Installation reminders

  • The appliance type should never change chimney installation. Even if you start with gas/oil today, the same chimney may serve solid fuel in the future.
  • Maintain minimum 2" airspace clearance to combustibles and insulation (except manufacturer-approved products like SUSI, where applicable).
  • Use locking bands or screws as required for joint security on chimney and connector components.
