CHIMNEY INSTALLATION

This installation will outline a typical chimney installation using 12" double wall air-cooled chimney. For specific

installation instructions for class "A" chimney, refer to the chimney manufacturers installation manual.

WARNING: Do not install chimney smaller than the required minimum. See page 6 for chimney size requirements.

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 sec-

tion with the hemmed end up. See FIG 6.

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

down to the raised rim. Press down on each pipe section until the lances

on the lower end securely engage the knurl on the fireplace. Secure the

damper to the inner pipe by using supplied self-drilling screws. Then place

the outer pipe into the starter collar and secure with screws. The wire

spacer will assure the proper spacing between the inner and outer pipe

WARNING: THE OPENINGS IN THE COLLAR AROUND THE FIREPLACE MUST NOT

BE OBSTRUCTED. NEVER USE BLOWN INSULATION TO FILL THE CHIMNEY

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

used to connect the elbows. Make sure this elbow is con-

nected 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. These sup-

port straps will need to fully support all vertically installed

chimney.

To achieve desired offset you may install combinations of

12", 18", 24", 36", and 48" lengths in-between elbows.

3. The remaining straight flue sections required to reach the

building code approved height should be attached one at a

time as they are lowered from above and secured to the

elbow on the firebox. Once the whole flue is in position,

attach the assembled straight flue sections to the top el-

bow, 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 up-

ward 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 chim-

neys are installed. See FIG 7.

NOTE: All pipe joints between offset elbows shall be secured with two screws ONLY through the outside

pipe. DO NOT penetrate the inner pipe.
