with illustration above):
A. Height of the chimney is measured
from the hearth to the chimney exit.
EWF36A
Maximum:50'
Minimum:
Without Elbows17’0"
With 2 Elbows*19’0"
With 4 Elbows*21’0"
B. Do not use more than 4 elbows per
chimney.
Attach the straps of the return (top)
elbow to a structural framing member.
The offset (first) elbow of any pair does
not have straps.
C. The chimney cannot be more than 30˚
(45˚ in Canada) from the vertical plane in
any installation*.
D. The maximum length of the angled run
of the total chimney system is 20 feet. (G
plus H cannot exceed 20 feet.)
E. A chimney support (Model TCS8A) is
required every 6 feet of angled run of
chimney. Chimney supports are required
for every 30 feet and 60 feet of vertical
chimney height above the hearth.
Determine the offset distance of your
chimney arrangement from the centerline
of the fireplace to the centerline of the
chimney where it is to pass through the
first ceiling.
NOTE: This offset distance may not be
your full offset distance. See Examples 2
and 3.
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)

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 extending 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.

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)

Installation
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)
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 Vermont Castings, Majestic Products dealer for assistance.

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 completely within the EB1, then attach coverplate to fireplace.
Using a plumb bob positioned directly over center point
of fireplace flue collar, mark the ceiling to establish the
chimney center point. (Fig. 8)

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” chimney 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)
20005167
FPC556a
Fig. 8 Locate centerline of chimney with plumb line.
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
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.

Locate center point of the chimney on ceiling as though
a straight up chimney arrangement is to be used.
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.
The following table gives firestop spacer model numbers:
The inside dimension of the frame must be the same
as the hole size selected from Figure 9 in order to
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 installation. 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 noncombustible floors where all supports at the base of the fireplace 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.)
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 Outside Air Kit.

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.

1. Remove and discard the outside air cover plate
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.

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 termination 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 approximately 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.

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 together. 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

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.
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)
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.
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.
20005167
Cut and Frame Roof Hole
Size of roof hole varies with the type of chimney termination installed. Refer to installation instructions
provided with Vermont Castings, Majestic Products
chimney termination to find correct size of roof hole.

Page 14
Vermont Castings EWF36A
There must be a 2” (51mm) air space between outermost 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 chimney 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 withstand 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
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 decorative facing material meets fireplace surround must be
completely sealed with a noncombustible material.

Side Wall Protection
Adjacent combustible side walls that are within minimum 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

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.

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.
Primary Air Control
Fig. 28 EWF36A controls.
Damper
FP1203
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.
18
20005167
Page 19
Vermont Castings EWF36A
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 airdried 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 dryness, 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 uncontrollable 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.

Vermont Castings EWF36A
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 adjusting 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 OPERATION! KEEP CHILDREN, CLOTHING, AND FURNITURE 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.
20
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.
20005167
Page 21
Vermont Castings EWF36A
Different results may be experienced even in the same
installation if you switch from burning good, dry wood to
wood that is partially rotted or inadequately seasoned.
To compensate for these factors in cold climates, it may
be necessary to operate the EWF36A with the air
control set to a higher level more of the time.
Remove and Store Ash Safely
Check the ash pan before reloading the stove, and
empty if necessary using the following procedure:
•Open the damper.
•Open the load door.
•Remove the ash pans from under the hearth
brick. The EWF comes with a cover for the ash
pan. To install this cover, hold just above the ash
pans with the handle on the cover closest to you.
Slide the cover onto the top of the pan as you pull
the pan out. As the pan slides out, the flange on
the back of the cover should slide into the slot in
the back of the ash pan and the flange on the
front of the cover will slide over the handle on the
ash pan. CAUTION: Do not pull the pan out too
far before the cover engages the slot. Ash may
contain hot coals and must be treated with
extreme care. Hold the covered ash pan with both
hands to avoid dropping or spilling the ashes.
•Take the pans outdoors and empty the ash into
an ash container.
•Before replacing the ash pan, clear away any ash
that has spilled over the sides and back of the
pan.
•Replace the ash pans and front door.
Empty the ash pans regularly, typically every one to
three days. The frequency will vary depending on how
you operate your EWF36A: If you burn more wood at
higher heat output settings, and ash will accumulate
faster.
Ash should be removed frequently and placed outdoors
in a metal container with a tight-fitting lid. The closed
container of ash should be placed on a noncombustible
floor or on the ground, well away from all combustible
materials, pending final disposal. If the ash is disposed
of by burial in soil or otherwise locally dispersed, it
should be retained in the closed container until all
cinders have thoroughly cooled. Wood ash may be
used as a garden fertilizer.
CAUTION: Never use your household or shop vacuum
cleaner to remove ash from the fireplace; always
remove and dispose of the ash properly.

