Step 1.

Determine the desired location of the gas stove. Check to ensure that wall studs or roof rafters are not in the way when the flue system is being planned. If this is the case, you may want to adjust the location of the gas stove.

WARNING

Fire Hazard.

Exhaust Fume Risk.

Impaired Performance of Appliance.

•Ensure flue components are locked together correctly.

•Pipe may separate if not properly joined.

Step 2.

Balanced flue pipe is designed with a locking connection. To connect the flue system to the gas stove flue outlet, a twist- lock adapter is built into the gas stove at the factory. Wall thickness may vary. Remember to include wall thickness in minimum clearances when figuring flueing lengths for your installation needs.

Note: Female ends of balanced flue pipe/elbows are designed to slide straight onto the male ends of adjacent pipes by orienting the pipe indentations so they match and slide into the entry slots on the male ends, see Figure 5.13. Push the pipe sections completely together, then twist-lock one section clockwise approximately one-quarter turn, until the two sections are fully locked. The female locking lugs may not be visible from the outside. They may be located by examining the inside of the female ends.

WARNING

Fire Risk.

Explosion Risk.

Combustion Fume Risk.

Use flue run supports per installation instructions.

Connect flue sections per installation instructions.

•Maintain all clearances to combustibles.

•Do NOT allow flue to sag below connection point to gas stove.

Improper support may allow flue to sag or separate.

Step 3.

For installations using a round support box/wall thimble (check pipe manufacturer's instructions), mark the wall for a 25.4 cm x 25.4 cm square hole. The center of the square hole should line up with the center line of the horizontal pipe, as shown in Figure 5.12. Cut and frame the hole in the exterior wall where the flue will be terminated. If the wall being penetrated is constructed of noncombustible material, i.e. masonry block or concrete, a 17.8 cm diameter hole is acceptable.

Step 4.

Position the horizontal termination cap in the center of the 25.4cm x 25.4cm square hole and run a bead of non-harden- ing mastic around its outside edges, to make a seal between it and the wall. Attach termination cap to the exterior wall with the four wood screws provided. The arrow on the flue cap should be pointing up.
