all openings or cutters of the highest
building located within 25 feet of such
pipe, and, securely fastened by proper
guys and supports, so as to prevent

Where this Ordinance refers to
buildings built Of one thickness OF
Ione-inch boards, this must be taken
that the main building is built of ore

roof and continue up perpendicularly
to the highest ridge of the roof. This
e however, will not apply where the
{ vents go up at right angles with the
ridge, inside the line formed by ths
t hip of roof; in this case, the vents
n shall be angled off so as to pass
the chimney and go through the root
