SAFETY NOTICE
The authority having jurisdiction (such as municipal building department, fire
department, fire prevention bureau, etc.) should be consulted before installation to
determine the need to obtain a permit.
If your Efel Stove is not properly installed, a house fire may result. For your
safety, follow the installation directions. Contact local building or fire officials
about restrictions and installation requirements in your area.
ENSURE THAT THIS MANUAL REMAINS WITH THE APPLIANCE AND IS
PASSED ON TO THE USER AFTER INSTALLATION.
DO NOT STORE OR USE GASOLINE OR OTHER FLAMMABLE VAPOURS AND
LIQUIDS IN THE VICINITY OF THIS OR ANY OTHER APPLIANCE.
WARNING:
Improper installation, adjustment, alteration, service or maintenance can cause
injury or property damage. Refer to this manual for assistance or consult a
qualified (experienced) installer.
SPECIAL NOTE:
Crazing of Porcelain Enamel:
Porcelain enamel, when heated to high temperature, is subject to crazing. Crazing is
a normal occurrence when enamel is exposed to high temperatures. Your enamel
finish will not be harmed nor will the function of the stove be impaired.
SPECIAL NOTE:
A barometric damper is recommended for installations of stoves in areas that may
have high winds, which can affect the draft. The installation must be only in units
with a newly constructed chimney, free of creosote deposits. The barometric damper
is an automatic device designed to regulate the draft in a heating appliance, which in
turn, stabilizes the chimney temperatures, lessening the potential of over-firing. Do
not place the barometric damper greater than 24 inches (610 mm) above the unit.
Excessive draft will lead to poor control of the burning rate and possible over-firing of
the stove and damage to the cast iron firebox. Most barometric dampers are
calibrated in inches of water column and can be set to draft requirements of -.03 to -
.08 inches (-7.5 to -20 Pa). It is recommended that the barometric dampers to be set
between -.05 and -.06 inches.
THE RECOMMENDED DRAFT REQUIREMENTS FOR EFEL STOVES IS NO LESS
THAN -.04 AND NO GREATER THAN -.08.
OPERATION OF YOUR STOVE WITH A DRAFT GREATER THAN -.08 CAN
POSSIBLY CAUSE DAMAGE TO THE STOVE AND VOID THE WARRANTY.

Standard Installation
1. Position the unit no closer than the minimum clearances to combustible
materials. Check that no overhead cross members in the ceiling or roof will be
cut. Reposition unit if necessary, being careful not to move closer than the
minimum clearances.
2. A non-combustible floor protector (hearth extension) must be installed under
the unit. The floor protector must extend a minimum of 16 inches (450 mm)
beyond the front and side doors and 8 inches (200 mm) beyond the left side.
The floor protector must be equivalent to 1/2 inch (9.5mm) with a k factor of at
least 0.84 Btu/inch°F
Determining Thickness Requirements of Alternate Floor Protection Materials
The following formula gives the means of determining thickness of alternate
materials:
k of the alternate material x thickness of = thickness of
k of the specified material specified material alternate material
For example common brick has a k value of 5.0. The following would
determine the thickness necessary:
5.0 x 1/2 inch = 3.0 inches of common brick
0.84
3. Mark the position of the required floor protector on the floor. Remove the unit
and install the floor protector.
4. Position the unit on the floor protector at the proper clearances.
5. Install a 6-inch diameter, minimum 24 MSG black or 26 MSG blued steel
connector pipe on the flue collar of the unit.
•The stove is NOT to be connected to any air distribution duct or system.
•A chimney connector shall not pass through an attic or roof space,
closet or similar concealed space, or a floor, or ceiling. Where passage
through a wall or partition of combustible construction is desired, the
installation shall conform to CAN/CSA-B365, Installation Code for Solid-
Fuel-Burning Appliances and Equipment. (Canadian installations only )
6. Use a chimney connector adapter to connect the chimney connector up to the
chimney. The small ends of the chimney connector should all point down for a
drip free installation. Position all seams toward the back for aesthetics. The
chimney connector must be 6-inch diameter.

395823110a 10
7. Check that all clearances are still within the allowable tolerances.
8. Secure adjoining sections of chimney connector to each other using three
equally spaced sheet metal screws. Secure the connector pipe to flue collar
using three equally spaced sheet metal screws. DO NOT secure chimney
connector to chimney with screws.
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER
APPLIANCE.
9. The unit must be connected to either:
•a code-approved masonry chimney with a flue liner, or
•a 6 inch diameter factory built chimney complying with the requirements
for Type HT chimneys in the standard UL 103.
Minimum Chimney Height
American National Standards Institute ANSI/NFPA 211-92, draft 1-7 states that a
chimney or vent shall be so designed and constructed to develop a flow sufficient
to completely remove all flue and vent gases to the outside atmosphere. The
venting system shall satisfy the draft requirements of the connected appliance in
accordance with the manufactures instructions.
The “3-foot, 2-foot, 10-foot rule” on chimney height states that a chimney must be:
1. at least 3 feet higher than the highest part of the roof opening through which it
passes,
2. and at least 2 feet higher than any part of the roof within 10 feet, measured
horizontally.

