FIREPLACE INSTALLATION
CHECK GAS TYPE
Use proper gas type for the replace you are installing.
If you have conicting gas type, do not install replace.
See dealer where you purchased the replace for proper
replace according to your gas type.
INSTALLING GAS PIPING TO FIREPLACE
LOCATION
When using copper or ex connectors use only ttings
approved for gas connections. The gas control inlet is
3/8" NPT.
CAUTION
For propane/LP units, never connect
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.
INSTALLATION ITEMS NEEDED
Before installing replace and burner system, make sure
you have the items listed below.
• External regulator • Tee joint
• Piping (check local codes) • Pipe wrench
• Sealant (resistant to propane/LP gas)
(supplied by installer)
• Test gauge connection*
• Sediment trap (recommended)
• Equipment shutoff valve*
• approved exible gas line with gas connector (if
allowed by local codes — not provided)
* A CSA design-certied equipment shutoff valve with
1/8" NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA design-certied 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.
CAUTION
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 sulde
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 ow rate (BTU/hr). Undue
pressure loss will occur if the pipe is too
small.