Maintenance
Keep your EWF36A Fireplace Looking New
and Working Its Best
Care of the Cast Iron Surface
An occasional dusting with a dry rag will keep the painted
cast iron of your EWF36A fireplace looking new.
If the paint needs retouching, first allow the surface to
cool completely. Wire-brush areas needing to be
painted. Touch-up with high temperature stove paint
available from your local dealer. Apply the paint sparingly. Two light coats are better than one heavy one.

Cleaning the Glass
The EWF36A glass system requires a minimum amount
of cleaning. Most carbon deposits that accumulate will
burn off during hot fires.
Ash residue that accumulates on the glass should be
removed periodically to prevent etching. To clean the
glass, follow this procedure:
• Be sure the glass is completely cool.
• Cleaning with water will work in most cases. Use
a glass cleaner especially made for this purpose
only if deposits are especially heavy. (If heavy
deposits are a frequent occurrence, however,
evaluate your operating techniques.)
• Rinse the glass thoroughly.
• Dry the glass completely.
NOTE: The EWF36A glass is coated with a special
material on the outside that helps reflect heat back
into the fire chamber. Do not attempt to remove
this coating.
Adjust the Door Latch Periodically
The front door of the fireplace should close securely to
prevent accidental opening and should close tightly to
prevent air from leaking into the fire chamber. The door
handles will be positioned vertically when the door is
closed.
Over a period of time, the gasket around the door will
compress and the latch may need adjustment. To
adjust the handle, follow this procedure (Fig. 30):
1. Loosen the small lock nut with a wrench.
2. Extend the striker screw one turn by turning it with
an Allen wrench.
3. Retighten the lock nut, while at the same time
holding the striker screw with the Allen wrench to
prevent its turning.
Test the door seal. Close the door on a dollar bill and
attempt to pull it free. If the bill is freed with little

