INSTALLATION, GAS LINE
Installation of the Inglenook fireplace and the Inglenook gas log kit must conform to National Standards, NFPA 54 (natural gas) or NFPA 58 (propane). The installation of gas line and leak testing must conform to the National Fuel Gas Code ANSI Z223.1 (United States) and CAN/CGA B-149 (Canada) Installation Code and all local codes and gas supplier restrictions. The Inglenook fireplace has been tested and approved for installation using a (7/8" O.D. / 1/2" I.D.) Model #1650 N Dormont Flex Connector supplied with the unit. A licensed plumber will be required to install a gas line and a supply cut-off valve to the Inglenook fireplace. Purge air from the gas supply line before connection is made to the Inglenook fireplace. The shut-off connection between the gas line and the Inglenook gas logs will be installed similar to that shown in FIGURE 2. Do not install gas supply lines in chimneys, gas vents, dumb waiters, elevator shafts, clothes chutes, or other air ducts. Gas piping should be sloped ¼” for every 12 feet of horizontal run. The slope will run from the gas meter down to the Inglenook. Horizontal runs of gas piping require mechanical support every 10 feet by suitable gas pipe hangars or straps. Install drip leg traps where condensate might accumulate in the gas supply line. Verify local code requirements for sediment traps. Traps collect moisture and sediment that might otherwise block the Inglenook gas log orifices or valves. Blockages can prevent the gas log system from operating properly. Depending on the length of gas line installed from the gas company meter to the Inglenook gas control valve, different size piping is required. Check with the local gas company for requirements but NEVER use plastic or galvanized pipe. Always follow the flow direction marked on all gas line connectors. Once installation of the gas line is complete, the Inglenook fireplace damper setting should remain in the fully open position as shown in FIGURE 2.

PRESSURE TESTING
The Inglenook and its control valve are to be isolated from the gas supply piping system by closing its individual cut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ½ psig (3.5 kPa). If pressures above ½ psig (3.5 kPa) are present, the Inglenook and its gas valve must be disconnected from the gas supply piping during any pressure testing.
