(supplied by installer)
•
approved
fl exible gas line with gas connector (if

* A CSA design-certifi ed equipment shutoff valve with
1/8" NPT tap is an acceptable alternative to test
gauge connection. Purchase the CSA design-certifi 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 regula-
tor damage could occur. Install external regulator with the
vent pointing down as shown in
Figure 51.
