Getting Started
A. Design and Installation Considerations
!
Check building codes prior to installation.
• Installation MUST comply with local, regional, state
and national codes and regulations.
• Consult insurance carrier, local building, fire officials
or authorities having jurisdiction about restrictions,
installation inspection, and permits.
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, tainless steel
• Consult page 28 for clearances to combustibles
• Power outlet located close by for optional blower
!
Asphyxiation Risk.
• Do NOT connect this unit to a chimney
flue servicing another appliance.
• Do NOT connect to any air distribution
duct or system.
May allow flue gases to enter the house.
B. Draft
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 the burn, the chimney draft (static pressure)
should be approximately -0.07 inch water column (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.

CAUTION
WARNING
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.
C. Negative Pressure
Asphyxiation Risk.
• Negative pressure can cause spillage
of
carbon monoxide.
• Appliance needs to draft properly for safety.
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 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 such as:
-
Recessed lighting
-
Attic hatch
-
Duct leaks
To minimize the effects of negative air pressure:
• Install the 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
