Typical Installation
-Refer to our Typical Venting Installation drawings to select the appropriate component parts for your installation. For more Typical Installations kindly check our download links below.
Planning Your Installation:
- For vertical gas stove installations, measure the height from the stove outlet to the ceiling to determine the length of black pipe required. Select a ceiling support/wall thimble cover or a cathedral ceiling support box.
- To determine the length of galvanized pipe required, measure the ceiling thickness and the vertical rise in an attic or second story. Firestops are required at each floor level beyond the first-floor ceiling support/wall thimble cover or cathedral ceiling support box. If an offset is required to avoid obstructions, use a pair of 45° elbows. For proper support, use elbow straps with offsets. Use wall straps for long vertical runs. An attic Insulation Shield is required in the attic.
- Measure the roof pitch. Select the proper flashing and storm collar. Determine the minimum height above the roof.
- For horizontal installations, check the appliance manufacturer’s instructions for the minimum rise and maximum horizontal run. A snorkel termination may be used if height restrictions prevent adequate rise above the appliance. Select the appropriate Horizontal Termination Cap (see appliance manufacturer installation instructions). To protect vinyl siding, select vinyl siding standoff. Check appliance manufacturer’s instructions for wall thimble and firestop requirements.
Design Recommendations
-
The following design recommendations are general guidelines to assist in the design and selection of venting components for your installation. Always follow DuraVent Installation instructions enclosed with the cap or support box before installing your chimney system. Installation instructions can be viewed online at www.duravent.com, under Catalogs and Instructions. Important: Check the manufacturer’s rating plate and instruction manual to confirm that the DuraVent direct vent system is approved for use on the brand-name appliance you have selected.
-
The inner and outer pipe diameters should match the outlet size of the appliance.
-
Check the appliance manufacturer’s installation instructions to confirm which types of vent configurations are permitted (i.e. horizontal, vertical, chimney reline, etc.). Also, check for any venting restrictions such as maximum horizontal run, minimum and maximum vertical rise, maximum offset, etc.
-
Be fire safe! Maintain at least the minimum clearances (air-space) between the vent pipe and nearby combustibles, as specified in the appliance manufacturer’s installation instructions. Use proper support and bracing. Follow local building codes and have your venting system inspected.
