 • Must meet minimum standards of NFPA 211.
 • Must have at least 5/8 inch (16mm) fireclay lining joined

with refractory cement. 

  

 •

The  masonry  wall  of  the  chimney,  if  brick  or  modular

block, must be a minimum of 4 inches (102mm) nominal

thickness.

 •

A chimney of rubble stone must be at least 12 inches

(305mm) thick.

 • Cross-sectional  area  shall  conform  to  NFPA  211-2006

Section 12.4.5.1.

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

flue liner to improve performance and reduce creosote

build-up and difficulty starting a fire.

An equivalent liner must be a listed chimney liner system

or other approved material.

 • No dilution air is allowed to enter the chimney.

   1. 

Secure the fireplace damper in the open position. If

this cannot be accomplished, it will be necessary to 

remove the damper

  

   2. Seal  damper  area  of  chimney  around  chimney

connector with a high temperature sealant or seal 

insert against the face of the fireplace.

    3. 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.

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 below.

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 211.

Fire Risk
Inspection of Chimney:
•  Chimney must be in good condition.
•  Meets minimum standard of NFPA 211
•  Factory-built chimney must be 6 inch

(152mm) UL103 HT.

NOTICE:  Check  with  your  local  building  authorities

and/or consult the National Fire Protection Association

(NFPA 211).

Hearth  &  Home  recommends  that  chimneys  with  larger

diameters than 6 inches (152mm) be fully relined. An over-

sized flue can affect draft and impair performance and will

allow increased build-up of creosote which is why a full reline 

is stongly recommended.

NOTE: Masonry chimneys are significantly less than ideal

for venting solid fuel appliances. A masonry chimney is not

subject to any temperature limit test, therefore a full reline

is strongly recommended.
