Figure #6.1: Minimum Chimney Height 

Installation with an 7 in. EXCEL chimney 

Installing your 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. 

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 or flexible liner 
to ULC-S635, ULC-S640 or UL777. 

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 specially for that purpose and is available from 
your RSF dealer. It will attach to the liner with 3 stainless 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. 

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.

To make the hole through the masonry chimney and make the connection to the fireplace, we recommend 
that you follow these steps: 

1.  Sight-in and mark the outline of where the EXCEL chimney will penetrate the masonry chimney. 

2.  Using a large (3/4”-2”) masonry drill bit, drill a hole exactly in the center of the oval outline. With a 

masonry hammer and drill, slowly enlarge the hole to the size required. Remember to work from the center 
out. Be especially careful with the clay liner behind the brick because three sides of it must stay in place.
