If you have conflicting gas types, do not install fireplace. See dealer where you purchased the fireplace for proper fireplace for your gas type. INSTALLING GAS PIPING TO FIREPLACE LOCATION INSTALLATION ITEMS NEEDED Before installing, make sure you have the items listed below: • External regulator (supplied by installer) • Tee Joint • Piping (check local codes) • Pipe wrench • Sealant (resistant to propane/LP gas) • Test gauge connection* • Sediment trap (optional but recommended) • Approved flexible gas line with gas connector (if allowed by local codes - not provided) *A CSA design-certified equipment shutoff valve with 1/8” NPT tap is an acceptable alternative to test gauge connection. Purchase the CSA design-certified equipment shutoff valve from your dealer. For propane/LP connections only, the installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 13 inches of water. If you do not reduce incoming gas pressure, burner system regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 14. Pointing the vent down protects it from freezing rain or sleet. When using copper or flex connectors use only fittings approved for gas connections. The gas control inlet is 3/8” NPT. WARNING A qualified installer or service person must connect appliance to gas supply. Follow all local codes. CAUTION For propane/LP units, never connect fireplace directly to the propane/LP supply. This burner system requires an external regulator (not supplied). Install the external regulator between the burner system and propane/LP supply. ................................................ CAUTION Use only new black iron or steel pipe. Internally tinned copper or copper tubing can be used per National Fuel Code, section 2.6.3, providing gas meets hydrogen sulfide limits, and where permitted by local codes. Gas piping system must be sized to provide minimum inlet pressure (listed on data plate) at the maximum flow rate (BTU/hr). Undue pressure loss will occur if the pipe is too small. 100 gal. (min) Propane/ LP Supply Tank External Regulator Vent Pointing Down WARNING External regulators may be necessary for natural gas. One- or two-pound systems will damage this appliance and may cause fire hazard. FP1977 Figure 14 - External Regulator with Vent Pointing Down (Propane/ LP Only) FIREPLACE INSTALLATION WARNING CAUTION A manual shut-off valve must be installed upstream of the appliance. Union tee and plugged 1/8” NPT pressure tapping point should be installed upstream of the appliance. Figure 17 Only persons licensed to work with gas piping may make the necessary gas connections to this appliance. NOTE: The gas line connection may be made using 1/2” rigid tubing or an approved flex connector. Since some municipalities have additional local codes, it is always best to consult your local authorities and the current edition of the National Fuel Gas Code ANSI Z223.1/NFPA 54. In Canada CSA-B149 (1 or 2) Installation Code. A listed manual shut-off valve must be installed upstream of the appliance. Union tee and plugged 1/8” NPT pressure tapping point should be installed upstream of the appliance. Figure 15 IMPORTANT: Install main gas valve (equipment shut-off valve) in an accessible locations. The main gas valve is for turning on or shutting off the gas to the fireplace. Check your building codes for any special requirements for locating equipment shut-off valve to fireplaces. Apply pipe joint sealant lightly to male threads. This will prevent excess sealant form going into pipe. Excess sealant in pipe could result in clogged burner system valves. We recommend that you install a sediment trap/drip leg in supply line as shown in Figure 15. Locate sediment trap/drip leg where it is within reach for cleaning. Install in piping system between fuel supply and burner system. Locate sediment trap/drip leg where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into the burner...
