GAS SUPPLY REQUIREMENTS

NOTE: IF INSERT IS TO BE OPERATED WITH LP GAS, SEE PAGE 34 BEFORE PROCEEDING.

CORRECT GAS PRESSURE AND PROPER GAS SUPPLY LINE SIZING IS IMPERATIVE TO THE SUCCESSFUL PERFORMANCE OF YOUR ENDOTA 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. [1.0 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. 21].

If supply gas pressures exceed 1/2 PSIG [3.5KPA], the appliance must be isolated from its supply with an approved ma-

nual shut-off cock. This manual shut-off cock must be closed during any supply line pressure testing. Check with your

gas supplier or plumber.

If the factory-built fireplace has no gas

access hole(s) provided, an access hole 1.5” or

less may be drilled through the lower sides or

bottom of the firebox in a proper workman- ship

like manner. This access hole must be

plugged with non-combustible insulation after the

gas supply line has been installed.
