Before installing fireplace and burner system, make sure
you have the items listed below.
•
External regulator
•
Tee joint
•
Equipment shutoff valve*
•
Sediment trap (recommended)
•
Piping (check local codes)
•
Sealant (resistant to propane/LP gas)
(supplied by installer)
•
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 equip-
ment 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 regula-
tor damage could occur. Install external regulator with the
vent pointing down as shown in Figure 42. 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.
