6.Slide the wall thimble over the vent pipe before con- necting the horizontal run to the vent cap. Figure 19
7.Carefully move the fireplace with vent assembly attached toward the wall and insert the vent pipe into the horizontal termination. The pipe overlap should be a minimum of 1Z\v". Apply silicone to the outer pipe connection. Fasten all vent connections with screws provided.
8.Slide the wall thimble against the interior wall surface and attach with screws. Figure 19

Since it is very important that the venting system main- tain its balance between the combustion air intake and the flue gas exhaust, certain limitations as to vent con- figurations apply and must be strictly adhered to.
The Vent Graph, showing the relationship between vertical and horizontal side wall venting, will help to determine the various dimensions allowable. Page 16
Minimum clearance between vent pipes and combus- tible materials is 3" on top and 1" from bottom and sides unless otherwise noted (Exception: Outside wall with firestop: 1" all around pipes are allowed).
When vent termination exits through foundations less than 20" below siding outcrop, the vent pipe must flush up with the siding.
It is best to locate the fireplace in such a way that minimizes the number of offsets and horizontal vent length.
The horizontal vent run refers to the total length of vent pipe from the flue collar of the fireplace (or the top of the transition elbow) to the face of the outer wall or the mount- ing flange of the termination.
