MASONRY CHIMNEY
Installing your fireplace with a masonry chimney still
requires using EXCEL chimney from the top of the
fireplace to where it will connect to a listed liner that will
run up inside the masonry chimney (see Figure 11).
The stainless-steel liner should be fitted inside the clay
liner all the way to the top of the masonry chimney. It is not
meant to replace the clay liner. You can use either the
EXCEL liner or any other listed liner to ULC-S635, ULC-
S640 or UL-1777.
Special care is to be taken to make sure that you have a
good solid connection between the EXCEL chimney and
the liner. A masonry adaptor (FO-FDM7) was designed
specifically for that purpose and is available from your RSF
dealer. It will attach to the liner with 3 stainless steel rivets
(provided) and to the EXCEL chimney with 3 screws
(provided).
After mortaring in place, the connection between the
EXCEL chimney and the liner should not be visible in order
to isolate the heat released through the liner from the
fireplace enclosure.
As depicted in Figure 11, you must install at least one 18"
length of EXCEL chimney after the EXCEL chimney
elbow. The uppermost part of the EXCEL chimney - where
it enters the masonry chimney - must be a minimum of 12"
from the ceiling.
NOTE:
If the ceiling is high enough, you can install one
or more EXCEL chimney lengths directly on the fireplace
before the elbow.
If you use a flexible liner, make sure to be careful when cleaning to ensure that the stainless-steel flexible liner is
not dislodged in any way.
Using an Existing Masonry Chimney
❖
WARNING: IF YOU ARE CONSIDERING USING AN EXISTING CHIMNEY, IT MUST FIRST BE
THOROUGHLY INSPECTED BY AN AUTHORITY HAVING JURISDICTION TO DETERMINE THE FOLLOWING:
•
The masonry chimney is well constructed and fully lined, in accordance with Local Building Codes and
the National Building Code of Canada (NBC) or National Fire Protection Association chimney standard
(NFPA 211).
•
It has been thoroughly cleaned of any soot or creosote residue and inspected to determine that it is in
good working condition.
•
There is no insulation of any type in contact with the masonry chimney and there is no insulation stuffed
anywhere in the chimney.
•
All the necessary clearances around the masonry chimney, along the complete run of the chimney, are
respected as per NBC or NFPA 211. If the masonry chimney is enclosed in drywall, openings will
probably be required in order to verify clearances at all points.
•
The masonry chimney will only be used for the fireplace and no other appliance.
