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 appliance 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.

RHW-51 FIREPLACE 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 ductwork 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 backdrafting. 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.

RHW-51 FIREPLACE INSTALLATION INSTRUCTIONS

A. LISTINGS AND CODE APPROVALS

This fireplace system has been tested and listed in accordance with UL 127 standards, and has been listed by Underwriters Laboratories Inc. for installation and operation in the United States as described in this manual.

However, installation of an outside air kit will require significant reconstruction, and should be installed at the time of the initial fireplace installation.

Check with your local building code agency prior to installing

WARNING!

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 ¾ air clearance must be maintained at the back and sides of the fireplace assembly except at the nailing flange where the clearance is ½.

Chimney sections at any level require a 2 minimum air space clearance between the framing and chimney section.

Figure 2 - Fireplace Locations

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

only.

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.
