Installing gas piping to fireplace / burner system location

WARNING	A qualified installer or service person
	must connect appliance to gas supply.
	Follow all local codes.
installation items needed

CAUTION

For propane/LP units, never connect fireplace directly to the propane/LP supply. This burner system requires an external regulator (not supplied). Install the external regulator between the burner system and propane/LP supply.

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 28. 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
CAUTION	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.
