CAST IRON STOVE AND B-VENT BURNER SYSTEM INSTALLATION
Continued
INSTALLING GAS PIPING TO STOVE LOCATION
WARNING: A qualified installer or service person must connect burner system to gas supply. Follow all local codes.
CAUTION: For propane/LP units, never connect burner system 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 stove 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 |
• | tee joint |
• | pipe wrench |
• approved flexible gas line with gas connector (if allowed by lo- | |
| cal codes) (not provided) |
Installation must include an equipment shutoff valve, union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from burner system (see Figure 28).
Check your building codes for any special requirements for locating equipment shutoff valve to stoves.
Apply pipe joint sealant lightly to male NPT threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged burner system valves.
WARNING: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.

*A CSA
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 14 inches of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 27. Pointing the vent down protects it from freezing rain or sleet.
