Planning Information
Determine how the chimney will be run, length of run
and chimney components required to complete the job.
(Fig. 4) Never install a chimney below minimum
heights.
In planning a chimney system, it is important to know:
1. The height of a chimney is measured from the
hearth to the exit point on the termination.
2. A chimney cannot be offset more than 30°from a
vertical plane.
3. A chimney may run straight up or it may be neces-
sary to offset it to avoid obstructions.
4. The maximum length of an angled run (total chimney
system) is 20 feet.
5. No more than 2 offsets (4 total 30°elbows in U.S./or
2 total 45°elbows in Canada) per fireplace may be
used.
6. A guy wire stabilizer is required for chimneys extend-
ing more than 6’ (1.8m) above a roof line.
The Ten Foot Rule
Major U.S. building codes specify a minimum chimney
height above the roof top. The “Ten Foot Rule” is a fire
safety rule and not a draft rule. To ensure proper draft,
it is recommended that you always meet or exceed the
“Ten Foot Rule,” especially when installing a termination
on a high pitch roof. (Fig. 5)
The key points of the "Ten Foot Rule" are:
1. If the horizontal distance from the chimney to the
peak of the roof is 10’ (3m) or less, the top of the
chimney must be at least 2’ (610mm) above the peak
of the roof, but never less than 3’ (914mm) in height
above the highest point where it passes through the
roof.
2. If a horizontal distance from the chimney to the peak
of the roof is more than 10’ (3m), a chimney height
reference point is established that is on the surface
of the roof a distance of 10’ (3m) from the chimney in
a horizontal plane. The top of the chimney must be at
least 2’ (610mm) above the reference point, but
never less than 3’ (914mm) in height above the
highest point where it passes through the roof.

Planning an installation is very important to ensure
safety and to save time and money. An installer must
predetermine where a fireplace will be set and how the
chimney system will be run.
Mounting the Fireplace
The fireplace is shipped with lifting handles attached to
each side with lifting straps. NOTE: The lifting straps
are intended for ligting unit off of the skid and final
positioning. Unit should remain on skid until final
positioning. After fireplace is in position, the lifting
handle and straps may be removed or left in place.
A fireplace may only be mounted on the following
surfaces:
1. A flat combustible surface.
2. A raised wooden platform.
3. A concrete block or other solid object placed beneath
each of the four (4) corners of the fireplace.
The fireplace must be spaced 1” from a combustible
back wall and 1” from a combustible side wall or
support. (Page 13, Fig. 17)

Chimney Supports
The chimney system is supported by the fireplace for
vertical chimney heights less than 30’ (9m) above the
hearth. Chimney supports are required if the vertical
height exceeds 30’ (9m). Locate chimney supports at
ceiling holes or other structural framing at 30’ (9m)
heights. Spacing between chimney supports must not
exceed 30’ (9m). Use Chimney Support Model TCS8A.
(NOTE: The TCS8A cannot be mounted directly to
the fireplace.) Support provided by elbow straps fulfills
the support requirement only if they are spaced as
previously described. (A chimney support is 2¹⁄₂"
(64mm) long when installed.)
Angled chimney runs require a support every 6’ (1.8m)
in addition to the elbow straps. Chimney supports are
used for this function. (Fig. 6)

Chase Installation
A chase is a vertical box-like structure which encloses
the fireplace and/or chimney. Chases are typically built
on the outside of the house with fireplace opening cut
into the outer wall of a room. (Page 5, Fig. 2)
If you need help in determining fireplace location or how
the chimney system should be run, contact your Ver-
mont Castings, Majestic Products dealer for assistance.
Insulating Fireplace Enclosure
for Cold Climates
If you live in a cold climate, it is not required but
highly recommended that you insulate fireplace
enclosure to eliminate cold air penetration as much as
possible.
Insulate base of fireplace with a noncombustible
insulation rated for a minimum of 300°F. Insulating is
very important for outside wall installations over a
concrete slab. If fireplace is installed on a platform,
insulation should be placed on top of the platform
before fireplace is set. (Fig. 7)
When a fireplace is installed in a chase or on an
outside wall, enclosure should be treated like any
outside wall in a home. Insulation should be installed
on the inside wall as well as the outside wall(s). In a
chase, it is also a good idea to install a firestop at the
first ceiling level above the fireplace and enclose the
chase with sheeting material. Insulation may then be
installed above sheeting material to assure the space
around the fireplace is totally protected. (Fig. 2)
When installing the chimney, DO NOT caulk between
outer pipe and firestop. It is vital that some air be
allowed to flow through this very thin gap.
CAUTION: When installing a fireplace in an
insulated enclosure, be sure all required air
spaces are maintained. (Page 13, Fig. 17)

