Venting

All horizontal pipe runs must be graded 1/4 inch per

foot upwards in the direction of the exhaust ﬂ ow. The

ﬁ nal pipe length, when terminating through the wall

may be graded downwards slightly to prevent water

migration.

Wall Thickness

The appliance vent is suitable for penetrating a com-

bustible wall up to 14 inches (36 cm) thick.

A non-combustible wall can be any thickness up to the

maximum horizontal run of vent pipe allowed for the

particular installation—see page 21.

Vent Penetration through Walls & Ceilings

Combustible: When penetrating through combustible

walls and ceilings, frame a minimum of 10 inch x 10

inch opening and ensure that the insulation is kept

clear of the vent pipe using either a wall thimble

or an attic insulation shield. Follow the installation

instructions supplied with the individual venting

components.

Non-combustible: If the wall is totally non-combustible

(e.g. masonry block or concrete), mark for a 7 inch

circular hole.

In both cases, the center of the hole should line up with

the center line of the horizontal vent.

Co-Linear Direct Vent Installations for Free

Standing or Recessed Installations (ﬂ exible

piping)

Converts the appliance outlet collars to accept two

3-inch diameter ﬂ exible liners for installation into

existing solid-fuel burning ﬁ replaces and chimneys.

Requires a co-linear adapter at the appliance and

either a co-linear terminal or co-linear-to-co-axial

terminal at the top of the chimney. Sidewall co-linear

installation is also possible using a 720WSK Sidewall

Terminal Kit—see instructions packaged with the

720SWK. A list of approved venting accessories is

shown on pages 41–42 of this manual.
