Always latch the doors securely. If the fire box door is open for any extended amount of time
past the normal loading period, it will cause over-firing of the unit and result in the overheating of
the unit. This will cause damage to the electrical equipment and will result in causing the unit to
boil over. Always remember to keep your hinges oiled.
Always use proper care when installing, operating and maintaining the furnace.
Always wear protective gloves and glasses and be aware that loose or hanging clothing can
catch fire!
Be careful when loading wood into the furnace. Surface areas inside the furnace are hot.
Creosote build up in the furnace can ignite suddenly or cause burns if dripped onto the skin.
Do not modify the furnace. Do not substitute repairs that can be provided by your dealer,
distributor or manufacturing company. Any such action will void your warranty.
Do not operate under pressure. This is a non-pressurized system. Addition of valves or plugs
to the system that would cause pressure will void your warranty.
Keep the overflow tube clean and free of debris, bugs, etc. DO NOT close it off! The tube is
meant to steam if necessary and allow for pressure release.
Failure to heed these warnings or any additional warnings on the furnace may result in an
accident causing personal injury and damage.
!! CALL LOCAL UTILITIES BEFORE YOU DIG THE TRENCH!!
Disposal of ashes:
ASHES SHOULD BE PLACED IN A METAL CONTAINER WITH A TIGHT-FITTING LID. THE
CLOSED CONTAINER OF ASHED SHOULD BE PLACED ON A NON-COMPUSTIBLE FLOOR
OR ON THE GROUND. ALL COMBUSTIBLE MATERIALS SHOULD BE DISPOSED OF BY
BURIAL IN SOIL OR OTHERWISE DISPERSED. ASHES SHOULD BE RETAINED IN THE
CLOSED CONTAINER UNTIL ALL CINDERS HAVE THOROUGHLY COOLED.
Installation, to include wiring and plumbing, and operation must follow Federal, Provincial, State
and Local Codes, electrical, plumbing, fire and building codes.
The Earth furnace is intended to be the primary source of heat. However, a back-up system
should always be in place and ready for use.
A back-up generator is HIGHLY recommended so that you can have heat during power outages!
The standard pump and fan draw 120 watts together. The furnace can draw 1350 watts or more
on start-up. A small 2000 watt generator will power it all and give you extra power for lights.
The manufacturer is not liable for damages or property in the case of misuse, improper installation
of equipment or for knowing state or local installation codes. Product owner assumes all
responsibility for this. This document is a general manual to aid in installation. We cannot
know all applicable codes in your area!
Improper use or failure to maintain the outdoor furnace unit may cause nuisance conditions.
Persons operating this outdoor furnace are responsible for operation of the unit so as not to
cause a public or private nuisance condition. The manufacturer’s distance and stack height
recommendations and the requirements in any applicable laws or other requirements may not
always be adequate to prevent nuisance conditions due to terrain or other factors.

GETTING TO KNOW YOUR FURNACE
COMMON QUESTIONS
IS IT SAFE?
Having the furnace outside eliminates the possibility of causing a fire in your home. The furnace is a
non-pressurized system which eliminates any chance of explosion associated with pressurized
furnaces. Also the oversize door makes loading easier.
WHAT CAN ISIT THE FURNACE ON?
A 4 to 6 inch concrete pad is recommended, whether preformed or poured.
HOW FAR AWAY CAN IT BE?
Earth Outdoor Wood Furnaces can be set from 30 to 300 feet away from your home. There are a
few things to keep in mind: 1. The ease of access for digging lines to your house from the furnace 2.
How you will get wood to your furnace 3. How far you want to go when needing to fill the furnace with
wood. 4. Check with your insurance company to make sure you are in compliance with your policy.
Normally you should visit your wood furnace twice a day to check the fire and fill with wood. You will
want to have easy access to this location with a truck or tractor to replenish the wood when needed.
HOW MUCH WOOD WILL IUSE?
That depends on your home, insulation and the quality of wood you're burning. This might help:
heating a 2,500 sq ft well-insulated home and a 60 gallon water tank with good wood could take
about 5 to 7 cords per cold season (6 months). The cost of a cord of wood these days is about
$120. You can see the savings of owning an Earth Furnace. That is $600 to $840 a year to heat
your home naturally with renewable energy. What did you spend last year?
WHAT DO IDO WHEN IGO AWAY FOR A COUPLE DAYS?
This is a common question. You have several options depending on your situation.
If your wood furnace is hooked up correctly, leave your pump on, your existing indoor furnace will
back heat the wood furnace preventing it from freezing. The cost of your indoor furnace back heating
your outdoor is very minimum cost if everything is very well insulated.
Here are a few more options for you:
1. You can set up your unit with a bypass to not heat the home and circulate the water
within itself and the burn time will be much longer--4 to 5 days.
2. If the weather isn't really cold the circulation pump is moving the water quite quickly.
Moving water is hard to freeze.

