Install 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) | • Sealant (resistant to propane/LP gas) | |
• | Tee joint | • | Test gauge connection* |
• | Piping (check local codes) | • | Sediment trap (optional but recommended) |
•Pipe wrench
•approved flexible gas line with gas connector (if allowed by local codes — not provided)
*A CSA
For propane/LP connections only, the installer must supply an external regulator. The external regula- tor 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 41. Pointing the vent down protects it from freezing rain or sleet.
