Before installing fireplace and burner system, make sure you have the items listed below.
•
External regulator (supplied by installer)
•
Piping (check local codes)
•
Sealant (resistant to propane/LP gas)
•
Test gauge connection*
•
Sediment trap (recommended)
•
Pipe wrench
•
Tee joint
•
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 24.
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.
