1.  Install the 4” inner collar by first 

placing the 4” x 6” gasket ring onto 
the base of the collar. Install the 
collar and gasket to the stove using 8 
of the screws provided. 

2.  Install the outer collar in similar 

fashion using the larger gasket ring 
and the remaining 8 screws. 

3.  Install the 45º elbow over the outer 

collar. Place the elbow so that the 
twist lock end is pointing up. 

4.  Install one of the 9” pipe sections 

into the elbow by fully inserting it 
and turning approximately ¼ turn 
clockwise, until the 2  sections are 
fully locked. Install the 90º elbow in 
similar fashion. 

5.  Move the stove and pipe assembly 

back until the 90º elbow is flush to 
the wall. The 9” vertical pipe should 
be parallel to the wall. Draw a circle 
around the pipe. Use the center of 
this circle as the center point of the 
10” x 10” square wall pass through. 
(It should be approximately 40-1/4” 
above the floor) Cut and frame the 
wall pass through. 

6.  Place the interior wall thimble into 

the 10” x 10” wall pass through. 
Secure it with 4 screws  (not 
provided). Install the exterior portion 
of the thimble in similar fashion, 
overlapping the 2 sections.

Caution:

 For building with vinyl siding, 

a vinyl siding standoff  should be 
installed between the vent cap and the 
exterior wall. Refer to venting 
manufacturer’s Instructions for Direct 
Vent Heaters for installation instructions. 

7.  Install the horizontal vent 

termination on the outside of the 
wall. Make sure both of the retaining 
straps extend through interior wall 
thimble. Before attaching the vent 
termination to the outside of the 
house, run a bead of non-hardening 
mastic around its’ outside edges, so 
as to make a seal between it and the 
wall. The arrow on the end cap 
should point up. Secure the cap to 
the wall with the appropriate screws. 

8.  Place the thimble cover onto the 90º 

elbow. Put the 9” pipe into the 
horizontal vent cap, (the vent pipe 
must extend into the horizontal vent 
cap a minimum of 1-1/4”). Move the 
stove and vent pipe into position, 
insert the 9” pipe into the 90º elbow 
and twist  to lock it. Secure the straps 
from the horizontal vent termination 
to the interior pipe with 2 sheet metal 
screws, keeping screws close to wall 
thimble as possible. Bend or cut the 
excess strapping so that the thimble 
cover will fit properly. Screw the 
thimble cover to the wall.
