CAUTION:
Do not expose the fireplace to the elements (i.e. rain, etc.) and keep the fireplace dry at all times. Wet insulation
will produce an odor when the fireplace is used.
WARNING!
This fireplace is tested and listed for use only with the optional accessories listed in these instructions. Use of
optional accessories not specifically tested for this appliance could void the warranty and/or result in a safety
hazard.
Safety Precautions
1. Please read these installation instructions completely before beginning installation procedures. Failure to follow
them could cause a fireplace malfunction resulting in serious injury and/or property damage.
2. Always check your local building codes prior to installation. The installation must comply with all local, regional,
state and national codes and regulations.
3. An adequate supply of replacement combustion air from outside the house must be available to the fire for the
fireplace to operate properly. To achieve this, the use of the optional outside air kit is highly recommended.
In the event the home is unusually tightly sealed, the optional combustion air kit may not provide all the air required
to support combustion. Hearth & Home Technologies is not responsible for any smoking or related problems that
may result from the lack of adequate combustion air. It is the responsibility of the builder/contractor to ensure that
adequate combustion air has been provided for the fireplace.
4. The fireplace must be installed with the Hearth & Home Technologies SL Series Chimney System.
The chimney system must always terminate outside the building. Be sure to follow all chimney specifications given
in these installation instructions.
5. NEVER leave children unattended when there is a fire burning in the fireplace.
6. This fireplace is built for solid fuel only. NEVER use gasoline, gasoline type lantern fuel, kerosene, charcoal light
fluid, or similar liquids in this fireplace. Keep any flammable liquids a safe distance from the fireplace.
7. DO NOT use chimney cleaners or flame colorants in your fireplace.
8. The flue damper must be open at all times when the fireplace is in use.
9. While servicing this fireplace, always shut off any electricity or gas to the fireplace. This will prevent possible electric
shock or burns. Also, make sure the fireplace is completely cooled before servicing.
10. To ensure a safe fireplace system and to prevent the build up of soot and creosote, inspect and clean the fireplace
and chimney prior to use and periodically during the burning season. See “Maintenance Instructions” in this manual
for cleaning instructions.

EC SERIES INSTALLATION INSTRUCTIONS
DESIGN AND INSTALLATION CONSIDERATIONS
When selecting a location for your woodburning fireplace, it is important to evaluate a number of considerations. Modern
construction techniques can create conditions that may not allow your chimney to draft properly. This may result in
smoke spillage from your fireplace, as well as cause other combustion appliances to operate incorrectly.
Tightly sealed construction is important for energy efficiency. Unfortunately, a great deal of effort has been directed to
tightening up sidewall construction, while considerably less attention has been paid to tightening upper portions of the
warm air envelope (insulated ceilings). This has increased the “Stack Effect”, a condition that increases the negative
pressure generated by the structure. This negative pressure will directly affect the drafting performance of a fireplace
chimney. To minimize the negative pressure generated by stack effect, make certain that all duct work installed in the attic
spaces is sealed airtight. Minimize the number of recessed light fixtures installed in the insulated ceiling, and use sealed
recessed light fixtures. Finally, make certain the whole house fans and attic access panels are tightly sealed. These are
important design considerations that must be observed during the design and construction stage of the home.
If you desire to put a fireplace in your basement, we recommend that you consider a direct vent gas fireplace. Basements
always have a significant negative air pressure that causes the fireplace system to be more susceptible to smoke
spillage and cold flue back drafting. Since direct vent gas fireplaces are sealed, they are not affected by the negative
pressure that exists in basements.
Finally, woodburning fireplaces perform best when their chimney (roof termination) is located on the upper half of the
roof, especially when cathedral ceilings are present. Chimneys that are located on the lower half of the roof realize what
is known as “lazy flue” and will not draft as well as a chimney that is located in the upper portion of the roof. The reason
for this is that the stack effect generated by the overall height of the living spaces inside the house will exceed the draft
generated by the chimney system. If you desire to place a woodburning fireplace in a location where the termination cap
would be located on the lower half of a roof, such as on an outside wall at the base of a cathedral ceiling, we recommend
that you consider using a direct vent gas fireplace. This will assure the homeowner a fireplace that operates correctly.
These properties do not affect just your woodburning factory built fireplace. They can cause any woodburning fireplace as
well as any conventionally vented (B-vent) gas appliance to operate improperly. Careful planning at this stage of your
project will ensure satisfaction with the operation of your fireplace once it is completed.

A. LISTINGS AND CODE APPROVALS
This fireplace system has been tested and listed in
accordance with UL127 and ULC-S610 standards, and has
been listed by Underwriters Laboratories Inc. for installation
and operation in the United States and Canada as described
in this manual.
This fireplace has been tested and listed for use with the
optional components listed on page 5. These optional
components may be purchased separately and installed
at a later date. However, installation of an outside air kit
will require significant reconstruction, and should be
installed at the time of the initial fireplace installation.
WARNING!
This fireplace and its components are designed to be installed and operated as a system. Any alteration to or
substitution for items in this system, unless allowed by these installation instructions, will void the Underwriters Laboratories listing and may void the product warranty. It may also create a hazardous installation. Read
through these instructions thoroughly before starting your installation and follow them carefully throughout
your project.
Check with your local building code agency prior to
installing this fireplace to ensure compliance with local
codes, including the need for permits and follow-up
inspections. If you need assistance during installation,
please contact your local dealer or the Heatilator Technical
Services Department, Hearth & Home Technologies Inc.,
1915 W. Saunders St., Mt. Pleasant, Iowa 52641

D. PRE-INSTALLATION PREPARATION
1. Fireplace Locations and Space Requirements
Several options are available to you when choosing a location for your fireplace. This fireplace may be used as a
room divider, installed along a wall, across a corner or used in an exterior chase. See Figure 2.
Locating the fireplace in a basement, near frequently opened doors, central heat outlets or returns, or other locations
of considerable air movement can affect the performance and cause intermittent smoke spillage from the front of the
fireplace. Consideration should be given to these factors before deciding on a location.
CLEARANCES!
A minimum 1/2 in. air
clearance must be
maintained at the back and
sides of the fireplace
assembly.
Chimney sections at any level
require a 2 in. minimum air
space clearance between the

Figures 3 and 4 show two typical installations assuming an outside air kit is
being used. Therefore, an allowance must be made for 90-deg bends. Less
space is required when ducting goes directly outside without forming elbows.

WARNING!
Do not draw outside air from garage spaces. Exhaust products of gasoline engines are hazardous.
Do not install outside air ducts such that the air may be drawn from attic spaces, basements or above the
roofing where other heating appliances or fans and chimneys exhaust or utilize air. These precautions will
reduce the possibility of fireplace smoking or air flow reversal.
WARNING!
To prevent contact with sagging or loose insulation, the fireplace must not be installed against vapor barriers
or exposed insulation. Localized overheating could occur and a fire could result.
