INSTALLING GAS PIPING TO FIREPLACE
LOCATION
A qualifi ed installer or service person must
connect appliance to gas supply. Follow all
local codes.
INSTALLATION ITEMS NEEDED
Before installing fi replace 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 fl exible gas line with gas connector (if
allowed by local codes — not provided)
* A CSA design-certifi ed equipment shutoff valve with
1/8" NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA design-certifi ed 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
fi replace 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.

can be used per National Fuel Code, Section
2.6.3, providing gas meets hydrogen sulfi de
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 fl ow 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
fi re hazard.
When using copper or fl ex connectors use only fi ttings
