CHIMNEY PIPE

FMI PRODUCTS, LLC chimney system consists of 12", 18", 24", 36"' and 48" snap-

lock, double-wall pipe segments, planned

for maximum adaptability to individual site

requirements. Actual lengths gained after fit-

ting overlaps must be taken into consideration (lineal gain) and are given in lineal gain chart

(see Figure 6). Lineal gain is the actual mea-

surable length of a part after two or more parts

are connected. For Canada, use chimney parts

designated "HT".

ASSEMBLY AND INSTALLATION OF DOUBLE WALL CHIMNEY SYSTEM

Each double wall chimney section consists of a galvanized outer pipe, a stainless steel inner flue pipe and a wire spacer. Pipe sections must be assembled independently as chimney is installed. When connecting chimney directly to fireplace, inner flue pipe section must be installed first with lanced side up. Outer pipe section can then be installed over flue pipe section with hemmed end up. Press down on each pipe section until lances securely engage hem on fireplace starter. Wire will assure proper spacing between inner and

outer pipe sections.

WARNING: The opening in the collar around the chimney at the top of the fireplace must not be obstructed.Neveruseblowninsulation to fill the chimney enclosure.

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

together (exception, see Figure 9, page 8).
