Next look on the Vertical Installation ChartTable 2 to determine the piecesof pipe required forthe desired height. A 23 ft. in

stallation requires 5 sections of

F48-8

chimney pipe, as shown onTable 2,a fireplace and chimney cap. Ifyou were installing a

TH42 fireplace,

you

would

only

need

the

pipe required for a 22 ft. 6 inch installation

because

TH42 is 6

inches

taller

than

a

TH36 orTH28soyou

is 39 in. Therefore, to determine what otherchimney