Framing
Framing can be constructed before or after the fireplace
is set in place, however, most installers build the frame
before setting the fireplace.
Frame fireplace with 2 x 4 lumber or heavier materials.
Refer to framing dimensions in Figure 1 for basic
fireplace specifications.
NOTE: Framing should be positioned to accommodate
wall covering and fireplace facing material.
EB1 (Receptacle) Hookup
Option for Circulating Models Only
Wiring should be installed by a certified electrician.
Turn off circuit breaker before wiring models.
Once fireplace is secured, complete wiring the fan kit.
Remove knockout in the center of the back of the EB1
and install listed cable clamps. Feed electrical wire
through listed cable clamp leaving approximately six (6)
inches of wire exposed through the EB1. Secure listed
cable clamp to the wire.
Attach white wire from power source to one (1) wire of
receptacle and secure with nut. Attach black wire from
power source to the other wire of receptacle and
secure with nut. Be sure nuts are secured tightly.
Secure EB1 assembly to inside of electrical box
coverplate using two screws. Attach cover to face of the
EB1 while being careful to position excess wire com-
pletely within the EB1, then attach coverplate to fire-
place.
Chimney Set-Up
Since you have already planned the chimney run, you
should know exactly how the installation is to be
accomplished - how much pipe is required, the number
of elbows, if any, and type of termination to be used.
CAUTION: Report to your dealer any parts damaged in
shipment, specifically check the end connection of
chimney sections and elbows.
NOTE: The EWF36A fireplace must use Vermont
Castings, Majestic Products model triple wall 8” chim-
ney components only. The installation procedure
described in this manual applies only to this system.
Straight-Up Chimney Installation
To mark the centerline of the flue, put the fireplace in
final position and measure out from the wall: 9¹⁄₂"
(241mm). Mark a spot on the ceiling directly above the
fireplace. Draw a line parallel to the back wall through
this mark. (Fig. 8)
Using a plumb bob positioned directly over center point
of fireplace flue collar, mark the ceiling to establish the
chimney center point. (Fig. 8)
Offset Installation
In order to clear an obstruction, it may be necessary to
offset chimney from vertical. This is accomplished by
using elbows. Use the 30˚ Offset Elbow table on Page 6
to determine proper offset and parts required.
Each offset requires two (2) elbows. The second elbow
is equipped with support straps. It is very important to
install the second elbow in each offset as close to the
ceiling or support as possible so that the elbow straps
can be secured to framing members to help support the
weight of the chimney.
Determine offset distance of your chimney arrangement
from centerline of fireplace to centerline of chimney
where it is to pass through ceiling.

Measure your offset dimension from straight up chim-
ney center point on ceiling.
Ceiling Chimney Hole/
Possible Obstructions
The size of the hole in ceiling will vary with the angle at
which the chimney passes through ceiling.
Drive a nail up through ceiling at marked chimney
center point. Go to floor above and see where hole will
be cut. Check to see where existing ceiling joists and
other possible obstructions are located...i.e. wiring,
plumbing etc... If necessary, re-position chimney and/or
fireplace to avoid obstructions.
Cutting the Hole
Cover fireplace collar opening and cut proper sized
chimney hole in chimney.
Framing the Ceiling Hole
Frame the ceiling chimney hole as shown in Figure 10.
It is good practice to use framing lumber that is the
same size as the ceiling joists; this is a requirement at
attic level.

