Chimney Shroud
Top Open
Keep a minimum 6-inch clearance around the diameter of the cap's side edge and extending above and below the cap.
Sides Open
Keep a minimum 6-inch clearance around the diameter of the cap's side edge, and a minimum 10-inch clearance above the top of
the cap. For openings in the shroud, make sure to allow for enough air flow space to release the exhaust gases and allow the vent
to operate properly.
Vent Installation
Venting must be installed to meet the requirements as detailed in the following sections in conjunction with the vent system
manufacturer's installation instructions. Venting must be supported by the structural surrounding and not by the fireplace. Each offset
(elbow) must be strapped to reduce movement or possible disconnection.
The first section of venting must be secured to the fireplace starter collar with a minimum of 3 sheet metal screws no longer than ½".
DO NOT use silicone to seal the sections. If sealing is required by the vent manufacturer or local code, use Mil-Pac sealant.
WARNING: Do not combine vent components from different vent manufacturers. Please follow the manufacturer's
instructions for vent system installation.
Vent Maintenance
Regular inspection of the vent system by a qualified service technician is recommended every six months. The following maintenance
routing is recommended:
Inspect for excessive condensation, e.g., water droplets forming in the inner lining, and subsequently dripping from the joints.
This can cause corrosion in the system.
Check for corrosion in areas exposed to the elements. Components with rust spots or holes must be immediately replaced.
Ensure that there is no foreign material in the vents. Survey by removing the cap and shining a light down the vent.
If possible, check all vent joints to make sure nothing has been disturbed or loosened.
