VERTICAL TERMINATION THROUGH A MASONRY CHIMNEY

When using a masonry chimney as a passageway for CoxDENS

PPs, the chase must be structurally sound and free of any debris

or obstructions;

• If only supported with a base support at the bottom

and a standard chimney cover at the top, the maximum

continuous vertical vent length for a rigid CoxDENS

PPs

vent system cannot exceed 164” (50m);

• Multiple CoxDENS

PPs vent or air intake systems can be

installed into one chase;

• Afﬁ x Spacers onto each vent or air intake (offset them),

then pull or lower them individually or bundled into the

Chase;

• CoxDENS

PPs expand slightly during normal operation.

CoxDENS

PPs pipe can expand upwards through the

Chimney Cover;

• Install a Base Support bracket just below the entry point

into the chase;

• Measuring from the base support, attach spacers at

intervals of 78” (2m) or less to the rigid pipe.

NOTE: Spacers serve to keep CoxDENS

PPs away from

rough surfaces and to avoid damage to the pipe during

installation or normal operation. They do not have a support

function. Attach Spacers to the pipe even if the chase is

larger than the reach of the Spacers.
