To maintain a 1" clearance to pipe on a roof with

a pitch, a rectangular opening must be cut.

1. Determine the center point through which

pipe will penetrate roof.

2. Determine center point of roof. Pitch is the

distance the roof drops over a given span,

usually 12". A 6/12 pitch means that the

roof drops 6" for each 12" one measure

horizontally down from roof rafters.

3. Use roof opening chart (Figure 23) to

determine correct opening length and

ashing required.

4. Remove shingles around opening mea-

sured. Cut out this section.

5. Add next sections of pipe until end

penetrates roof line. Check to see that

proper clearances are maintained. Extend

chimney by adding sections of double wall

pipe until pipe is minimum of 30" above

highest point of roof cutout. Termination

and chimney must extend a minimum of

36" above highest point where it passes

through the roof.

Determine ashing to be used with roof open-

ing chart. Slide ashing over pipe until base

is at against roof. Replace as many shingles

as needed to cover exposed area and ashing

base. Secure in position by nailing through

shingles (see Figure 24).   

Place storm collar over pipe and slide down

until it is snug against the open edge of the

ashing (see Figures 24 and 25). Apply wa-

terproof caulking to all seams and notches

around storm and also at base around

shingles.

The replace system must be terminated with

the listed round top or chase terminations. In

any case, refer to the installation instructions

supplied with the termination.

Terminations approved for this replace are

RTL-12DM, which can be used for ashing

or chase and STL-12DM for chase style ter-

mination only. Figure 26, page 11, shows an

RTL-12DM round top termination.