provide required the 2” (51mm) air space between the
outside diameter of the chimney and the edges of the
framed ceiling hole.
Positioning, Safety Strips,
Securing the Fireplace
Slide fireplace into position.
Safety strips are used to ensure that any combustible
materials in front of the fireplace are protected even
though a noncombustible hearth extension is required.
When the finished extended hearth is added, the top of
the finished hearth must be flush with the bottom of the
fireplace. “Z” shaped metal safety strips have been
supplied with the fireplace and are required for installa-
tion. The safety strips provided have a 1” offset. For
applications with a greater offset, “Z” shaped strips will
have to be fabricated of metal. Overlap safety strips at
least 1/2” to provide a positive joint. The safety strips
must also extend at least 1¹⁄₂” (38mm) beyond the sides
of the fireplace. (Fig. 11)
NOTE: Safety strips are not required over noncombus-
tible floors where all supports at the base of the fire-
place are noncombustible.
Four (4) nailing flanges are supplied with the fireplace
(found on the fireplace hearth). To level the box and
secure it firmly in place, remove the nailing flanges from
the hearth and install at the sides of the fireplace as
shown in Figure 12.

Installating Outside Air Kit
An outside air kit may be installed on the EWF36A. If
desired, or if local codes mandate the use of an air kit,
then two (2) AK-MSTs are required to complete the
installation (from air kit to the outdoors). If the outside
air kits are to be used, the AK-MSTs MUST be installed
BEFORE the fireplace is enclosed.
NOTE: Four (4) inch Class 1 air duct, material or metal
duct (not supplied) may be used with AK-MST. (For
installation in New York State, only aluminum,
noncombustible flexible or type “O” metal ducting
is permissible.)
Installation Precautions
The duct termination should be located so it is exposed
to an out-of-doors opening at least 100 square inches.
If the duct termination must be located in a crawl space
or basement, be sure the termination area has 100
square inches of ventilation opening to outside air.
The duct termination must be located so it does not
compete for air flow with exhaust fans, gas vent hoods
or other air consuming devices or appliances. It must
not be obstructed by rafters, insulation materials or
other obstructions. The less restrictive the air supply,
the better the AK-MST will perform.
It is a good practice to protect your hands and eyes
during installation by wearing work gloves and safety
glasses.
CAUTION: Do not install termination into a garage
or other area that could contain flammable liquids
or fumes, or into an attic space.
Installation Instructions
Determine the location of the fireplace as described in
the fireplace Installation Manual. Then plan location of
the duct termination and the route of the duct run
between the fireplace and the duct termination.
Duct run must be limited to a maximum distance of 40
feet from the fireplace pipe collar to duct termination.
This will provide the least restriction to air flow. No more
than four (4) 90°elbows can be used. Duct run may be
horizontal, vertical, inclined or any combination of
these. Vertical duct runs must be at least three (3) feet
below the fireplace chimney flue exit. (Fig. 13) You are
now ready to install the AK-MST OutsideAir Kit.

located at the center of both sides of the fireplace.
Use care not to rub against the sharp edges of this
opening to avoid cuts. Remove the four (4) screws
exposed when cover plate is removed. Retain for
future use.
2. Slide the two (2) connecting boxes provided with the
unit into the openings on each side of the unit.
3. Attach the connecting boxes to the inside panel with
four (4) screws removed in Step 1.

Installing the Chimney System
Start by attaching the first chimney section to the collar
on top of the fireplace.
Install the pipe as pictured in Figure 15. When you get
a good lock, you will hear the pipe clearly snap to-
gether. Once sections are snap-locked in place, it is
extremely difficult to get them apart. Make sure the
pipe is firmly snapped and locked together as each
pipe section is mounted.
When installing elbows, only outer pipe will snap- lock.
Middle pipes simply slide into position. Be sure to
always attach straps on upper elbow to a structural
framing member. (Fig. 16)
Continue installing the pipe as required until pipe is
installed up through the ceiling. At this point, you must
install a firestop spacer.

