supply gas pressures exceed 1/2 PSIG [3.5KPA], the appliance must be isolated from its supply with an approved manual shut-
off cock. This manual shut-off cock must be closed during any supply line pressure testing. Check with your gas supplier or
plumber.