resistance, the gasket isn’t snug enough at that spot.
Continue to make small adjustments until the setting is
right.
If additional adjusting of the latch does not enable the
door to seal sufficiently in one area, try “adjusting” the
gasket in that area. Pack more cement or a smaller
diameter gasket into the channel beneath the gasket so
that the main gasket is raised and makes contact with
the door frame. This procedure should solve the
problem. If the gasket needs replacing, follow the
directions beginning on Page 23.
ST531
The Catalytic Element
This wood heater contains a catalytic combustor, which
needs periodic inspection and replacement for proper
operation. In the United States, it is against the law to
operate this wood heater in a manner inconsistent with
the operating instructions in this manual, or if the
catalytic element is deactivated or removed.
Under normal operating conditions, the catalytic combustor should remain active for two to six years (depending on the amount of wood burned). However, it is
important to monitor the combustor periodically to
ensure that it is functioning properly, as well as to
determine when it needs to be replaced. A nonfunctional combustor will result in a loss of heating efficiency, and an increase in creosote and emissions.
Inspection and Cleaning
Inspect the combustor “in place” for fly ash accumulation and physical damage three times per year. Do not
remove the combustor unless a more detailed inspection is warranted because of diminished performances
as outlined in the next section.
22
20005167
Page 23
Vermont Castings EWF36A
When to Suspect a Combustor Problem
The best way to evaluate the performance of your
EWF36A ’s combustor is to observe the amount of smoke
leaving the chimney - both when the combustor has
“lighted-off” and when it has not. Follow these steps:
• With a fire going and the combustor properly acti-
vated, with the damper closed to route smoke
through it as described in the Operation Section, go
outside and observe the smoke leaving the chimney.
• Then, open the stove damper and once again check
the smoke leaving the chimney.
You should see significantly more smoke when the
stove damper is open and exhaust does not pass
through the combustor. However, be careful not to
confuse smoke with steam from wet wood. Steam
dissipates in the air quickly; smoke does not.
If this test indicates a problem, consider other possible
factors as well, such as the weather or a change in the
quality of your fuel. In warm weather, draft is weaker
than it is in colder winter weather and fires can burn
sluggishly. Small, hot fires are a good solution under
these conditions.
Burning “green” (insufficiently seasoned) wood will
result in poorer performance than burning properly
seasoned fuel. You may have to run your fireplace
hotter (more air) to achieve acceptable performance
using green or wet wood.
Also consider any changes in your operating routine.
Once you have ruled out any other possible causes for
a decline in performance, inspect and clean the combustor if necessary.
Inspecting the Combustor
Use a flashlight and mirror, if necessary, to examine the
combustor. If no fly ash or damage is visible, the
inspection is complete. If closer examination, cleaning
or replacing is needed, go to the next section.
Removing, Cleaning or
Replacing the Combustor
1. Allow fireplace to cool.
2. Tap the left and right wedges back and remove. (Fig.
31)
3. Carefully slide catalyst assembly to the back of the
fireplace and out of the retaining brackets.
4. Check the combustor’s honeycomb-like element for
a buildup of fly ash. If any is evident, take the
combustor outside and clean it by blowing air gently
through it. Do not push anything through the honeycomb; do not use compressed air to clear the

passages. Such abrasion can scrape the thin
coating of platinum (the catalyst) off the ceramic
base, shortening the catalyst’s life and reducing its
effectiveness.
5. Inspect the element for damage or degradation.
Although small hairline cracks will not affect performance, the element should be essentially intact. If
the element is broken in pieces or has sections
missing, it should be replaced. Call your local
Vermont Castings, Majestic Products authorized
dealer for a replacement element.
6. If the element is in good condition and clean,
reinstall it in the fireplace.
Operate the stove in your usual manner for two weeks,
inspecting the chimney and the chimney connector
frequently during this period.
If creosote does not build up as fast, it is likely that the
performance change was caused by fly ash deposits on
the catalytic element. However, continue the inspections of the chimney system for a few weeks to ensure
that proper performance continues.
If you continue to find a significant creosote buildup or if
you continue to see excessive smoke form the chimney,
the catalytic element will need to be replaced. Contact
your nearest Vermont Castings, Majestic Products
authorized dealer.
NOTE: Use only the replacement catalyst supplied by a
Vermont Castings, Majestic Products dealer.

How to Replace Gaskets
The EWF36A uses rope-type fiberglass gaskets to
make a tight seal between some parts. With use,
particularly on those parts that move, gaskets can
become brittle and compressed and can begin to lose
their effectiveness. These will need periodic replacement.
All of the gaskets used are made of fiberglass. The
four sizes of replaceable gasket are listed below, along
with their application.

