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
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) • Sealant (resistant to propane/LP gas)
• Equipment shutoff valve* • Test gauge connection* • Sediment trap (recommended)
• Tee joint • Pipe wrench
• A pproved 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
WC. 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
32. Pointing the vent down protects it from freezing rain or sleet.

When using copper or flex connectors use only fittings approved
for gas connections. The gas control inlet is

" NPT.
A qualified installer or service person must
connect appliance to gas supply. Follow all
local codes.
WARNING
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.
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 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.
CAUTION
