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 / BURNER SYSTEM LOCATION
INSTALLATION ITEMS NEEDED
Before installing fireplace 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) • Equipment shutoff valve* • 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 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 13. Pointing the vent down protects it from freezing rain or sleet.

CAUTION
Use only new black iron or steel pipe.
Internally tinned copper or copper tubing
can be used per National Fuel 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.