Vermont Castings EWF36A
Replaceable Fiberglass Gaskets
Gasket Size......And The Parts It Seals
1/2"The door to the front
5/8”Door to the hearth brick support
3/16"The glass seal tothe door
1/2”Cat holder to top plate
1/2” BraidedDamper to top plate
Should you need to change a replaceable gasket, wait
until the fire is out and the stove has cooled. Be sure to
follow the standard safety procedure for working with
dusty materials: Wear safety goggles and a dust mask.
The procedure for replacing gaskets is the same,
regardless of the gasket location. Four easily-accomplished steps are involved:
1. Remove the existing fiberglass gasket by grasping
an end and pulling firmly.
2. Use a wire brush or the tip of a screwdriver to clean
the channel of any remaining cement or bits of
gasket.
3. Apply a thin bead of stove cement to the newlycleaned groove.
4. Pack a new gasket into the groove. Wait until you
have placed all but a couple inches from the end
before you trim the end to an exact fit.
5. Place door back on fireplace, latch door and keep
closed for 1/2 hour to insure cement has set.
Replacing the Door Gaskets
Remove the door by lifting it straight up off its hinge
pins. Lay it face down on a padded surface.
Follow steps 1-4 as described above.
Replace Damaged Door Glass Immediately
Do not operate the fireplace with damaged glass door.
Use the following procedure for glass replacement.
NOTE: Replace glass only with the replacement glass
made for this unit, available from your authorized
dealer.
• Remove the door and loosen the retaining clips which
hold the glass to the door frame. Remove clips. Use
caution when handling broken glass.
• Examine the gasket that seals the glass to the door
frame. Replace if necessary with gasket obtained from
your local Vermont Castings’ Authorized Dealer. See
the directions for gasket replacement on Page 23.
• Check the flat surface of the door frame, and clear
away debris if necessary.
• Install the new glass.
• Secure the clips, being careful not to overtighten. Be
sure the glass is firmly seated against the gasket.
• Replace door.
The Chimney System
A Clean Chimney System is
Safer and Works Better
Although the combustion system in the EWF36A can
reduce creosote formation dramatically, it is not a
substitute for regular inspection and cleaning of the
chimney and chimney connector.
Learn to Recognize —
and Avoid — Creosote
The EWF36A has been designed to reduce creosote
build-up significantly. However, regular chimney
inspection and maintenance must still be performed.
For safety, good stove performance, and to protect your
chimney and chimney connector, inspect your chimney
and chimney connector on a regular schedule. Clean
the system if necessary. Failure to keep the chimney
and connector system clean can result in a serious
chimney fire.
When wood is burned slowly, it produces tar, organic
vapors and moisture which combine to form creosote.
The creosote vapors condense in the relatively cool
chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When
ignited, this creosote makes an extremely hot fire within
the flue system that can damage the chimney and
overheat adjacent combustible material. If a significant
layer of creosote has accumulated —1/8" (3mm) or
more — it should be removed to reduce the risk of a
chimney fire.
If you do experience a chimney fire, act promptly to:
•Close the primary air control lever and the
damper
•Get everyone out of the house.
•Call the Fire Department.
You should inspect the system every two weeks during
the heating season as part of a regular maintenance
schedule. To inspect the chimney, let the fireplace cool
completely. Remove the termination top. Then, using a
strong light, sight down into the chimney flue.
Clean the chimney using a specially designed brush the
same size and shape as the flue liner. Flexible fiberglass rods are used to run the brush up and down the
liner, causing any deposits to fall to the bottom of the
chimney where they can be removed through the cleanout door on top of the fireplace.
If you can not do the chimney inspection yourself,
contact your local Vermont Castings' Authorized Dealer,
or engage a professional chimney sweep to perform the
inspection and cleaning of the chimney.
24
20005167
Page 25
The prefabricated chimney used with your fireplace
should be cleaned from above using an 8" round brush
and the appropriate number of extension rods for
complete access.
The chimney cap first must be removed following the
procedure recommended by the manufacturer. After
thoroughly cleaning the chimney, reinstall the chimney
cap according to the manufacturer’s directions.
Maintenance Schedule
Fireplace:
Daily:
• Ash should be removed before the level reaches the
top of the pan. Check each time you re-load, or at
least once a day.
• Keep the area around the fireplace clear of any
combustible material.
Yearly Spring Cleaning:
• Remove ash from the fire box and replace with a
moisture-absorbing material (such as Kitty Litter) to
keep the interior of the fireplace dry.
•Touch up painted surfaces with black paint.
