PENETRATING ROOF

To maintain a 1" clearance to pipe on a roof with a pitch, a rectangular

opening must be cut.

1. Determine center point where pipe will penetrate the roof.

2. Determine center point of the 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" measure horizontally down from roof

rafters.

3. Use roof opening chart (Figure 18) to determine correct opening

length and flashing required.

4. Remove shingles around opening measured. 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.

IMPORTANT: If an exposed portion of chimney

is greater than 4' above roofline, use support wires

to keep chimney secured. Support wires may be at-

tached to outer pipe of chimney with screws provided

screws do not penetrate inner flue pipe.

FLASHING INSTALLATION

Determine flashing to be used with roof opening chart. Slide flashing

over pipe until base is flat against roof. Replace as many shingles as

needed to cover exposed area and flashing base. Secure in position

by nailing through shingles (see Figure 19). DO NOT NAIL THROUGH

FLASHING CONE.

Installing Flashing on a Metal Roof

When installing flashing on a metal roof, it is required that putty tape

be used between flashing and roof. Flashing must be secured to roof

using #8 x 3/4" screws and then sealed with roof coating to prevent

leakage through screw holes. A roof coating must also be applied

around perimeter of flashing to provide a proper seal.

STORM COLLAR INSTALLATION

Place storm collar over pipe and slide down until it is snug against

open edge of flashing (see Figure 20). Use SC1 for all round termina-

tions. Apply waterproof caulk around perimeter of collar to provide

a proper seal.

TERMINATIONS

Standard Installation

The fireplace system must be terminated with the listed round top

or chase terminations. Terminations approved for this fireplace are

RTL-8DM, which can be used for flashing or chase and ETL-8DM for

chase style termination only. Figure 21, page 12 shows an RTL-8DM

round top termination.

Follow installation instructions provided with termination being used.
