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 location

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.

installation items needed

Before installing fireplace and burner system, make sure you have the items listed below.

•	External regulator (supplied by installer)	•	Piping (check local codes)	•	Equipment shutoff valve*
•	Sealant (resistant to propane/LP gas)	•	Test gauge connection*	•	Sediment trap (recommended)
•	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 connec- tion. 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 29. Pointing the vent down protects it from freezing rain or sleet.
