Use only the correct type of gas (natural or propane/LP). If your gas supply is not the correct gas type, do not install fireplace. See dealer where you purchased your fireplace for proper gas type fireplace or tro purchase gas conversion kit (see Accessories, page 31).
Installing Gas Piping to Fireplace Location
WARNING: A qualified service person must connect fireplace to gas supply. Follow all local codes.
CAUTION: For propane/LP units, never connect fireplace directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install theexternalregulatorbetweenthe fireplace and propane/LP supply.
Installation Items Needed
Before installing fireplace, make sure you have the items listed below.
•external regulator (supplied by installer)
•piping (check local codes)
•sealant (resistant to propane/LP gas)
•equipment shutoff valve *
•test gauge connection *
•sediment trap

*A CSA
For propane/LP connection only, installer must supply an external regulator. External regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11" and 14" of water. If you do not reduce incoming gas pressure, fireplace regulator damage could occur. Install external regulator with vent pointing down as shown in Figure 22. Pointing vent down protects it from freezing rain or sleet.
CAUTION: Use only new, black iron or steel pipe. Inter-
Installation must include an equipment shutoff valve, union and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from fireplace (see Figure 23).
