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.

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

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

•  DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE 

SERVICING ANOTHER APPLIANCE.

•  DO NOT CONNECT TO ANY AIR DISTRIBUTON DUCT 

OR SYSTEM.
