Locate Chimney Centerpoint on Roof

Use same procedure detailed in locating centerpoint of 
the flue system.
Drive a nail up through roof at the centerpoint. This will 
determine center point on outside of the roof.

Cut and Frame Roof Hole

Size of roof hole varies with the type of chimney termi-
nation installed. Refer to installation instructions pro-
vided with the chimney termination to find correct size 
of roof hole.

NOTE:

 The air space dimensions in this manual 

that pertain to model 11CF chimney pipe have been 
changed from 2" to 1" (51 - 25mm) clearance for first 
joist space only. This change only applies to Majes-
tic Fireplaces models STR42 and CVR42 fireplaces. 
Because of framing concerns these models, and only 
these models, have been tested and approved at the 
reduced clearance. In all other cases the minimum air 
space referred to on the UL label on the 11CF pipe 
must be maintained. A special firestop is shipped with 
these units that will maintain the 1" (25mm) clearance 
at the first joist. The chimney hole size for this firestop 
will be 15

¹⁄₂

" (394mm). Refer to Figure 18 for ceiling 

joist installation instructions. 
There must be an air space (1

¹⁄₂

" (38mm) with SK8 and 

1"  (25mm) with 11CF) between outermost portion of 
chimney sections and any adjacent combustible sur-
faces. (Fig. 20) (Combustible surfaces include burnable 
materials such as:  ceiling members, joists, flooring, 
combustible insulation and roof structures.)

Firestop spacers are not available for nor are they re-
quired on vertical walls.

DO NOT 

put any sealant around the area where the 

outer pipe slides through the firestop spacer.  If you 
seal this area, 

it may cause a fire hazard.

Canadian Requirements 

for Insulation Shield

In Canada, an attic insulation shield is required to pre-
vent attic insulation from contacting the chimney sec-
tion. Framing dimensions for the chimney hole should 
measure 14

¹⁄₂

" x 14

¹⁄₂

" (368 x 368mm)(SK8). (An attic 

shield MUST be installed on top of attic joists (above 
the floor level). Refer to Figure 19. 
Install the attic insulation shield with the flanges on its 
base extending down into the framing hole. Nail each 
corner of attic insulation shield to the framing members 
of the ceiling hole using 8d nails.  Attic shields are not 
required at the roof.

Continue Installing Pipe to Complete Run

Continue attaching pipe sections to complete system 
to next level always being careful that the pipe is firmly 
snapped locked in place before proceeding to next pipe 
section.

Chimney Supports

If chimney supports are required, they are installed the 
same as elbows.  Nail chimney support straps to ad-
jacent structural framing, as shown on Figure 8, Page 
8. Bend straps as necessary and make sure they are 
secure so they will support the weight of the chimney. 
A chimney support is 2

¹⁄₂

" (64mm) long when installed. 

Consider this dimension when determining how many 
straight chimney sections are needed.

NOTE:

  Chimney supports are generally used in long 

runs in a chase installation. 

A chimney support can-

not be mounted directly to the fireplace.

Additional Ceilings

If you encounter additional ceilings, repeat same steps 
required for first ceiling installation.  Refer to firestop 
illustration on Page 12, Figure 18. 

Penetrating the Roof

Run pipe to roofline.  Since chimney system must be 
vented to the out-of-doors, you 

must 

use an approved 

termination.
If a chase is used, refer to the installation manual pro-
vided with the termination cap.