Freestanding Installations
If the chimney connector must pass through a combustible wall to reach
the chimney, follow the recommendations in the Wall Pass-Through
section that follows.
The opening through the chimney wall to the flue (the “breach”) must be
lined with either a ceramic or metal cylinder, called a “thimble”, which is
securely cemented in place. Most chimney breeches incorporate
thimbles, but the fit must be snug and the joint between the thimble and
the wall must be cemented firmly (Fig. A)
A special piece called the “thimble sleeve”, slightly smaller in diameter
than standard connectors and most thimbles, will facilitate the removal of
the chimney connector system for inspection and cleaning. Thimble
sleeves are available from your local dealer.
To install a thimble sleeve, slide it into the breech until it is flush with the
inner flue wall. Do not extend it into the actual flue passage, as it could
interfere with the draft.
The thimble sleeve should protrude 1-2” (25-50 mm) into the room. Use
fire cement and thin gasketing to seal the sleeve in place in the thimble.
Secure the chimney connector to the outer end of the sleeve with sheet
metal screws.
Above a Fireplace
In this installation, the chimney connector rises from the stove, turns 90°,
and then goes into the fireplace chimney (Fig. B) The liner of the fireplace
chimney should extend at least to the point at which the chimney
connector enters the chimney. Follow all the guidelines for installing a
chimney connector into a freestanding masonry chimney, and pay special
attention to these additional points:
•Double check the connector clearance from the ceiling: 18” minimum.
•The fireplace damper must be closed and sealed to prevent room air
from being drawn up the flue, thereby reducing the draft. However, it
must be possible to re-open the damper to inspect the chimney.
Wall Pass-Throughs
Whenever possible, design your installation so that the wall connector
does not pass through a combustible wall. If you are considering a wall
pass-through in your installation, check with your building inspector before
you begin. Also check with the chimney connector manufacturer for any
specific requirements.
Accessories are available for use as wall pass-throughs. If using one of
these, make sure it has been tested and listed for use as a wall pass-
through.
The National Fire Protection Association (NFPA) has established
guidelines for passing chimney connectors through combustible walls.

395823110a 13
Many building code inspectors follow these guidelines when approving
installations.
The methods approved by the NFPA are:
•Cutting away all combustible material in the wall a sufficient distance
from the single wall connector, to provide the required 12” (300 mm)
clearance for the connector. Any material used to close the opening
must be noncombustible (as in Fig . C).
•Using a section of double-wall chimney with a 9” (230 mm) clearance
to combustibles.
•Placing a chimney connector pipe inside a ventilated thimble, this is
then separated from combustibles by 6” (150 mm) of fiberglass
insulating material.
•Placing a chimney connector pipe inside a section of 9” (230 mm)
diameter, solid-insulated factory built chimney, with two inches of air
space between the chimney section and the combustibles.

GUIDELINES FOR SAFE OPERATION
Due to high temperatures, the appliance should be located out of traffic and
away from furniture and draperies.
Advise all adults and especially children to be alert to the hazard of high
temperatures and that they should stay away to avoid burns.
Supervise young children when they are in the same room as the appliance
and/or use a fire guard.
It is imperative that the control compartments and circulating air passageways
of the appliance be kept clean.
The appliance should be inspected before use and the chimney cleaned at
least annually. More frequent cleaning may be required due to poor
operation, installation, or low quality fuel.
CAUTION:
•Hot while in operation. Do not touch. Keep children, clothing and furniture
away. Contact may cause skin burns.
•This room heater is a heat producing appliance and may cause severe
burns if touched. Keep children away.
•All furnishings and other materials should be kept a considerable distance
from the appliance.
•Do not over-fire. If any portion of unit or chimney connector starts to glow,
you are over-firing.
This unit is designed as a radiant room heater and should be used for no other
purpose. Be sure to provide combustion air into the dwelling when using the
appliance. A partially open window or outside air register in the vicinity of the
unit would be acceptable for this purpose.
Unattended Fires
Many structure fires have resulted when a slow burning fire has been left
unattended for an extended period of time. These fires normally occur
because combustible materials close to an appliance become heated to the
ignition point by an over-fired appliance which the operator thought was safely
"throttled down."
Fire intensity is a function of several factors. One of these factors is draft.
Normally, increasing draft increases fire intensity. Conversely, increasing the
fire intensity will increase draft. Draft can also be affected by external factors
such as wind strength and direction, outside temperature, airflow in or out of
the structure, and so forth. If one of these factors changes, the draft of a low-
burning appliance may increase. This increased draft may cause dangerously
high temperatures to develop, possibly causing failure of the unit or flue, or
ignition of nearby combustibles. Closing down the combustion air flow
controls may not guarantee that this will not happen.
Exercise extreme caution if a fire must be left unattended

