FIREPLACE INSTALLATION
CHECK GAS TYPE
Use proper gas type for the fireplace you are installing. If you have conflicting gas type, do not install fireplace. See dealer where
you purchased the fireplace for proper fireplace for your gas type or conversion kit.

INSTALLING GAS PIPING TO FIREPLACE / BURNER SYSTEM LOCATION
INSTALLATION ITEMS NEEDED
Before installing fireplace and burner system, make sure you have the items listed below.
• External regulator (supplied by installer)
• External regulator (supplied by installer)
• Piping (check local codes)
• Sealant (resistant to propane/LP gas)
• Equipment shutoff valve*
• Test gauge connection*
• Sediment trap (recommended)
• Tee joint
• Pipe wrench
•

WC. 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

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.
