Installing an outdoor wood furnace can be broken down simply.
However, we have a 49 page manual to explain and show every detail, so you can do it yourself, like over 80% of our customers!
- Pour a 4″ concrete pad (best option) or place cinder blocks partially buried, to support the furnace. It weighs 1600 lb. It will only take ½ yard of concrete for a 4′x10′ pad (approx 4″ thick). This gives you a nice place to stand and load wood.
- Dig a trench below the frost line (the maximum depth to which frost normally penetrates the soil during the winter), with a small backhoe (can be rented), to prevent excessive heat loss and freezing. The ground stays at a nice 45-55 degrees below this point. This depth varies from area to area depending on the climate. See the map below or call your local building inspector’s office.Trenchers or small excavators/backhoes can be rented cheaply allowing you to do this with little effort, avoiding a $40-60 an hour fee from your local landscaper or septic tank installer.You will be placing PEX pipe and a 12/3 110V wire in a 4-6? PVC pipe. The PVC pipe is placed in the trench, from the furnace to the house. We highly recommend that you use insulated Pex Pipe. This will save you a lot of wood. You can insulate the pipe yourself and run it through PVC pipe and save about 50% over pre-insulated pipe.
- Install the heat exchanger in the furnace’s outlet plenum. You can probably find a size to fit your plenum so that little or no metal work is needed. It is usually a slide-in affair with some L-shaped bracing to hold in in place. Just cut a hole the proper width in the side of the plenum (usually 4″), slide in place and reseal.
- Hook up the PEX pipe at both ends – the furnace and at the heat exchanger.
- Hook up the PEX pipe (a second run and pump is recommended) at the hot water heater. This also supplies water to your outside furnace, to fill it.No side-arm heat exchanger needed since potable hot water is circulated directly between the furnace and hot water heater! (See below) This saves you about $200.
- Install a circuit breaker ($8-20) in your breaker box and connect the 110V wire/cable to the breaker and furnace. (You wire up the back of the furnace including the light – which is shipped in the firebox, so it doesn’t get damaged.)
- Install a simple thermostat and hook up.
- Fill with water. Start a fire!
- You are now saving money every day!
