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 for your gas type or conversion kit.
INSTAllING GAS PIPING To FIRePlACe / BURNeR SYSTeM loCATIoN
All electric heaters have hot and arcing or sparking parts inside. Do not store or
use gasoline or other flammable vapors and liquids in the vicinity of this or any
other appliance.
INSTAllATION ITEMS NEEDED
Before installing fireplace and burner system, make sure you have the items listed below.
• External regulator (supplied by installer) •
Sealant (resistant to propane/LP gas)
Sediment trap (recommended)
• Tee joint
• 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 40. Pointing the vent down protects it from freezing rain or sleet.

• Test gauge connection*
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 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.
