Use proper gas type for the replace you are installing. If you have conicting gas type, do not install
replace. See dealer where you purchased the replace for proper replace for your gas type or
conversion kit.

Before installing replace and burner system, make sure you have the items listed below.
• External regulator (supplied by installer) • Piping (check local codes) • Sealant (resistant to pro-
pane/LP gas) • Equipment shutoff valve* • Test gauge connection*
• Sediment trap (recommended)
• Tee joint • Pipe wrench
• approved exible gas line with gas connector (if allowed by local codes — not provided)
* A CSA design-certied equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA design-certi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 45. Pointing the vent down protects it from freezing rain or sleet.

When using copper of flex connectors use only fittings
approved for gas connections. The gas control inlet is
3/8" NPT.
