C. Thermostat Location
The thermostat’s location will have some effect on the
appliance’s operation. When the thermostat is located close
to the appliance, it may require a slightly higher temperature
setting to keep the rest of the house comfortable. If the
thermostat location is in an adjacent room or on a different
fl oor level, you will notice higher temperatures near the
appliance.
CAUTION
• DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE
SERVICING ANOTHER APPLIANCE.
• DO NOT CONNECT TO ANY AIR DISTRIBUTON DUCT
OR SYSTEM.
Fire Hazard.
WARNING
• Do not operate appliance before reading
and understanding operating instructions.
• Failure to operate appliance properly may
cause a house fi re.
Location of the appliance and chimney will affect
performance.
• Install 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 loading.
• Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
• Minimize the use of chimney offsets.
• Consider the appliance location relative to fl oor and ceiling
and attic joists.
• Take into consideration the termination requirements on
Page 11.
B. Locating Your Appliance & Chimney
D. Draft
Draft is the pressure difference needed to vent appliances
successfully. When an 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
NOTICE:
Hearth & Home Technologies assumes no
responsibility for the improper performance of the chimney
system caused by:
• Inadequate
draft due to environmental conditions
• Downdrafts
• Tight sealing construction of the structure
• Mechanical
exhausting devices
E. Negative Pressure
WARNING! Risk of Asphyxiation!
Negative pressure can
cause spillage of combustion fumes and soot.
Negative pressure results from the imbalance of air avail-
able for the appliance to operate properly. It can be stron-
gest 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
