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.

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.
