Operational Procedures
At fist glance, you will notice that the S4868P firebox is very simple
and similar to other outdoor wood furnace fireboxes on the market.
However, that is where the similarities stop.
The S4868P combustion area has been designed to accept large
wood loads without flooding the combustion chamber with to much fuel
release or to much combustion air. The S4868P regulates the air/fuel
ratio to burn a hotter more efficient fire. We call our burning method the
wick-burn/air-shear design. The result of burning with this method al-
lows the S4868P to burn cleaner, hotter and more efficient than other
more common designs while maintaining a large firebox size. Large
firebox designs are appealing due to ones ability to cut wood larger,
saving valuable time preparing the winters fuel supply. Even though you
may be a veteran wood burner, we recommend that you study the fol-
lowing operational methods and adhere to them closely. Following the
set operational procedures will ensure that your furnace can do the
greatest amount of heating on the least amount of wood, and do it
cleanly.
A overview to burning the Spirit way
Filling the furnace with water
The Model S4868P furnace has a water capacity of approximately
320 gallons. It is recommended that you estimate the filling time before
starting in order to prevent overflow. This can be done by timing how
long it takes to fill a 1 gallon pail.
Example: 1 gallon in 15 seconds
15 seconds x 320 = 4800 seconds
4800 seconds / 60 = 80 minutes
IMPORTANT: It is recommended that a flushing is performed before fill-
ing the unit to remove any foreign materials that may have found their
way into the water reservoir.

12
Operational Procedures
Filling the furnace with water
STEP 1 : Remove float cap assembly to one
side of the float and vent tube.
STEP 2 : Insert a garden hose into the float
and vent tube. Be sure that the hose is not
kinked or water flow will be affected, chang-
ing the calculated fill time.
STEP 3 : When the furnace is approximately
1/2 full, add the approved Outdoor Wood
Furnace water treatment.
STEP 4 : Continue to fill until the water level
is approximately 1 inch below the bottom of
the vent tube. This will allow for expansion
of the warming water to the proper water
level when the furnace is fired.
STEP 5 : Open any valves and check all installed plumbing for leaks.
STEP 6 : Apply power to the pumps and allow circulation and mixing to
occur of the treated water
NOTE: If overflow occurs, drain excess water from rear at the reservoir drain
Proper water level is 3-1/2” out of the
Top of the float cap assembly
Water should not be allowed to drop below
2” from the top of float cap assembly.
These Measurements are at operational
temperatures(160-180 deg.)

13
Operational Procedures
Starting a fire in the furnace
STEP 1 : Perform the following pre-firing checks.
 Does the firebox door move freely and seal?
 Does the combustion fan operate?
 Is the furnace water level correct ?
 Is the flue free from obstructions?
 Are there any leaks?
 Is the blower damper flap able to move freely?
 Is the pump circulating properly?
STEP 2 : Place paper or cardboard in firebox
approximately 3/4 the way back.
STEP 3 : Place approximately 1 bushel of dry kindling on the front side of the paper
in a loose random fashion as shown.
Always open door slowly!
CAUTION! Hot surfaces.
Keep children away. Do not
touch during operation.
LOAD FUEL CAREFULLY OR DAMAGE MAY RESULT
NOTE: Establish a routine for firing techniques. Check daily for creosote build up un-
til experience shows how often cleaning is necessary. Have a clearly understood
plan to handle a runaway fire.

14
Operational Procedures
Starting a fire in the furnace (continued)
STEP 4 : Make sure the blower switch is in the off position. Light a piece of paper
on fire and throw it to the back of the furnace. Immediately turn the fan switch to the
on position for 3 seconds and then turn off. This ensures that the fire will make con-
tact with your starter fuel. Once the starter fuel has begun to burn, close the door
and immediately turn on the blower switch.

liquid to start or freshen up a fire!
!
Always open door slowly!
Burn dry seasoned wood only.
Store wood in dry covered area
outside of the require clearances
and out of the way of cleaning
and fueling the furnace. Estab-
lish a safe routine for fuel storage
and loading.

Operational Procedures
Loading the furnace with fuel
STEP 5 : Allow the kindling to burn down to a coal bed. Turn the blower
switch off and open door slowly. Push the coal bed to the rear 25% of the
firebox with a long handled shovel.
STEP 6 : Load fire wood just in side the door and rank as tightly as pos-
sible. Cut wood no longer than 36 inches. Longer cut wood will tempo-
rarily obstruct air flow and cost efficiency. Do not fill the firebox above
the indicated maximum load line.
STEP 7 : Shut the furnace door and turn the blower switch to the on po-
sition.

