fireplace. See dealer where you purchased the fireplace for proper fireplace according to your gas
type.

Before installing stove and burner system, make sure you have the items listed below.
• External regulator • Piping (check local codes) • Sealant (resistant to propane/LP gas)
(supplied by installer) • Test gauge connection* • Sediment trap (recommended)
• Equipment shutoff valve* • Tee joint • Pipe wrench
• 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 con-
nection. 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 32. Pointing the vent down protects it from freezing rain or sleet.
