Before installing fireplace and burner system, make sure you have the items listed below.
•
External regulator
(supplied by installer)
•
Equipment shutoff valve*
•
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 33. Pointing the vent down protects it from freezing rain or sleet.

•
Pipe wrench
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.
external regulators may be necessary for
natural gas. one- or two-pound systems
will damage this appliance and may cause
fire hazard.
When using copper or flex connectors use only fittings
approved for gas connections. The gas control inlet is
3/8" NPT.