Installing the Firestop Spacer
in the Ceiling Hole
A firestop spacer is used to keep pipe spaced properly
and required for safety.
Nail the firestop spacer (at each corner) to the framing
members of the ceiling hole. NOTE: A firestop spacer
is not required at the roof.
Hole sizes listed in Figure 9 for angled firestop spacers
provide minimum required air space to chimney pipe for
ceiling thickness up to 8” (203mm). When combined
thickness of ceiling material, ceiling joists and flooring
material exceeds 8” (203mm), adjustments must be
made in framing to assure that minimum air spaces to
chimney are maintained.
Proper Firestop Spacer Installation
Figure 17 shows different installation procedures for
both an area that is an attic and an area that is not an
attic.
4. Attach the inlet collar with four (4) #10 screws to the
side near the bottom of the fireplace. Slide the duct
over the collar and attach the duct to the collar using
the plastic tie straps or three (3) screws (screws not
provided). Continue attaching the ducting together
using three (3) screws at each joint until you have
installed sufficient duct to arrive at your duct termina-
tion location.
5. At the termination end, install the duct termination.
This should be installed from the outside of the
home. Cut a hole in the desired location approxi-
mately 4¹⁄₂” in diameter, caulk around the hole, and
slide the termination through the opening from
outside the home. The termination/rain cap should
be caulked around its perimeter to assure a tight
seal. The rain cap opening should be positioned
downward. (Fig. 14)
The AK-MST Outside Air Kit is now installed and ready
for use.

If the area above the ceiling is not an attic, position the
firestop spacer with the flange on the ceiling side and
the angled portion extending up into the hole.
If the area above the ceiling is an attic, position the
firestop spacer with the flange on the top of the framed
hole and the angled portion extending down into the
hole.
Firestop spacers are not available for, nor are they
required on vertical walls.
DO NOT put any sealant around the area where the
outer pipe slides through the firestop spacer. If you
seal this area, it may cause a fire hazard.

Canadian Requirements
for Insulation Shield
In Canada, an attic insulation shield is required to
prevent attic insulaiton from contacxting the chimney
section. Framing dimensions fr the chimney hole should
measure 17¹⁄₂” x 17¹⁄₂” (445mm x 445mm). An attic
shield MUST be installed on top of attic joists (above
the floor level). (Fig. 18)
Continue Installing Pipe to Complete Run
Continue attaching pipe sections to complete system to
next level always being careful that the pipe is firmly
snapped locked in place before proceeding to next pipe
section.
Chimney Supports
If chimney supports are required, they are installed the
same as elbows. Nail chimney support straps to
adjacent structural framing, as shown on Figure 16.
Bend straps as necessary and make sure they are
secure so they will support the weight of the chimney. A
chimney support is 2¹⁄₂" (64mm) long when installed.
Consider this dimension when determining how many
straight chimney sections are needed.
NOTE: Chimney supports are generally used in long
runs in a chase installation.
Additional Ceilings
If you encounter additional ceilings, repeat same steps
required for first ceiling installation. See firestop
illustration in Figure 17.
Penetrating the Roof
Run pipe to roofline. Since chimney system must be
vented to the out-of-doors, you must use an approved
Vermont Castings, Majestic Products termination.
If a chase is used, refer to the installation manual
provided with the termination cap.
Locate Chimney Centerpoint on Roof
Use same procedure detailed in locating center point of
the flue system.
Drive a nail up through roof at the center point. This will
determine center point on outside of the roof.
Cut and Frame Roof Hole
Size of roof hole varies with the type of chimney termi-
nation installed. Refer to installation instructions
provided with Vermont Castings, Majestic Products
chimney termination to find correct size of roof hole.

