8.4.2  Why the chimney should penetrate the highest heated space 

When  it  is  cold  outside,  the  warm  air  in  the  house  is  buoyant  so  it  tends  to  rise.  This 
tendency of warm air to rise creates a slight pressure difference in the house. Called ‘stack 
effect’, it produces a slightly negative pressure low in the house (relative to outside) and a 
slightly  positive  pressure  zone  high  in  the  house.  If  there  is  no  fire  burning  in  a  heater 
connected  to  a  chimney  that  is  shorter  than  the  warm  space  inside  the  house,  the  slight 
negative  pressure  low  in  the  house  will  compete  against  the  desired  upward  flow  in  the 
chimney. 

There  are  two  reasons  why  the 
chimney  in  the  house  at  right  will 
cold  backdraft  when  it  is  cold 
outside  and  there  is  no  fire 
burning  in  the  stove.  First,  the 
chimney  runs  up  the  outside  of 
the house, so the air in it is colder 
and  denser  than  the  warm  air  in 
the  house.  And  second,  the 
chimney  is  shorter  than  the 
heated  space  of  the  house, 
meaning  the  negative  pressure 
low  in  the  house  will  pull  outside 
air down the chimney, through the 
stove and into the room. Even the 
finest  stove  will  not  work  well 
when connected to this chimney. 

 

 

8.5  Supply of Combustion Air 

In Canada, wood stoves are not required to have a supply of combustion air from outdoors 
(except  in  mobile  homes)  because  research  has  shown  that  these  supplies  do  not  give 
protection  against  house  depressurization  and  may  fail  to  supply  combustion  air  during 
windy  weather.  However,  to  protect  against  the  risk  of  smoke  spillage  due  to  house 
depressurization,  a  carbon  monoxide  (CO)  detector/alarm  is  required  in  the  room  in 
which  the  stove  is  installed.  The  CO  detector  will  provide  warning  if  for  any  reason  the 
wood stove fails to function correctly.
