pipe section must be installed first with the lanced side up. The outer pipe section can then be installed over the flue pipe section with the hemmed end up. Press down on each pipe section until the lances securely engage the hem on the firebox starter. The wire will assure the proper spacing between the inner and outer pipe sections.

Continue to assemble chimney sections as outlined above, making sure that both the inner and outer pipe sections are locked together (see Figure 13). When installing double wall snap-lock chimney together, it is important to assure the joint between the chimney sections is locked. Check by pulling chimney upward after locking. The chimney will not come apart if properly locked. It is not necessary to add

screws to keep the chimney together.

Chimney Pipe

The DESA Heating, LLC chimney system is a snap-lock, double-wall pipe. It consists of a stainless steel inner flue pipe(s), a galvanized outer pipe and a wire spacer. Each section of pipe comes in lengths of 12", 18", 36" and 48". The actual lineal gain for each is measured after each section is fully connected. Lineal gain is the actual measurable length of a part

after two or more parts are connected.

Pipe Installation

The pipe sections must be assembled independently as the chimney is installed. When connecting chimney directly to the firebox, the inner flue

where the chimney penetrates a floor or ceil-

ing joist space. Their purpose is to establish and maintain the required clearance between the chimney and the combustible materials.

When penetrating a floor or ceiling at an angle, use firestop spacer number V30FS-8DM (see

Replacement and Accessory Parts, page 14). When the pipe passes through a framed open-

ing into a living space above, the firestop must

be placed onto the ceiling from below as shown in Figure 14, page 8. When the pipe passes

through a framed opening into an attic space

above, the firestop must be placed on the attic

floor as shown in Figure 15, page 8.