There must be a 2” (51mm) air space between outer-
most portion of chimney sections and any adjacent
combustible surfaces. (Combustible surfaces include
burnable materials such as: ceiling members, joists,
flooring, combustible insulation and roof structures.)
WARNING: Do not pack required air spaces with
insulation or other materials.
Mark an outline of the roof hole around the center of the
point nail. NOTE: Hole dimensions given in the chim-
ney top installation instructions are horizontal dimen-
sions; therefore, the hole size must be marked on the
roof accordingly.
Cover the opening of the installed chimney so debris
cannot get into the system.
Cut and frame the hole. It is good practice to use
framing lumber that is the same size as the rafters.
Install the frame securely because the chimney top and
flashing anchored to the frame must be able to with-
stand heavy winds.
Install Remainder of Chimney Sections
Since you have already preplanned the height of your
termination according to the Ten Foot Rule , continue to
install pipe to the predetermined height.
Check the chimney top installation instructions for
details on how high above the roof top the chimney
sections (all pipes) should extend.
Install Top Housing or Termination
Follow the installation instructions provided with the
Vermont Castings, Majestic Products chimney termina-
tion you have selected.
Installing Chimney in a Chase
Refer to Figure 2, Page 5 for an illustration of a typical
chase installation.
CAUTION: Treatment of firestop spacers and construc-
tion of chase may vary with type of building. These
instructions are not a substitute for local building codes.
You must check your local building codes to determine
specific requirements for your city or state. NOTE:
Other building materials may be required in addition to
Vermont Castings, Majestic Products Firestop Spacers.
Finishing
CAUTION: All joints between the finished wall and the
fireplace surround (steel front) must be sealed with
noncombustible material to prevent cold air leakage into
the room. (Fig. 19)
NOTE: No material may cover black cast face.
Finish Wall
Finish the wall with material of your choice. Do not
install a combustible mantel shelf less than 12”
(305mm) above the firebox grille opening. Do not
install a mantel face plate less than 6” (159mm)
from top of grille opening. (Fig. 21) If a combustible
material is used below a flat mantel shelf, consult your
local building codes for minimum clearance from top of
fireplace opening to bottom of mantel shelf.
All joints (top, bottom and sides) where wall or decora-
tive facing material meets fireplace surround must be
completely sealed with a noncombustible material.
(Figures 20 and 24)
NOTE: No side wall protection is required for fireplaces
installed at 45°to two (2) side walls (corner installation).

Mantels
The height that a combustible mantel is fitted above the
fireplace is dependent on the depth of the mantel. This
also applies to the distance between the mantel leg (if
fitted) and the fireplace.
For the correct mounting heights and widths, refer to
Figures 21 and 22. When using paint or lacquer to
finish the mantel, such paint or lacquer must be heat
resistant to prevent discoloration.
Side Wall Protection
Adjacent combustible side walls that are within mini-
mum dimensions shown in Figure 24 of the fireplace
opening must be protected with Majestic Wall Shield
Model SP40 or a specifically built wall shield described
in Figure 19.
The special wall shield design described in Figure 19 is
an alternate method of adding protection to side walls
and can be used in place of the SP40 with the same
wall clearances specified for the SP40. Rt must =1.85
minimum.
Examples of wall shield insulation:
1. Manville - CERAFORM 126, K=.27,
1/2 inches thick
2. EH2416, K = .458,
1 inch thick required.
Hearth Installation
A hearth extension is required to protect a combustible
floor in front of the fireplace. Refer to Figure 25 for
minimum dimensions and mounting detail.
NOTE: Hearth Extension must not cover the air
inlet opening of a fireplace.
The hearth extension described in Figure 25 must be a
durable noncombustible material with a minimum (total)
Rt value of 1.09; see Figure 23 for examples. The
overall height (above a combustible floor), depth and
width must be as indicated, with the extension centered
to the fireplace opening.

Operation
Attach Handles
The fallaway handles are used to open and close the
front doors. Remove after each use so they will not get
hot. Keep in convenient location for each use. (Fig. 26)
Assemble the primary air control and damper handles
by passing the 3³⁄₈” screw through the ceramic shaft
and into the bright metal hub. Tighten carefully until
snug. Do not overtighten. Ceramic handle could crack.
(Fig. 27)

EWF36A Controls
Three controls regulate the performance of the
EWF36A fireplace: A primary air control supplies
oxygen for the fire, the damper directs air flow within
the fireplace and a variable-speed fan control, or
rheostat, regulates the warm air flow into the room.
(Fig. 28)
Primary Air Control
A single air control regulates the amount of heat the fire
will produce and how long it will burn.
FP1396
Fig. 27 Assemble primary air control and damper handles.
Screw
Ceramic Shaft
Metal Hub
The primary air control is located in the upper left
corner of the unit. (Fig. 26) It is the primary source of
air for starting, maintaining, and reviving the fire.
Generally, more air entering the fireplace makes the fire
burn hotter and faster, while less air prolongs the burn.
The air supply is open to the maximum when the
control lever is rotated clockwise, and closed when
rotated counterclockwise. To vary the burn rate, adjust
the control to the desired position in between these
extremes; opening the primary air control makes the
unit burn hotter. Closing the control slows the unit
down. You may adjust to any position you desire.
The Damper
The damper directs air flow within the fireplace.
The damper is operated by moving the lever located in
the upper right corner of the unit. It has two positions:
Open to start or revive the fire and closed, for normal
operation and to control burn rate. The damper is open
when the lever is fully rotated counterclockwise and
pulled out and closed when pushed in. When the
damper is in the open position, with the lever pulled out,
and rotated fully in the clockwise direction, the handle
can ‘telescope’ back without closing the damper or any
damper movement. There are no intermediate settings
for the damper.
NOTE: Full clockwise or counterclockwise movement of
the damper handle is approximately 50°.
NOTE: Always open the damper before opening the
doors. Close damper to set burn rate.

