Heat & Glo • EM-42 • 28324 Rev U • 02/07

Getting Started

A. Design and Installation Considerations

CAUTION

Check building codes prior to installation.

• Installation MUST comply with local, regional,

state and national codes and regulations.

• Consult insurance carrier, local building inspector,

ﬁ re ofﬁ cials or authorities having jurisdiction about restrictions, installation inspection and permits.

When planning a ﬁ replace installation, it is necessary to de- termine the following information before installing:

• Where the fireplace is to be installed. See Sections 3 and 4.

• The vent system conﬁ guration to be used. See Sections 5 and 6.

• Gas supply piping. See Section 7.

• Electrical wiring. See Section 7.

• Framing and ﬁ nishing details. See Sections 3, 6 and 8.

• Whether optional accessories—devices such as a fan, wall switch or remote control —are desired. See Section 12.

Draft is the pressure difference needed to vent ﬁ replaces successfully. Considerations for successful draft include:

• Preventing negative pressure

• Location of ﬁ replace and chimney

WARNING

Asphyxiation Risk

Negative pressure can cause spillage of combustion fumes and soot. Fire needs to draft properly for safe operation.

B. Negative Pressure

Negative pressure results from the imbalance of air available for the ﬁ replace to operate properly. Causes for this imbalance include:

• Exhaust fans (kitchen, bath, etc.).

• Range hoods.

• Combustion air requirements for furnaces, water heaters and other combustion appliances.

• Clothes dryers.

• Location of return-air vents to furnace or air conditioning.

• Imbalances of the HVAC air handling system.

• Upper level air leaks: recessed lighting, attic hatch opening, duct leaks.

To minimize the effects of negative air pressure, the following must be considered:

• Install the outside air kit. Install the intake on the side of the house towards prevailing winds during the heating season.

• Ensure adequate outdoor air is supplied for combustion appliances and exhaust equipment.

• Ensure furnace and air conditioning return vents are not located in the immediate vicinity of the ﬁ replace.

• Avoid installing the ﬁ replace near doors, walkways or small isolated spaces.

• Recessed lighting should be a “sealed can” design; attic hatches weather stripped or sealed; attic mounted duct work and air handler joints and seams taped or sealed.

• Basement installations should be avoided due to stack effect. Stack effect creates negative pressure in lower levels. Hearth & Home Technologies recommends the use of direct vent ﬁ replaces in basements.

Heat & Glo • EM-42 • 28324 Rev U • 02/07

Location of the ﬁ replace and chimney will affect performance. As shown in Figure 2.1 the chimney should:

• Be installed through the warm airspace enclosed by the building envelope. This helps to produce more draft, especially during lighting and die-down of the ﬁ re.

• Penetrate the highest part of the roof. This minimizes the effects of wind turbulence.

• Be located away from trees, adjacent structures, uneven roof lines and other obstructions.

Offsets can restrict draft so their use should be minimized. Consider the ﬁ replace location relative to ﬂ oor and ceiling and attic joists.

E. Construct the Chase

A chase is a vertical boxlike structure built to enclose the A chase is a vertical boxlike structure built to enclose the ﬁ re- place and/or its vent system. Vertical chimneys that run on the outside of a building must be installed inside a chase.

Construction of the chase may vary with the type of building. These instructions are not substitutes for the requirements of local building codes. Local building codes MUST be checked.

Chases should be constructed in the manner of all outside walls of the home to prevent cold air drafting problems. The chase should not break the outside building envelope in any manner. All outer walls need to be insulated.

Building codes require false ceiling and ceiling ﬁ restops at each ﬂ oor of the chase or every 10 ft (3.05 m) of clear space to control spread of ﬁ re.

Walls, ceiling, base plate and cantilever ﬂ oor at the ﬁ rst level of the chase should be insulated. See Figure 3.5. Vapor and air inﬁ ltration barriers should be installed in the chase as per regional codes for the rest of the home. Additionally, Hearth & Home Technologies recommends that the inside surfaces be sheet rocked and taped (or the use of an equivalent method) for maximum air tightness.

Gas line holes and other openings should be caulked with high temperature caulk or stuffed with unfaced ﬁ berglass in- sulation. If the ﬁ replace is being installed on a cement slab, we recommend that in cold climates, a sheet of plywood or other raised platform be placed underneath to prevent conducting cold up into the room.

Three examples of chase applications are shown in Figure 3.6.

1. Fireplace and chimney enclosed in an exterior chase.

2. Chimney offset through exterior wall and enclosed in chase.

3. Chase constructed on roof.

All outside walls should be insulated.

Installation of Fireplace

CAUTION

Sharp Edges

• Wear protective gloves and safety glasses during installation.

A. Install the Outside Air Kit

This ﬁ replace will operate correctly only if adequate ventila- tion is provided to allow proper draft to the ﬁ replace system. See Section 2.

The outside air kit is supplied with this ﬁ replace. Using an outside air kit is highly recommended to minimize the effects of negative pressure within the structure. We recommend you utilize the shortest duct run to optimize the performance of the outside air kit. Cold air ﬂ ow can be minimized by put- ting a small dip in the duct creating a cold air trap. This trap can also help prevent heat build-up and exhausting out the intake due to the stack effect. The outside air kit inlet should be positioned in a manner that will not allow snow, leaves, etc. to block the inlet. In some installations the air duct may need to be run vertically. In such an installation, a 3 ft (.914 m) height difference must be maintained from the top of the uppermost chimney section to the outside combustion air inlet. See Figure 4.2.

WARNING

Fire Risk Asphyxiation Risk

Do not draw outside combustion air from:

• Wall, ﬂ oor or ceiling cavity.

• Enclosed space such as an attic or garage.

• Close proximity to exhaust vents or chimneys.

Fumes or odor may result.

CAUTION

Risk of Smoke Spillage

Outside air inlet must be located to prevent blockage from:

• Leaves

• Snow/ice

• Other debris Blockage may cause combustion air starvation.

The outside air kit is installed on the right hand side of the ﬁ replace. Remove the insulation in the tube, slide tube out to fasten duct to it. See Figure 4.1.

Included with your ﬁ replace you will ﬁ nd two metal hearth strips measuring approximately 26 in. x 4 in. (660 mm x 102 mm). These strips are used to provide added protection where the ﬁ replace and the hearth ex- tension meet.

Slide each metal strip 2 in. (51 mm) under the front edge of the ﬁ replace. The individual pieces must over- lap each other by 1 in. (25 mm) minimum in the middle of the ﬁ replace to provide continuous coverage of the ﬂ oor. See Figure 4.5. These metal strips should extend from the front and sides of the ﬁ replace opening by 2 in. (51 mm).

Note: When elevating the ﬁ replace above the hearth exten- sion the front of the elevated platform must be protected with a protective metal hearth strip as shown in Figure 4.6.

Metal strips are placed 2 in. (51 mm) under the front of the fireplace and must extend beyond the front and sides of fireplace opening by 2 in. (51 mm).

• Level the Fireplace

Level the ﬁ replace side-to-side and front-to-back. Shim with noncombustible material, such as sheet metal, as necessary. Secure the ﬁ replace (using the nailing ﬂ ang- es located on either side of the ﬁ replace) to the vertical framing.

Important: To e n s u r e p r oper ﬁ t of the glass doors, check the ﬁ replace opening for square. Measure diagonal dis- tances of the opening to make sure they are equal. If they are not, continue to shim the ﬁ replace until those diagonals are equal.
