CHIMNEY INSTALLATION

1. Position the anchor plate/damper with chimney starter collar over the

opening on the top section of the firebox, centering over the opening.

Trace the outer edge of the anchor plate. Using a ¼" masonry drill, drill

into the firebox top through the four holes in the plate. Apply bed of

refractory mortar between the anchor plate and top of firebox. Secure the

plate with the four lag bolts ¼" dia. x 1-1'2" long.

Next install the chimney starter. Set the chimney starter over the damper.

Follow the instructions below for installation of the chimney system, then

secure the starter to the anchor plate with self-drilling screws.

Each double wall chimney section consists of an outer pipe, flue pipe

and one wire spacer. The pipe sections are not pre-assembled and must

be assembled piece by piece as the chimney is installed. When starting

the chimney directly on the fireplace, the flue pipe section must be

installed first with the hemmed end down. The outer pipe section can

then be installed over the flue pipe section with the hemmed end up. See

FIG 6.

WARNING: THE OPENINGS IN THE COLLAR AROUND THE

FIREPLACE MUST NOT BE OBSTRUCTED. NEVER USE BLOWN

INSULATION TO FILL THE DOUBLE WALL CHIMNEY OR THE

CHASE AREA.

2. Place one elbow, without straps, into the damper and slide the inner pipe

to the raised rim. Then place the outer pipe into the starter collar and

secure with screws. Press down on each pipe section until the lances on

the lower end securely engage the knurl on the fireplace starting collar.

The wire spacer will assure the proper spacing between the inner and

outer pipe sections.

3. Attach elbow with the straps to the flue section that will be used to

connect the elbows. Make sure this elbow is connected to the flue

section in the right direction. Attach these two sections to the elbow

on the anchor plate/damper and starter collar. Align the top elbow to the

hole you have already cut into the ceiling, then secure the straps to the

walls to hold the assembly in place.

4. The remaining straight flue sections required to reach the building code

approved height, or a minimum of 18', should be attached one at a time

as they are lowered from the room to the secured elbow on the firebox.

Once the offset section is in position, attach the assembled straight flue

sections to the top elbow, thereby completing all flue connections. Make

sure that both inner and outer pipe sections are locked; when

installing double wall "snap lock" chimneys, it is important to

ensure that the joint between the chimney sections is locked. Check

by pulling chimney upward after locking: the chimney will not pull apart if

it is properly locked. Screws are not necessary to keep the chimney

together. If chimney is 30' or higher, a support section provided by the

chimney manufacturer is required after a straight chimney above the

fireplace run, or above a return elbow after a straight chimney run. The

support is designed to relieve the extra weight load on the fireplace and

elbows when high chimneys are installed. See FIG 8.

Note: For wood burning a minimum of 18' of chimney must be used.

WARNING: DO NOT PACK REQUIRED AIR SPACES WITH INSULATION OR OTHER MATERIAL
