Bought this unit as backup for a twenty plus year old unit in a woodstove flue pipe. Old unit removed two or three times a year and creosote removed. Motor getting tired and getting hard to restart. Decided to install new unit and move old unit to backup.Old unit installed securely with four corner screws, three side screws, and two top screws. New unit - only four (now much smaller) corner screws. Enlarged four corner holes to work with old unit corner screws. Drilled 5 new holes for three side screws and two top screws. Now installed in place of old unit. Other than mounting holes, new unit seems identical to old, twenty plus year old unit. Now securely installed and running perfectly. Well designed, well constructed unit. Solid Scandinavian (most likely Dansk!). Great device for wood stove with poor natural draft.
