originating in the fireplace enclosure. If you follow this procedure, we recommend that you do not insulate the wall
above the front of the fireplace.
REMEMBER:
Check local codes concerning installation requirements and restrictions in your area.
MASONRY CHIMNEY
Installing your DELTA FUSION fireplace with a masonry chimney still requires using EXCEL chimney from the top
of the fireplace to the wall where it will connect to a listed liner that will run up inside the masonry chimney (see
Figure 12).
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-FDM8) 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 12, 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:
1. 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).
2. It has been thoroughly cleaned of any soot or creosote residue and inspected to determine that it is in good
working condition.
3. There is no insulation of any type in contact with the masonry chimney and there is no insulation stuffed
anywhere in the chimney.
4. 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.
5. The masonry chimney will only be used for the fireplace and no other appliance.
If major repairs are required to meet the above conditions, a new chimney should be constructed.