395823110a 15
NOTES ON FIREWOOD
Logs up to 18 inches in length (for Stanford 80 & Harmony I) or 22 inches in
length (for Stanford 140 & Harmony III) allow for better stacking, filling and
operation of your stove.
Use dry wood which by definition must be wood which has been dried under
cover for more than 18 months, in which case the logs contain less than 20%
moisture.
•DO NOT USE FUELS OTHER THAN SEASONED WOOD.
•NEVER USE GASOLINE, GASOLINE-TYPE LANTERN FUEL,
KEROSENE, CHARCOAL LIGHTER FLUID, OR SIMILAR LIQUIDS TO
START OR “FRESHEN UP” A FIRE IN THIS HEATER. KEEP ALL
SUCH LIQUIDS WELL AWAY FROM THE HEATER WHILE IN USE.
•DO NOT BURN TRASH, GARBAGE OR FLAMMABLE FLUIDS SUCH
AS GASOLINE, NAPHTHA OR ENGINE OIL.
Heating the air in a closed building decreases the relative humidity of the air,
which will dry wood and other combustible materials. This drying lowers the
ignition temperature of these materials, thus increasing the fire hazard. To
reduce the risk of fire, some provision should be made for replenishing
moisture to the air whenever a structure is being heated for extended periods.
What is the best wood for the fire?
Some types of wood are easier to light than others.
The best fire wood is always the driest wood.
Using dry wood will minimize creosote build-up.
What are the drawbacks of damp wood?
Damp wood has far less heating power. This lowers the combustion
temperature of the fire, and therefore the output. It is difficult to light, burns
badly and gives off smoke.
Above all the use of damp wood causes the formation of deposits (tarring and
soot staining) in the chimney flue and on the glass door.
Flue gas temperature
The most important aspect of stove operation is maintaining a high
combustion temperature. If the combustion of the fuel is at the correct
temperature, most of the soot and tars (hydrocarbons) are burned. These
hydrocarbons, when not burned, can be seen as tar and creosote deposits on
the internal surfaces of the stove, glass and chimney surfaces. To assist in
maintaining these temperatures, a surface mounted stove thermometer is
recommended.
High combustion temperatures are the secret to clean glass operation. When
loading wood, add one or two logs at a time, depending on size. Loading the

395823110a 16
appliance full of damp wood on a low fire is certain to cause poor combustion
efficiency, resulting in tar and dirty glass.
It is recommended that you heat your stove to at least 400°F before reducing
the air controls. This procedure should always be carried out after reloading.
Storage time for wood
Wood supplied in ready-cut lengths stored immediately under a ventilated
shelter dries quicker than wood stocked in high piles. Quarters (split wood)
dry quicker than round logs. Wood which is too small to split must be drained,
by removing some of the bark. Round logs left in the open for more than a
year end up rotten. The drying time for the fire wood must be at least 18
months to 2 years. This period can be shortened (12 to 15 months) if the wood
is cut to the right length and immediately stored under a ventilated shelter.

OPERATING INSTRUCTIONS
Air intake controls
Primary Air Control
The Primary Air Control allows you to adjust the rate of burn. Sliding the lever to
the left decreases air intake, thus increasing the burn time. Sliding the lever to
the right increases air intake, resulting in higher flames and a cleaner burn.
Adjustable Primary Air Control
(All Models)
Start-up Air Control
Additional air for start-up can be supplied from the ignition booster air control,
located on the back right corner of the Stanford 140 and Harmony III models.
This can be especially helpful when your chimney is cold. Sliding the lever to the
right increases air for start-up. Five minutes after lighting the fire, close the
ignition booster air supply by sliding fully to the left. Do not operate the stove for
long periods of time with the ignition booster open.

