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 sup-

port. (Page 13, Fig. 17)

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.

Fig. 4 Installed lengths of chimney sections.

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 neces­sary to offset it to avoid obstructions.

4. The maximum length of an angled run (total chimney
system) is 20 feet.

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 SKCS8.

(NOTE: The SKCS8 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 insu
lated 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 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.

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: Fireplaces may use CFM Corporation Model
SK8, or Model S (three wall) chimney systems. The
BR/BC Series Fireplace will accept the SK8 chimney
system as is; but a TWABR adapter collar is required
when using the Model S (triple wall) chimney system.
The installation procedure described in this manual
applies only to the SK8 system. Either chimney system

may be used, but may not be mixed.

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)

FP1563

Fig. 8 Locate centerline of chimney with plumb line.

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.

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 chimney

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 1¹⁄₂” (38 mm) 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

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.

Installing Outside Air Kit

An outside air kit may be installed on the EWF30.
The AK-MST allows for 100% of required combustion
air to come from outside source. If desired, or if local
codes mandate the use of an air kit, then an AK-MST
is required to complete the installation (from air kit to
the outdoors). If the outside air kit is to be used, the
AK-MST 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.)

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

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.

now ready to install the AK-MST Outside Air Kit.

1. Remove and discard the outside air cover plate
located at the center of the right side of the fireplace.
Use care not to rub against the sharp edges of this
opening to avoid cuts.

2. 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

using three (3) screws at each joint until you have
installed sufficient duct to arrive at your duct termina­tion location.

3. 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)

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.

12

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.

20008662

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.

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.

Canadian Requirements

for Insulation Shield

In Canada, an attic insulation shield is required to pre­vent attic insulaiton from contacxting the chimney sec­tion. Framing dimensions for the chimney hole should
measure 14¹⁄₂” x 14¹⁄₂” (368 x 368 mm). 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.

Additional Ceilings

If you encounter additional ceilings, repeat same steps
required for first ceiling installation. See firestop illustra-

tion 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
CFM Corporation 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 ter­mination installed. Refer to installation instructions
provided with CFM Corporation chimney termination to
find correct size of roof hole.

20008662

13

Vermont Castings EWF30

There must be a 1¹⁄₂” (38 mm) 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 dimen­sions; 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 sec-

tions (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”
(305 mm) above the firebox grille opening. Do not
install a mantel face plate less than 6” (159 mm)
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. (Fig­ures 20 and 24)

NOTE: No side wall protection is required for fireplaces
installed at 45° to two (2) side walls (corner installation).

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)

Operation

Attach Handles

The fallaway handle is used to open and close the front
doors. Remove after each use so the handle will not get
hot. Keep in convenient location for each use. (Fig. 26)

Assemble the primary air control and damper handles
by passing the screw through the wood shaft and into
the bright metal hub. Tighten carefully until snug. Do not

overtighten. Wood handle could crack. (Fig. 27)

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 pushed down, and closed when pulled up. 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.

EWF30 Controls

Three controls regulate the performance of the EWF30
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.

18

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 pulled out and closed when pushed in.
There are no intermediate settings for the damper.

NOTE: Always open the damper before opening the
doors. Close damper to set burn rate.

20008662

Vermont Castings EWF30

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. (counterclockwise )
“High” is just to the right of “Off.”
“Low” is to the far right. (clockwise )

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 EWF30 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 EWF30 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 EWF30 will accept
wood up to 23” (584 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 fireplace 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 EWF30 front. A
sign of inadequate draft is smoke leaking into the room
through the fireplace 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 fireplace on the windward side of the house will
provide the fresh air needed.

Another option for getting more combustion air to the
fireplace is to duct air directly from the outside to the
fireplace. In fact, in some areas provisions for outside
combustion air are required in all new construction.

Your EWF30 is designed so that it is possible to incor
porate outside air for combustion. Directions for install­ing the optional AK-MST outside air duct is included
with the kit and beginning on Page 11 of this instruction.

When first using the fireplace, 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 EWF30

Starting and Maintaining a Wood Fire

Burn solid wood fuel only in the EWF30, 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 EWF30 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 EWF30 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 fireplace, 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 fire
place 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 fireplace. If an exterior part of the EWF30 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 nec-

essary. Replace the pan.

• Add the fuel, smaller pieces first. If it is necessary

to use wood smaller than the 23” (584 mm) 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 air control set on “high” for 10-15 minutes. If
the ember bed is less than 2-3” (51-76 mm), you may
have to let it burn longer. Also, depending on the quality
of your wood, the temperature of the firebox and the
draft conditions of your chimney, it may be helpful to
leave the door cracked open for up to 5 minutes. This
will help to ignite freshly loaded wood. NEVER leave
the fireplace unattended unless the door is completely
closed. Overfiring could result from leaving the door
cracked open.

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 EWF30 is capable of producing in excess of
55,000 Btu’s/hour and heating an area of up to 2,400
sq. ft. (223 sq. m) However, many factors affect heating
performance and can influence the extent to which the
EWF30 can heat a given area.

20

20008662

Vermont Castings EWF30

A well-insulated home, located in a moderate climate
and with the EWF30 Fireplace located centrally in an
open floor plan, will be easier to heat than a drafty
home in the far north in which the EWF30 is installed on
an exterior wall at the end of a long house.

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 EWF30 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 fireplace, and
empty if necessary using the following procedure:

• Open the damper.

• Open the load door.

• Remove the ash pans from under the hearth

brick. CAUTION: Ash may contain hot coals and
must be treated with extreme care. Hold the 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 EWF30: 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 EWF30 Fireplace Looking New
and Working Its Best

Care of the Cast Iron Surface

An occasional dusting with a dry rag will keep your
EWF30 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 fireplace paint
available from your local dealer. Apply the paint spar­ingly. Two light coats are better than one heavy one.

Cleaning the Glass

The EWF30 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 EWF30 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 resis-

Handle Stub

Fig. 30 Turn the striker screw to tighten or loosen the door
latch.

tance, 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

How to Replace Gaskets

The EWF30 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.

Replaceable Fiberglass Gaskets

Gasket Size... ...And The Parts It Seals

1/2” The door to the front
3/16” The glass seal to the door
1/2” Braided Damper to top plate

Should you need to change a replaceable gasket, wait
until the fire is out and the fireplace 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 easily­accomplished steps are involved:

22

20008662

Vermont Castings EWF30

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 fireplace 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 EWF30 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 EWF30 has been designed to reduce creosote
build-up significantly. However, regular chimney in­spection and maintenance must still be performed. For
safety, good fireplace 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
damper 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.

20008662

23

Vermont Castings EWF30

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.