The Fan
Heated air from the fireplace is forced into the room by
an internal fan. The control for the fan is in the right
corner of the unit.
“Off” is to the far left.
“High” is just to the right of “Off.”
“Low” is to the far right.
Variable adjustment of the fans is possible with any
setting between “high” and “low.”
For best results, coordinate fan speed with the setting
of the primary air control. For example, when the air
control lever is set at “low,” also set the fan at “low.”
With the air control set for maximum heat, set the fan at
“high.”
Glass Doors
The EWF36A is intended for use with the doors fully
closed or fully open only when optional spark screen is
installed. (Fig. 29) NOTE: When operated with the
doors open and spark screen in place, the damper
MUST be in the open position.
Burn Only High-Quality Wood
The EWF36A is designed to burn natural wood only;
do not burn fuels other than that for which it was
designed.
You will enjoy the best results when burning wood that
has been adequately air-dried. Avoid burning “green”
wood that has not been properly seasoned.
The best hardwood fuels include oak, maple, beech,
ash, and hickory that has been split, stacked, and air-
dried outside under cover for at least one year.
For areas that do not have a supply of hardwood,
commonly burned softwoods include tamarack, yellow
pine, white pine, Eastern red cedar, fir, and redwood.
These too should be properly dried. Your EWF36A will
accept wood up to 24" (610 mm). Longer wood pieces
work better than short ones.
Wood should be stored under cover to maintain dry-
ness, and should be dried at least six months for
optimum heating and fire-viewing performance. Even
for short-term storage, however, keep wood a safe
distance from the heater and keep it out of the areas
around the heater used for refueling and ash removal.
Use the Air Control Settings
that Work Best for You
No single air control setting will fit every situation. Each
installation will differ depending on the quality of the
fuel, the amount of heat desired, and how long you wish
the fire to burn.
The control setting also depends on your particular
installation’s “draft,” or the force that moves air from the
stove up through the chimney. Draft is affected by such
things as the length, type, and location of the chimney,
local geography, nearby obstructions, and other factors.
Too much draft may cause excessive temperatures in
the fireplace. On the other hand, too little draft can
cause backpuffing into the room and/or the “plugging” of
the chimney or combustor.
How do you know if your draft is excessively high or
low? Symptoms of too much draft include an uncontrol-
lable burn or a glowing-red part of the EWF36A front. A
sign of inadequate draft is smoke leaking into the room
through the stove or chimney connector joints, low heat,
and dirty glass.
In some newer homes that are well-insulated and
weather-tight, poor draft may result from insufficient air
in the house. In such instances, an open window near
the stove on the windward side of the house will provide
the fresh air needed.
Another option for getting more combustion air to the
stove is to duct air directly from the outside to the stove.
In fact, in some areas provisions for outside combustion
air are required in all new construction.
Your EWF36A is designed so that it is possible to
incorporate outside air for combustion. Directions for
installing the optional AK-MST outside air ducts are
included with the kits and beginning on Page 11 of this
instruction.
When first using the stove, keep track of the settings of
the air controls. You will quickly find that a specific
setting will give you a fixed amount of heat. It may take
a week or two to determine the amount of heat and the
length of burn you should expect from various settings.
Most installations do not require a large amount of
combustion air, especially if adequate draft is available.
Do not for any reason attempt to increase the firing
of your heater by altering the air control adjustment
range outlined in these directions.

