Osburn Stoves by SB I HYBRID-45 MF Benutzerhandbuch

 

NOTE: Follow L-Vent chimney manufacturer’s instructions. 
 
1.  Have the masonry chimney inspected by a qualified 

chimney sweep or installer to determine its structural 
condition. 

 
2.  You will need a pipe length equal to the chimney height 

from the hearth. If outside combustion air is to be used, you 
will need a pipe length equal to the chimney height plus 18 
inches. 

 
3.  Install a blanking plate and the chimney pipe, and if used 

the outside air pipe, as shown in Figure 12. 
 

4.  Attach the DuraVent adapter, a section of pipe and clean 

out tee, making sure the clean out tee is centered in the 
chimney flue area. Use RTV, metallic tape, and a minimum 
of three self-taping screws at all joint connections to ensure 
a tight seal. 
 

5.  Position the stove, adhering to the clearances in Figures 1 

& 2. 

 
6.  Measure and build chimney top plate. Cut out holes for 

chimney pipe, and if used the outside air pipe. Install and 
seal with non-hardening mastic to prevent water leakage. 
Install vent cap.

NOTE: Follow L-Vent chimney manufacturer’s instructions. 
 
1.  Position the stove, adhering to the clearances in Figures 1 

& 2. Mark the center of the hole where the pipe is to pierce 
the masonry chimney. 

 
2.  It will be necessary to break out the masonry around the 

location of the pipe center mark. Use a 4-inch diameter 
hole for 3-inch pipe and 5-inch diameter hole for 4-inch 
pipe. 

 
3.  Measure and build chimney top plate. Cut out holes for 

chimney pipe, and if used the outside air pipe. 

 
4. 

Install the tee on the bottom of the vertical pipe system and 
lower it down the chimney until the center branch of the tee 
is level with the center of the hole in the masonry, as 
shown in Figure 13. 

 
5.  Install and seal the top plate from step 3 with non-

hardening mastic. Slip the storm collar over the pipe, and 
while holding the pipe at the proper elevation, affix the 
collar with a minimum of three ¼” stainless steel sheet 
metal screws. Seal all joints and seams around the collar. 

 
6.  Connect the horizontal pipe by pushing it through the hole 

in the masonry and lining it up with the branch in the tee. 
Push the pipe into the tee while twisting it to lock it into the 
tee. 

 
7.  If desired, once the horizontal pipe is in place, the space 

between the pipe and masonry may be filled with high-
temperature grout. 

 
Install the trim collar. An adjustable pipe length and adapter may 
be needed to finish the connection to the stove.
