Install Guide
2 Getting Started
A. Design and Installation Considerations
Before installing, determine the following:
• Type of chimney connector to be used
- Single wall, 6 inch (152mm) diameter, stainless
steel, or
- Double wall, 6 inch (152mm) diameter, stainless
steel
• Consult page 28 for clearances to combustibles
• Power outlet located close by for optional blower
Draft is the pressure difference needed to vent appliances
successfully. When a appliance is drafting successfully, all
combustion byproducts are exiting the home through the
chimney.
Considerations for successful draft include:
• Preventing negative pressure
• Location of appliance and chimney
To be sure that your appliance burns properly:
• During a low burn, the chimney draft (static pressure)
should be approximately -.04 inch water column (W.C.)
• During a high burn the chimney draft should be
approximately -.10 inch (W.C.)
• Measure the W.C at 6 inches (152mm) above the top
of the appliance after one hour of operation at each
burn setting.
B. Draft
Check building codes prior to installation.
• Installation MUST comply with local, regional, state
and national codes and regulations.
• Consult insurance carrier, local building, re ofcials
or authorities having jurisdiction about restrictions,
installation inspection, and permits.
CAUTION
WARNING
Asphyxiation Risk.
• Do NOT connect this appliance to a
chimney ue servicing another appliance.
• Do NOT connect to any air distribution duct
or system.
May allow ue gases to enter the house.
NOTICE: Hearth & Home Technologies assumes no
responsibility for the improper performance of
the appliance system caused by:
• Inadequate draft due to environmental conditions
• Down drafts
• Tight sealing construction of the structure
• Mechanical exhausting devices
• Over drafting caused by excessive chimney heights
• Ideal performance is with height of chimney between
14-16 feet (4.26-4.88m) measured from the base of
the appliance.

WARNING
Fire Risk.
Hearth & Home Technologies disclaims any
responsibility for, and the warranty will be voided
by, the following actions:
• Installation and use of any damaged appliance.
• Modication of the appliance.
• Installation other than as instructed by Hearth &
Home Technologies.
• Installation and/or use of any component part not
approved by Hearth & Home Technologies.
• Operating appliance without fully assembling all
components.
• Operating appliance without legs attached (if supplied
with appliance).
• Do NOT Over re - If appliance or chimney connector
glows, you are over ring.
Any such action that may cause a re hazard.
D. Tools And Supplies Needed
Before beginning the installation be sure the following tools
and building supplies are available:
Reciprocating saw
Framing material
Pliers
High temp caulking material
Hammer
Gloves
Phillips screwdriver
Framing square
• Remove appliance and components from packaging
and inspect for damage.
• Report to your dealer any parts damaged in shipment.

installation. Follow these instructions carefully
during the installation to ensure maximum safety
and benet.
E. Inspection of Appliance and Components
Flat blade screwdriver
Electric drill and bits
Plumb line
Safety glasses
Level
Tape measure
Misc. screws and nails
7/16 socket or wrench
1/2-3/4 in. length, #6 or #8 self-drilling screws
Fire Risk.
Inspect appliance and components for damage.
Damaged parts may impair safe operation.
• Do NOT install damaged components.
• Do NOT install incomplete components.
• Do NOT install substitute components.
Report damaged parts to dealer.
WARNING
C. Negative Pressure
Negative pressure results from the imbalance of air
available for the appliance to operate properly. It can be
strongest in lower levels of the house.
Causes include:
• Exhaust fans (kitchen, bath, etc.)
• Range hoods
• Combustion air requirements for furnaces, water
appliances 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 such as:
- Recessed lighting
- Attic hatch
- Duct leaks
To minimize the effects of negative air pressure:
• Install optional outside air kit with the intake facing
prevailing winds during the heating season
• Ensure adequate outdoor air for all combustion
appliances and exhaust equipment
• Ensure furnace and air conditioning return vents are
not located in the immediate vicinity of the appliance
• Avoid installing the appliance 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
WARNING
Asphyxiation Risk.
• Negative pressure can cause spillage
of combustion fumes, soot and carbon
monoxide.
• Appliance needs to draft properly for
safety.

C. Calculating Alternate Floor Protection
Material
Thermal Resistance: R value
The R value is a measure of a material’s resistance to heat
transfer.
R value is convenient when more than one material is used
since you can add the R values together, whereas you can
not do this for k value.
The HIGHER the R factor means less heat is being
conducted through the non-combustible material to the
combustible material beneath it.
The R value of a material must be equal or larger then the
required R value to be acceptable.
