Minimum clearance between vent pipes and combustible materials is 3¹⁄₂” (89 mm) on top, 2¹⁄₂” (64 mm) on both sides and 1¹⁄₂” (38 mm) on the bottom.
When the vent termination exits through foundations less than 20” (508 mm) below siding outcrop, the vent pipe must be flush with the siding.
It is always best to locate the fireplace in such a way that minimizes the number of offsets and horizontal vent length of vent pipe from the flue collar of the fire- place to the face of the outer wall.
Horizontal plane means no vertical rise exists on this portion of the vent assembly.

Sidewall Applications
Since it is very important that the vent- ing system maintain its balance between
the combustion air intake and the flue gas exhaust, certain limitations as to vent configurations apply and must be strictly adhered to.
NOTE: The penetration to the outside of the build- ing or structure shall be sealed air and weather tight.
Use of the Restrictor Plates in
Horizontal Venting Applications
The primary purpose for the vent restrictor plate is to regain flame height under certain venting conditions as outlined below.
The DVT38IN is shipped with the fresh air plate set- tings at #4 (this applies to both natural gas and propane) when using the horizontal starter vent kit SK8DVSK.
• A minimum of 2’ (610 mm) vertical section off the top |
of the unit is required, an elbow and a 1’ (305 mm) |
maximum horizontal run to get through a wall. (Fig. |
