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
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.
INSTALLATION ITEMS NEEDED
Before installing fireplace and burner system, make sure you have the items listed below.
• External regulator (supplied by installer) • Piping (check local codes)
• Equipment shutoff valve*
• Tee joint
• approved flexible gas line with gas connector (if allowed by local codes — not provided)
* A CSA design-certified equipment shutoff valve with
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 33. Pointing the vent down protects it from freezing rain or sleet.

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.
