DESIGN GUIDELINES FOR 6039I INSERT INSTALLATION

INSTALLATION INTO A MASONRY FIREPLACE

When installing into a masonry fireplace, DO NOT

remove any bricks or masonry, with the following

exception: masonry or steel, including the damper

plate, may be removed from the smoke shelf and

adjacent damper frame, if necessary, to accom-

modate a chimney liner. Do this only if their re-

moval will not weaken the structure of the fire-

place or the chimney, and will not reduce protec-

tion for combustibles to less than that required by

national building codes.

Installation must include a chimney liner (3” or 4”

Pell Vent “PL” Piping) that extends the full height

of the chimney and meets type HT requirements.

The liner must be securely attached to the insert

and the chimney top. The chimney must be sealed

either at the top or at the damper area with a

non-combustible plate to prevent room air pas-

sage to chimney cavity.

Outside combustion air may be drawn through the

chimney top or through an existing ash cleanout.

INSTALLATION INTO A FACTORY-BUILT

(METAL) FIREPLACE

When installing into a zero clearance fireplace,

The firebox must accept the insert without modifi-

cation other than removing bolted or screwed to-

gether pieces such as smoke shelf/deflectors, ash

lips, screen or door tracks, and damper assem-

blies. These items must be re-installed if the in-

sert is removed and not replaced. The removal of

any part must not alter the integrity of the listed

fireplace in any way.

The factory built fireplace must be listed per UL

127. Installation must include a chimney liner (3”

or 4” Pell Vent “PL” Piping) that extends the full

height of the chimney and meets type HT require-

ments. The liner must be securely attached to

the insert and the chimney top. The chimney must

be sealed either at the top or at the damper area

with a non-combustible plate to prevent room air

passage to chimney cavity.

For raised hearth installations, adjust the leveling

bolts under the front of the unit.
