The venting system consists of:

•  A chimney connector (also known as fl ue or stove pipe) 
•  A chimney
•  Thimble

These  get  extremely  hot  during  use.   Temperatures  inside 
the chimney may exceed 2000°F (1100°C) in the event of a 
creosote fi re.

To protect against the possibility of a house fi re:

•  Chimney  connector  and  chimney  must  be  properly 

•  An approved thimble must be used when a connection is 

made through a combustible wall to a chimney.

•  A  chimney  support  package  must  be  used  when  a 

connection is made through the ceiling to a factory built 
chimney.

•  An approved thimble and chimney support package are 

absolutely  necessary  to  provide  safe  clearances  to 

combustible wall and

 

ceiling material.

•  The chimney connector joins the stove to the chimney.

•  It must be a 6 inch (152mm) minimum diameter 24 gauge 

mild steel black or 26 gauge blued steel.

•  Or an approved air-insulated double wall venting pipe. 

Single wall connector or stove pipe

•  Must  be  at  least  24  gauge  mild  steel  or  26  gauge  blue 

steel.

•  Sections must be attached to the appliance and to each 

other  with  the  crimped  (male)  end  pointing  toward  the 
stove.

•  All joints, including the connection at the fl ue collar, should 

be secured with 3 sheet metal screws.

•  Follow the minimum clearances to combustibles

Factory-built chimney connector (vented)

•  A Listed connector (vented) must be used when installing 

this unit in a mobile home.  

•  The  Listed  connectors  must  conform  to  each  other  to 

ensure a proper fi t and seal.

A  thimble  is  a  manufactured  or  site-constructed  device 
installed  in  combustible  walls  through  which  the  chimney 
connector passes to the chimney.

•  It is intended to keep the walls from igniting.
•  Site  constructed  thimbles  must  meet  NFPA  211 

Standards.

•   Factory-built  must  be  suitable  for  use  with  selected 

chimney and meet UL103 Type HT Standards.

•  Follow  instructions  provided  by  the  manufacturer  for 

manufactured thimbles for masonry chimney and factory- 
built chimneys.

NOTICE:  Where passage through the wall, or partition 
of  combustible  construction  is  desired  in  Canada,  the 
installation shall conform to CAN/CSA-B365.

•  This  product  was  designed  for  and  tested  on  a  6  inch 

(152mm) chimney, 14 to 16 feet (427-487cm) high, (in-
cludes appliance height) measured from the base of the 
appliance.

•  The further your stack height or diameter varies from this 

confi guration,  the  possibility  of  performance  problems 
exists.

•  Chimney height may need to be increased by 2 - 3% per 

each 1000 feet (304.8m) above sea level.

•  It is not recommended to use offsets or elbows at altitudes 

above 4000 feet (1219.2m) above sea level or when there 
are other factors that affect fl ue draft.
