FIREPLACE INSTALLATION
CHECK GAS TYPE
Use proper gas type for the fireplace you are installing.
If you have conflicting gas type, do not install fireplace.
See dealer where you purchased the fireplace for proper
fireplace according to your gas type.
INSTALLING GAS PIPING TO FIREPLACE
LOCATION
A qualified installer or service person must
connect appliance to gas supply. Follow all
local codes.
INSTALLATION ITEMS NEEDED
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*
• 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 regulator
damage could occur. Install external regulator with the vent
pointing down as shown in Figure 50. Pointing the vent
down protects it from freezing rain or sleet.
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.

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.