Starting and Maintaining a Wood Fire
Burn solid wood fuel only in the EWF36A, and burn
it directly on the grate. Do not elevate the fuel. Do
not burn coal or other fuels.
Minimize thermal stress by allowing the plates to adjust
gradually during an initial break-in fire by following
Steps 1-3 below.
WARNING: Operate your EWF36A only with the
doors fully closed. If the door is left partially open,
gas and flame may be drawn out of the fireplace
opening, creating risks of both fire and smoke.
1. Open the primary air control fully.
2. Open the damper.
3. Lay some crumpled newspapers on the bottom
grate. Place on the paper six or eight pieces of dry,
finely-split kindling. On the kindling lay two or three
larger sticks of split dry wood approximately 1-2"
(25-50 mm).
Do not use chemicals or fluids to start the fire. Do
not burn garbage or flammable fluids such as
gasoline, naptha, or engine oil.
Also, never use 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 it is in use.
4. Light the newspaper and close the door. Gradually
build up the fire by adding a few 3-5" (80-120mm)
diameter splits.
If this is your initial break-in fire, let the fire burn brightly,
but not to excess. Control the fire's intensity by adjust-
ing the air control lever. After an hour or so stop adding
wood so that the fire dies out gradually.
For ongoing operation after the initial break-in, continue
to add a few sticks at a time of a progressively larger
size. Continue until you have a live ember bed at least
2-3" (51-76mm) deep. This may take an hour or longer.
CAUTION: THE EWF36A IS HOT WHILE IN OPERA-
TION! KEEP CHILDREN, CLOTHING, AND FURNI-
TURE AWAY. CONTACT MAY CAUSE SKIN
BURNS.
NOTE: Some chimneys need to be “primed,” or
warmed up, before they will draw sufficiently to open
the damper. To correct this situation, roll up a couple
pieces of newspaper, place them on top of the kindling
and toward the back of the stove, light them, and close
the doors. This should heat the chimney enough to
initiate a draft.
Once the draft is established, open the front door and
light the rest of the fuel from the bottom. Do not light the
main bed of fuel until the chimney begins drawing, and
repeat the procedure as often as necessary if the initial
attempt is unsuccessful.
5. Once a good ember bed of at least 2-3" (51-76 mm)
has formed, let the fire burn hot for an additional ten
to fifteen minutes.
6. Close the damper and the primary air control to a
medium-low setting as described on Page 18. The
fire volume will diminish immediately, but the
fireplace will continue to heat up. Maintain control of
the fire using the primary air control, and remember:
reduce the setting for less heat, increase the setting
for more heat. Refer to the air control settings
information on Page 18 for recommended settings at
different burn rates.
DO NOT OVERFIRE THIS HEATER. Overfiring may
cause a house fire, or can result in permanent damage
to the stove. If an exterior part of the EWF36A glows,
you are overfiring.
Reloading and Reviving a Wood Fire
•Open the damper and set the air control on “High,”
and wait at least fifteen seconds for the draft to
increase. Open the door slowly.
•Check the ash level, and empty the ash pan if
necessary. Replace the pan.
•Add the fuel, smaller pieces first. If it is necessary to
use wood smaller than the 24" (610mm) optimum
size, be sure to fill the firebox as completely as
possible by loading the wood pieces alternately on
the left and right. Split wood will fill the firebox more
completely and reduce the frequency of reloading.
If you have an ember bed of at least 2-3" (51-76 mm),
leave the thermostat set on "high" for 10-15 minutes. If
the ember bed is less than 2-3" (51-76mm), you may
have to let it burn longer.
Finally, close the damper and adjust the air control and
fan speed for your desired heat level.
NOTE: If the charcoal bed is relatively thick and your
fuel is well-seasoned, it is possible to add fresh fuel
(smaller pieces first), close the door and damper, and
reset the air control within five minutes.
Special Tactics for Cold-Climate Heating
The EWF36A is capable of producing in excess of
100,000 Btu's/hour and heating an area of up to 2,500 sq.
ft.(558 sq. m) However, many factors affect heating
performance and can influence the extent to which the
EWF36A can heat a given area.
A well-insulated home, located in a moderate climate
and with the EWF36A Fireplace located centrally in an
open floor plan, will be easier to heat than a drafty
home in the far north in which the EWF36A is installed
on an exterior wall at the end of a long house.