7
3. Maybe a friend or family member could help and feed the unit while you’re away.
4. You could look into special anti freeze. Keep in mind most anti freeze is terrible to our
environment and costly.
5. You can let the fire die down and drain the furnace. It only takes about 10-20 minutes to
drain the unit. When you return simply refill the unit and relight the fire.
6. "If there is a will there is away!"
WHAT IF THE ELECTRICITY GOES OUT?
The Earth Outdoor Wood Furnace uses very little electricity which can be supported by a small
generator. You can run a regular inexpensive extension cord to the unit and unplug the furnace from
the outlet on the back of the furnace and plug into a small generator. Problem solved. However, when
most homes lose electricity they have no way to power the indoor blower for their duct work. Either
way you will need something to back up your existing home as well as the wood furnace. Another
option would be to use an extension cord on a box style fan and place the fan so that it would blow
into the return vent of your duct work. Then close off the vents to rooms you can afford to let go
cold. Otherwise you will need to look into a system that will power your indoor blower. Consult
electrical contractors for most of that type of work.

HOW DOES IT WORK?
The fire chamber is completely immersed in a jacket of water (except for the front of the furnace at
the fill door). When a fire is built it heats the water and a pump takes the hot water to the house.
Inside the house you have some kind of heat transfer appliance; this can be a heat exchanger that
fits into your duct work, baseboard style heaters, or a radiant floor heating system. The water can
then be returned to the furnace for reheating. The hot water from the furnace can also be sent to a
special heat exchanger to heat your domestic hot water or copper coils of some type may have been
installed in your furnace depending on what options you had ordered with your furnace.
INSTALLATION
It is important that you have the furnace installed by a qualified installer. Earth Outdoor Wood
Furnaces will not be held responsible for complications due to improper installation and in some
cases the warranty may be voided due to improper installation and start up.
There can be many variations in proper installation. Here are some general guidelines to follow.
Setting the Furnace
Depending on your application and site conditions, you may choose a pre-poured pad or you may
choose to pour a concrete pad. Pad size will depend on customer preference. The smallest pad
recommended for the Klear Sky 400 should be no smaller than 4 ½ feet by 5 ½ feet. You may
choose to pour a larger one based on your own situation and preference.
Underground Line
When digging the trench, it is best to dig below the frost line. You will normally need two 1” lines for
the supply and return of the furnace water, one 1/2” line for the furnace fill line, and an electrical line
to power the furnace. Some installations may require more lines check with a qualified installer or
ask our customer service department to help.
Setting up the system
It is best if this system is set up in a continuous loop going from one appliance to another. Parallel
systems with tees will rarely work or will be inefficient in their movement of water.
There are a number of options and ideas on the set up of the whole furnace system. Consult some
one with experience to design a system that will work for you.

10
STARTING UP THE FURNACE
Make sure all the valves on the back of the furnace are closed and that the power is off.
Begin filling the furnace with water. Turn the manual fill valve on the front of the furnace to allow
water to flow into the furnace tank. You can work on other things while it is filling. Once the water
starts to flow out of the over flow, shut off the water with the manual fill valve.
Double check that all the fittings and connections throughout the system have been tightened or
secured. Then open the valve going to the pump and from the furnace. If you have a way to bleed
the air out of the system then open the bleed valve and turn the power on. (With a normal set up,
the pump coming out of an upper port and returning to a lower port, all you have to do is open the
ball valve on the top side of the pump and then open the drain valve on the lower port. The pump
has enough pressure to push air out of the lines, however, if you get water in the return lines prior to
pumping water from the furnace your line will become air locked and that will require special help
from another water source to fix.)
Once the pump has started pushing water through the lines, check the various connections
throughout the system to verify they are all good and you have no leaks. After the system has been
purged of air, close the bleeder valve and open the ball valve to the furnace on the return port.
Now it is time to start a fire. It is recommended that you check all the lines prior to starting a fire in
case you have a problem that needs to be repaired. It is easier to repair the lines while they are cold
than when you have hot water flowing through them. When first starting up the furnace, build a
manageable fire to get the water up to temperature. We recommend using a 40 lb. bag of natural
charcoal and propane torch to initially start the fire. Wait 15 to 20 minutes for a bed of coals to form,
and slowly add your seasoned cordwood as it burns, loading/stacking the wood towards the front of
the unit, and never stacking it over ¾ high as this would restrict air flow. Cordwood should be
approximately 22 inches in length. Anything longer will hinder air flow. Once the water has gotten to
your desired temperature setting then you can add wood to start normal operations. Water will come
out of the overflow as it expands.

