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)
•
Test gauge connection*
• Sediment trap (recommended)
•
Equipment shutoff valve*
•
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 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 39.
Pointing the vent down protects it from freezing rain or sleet.

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