5 Flue Information

A. Flue Components

These models are approved to use Simpson Dura-Vent or Hearth & Home Technologies series pipes, components and termination. Approved components are labeled for identifica- tion. This pipe is tested and listed as an approved compo- nent of the stove.

DO NOT USE FIELD-FABRICATED FLUE COMPONENTS.

Refer to the flue manufacturer’s instructions.

This product is approved to be flued either horizontally, through the side wall or vertically through the roof. You may flue through a Class A or masonry chimney if an approved adapter is used.

This gas stove is a balanced flue gas stove. All combus- tion air must come directly from the outside of the building. The flue pipe for this unit consists of an inner and an outer pipe. The inner pipe carries the gas stove exhaust out of the system, and the outer pipe brings fresh combustion air into the gas stove.

•	A round support box/wall thimble or heat shield is
	required when the flueing passes through a combus-
	tible wall.
•	A support box or ceiling firestop is required when the

B. Use of Elbows

CAUTION

ALL flue configuration specifications MUST be followed.

•This product is tested and listed to these specifications.

•Appliance performance will suffer if specifications are not followed.

Diagonal runs have both vertical and horizontal flue aspects when calculating the effects. Use the rise for the vertical aspect and the run for the horizontal aspect. (See Figure

5.1.)

Two 45° elbows may be used in place of one 90° elbow. On 45° runs, one foot of diagonal is equal to 21.6 cm horizon- tal run and 21.6 cm vertical run. A length of straight pipe is allowed between two elbows. (See Figure 5.1.)