11
MAINTENANCE
The front wood door has two “U” bolts that are adjustable. If you feel the door is not closing tightly or
may be too tight, loosen the bolts with the door open and tighten or loosen the bolts as necessary.
It is important that the water is checked daily, especially after the first start up. We also require that
you have your water tested to maintain proper ph and necessary chemicals for your water conditions.
At the end of the season it is important to have all necessary chemical in the water if you will be
leaving the furnace full of water over the summer. Earth will pay for the water test for the 1st 7 years
of ownership.
You should clean your ashes out at least once a week, and as needed. The ash and coal bed should
be no higher than the bottom of the unit’s door as it will interfere with the blower and airflow. A flat
shovel works well for this job. We recommend using a metal container of some kind to put the ashes
in when removing them. Rake coals to the back of the furnace, remove the ashes, and then rake
coals back towards the front of the unit. At the end of the season, be sure to completely clean the
ash box. Ashes combined with moisture are very corrosive and can eat through metal. Ash or coal
corrosion is NOT covered under warranty.
You may use a chimney cap with the furnace to keep rain out. It is recommended that you at least
cover the chimney during the summer months when the furnace is not in use to keep rain, birds and
other insects from getting in the furnace.
The light, pump, and blower can all be visually inspected and should only need replacing when they
quit working. They should last for several years however conditions are different at every site and
longevity may vary based on your climate and maintenance.
Periodically check that the combustion blower tube, flame baffle, and chimney are not restricted by
debris (creosote, ash, etc.), and that door seal provides air-tight seal when shut to ensure proper use
of air controls.

12
TROUBLE SHOOTING
SQUEALING PUMP
On initial start up if the pump is not primed with water it may squeal and can burn your pump out.
Make sure the ball valve to the pump is open and the water tank is full.
On occasion the pump may get a piece of debris in the impellers from the installation process. Shut
the ball valves off and remove the pump. Take a clean garden hose and spray water through the
impeller housing to wash out any debris. Then replace the pump and start it back up.
CAN I OPERATE THE FURNACE WITH DOOR OPEN
It is not recommended that you operate the furnace for very long with the door open. This will cause
your furnace to over heat.
WATER IS NOT GETTING HOT
Several things may contribute to this problem.
Check that the fire is getting enough air. Make sure there is not obstruction in the chimney or
in front of the blower hole.
Ashes may be built up too much in the fire chamber. Before you stoke the fire make sure you
take a shovel or some device and rake the coals towards the middle of the furnace. Ash build up
around the edges work to insulate the fire box from the fire and do not let it heat like it was designed
to.
You may be burning too much green wood. It takes a large amount of Btu’s to burn/boil off
the water in a green log. This makes the fire burn cooler than when you use seasoned wood.
Your water lines may not be insulated enough. If you have exposed lines, or lines that run through
uncontrolled environments you may look into insulating them or putting more insulation on them.
Insulation is key to your performance.
Your blower in the house will drop the water temperature as much as 20 degrees. If the
temperature of the furnace water is not above 150, it makes it real hard to recover temperature loss
when the blower is on. Try turning the blower off and work with the fire to recover heat in the water.

13
LINES NOT GETTING HOT BUT WATER IS HOT
The water is not moving to the house or through the house.
Make sure the return ball valve is open at the furnace and that all valves are open through
the house.
If you have a multi-speed pump try increasing the speed.
It could be that you have an air bubble stuck in the lines somewhere. Turn the pump off and
loosen the bottom flange bolts until water will run out. Shut off the ball valves to the pump and on the
return into the furnace. Take a garden hose from a house faucet to the furnace. Steal a washing
machine hose from inside the house and use it to hook to the furnace drain and the garden hose.
Turn the water on at the house and open the drain. This will allow water from the hose to move the
entire system and purge any air bubbles. It will also cause the water to spray from the bottom flange
of the pump and you get wet if not careful. Allow this to run for approx two minutes (time can be
based on length of run to the house and back). Shut the water off and close the drain. Tighten the
flange and open all valves.
LINES NOT GETTING HOT THROUGHOUT ENTIRE SYSTEM
If you have put a tee into the system then water may not be flowing through one of the appliances.
You may have to re-plumb the system so that there is a continuous loop from the furnace to the
house and back.
The pump may have reached its operating capacity. Try increasing the speed of a multi-speed pump
or getting a bigger pump.
HOT WATER HEATER SIDEARM NOT HEATING
The sidearm could be air locked or not plumbed properly. Find a way to bleed any air out of the
domestic side of the system at the highest point.
Please refer to your Klear Stak Model 150 Series Installation and User Guide
for electrical guidelines and instructions.
