2 Getting Started
A. Design and Installation Considerations
Draft is the pressure difference needed to vent replaces
successfully.Considerationsforsuccessfuldraftinclude:
• Preventing negative pressure
• Locationofreplaceandchimney
B. Negative Pressure
Negative pressure results from the imbalance of air avail-
able for the 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.
Asphyxiation Risk
Negative pressure can cause spillage of
combustion fumes and soot. Fire needs to draft
properly for safe operation.
WARNING
Check building codes prior to installation.
• Installation MUST comply with local, regional,
state and national codes and regulations.
• Consult insurance carrier, local building inspector,
reofcialsorauthoritieshavingjurisdictionabout
restrictions, installation inspection and permits.
CAUTION
Whenplanninga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congurationtobeused.SeeSections
5 and 6.
• Electrical wiring. See Section 3.
• Framingandnishingdetails.SeeSections3,6and8.
• Whether optional accessories are desired. See
Section 12.
TheConstitutionFireplacerequiresaminimumuedraftof
-0.10 inches of water column on High, and -0.04 inches of
watercolumnonLow,asmeasuredwithadraftmeter.Most
dealershavedraftmetersavailabletomeasureyouruedraft
if you suspect a problem.
Ifthereisdifculttostart,andsmokespillsoutofthedoor,
or you nd it hard to establish and maintain a moderately
highburnrate,thentheuedraftistoolowandcorrective
measures must be taken.
NOTE: Cold air inltration can cause frosting on glass.
• Upper level air leaks: recessed lighting, attic hatch
opening, duct leaks.
To minimize the effects of negative air pressure, the follow-
ingmustbeconsidered:
• Install the outside air kit.
• 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replace.
• Avoidinstallingthe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.
Locationofthereplaceandchimneywillaffectperformance.
AsshowninFigure7.1,onpage7,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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 replace location relative to oor and ceiling
and attic joists.

E. Construct the Chase
Achaseisaverticalboxlikestructurebuilttoenclosethere-
placeand/oritsventsystem.Verticalchimneysthatrunon
the outside of a building must be installed inside a chase.
In cold climates, it is recommended that the chase insulated
using batt type insulation between the joists.
Construction of the chase may vary with the type of build-
ing. These instructions are not substitutes for the require-
ments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restopsat
each oor of the chase or every 10 ft (3048 mm) of clear
spacetocontrolspreadofre.
Walls,ceiling,baseplateandcantileveroorattherstlevel
of the chase should be insulated. See Figure 14.1. Vapor
andairin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 equiv-
alent method) for maximum air tightness.
Holes and other openings should be caulked with high tem-
peraturecaulkorstuffedwithunfacedberglassinsulation.

Materials
a. The chase is constructed using framing materials
much the same as the walls in your home. A variety
of siding materials may be used including brick, stone,
veneer brick, or standard siding materials.
b. In constructing the chase, several factors must be
considered:
1) Maintaina2in.(51mm)airspacearoundthe
chimney.
2) The chase top must be constructed of non-com-
bustible material.
3) In cold climates, a restop spacer should be

This reduces heat loss through the chase.
4) In cold climates, the walls of the chase should
be insulated to the level of the false ceiling as
shown in Figure 14.1. This will help reduce heat
lossfromthehomearoundthereplace.

A. Install the Outside Air Kit
Thisreplacewilloperatecorrectlyonlyifadequateventila-
tionisprovidedtoallowproperdrafttothereplacesystem.
See Section 2.
Using an outside air kit must be used for combustion to mini-
mize 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. 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 mm) height difference must be maintained from the
top of the uppermost chimney section to the outside com-
bustion air inlet. See Figure 16.1 on page 16.
See Figure 17.1 on page 17 for proper placement of outside
air inlet.
The outside air kit is installed on the right hand side of the
replace.SeeFigure15.1forhandlelocation/operation.

Figure 15.1 Outside Air Installation
1. Cut a 6 in. (152 mm) hole in outside wall to accommodate
air piping. The outside air is located on top, auxiliary
convection air intake is located on the bottom. See Figure

2. Use6in.(152mm)metalexorrigidpiping(not supplied)
todirectlyconnectoutsideairtoreplaceintake.Insulate
the pipe to prevent frost condensation.
3. Use the supplied termination caps.
4. Seal between the wall and the pipe with silicone to prevent
moisture penetration and air leaks.
5. Seal between the termination cap and the house with
siliconetopreventairinltration.
NOTE: A control knob allows you control of the outside air
inlet. Use of outside air for combustion is required to
conserve heated air within the structure and to provide
makeupairtokeepthereplaceventingproperly.
