Thermo- Siphon Method

Optional Water Coil

To install the optional hot water coil, Two holes will need to be drilled or cut into the side of the stove. There is a template for the hole location(s) that is included with the coil. Keep the holes above the firebricks and toward the back of the firebox. This location is best to not interfere with loading.

Thermo- Siphon Method

This is the simple and most economical method, however, the hot water tank must be no more than ten feet from the stove. The water inlet, where the pressure relief valve is located, must be higher than the top leg of the coil. The tank should be elevated, if necessary, to allow for proper thermo-siphon action (the method by which water will circulate automatically through the system).

Circulating Pump Method

This method is used when the water heater tank can not be located close enough to the stove for the Thermo- Siphon Method, or if the water tank is on a lower floor level than the stove. In addition to the circulating pump, you may want to add an aquastat to thermostatically control the pump. This is optional and not necessary if the pump is left run continuously. Another option would be a gate valve placed near the pump to control the rate of water flow.

Read and follow all of the instructions that are included with the coil.