(Stanford 140 and Harmony III only)

395823710a 18
Starting a Fire
1. Fully open the primary air control.
2. Place a small amount of paper in the firebox and cover with a few pieces of
kindling.
3. Light the paper in the stove.
4. Once the kindling is burning quickly, add several pieces of wood. Be
careful not to smother the fire. For best results, use smaller pieces of wood
to get the stove temperature high before loading larger wood for sustained
burns.
5. Load logs evenly across the base being cautious not to place wood in front
of the rear edge of the log guard.
6. Close the loading door.
7. With the primary air control open to its maximum, open the stove door a
fraction and burn for 5 minutes. Then close the stove door. Never leave the
stove unattended when the door is open.
8. Adjust the primary air control depending on the temperature of the stove
required.
Reloading the Stove
To prevent smoke blowing into the room follow these recommendations:
1. Open the primary air control to allow fire to recover for a few minutes.
2. Close the primary air control and open the loading door.
3. Rake the embers towards the front of the stove and spread evenly. If there
are logs only partially burned rake these to the front of stove.
4. Feed the logs to the embers. Try to use side loading door as it will allow for
cleaner operation. Load logs evenly across the base being cautious not to
place wood in front of the rear edge of the log guard.
5. Close the loading door.
6. Open the primary air control to its maximum, open the stove door a fraction
and burn for 5 minutes. Then close the stove door. Never leave the stove
unattended when the door is open.
7. Adjust the primary air control depending on the temperature of the stove
required.
-In order to maintain an attractively burning fire, logs should be up to 18"
long (Stanford 80 and Harmony I) or 22” long (Stanford 140 and Harmony
III) and well seasoned.
- High combustion temperatures are the secret to clean glass operation.
When loading wood add one or two logs at a time, depending on size.

395823110a 19
Loading the appliance full of damp wood on a low setting, is certain to
cause poor combustion efficiency resulting in tar and dirty glass.
Always allow the stove to recover before closing for long burning.
Overnight burning
If you fill your appliance with wood and close all air supplies, it is possible
to achieve overnight burning, though it is probable that the glass door will
become dirty.
To keep the glass clean, we recommend you do not shut the primary air
control completely but to leave it slightly open, depending on how the
chimney draws, to achieve slow burning for a maximum of eight to ten
hours (with dry, good quality wood such as oak…). With a good drawing
chimney the air control will need to be closed further than with poor
drawing chimneys.
Disposal of Ashes
Empty the ash pan regularly to prevent the ash from spilling over. Do not
allow ash to build up and touch the under side of the grate. A layer of ash
left over the grate when burning wood will protect the grate, retain heat,
and promote clean combustion.
CAUTION: ASH PAN MAY BE HOT. USE HIGH TEMPERATURE
GLOVES.
To remove the ash from the stove, operate the oscillating grate using the
handle provided. Open the ash pan door, attach handle to ash pan and
remove. Place cover over ash pan. The tool provided for removal of
the ash pan should not be used to carry the ash pan. Use gloves and
hold ash pan on both sides.
Place ashes in a metal container with a tight fitting lid. The closed
container of ashes should be placed on a non-combustible floor or on the
ground, well away from all combustible materials, pending final disposal.
If the ashes are disposed of by burial in soil or otherwise locally dispersed,
they should be retained in the closed container until all cinders have
thoroughly cooled.

395823110a 20
MAINTENANCE
WARNING: DO NOT CLEAN STOVE WHILE HOT.
1. Always keep the area around the unit clean and clear of furniture and
other objects. Keep all furniture and drapery a minimum 36 inches (914
mm) from the heater.
2. Clean the heater surface with a dry or slightly damp cloth. In case of
condensation, clean the affected areas before they dry.
Clean the door glass with glass cleaner or all-purpose cleaning solution.
The glass used is a ceramic type, which can only be broken by impact or
misuse. Do not clean with materials that may scratch or otherwise
damage the glass. Scratches on the glass can develop into cracks or
break. Inspect the glass regularly. If you detect a crack, extinguish the
fire and see replacement of glass on page 16.
3. Inspect the entire unit frequently for proper operation, fit and soundness
of parts. If any malfunctioning, cracked, broken, or loose parts or other
problems are noted, contact your dealer or qualified serviceman to inspect
and repair the unit. DO NOT OPERATE THE UNIT IF INSTALLED OR
FUNCTIONING IMPROPERLY.
4. Check the fit and seal of the doors and ashpan door frequently. For
proper operation an airtight seal must be maintained around these
openings. If the seal is not tight, inspect the gasket. If the gasket needs
replacement, contact your dealer. If the gasket is in good condition, check
the closure latch screws; if these are loose, tighten with a screwdriver and
retest the seal.
5. Store wood in a cool, dry place, well away from any source of flame or
heat. If stored outside, keep the wood covered to protect from rain or
snow. Keep paper, wood, rags and other easily ignited materials away
from the wood. If wood should become wet, separate it and allow it to dry
naturally; do not mix wet and dry wood or pile wet wood on top of dry
wood.
6. Any maintenance other than the items specifically covered in these
instructions must be performed by a qualified manufacturer's
representative.
