CAUTION
Ground supply lead must be connected to the wire attached to the green ground screw located on the outlet box. See Figure 45. Failure to do so will result in a potential safety hazard. The appliance must be electrically grounded in accordance with local codes or, in the absence of local codes, the National Electrical Code, ANSI/NFPA

*A Sediment Trap is recommended to prevent moisture and debris in gas line from damaging the valve.
Note:The gas supply line must be installed in accor- dance with building codes by a qualified installer approved and/or licensed as requed by the locality. In the Commonwealth of Massachusetts, installa- tion must be performed by a licensed plumber or gas fitter.

These appliances are equipped with a gas flex line for use (where permitted) in connecting the appliance to the gas line. A gas flex line is provided to aid in attaching the direct vent appliance to the gas supply. The gas flex line can only be used where local codes permit. See Figure 46 for flex line description. The flex line is rated for both natural gas and propane gas. A manual shut off valve is also provided with the flex line.
The incoming gas line should be piped into the valve compartment and connected (see Figures 46 & 47). The millivolt control valve has a 3/8" (10 mm) NPT thread inlet port. The electronic control valve has a 1/2" (13 mm) NPT thread inlet port and is fitted with a 1/2" x 3/8" (13 mm x 10 mm) NPT fitting.
Secure all joints tightly using appropriate tools and sealing compounds (ensure propane resistant compounds are used in propane applications).
