GAS SUPPLY REQUIREMENTS

Correct gas pressure and proper gas supply line sizing is 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 12” flexible connector kit including a manual shutoff ball valve. Gas

supply piping must enter the Fireplace cabinet from the right side.

The included manual shut-off valve meets Federal Codes. I required by local codes, install an additional manual shutoff

valve upstream of the fireplace’s manual shutoff valve. The appliance and its individual shut-off valve must be discon-

nected from the gas supply piping system during any pressure testing of that system at test pressures

in excess

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

of ½ PSIG

(3.5 kPa).

equal to or less than

A proper gas line diameter must be selected to run from the supply regulator to the Fireplace. Refer to the following table

for proper gas pipe diameters. Strictly adhere to the correct pipe sizes. If in doubt, use the next larger size.

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 1 on Page 10). A qualified installer

should use these fittings for setting the correct gas pressure during initial installation.

NOTE: DO NOT DAMAGE OR KINK THE FLEX CONNECTOR. CHECK FOR GAS LEAKS WITH SOAP AND WATER

SOLUTION.

NOTE: 3/8" FLEX OR RIGID PIPING MAY BE USED TO CONNECT GAS SUPPLY TO UNIT DEPENDING ON STATE

AND LOCAL CODES.

NOTE: BE SURE TO INSTALL FLEX GAS HOSE WITH BRASS-TO-BRASS FITTINGS TO PREVENT LEAKS AT

CONNECTION.

NOTE: THE HARD PLUMBING FITTING PROVIDED IS TO BE USED WITH INSTALLATIONS REQUIRING HARD

PLUMBING. IT MAY BE REMOVED IF THE FIREPLACE IS BEING INSTALLED WITH A FLEXIBLE

CONNECTOR.
