3.4.1 Gas Supply Requirements
NOTE: if Insert is to be operated with LP gas, see Chapter Natural Gas to LPG Conversion in this manual
before proceeding.
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 AND
WATER SOLUTION OR COMBUSTIBLE GAS SNIFFER.
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.
3.4.2 Gas Supply Line Sizing
A 48” X 3/8” SS flex supply line with a 3/8” male NPT end adapter is supplied in the manual packet with this Insert. The flex
supply line may enter the cabinet from either the left side opening or rear left opening (round opening with grommet).
Use the table, below, to determine the proper gas line diameter that must be installed to run from the supply regulator to the
end of the 48” SS flex supply line adapter. Refer to the following table for proper gas pipe diameters.
