Make sure you have the items listed below before installing appliance.
• External regulator (supplied by installer) • Piping (check local codes) • Test gauge connection*
• Sealant (resistant to propane/LP gas) • Sediment trap (optional but 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 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 wa-
ter. 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 14. Pointing the vent down protects it from freezing
rain or sleet.

limits, and where permitted by local codes.

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.
When using copper or flex connectors use only fittings
approved for gas connections. The gas control inlet is
3/8" NPT.
