MATERIAL BEING ADDED REGULARLY

If you have any technical questions or need any help whatsoever, please call Billy or Ray at the factory.

Installing an outdoor wood furnace can be broken down simply*.

However, we have a 59 page manual to explain and show every detail, so you can do it yourself, like over 90% of our customers!

  1. 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.
     
  2. 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 this map 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 insulated 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.
     
  3. 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.
     
  4. Hook up the PEX pipe at both ends - the furnace and at the heat exchanger.
     
  5. 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. See this page 

    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.
     
  6. 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.)
     
  7. Install a simple thermostat and hook up.
     
  8. Fill with water. Start a fire!
     
  9. You are now saving money every day!

Backup Power for your outdoor wood furnace

We sell a battery charger and inverter combo that is easy to install and use!

Utility Power -When stove sentry is used with a 90 A-HR Marine Battery, its highly efficient circuitry can provide up to 8 hours of operation in the absence of electricity.

How it Works:

When electricity is present the Surefire Stove Sentry charges a battery and surveys the power line. At the instant that a power failure occurs, the Surefire Stove Sentry converts the energy stored in the battery to AC power. This assures operation of the wood furnace or pellet stove without interruption during the absence of electricity.

       

When AC utility power is restored, the Surefire Stove Sentry reinstates AC utility power as the prime energy source to operate the wood furnace or pellet stove. Simultaneously and automatically the Surefire Stove Sentry commences the recharging of the battery, to return it to full capacity in preparation for the next power failure.

You can also install a small solar panel to charge the battery, instead of using line power and use a less expensive inverter.

Bear in mind that you may also need a power supply (backup) for your furnace fan! A small generator will do the trick.

Hooking up the Hot Water Heater

You can heat all the hot water you need and store it in your existing hot water tank, just like you water heater does no, except that it will be free heat! This will save most people $35-$65 a month!

Simply put, you mount a pump on your hot water heater, to pump the cool water out of the hot water heater, through the standard built-in coil in our furnace and back to the hot water heater, all heated up.

This is much better than having an external heat exchanger because you also have to buy a tempering valve, so that you don't end up with scalding water. This is true with either the Side-Arm heat exchanger or plate exchanger; both of which are used externally.

Our system is much faster and more efficient because we have a pump pumping the water instead of the water slowly percolating through the heat exchanger through the difference in water temperature and pressure. That is a slow and inefficient process.

Installation: With an electric hot water heater, we recommend that you remove the pop-up valve and replace it with a 3/4" nipple (can vary) and a T for your incoming water. Put the pop-up valve back on one side of the T and the circulating pump on the other.

Remove the drain and do the same, putting in a T with the drain on one side and the outgoing water (Pex Pipe) on the other.

Put a surface mount thermostat beside, above or below the bottom element. About $10 at your local hardware store. The thermostat controls the pump, so that you don't have scalding water ever. Wire it so that 110V goes to one side of the thermostat ( which acts as an on-off switch) and the other side is wired to the pump. Common goes straight to the pump, as well as a ground wire.

You just saved up to $300 for a side-arm heat exchanger (or plate exchanger) plus at tempering  valve! You can still use the heater as normal. Simply turn the thermostat down lower on the hot water heater than on the thermostat just installed or turn off your breaker.

Be sure to click on lower right of diagram after downloading, to make it bigger.
 

Alternatively, you can run the incoming (hot) Pex pipe to a brazed plate heat exchanger for your hot water heater – before running to your heat exchanger for your furnace. It is usually about $175 plus about $110 for a tempering valve, to control the water temperature (to prevent scalding). In this case, you would only need 3 Pex lines running to your house, which may save a little money, if the furnace is going to be a long distance away. 

The downside is that your pump on the
furnace would have to run continuously (24/7), instead of cycling on and off as needed. They don't use a lot of electricity (about 80 watts) but it is increased wear and tear. Eliminating our built-in water coil reduces the cost of the furnace by $100. Our system is a LOT better because you have accurate temperature control. You don’t end up with scalding water as is possible with the external plate HE or side-arm.  

Gas Hot Water Heater

For a gas heater, there is usually a plate than can be removed to gain access to the tank itself (or cut an access hole). Simply mount the thermostat on the tank and follow the other instructions for water hookup above.

Our parts supplier offers a 15% discount to Shaver furnace customers, making the price of the Pex pipe only $5.39 a foot.

 These prices are plus shipping.

Note: The Pex pipe fittings we use are simple, push-on-by-hand Pex fittings

In addition to these parts, you will need to buy these parts locally:

12/3 UG wire

cement for the pad or solid concrete pavers/blocks

inexpensive 2-wire thermostat ($15)

 

Assuming that the furnace is going to be 50 feet from your home, you are looking at approx $325 for the parts 1-5 plus the Pex Pipe ($338 + shipping), if you want pre-made, pre-insulated pipe that you simply drop in the ground and cover up.

Chimney height relative to nearest downwind neighbor

1. If located 50 feet or less to any residence not served by the furnace, it is recommended that the stack be at least 2 feet higher than the eave line of that residence.

2. If located more than 50 feet but no more than 100 feet to any residence, it is recommended that the stack be at least 75% of the height of the eave line of that residence, plus an additional 2 feet.

3. If located more than 100 feet but no more than 150 feet to any residence, it is recommended that the stack be at least 50% of the eave line of that residence, plus an additional 2 feet.

4. If located more than 150 feet but no more than 200 feet to any residence, it is recommended that the stack be at least 25% of the height of the eave line of that residence, plus an additional 2 feet.

The chimney can easily be extended with standard stove pipe (with an adapter, for at NO CHARGE because we delete the cap), to any height necessary, with zero adverse affect on performance.

* Some building codes may allow a homeowner to be their own contractor and do much of the work themselves. In other locales a licensed electrician and plumber may be required to do the actual hookup.
This usually doesn't preclude you from putting in the
concrete pad, trench, pipe and wiring.
