    b) their actual interior dimensions
    c) their nominal exterior dimensions
    d) their weight
    e) their ASTM classification
4) How close can a masonry chimney be to combustible material such as roof framing?
    a) 1 inch if the chimney is on the outside of the wall with three sides exposed.

    c) 8 inches
8) In seismic design zones masonry chimneys must have at least one 1/2" rebar grouted vertically in each corner of the chimney, tied horizontally with 1/4" pencil rod at least every 18" of vertical lift. Where exactly in the corners should the vertical rebar be placed?
    a) between the clay flues, if they are wrapped with insulation or ceramic paper, and the surrounding masonry
    b) within the cells of the masonry units themselves
    c) in confined spaces formed by the masonry shell and internal masonry wythes
