INSTALLING GAS PIPING TO FIREPLACE /
BURNER SYSTEM LOCATION
INSTALLATION ITEMS NEEDED
Before installing fi replace and burner system, make sure
you have the items listed below.
• Test gauge connection* • Tee joint
• Equipment shutoff valve* • Pipe wrench
• Sediment trap (recommended)
• External regulator (supplied by installer)
• Piping (check local codes)
• Sealant (resistant to propane/LP gas)
• 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 connec-
tion. Purchase the CSA design-certifi ed 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 27. Pointing the vent
down protects it from freezing rain or sleet.
WARNING
A qualifi ed installer or service person
must connect appliance to gas supply.
Follow all local codes.
CAUTION
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.
