Chimney Connector:
It is also known as flue pipe or stove pipe.  It must be 6 

inches (152mm) minimum diameter stainless steel connector

pipe.
Chimney:
The chimney can be new or existing, masonry or prefabricated

and  must  meet  the  following  minimum  requirements  as 

specified in Section 5B below.

In  Canada,  installations  into  factory-built  zero  clearance

fireplaces are 

NOT allowed.

Prefabricated Metal Chimney
 • Must  be  a  6  inch  (152mm)  inside  diameter  of  high

temperature chimney listed to UL 10 HT (100

o

F) or 

ULC S68.

  • Must use components required by the manufacturer for 

installation.

  • Must maintain clearances required by the manufacturer 

for installation.

 • Refer to manufacturers instructions for installation

Approved Masonry Chimney:
  • Must meet minimum standards of NFPA 11.
  • Must have at least 5/8” (16mm) fireclay lining joined with 

refractory cement.   (Installations into a clay flue without 

a  stainless  steel  liner  may  reduce  draw  which  affects

performance, will cause the glass to darken and produce 

excessive creosote).

 • Cross-sectional area should be no more than 3 times the

cross-sectional area of the flue collar of the insert.  (8 sq 

inch flue area x  inches = 8 square inches maximum 

chimney area).

 • Should be lined with a 6 inch (152mm) stainless steel

flue liner to improve performance and reduce creosote 

build-up.

 • No dilution air is allowed to enter the chimney.

   1. Seal  damper  area  of  chimney  around  chimney

connector,  or  seal  insert  against  the  face  of  the

fireplace.

   2. Both methods must be removable and replaceable

for cleaning and re-installation.

 • When possible, install an airtight clean-out door to the

rear of the smoke shelf.

Inspections
Existing chimneys should be inspected and cleaned by a

qualified  professional  prior  to  installation.    The  chimney 

must not have cracks, loose mortar or other signs of dete-

rioration  and  blockage.    Hearth  &  Home  recommends  a 

NFI  or  CSIA  certified  professional  or  a  technician,  under 

the direction of a certified professional, conduct a Level II 

inspection per NFPA 11.
Larger Chimneys
It  is  recommended  that  chimneys  with  larger  diameters

than 6 inches (15mm) be relined.  An oversized flue can 

affect draft and impair performance and will allow increased

build-up of creosote.
Chimney Height / Rise and Run
This  product  was  designed  for  and  tested  on  a  6  inch

(152mm) chimney, 14 to 16 feet (428-488cm) high, measured

from the base of the appliance.  The further your stack height 

or diameter varies from this configuration, the possibility of 

performance problems exists.
Chimney height may need to be increased by 2 - 3% per

each 1000 feet above sea level. It is not recommended to

use offsets or elbows at altitudes above 4000 feet above sea

level or when there are other factors that affect flue draft.

•  Chimney must be in good condition.
•  Meets minimum standard of NFPA 11
