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.

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

• Whether optional accessories are desired. See Sections
7 and 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.

Heatilator • I60 US-CAN • 4013-202 Rev F • 11/07

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 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.

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 (as an optional feature) with
this fi replace and its use 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 mini-
mized by putting 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.

See Figure 4.3 for proper placement of outside air inlet.

The outside air kit is installed on the left hand side of the
fi replace. See Figure 4.4 for handle location/operation.

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

B. Secure the Fireplace

• Position the Fireplace

This fi replace may be placed on either a combustible or
noncombustible continuous fl at surface. Follow the in-
structions for framing in Section 3.D. Slide the fi replace
into position. Be sure to provide the minimum air clear­ance at the sides and back of the fi replace assembly.
See Section 3.B.

WARNING

Fire Risk!

• Prevent contact with sagging, loose
insulation.

• Do NOT install against vapor barriers or
exposed insulation.

• Place the Protective Metal Hearth Strips

WARNING

Fire Risk!

• Metal hearth strips MUST be installed.
Sparks or embers may ignite fl ooring.

1 in. (25 mm) overlap

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).

Figure 4.5 Position the Protective Metal Hearth Strips

Top piece must overlap

bottom piece

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.

• 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.

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.
