- Negative house pressures can pull the smoke from one flue down another flue right beside it. Adding the Flue Stretcher to the upstairs flue distances its smoke from the downward pull of the downstairs flue.
- By putting the flue opening above roofs and other nearby structures you will improve draft and reduce downdrafts.
The Flue Stretcher easily tightens with screws to the flue tile on all four sides of the base for extra security. Load test simulating side wind and updraft conditions have demonstrated the Flue Stretcher mounting system holds tight under several hundred pounds of force.
