Gas Supply Requirements - Mendota DXV-60 Installation & Operating Instructions Manual

CORRECT GAS PRESSURE AND PROPER GAS SUPPLY LINE SIZING ARE IMPERATIVE TO THE SUCCESSFUL PERFORMANCE OF YOUR MENDOTA
GAS FIREPLACE. BE SURE THE GAS SUPPLIER OR PLUMBER CAREFULLY CHECKS FOR CORRECT GAS PRESSURE AND GAS LINE SIZING WHEN
INSTALLING THE FIREPLACE.
IT IS CRITICAL TO CAREFULLY CHECK FOR GAS LEAKS WHEN HOOKING UP THE FIREPLACE -- CHECK WITH SOAP & WATER SOLUTION.
BE SURE TO INSTALL "APPROVED" 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 FOR ENTIRE INSTALLATION.
GAS SUPPLY LINE SIZING
The Mendota Gas Fireplace comes equipped with a 3/8" N.P.T. (1.Ocm) inlet on the main gas valve. This may
be removed if a ½" flexible connector is used. Gas supply piping can enter the Fireplace cabinet from either the
left or right side.
Install an approved individual shut-off valve in supply line to the fireplace. The appliance and its individual
shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that sys-
tem at test pressures in excess of 1/2 PSIG (3.5 kPa).
The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off
valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 PSIG
(3.5 kPa).
The proper gas line diameter must be selected to run from the supply regulator to the Fireplace. Refer to the fol-
lowing table for proper gas pipe diameters. Strictly adhere to the correct pipe sizes.

NOTE: Some areas allow copper tubing or galvanized pipe - check with local approval agencies and codes NEVER use plastic pipe.
GAS PRESSURE CHECKING REQUIREMENTS
Inlet and manifold gas pressure checking taps are located on gas valve. (See FIGURE 2 PAGE 7) A qualified
installer should use these fittings for setting the correct gas pressure during initial installation.

GAS LEAK TEST REQUIREMENT: It is the responsibility of the installer/service person to assure that
each and every gas connection and supply tubings that are a part of this fireplace are leak proof. The quali-
fied/certified individual connecting the gas supply line, performing pressure tests or performing any service to
this fireplace is required to perform a THOROUGH LEAK TEST on ALL gas fittings that are a part of this ap-
pliance or the gas supply line connection using soap-water solution or a calibrated combustible gas detector.
