When using a stainless steel flexible gas connector, do not attach the connector nuts directly to the
gas pipe supply. Connector nuts must be installed to an approved adapter.

Connect the main gas supply line with an approved flexible connector or, if the authority having
jurisdiction requires rigid piping, the use of approved swing joints may be used. If swing joints are utilized,
the heater must be allowed to freely expand and contract without causing undue stress on the gas pipe.
The heater shall not be connected to the building piping system with rigid pipe or semi-rigid metallic
tubing, including copper. When using such material, an intermediate connection device that allows for the
heater expansion must be used.
The gas outlet must be in the same room as the appliance is installed, and must be accessible. It may not
be concealed within or run through any wall, floor or partition. When installing the heater in a corrosive
environment (or near corrosive substances), use a gas connector suitable for the environment. Do not use
the gas piping to electrically ground the heater.
Installation of the Gas Line to the Heater
1
Install a sediment trap / drip leg in the supply line at the lowest spot prior to the gas ball valve. The
trap length shall be at least 3 inches long. Ideally, the trap would be installed as close as possible to
the shut off. NOTE: For high pressure gas above 14” W.C., a high pressure regulator and ball valve
must be utilized and located upstream of the flex connector.
2
Install manual shut off ball valve with optional 1/8” NPT Test connection towards the supply line. The
manual shut off ball valve must be located within 6 feet of the appliance’s service access door.
3
Install the 5/8” flare to 1/2” NPT adapter piece downstream of the gas valve as shown in Figure 3.27.
This piece is typically included with the flexible gas connector, loosely installed on one of the flare
nuts. NOTE: Keep flare surfaces clean and free of sealing compounds. Only the pipe threads require
sealing compounds.
4
Form the stainless steel flexible connector into a smooth C-shape, allowing approximately 12 inches
between the flexible connector’s end nuts (see Figure 3.27). The connector must reach from the gas
supply to the appliance without stretching, kinking, or twisting.
5
Attach the flexible connector to the 5/8” flare adapter on the gas line and the other end to the 5/8”
flare on the heaters inlet pipe. DO NOT connect the connector flare nuts directly to pipe threads.
Use only the adapters provided. DO NOT kink, twist, or over-torque the connector when installing.
