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 con-
version kit.

Before installing fireplace and burner system, make sure you have the items listed below.
• External regulator (supplied by installer) • Piping (check local codes)
• Sealant (resistant to propane/LP gas) • Test gauge connection*
• Sediment trap (recommended) • Pipe wrench
• Tee joint • Equipment shutoff valve*
• 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 28. Pointing the vent down protects it from freezing rain or sleet.
