tion and necessary clearances must be considered. The re-
place system and chimney components have been tested to
provide exibility in construction. The following gures are
the minimum distances from the base of the replace.
• Minimum overall straight height is 6 ft 4 in. if the replace
is freestanding and a minimum of 10 ft from a combustible
structure. See Figure 3.2.
• Chimney must extend 2 ft (.6 m) above any portion
of the roof within 10 ft (3 m) of the chimney. Refer to
Figure 6.1.

be used.