Always open door slowly!
NOTE: If firebox
becomes over-
filled, turn the

Operational Procedures
The burning cycle
Please learn and follow the cycle of combustion and re-fueling in the
S4868P furnace. Doing so will increase the life of your unit by reduced
emissions, increase efficiency and decrease the amount of ash removal.
The S4868P furnace burns its fuel charge in a
wick form. This effectively controls the amount of
air and fuel that are allowed to mix, thereby creat-
ing a cleaner burn with hotter firebox tempera-
tures. The greater the difference between the wa-
ter temperature and the firebox temperature, the
more heat transfer power is available. This
equates to quicker recovery times and shorter
burn cycles. Notice to the left how the wood
charge has been consumed from the back to the
front. This is an appropriate amount of coal bed to
start up the next fuel charge.
Carefully push the remaining coal bed from
the previous fuel charge to the rear 1/3 of the fire-
box with a long handled shovel.
NOTE: Be aware that the hotter the fire, the
less creosote that is deposited and that weekly
cleanings may be necessary during mild
weather, even though monthly cleaning may
be enough in the coldest months. A Small in-
tense is preferable to a small smoldering fire
to reduce the amount of creosote deposition.
Load the new fuel charge to the front of the fire-
box no higher than 3/4 up in the door frame. A
partial fuel charge is shown in the picture to the
left for educational purposes. Once you get to
know your furnaces demands, it would be good
practice to only load as much fuel as would be
needed to get you to the next convenient fueling
time.

17
Operational Procedures
Ash removal
Ash removal, when used at maximum capacity, will be at 7 to 10 day
intervals, depending on ash content of the fuel being burned. For most,
ash removal will be at 21 to 30 day intervals. Ash is removed when it
builds up in the rear of the furnace enough that it noticeably affects air
flow. This will be noticed in more emissions (smoke) and longer cycling
times. When the furnace is used at 50% capacity or less, some ash
should be left in the firebox rear to protect your unit from going out on an
extended period of cycling time. The extra ash helps to hold the coals
while combustion air is not present.
The following is the suggested method for ash removal.
Always use a metal container with a lid to hold ash.
!
STEP 1 : Pull or keep a small bed of
coals to the front of the firebox.
STEP 2 : Remove remaining ash using
the rear of the furnace as a back stop.
STEP 3 : Push the coal bed to the rear
of the firebox and reload with fuel.

18
Operational Procedures
Resetting the computer
Your S4868P furnace is equipped with a fail safe in the event that it should drop be-
low normal operating temperatures for a period of time. This would signify that there is
no heat being created in the firebox. The fail safe prevents the cold outside air from
blowing threw the firebox, helping to prevent a possible freeze up or wasting heat.
Follow these steps to reset the computer.
NOTE: All the required operating parameters are pre-set at the fac-
tory. Do Not try to alter these settings. Doing so may cause oper-
ating problems and will not be covered as a warranty item.
Press and hold these
two buttons (Down
arrow and SET) at the
same time for 1 sec-
ond to reset the com-
puter from a low alarm
(LA flashes intermit-
tently with the current
water temperature).
The blower will start
within 7 seconds.
OR
Disconnecting the power
for a couple of seconds
and turning it back on will
also reset the computer.
Power failures will not
change the settings within
or harm the computer.

Operational Procedures
Shutting down for the season
The following procedures should be taken to protect your investment
when not in operation for extended periods of time.
A. Scrape the inside of the firebox and flue clean of creosote and
ash build up and remove.
B. Spray down the inside of the firebox and flue with vegetable oil.
Do not use motor oil.
C. Cap the top of any chimney or the flue to prevent moisture
from entering the firebox.
D. Disconnect the power to the unit.
E. Check all caulk seam and gasket and repair as needed.
F. Make sure the water reservoir is full to prevent corrosion.
G. Draw a cool water sample before shutting down the pumps and
forward to the testing lab in the sample bottle provided with the
approved treatment. Follow the recommendations of the lab
for corrections, if any.
Water conditioning
NOTE: Running your pumps during the off season for a period of 24
hours every other week will help keep pump seals from drying out.

Maintenance
While in use
1. Periodically inspect vent and
float tube for freeness.
2. Remove ash and scrape firebox
free of build up as needed.
3. Check water level daily.
4. Check door for air tightness.
The door gasket may display
dark hard areas where leaks are
present.
5. Ensure shields and access pan-
els are in place at all times.
6. Watch for damp areas inside the
firebox. This could signify a
leak. Condensation during the
first fire or while burning un-
seasoned wood during warmer
weather may also be present.
Only burn seasoned wood and
clean out damp ashes immedi-
ately.
After use (seasonal)
1. Thoroughly clean the furnace of
any creosote and ash. This is
the easiest to do when the fur-
nace is still warm.
2. Check all parts of the furnace for
any standing moisture.
3. Coat the inside of the firebox and
flue with vegetable oil when
clean and dry. Do not use mo-
tor oil!
4. Be sure the furnace reservoir is
to the maximum fill point.
5. Periodically circulate water dur-
ing the off-season to keep the
treatment mixed thoroughly and
lubricate pumps. Circulate for 24
hours once every other week.
6. Cap chimney or flue to prevent
moisture from entering the fire-
box.
7. If needed, thoroughly clean the
blower and flapper assembly.
Use the following procedure out-
lined on page to check for cor-
rect operation of the flapper as-
sembly.
