Basement Installations
To achieve the minimum vertical rise a 36” snorkel must be used. Where the bottom of the terminal may be blocked by snow, ensure provision is made for adequate drainage.
3.3.4.5 Vertical installation
Always maintain a 1” clearance around the vent pipe (vertical) and 2” clearance horizontal, when passing through ceilings, walls, roofs, enclosures, attic rafter or any combustible surfaces.
DO NOT PACK AIR SPACES WITH INSULATION.
Refer to the vent charts for maximum allowable vertical and horizontal allowable installations.
When planning your installation determine if ceiling joists, roof rafters or other framing will obstruct the vent system. You may have to use 45° elbows to navigate around any obstacles. When passing through a flat ceiling install a Box/Wall thimble. Cut a 10” square hole and frame as shown in the diagram opposite. Ensure all pipe sections are fully twist locked.
NOTE: ALWAYS CHECK YOUR LOCAL CODES BEFORE INSTALLING VENTING. CLEARANCES ETC, MAY VARY FROM STATE TO STATE (PROVINCE TO PROVINCE).
NOTE: CONSULT DURAVENT PARTS LIST OR SECURITY CHIMNEY PARTS LIST FOR PART NUMBERS (USE ONLY DURAVENT GS SYSTEM OR SECURITY DV PARTS).
