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 according to your gas
type.

Make sure you have the items listed below before installing appliance.
•
External regulator (supplied by installer)
•
Sealant (resistant to propane/LP gas)
•
Tee joint
•
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.

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.

Test gauge connection*
use only new black iron or steel pipe. inter-
nally tinned copper or copper tubing can be
used per National Fuel Gas Code, Section
2.6.3, providing gas meets hydrogen sulfide
limits, and where permitted by local codes.
Gas piping system must be sized to provide
minimum inlet pressure (listed on data plate)
at the maximum flow rate (Btu/hr). undue
pressure loss will occur if the pipe is too
small.
When using copper or flex connectors use only fittings
approved for gas connections. The gas control inlet is
3/8" NPT.
