*NOTE: Termination in an alcove space (spaces open only on one side and with an overhang) is permitted with the dimensions
specified for vinyl or non-vinyl siding and soffits. 1. There must be a 3’ (914 mm) minimum between termination caps. 2. All
mechanical air intakes within 10’ (1 m) of a termination cap must be a minimum of 3’ (914 mm) below the termination cap. 3. All
gravity air intakes within 3’ (914 mm) of a termination cap must be a minimum of 1’ (305 mm) below the termination cap.
NOTE: Refer to Page 22, Figure 35 for instructions to fabricate 3” and 4¹⁄₂” flue restrictor plates.
