chimney system must be in serviceable condition, and functionally
sound. Before proceeding with following installations, check with
local building jurisdiction to verify this type of installation is allowed
in your area.

in existing masonry chimney. Route the exhaust gases and intake air
through the existing masonry chimney.
7.6.1 Coaxial to Co-Linear Venting Configurations
IMPORTANT: Horizontal vent sections require at least 1/4” (6mm) rise
for every 12” (305mm) of travel.
IMPORTANT: Care should be taken when installing flexible pipe to avoid
a tight bend that may cause abrasion or damage to the flexible pipe.
Vent options listed below (i, ii) allows for a minimum of 0” (0mm) to a
maximum of 24” (610mm) horizontal run using rigid or flexible pipe.
(i)
Minimum / Maximum Vertical Terminations:
Coaxial to Co-linear A 10’ (3.05m) minimum length of 3” x
3” aluminum flexible pipe / 50’ (15.24m) maximum length of 3” x
3” aluminum flexible pipe + termination cap
(ii)
Minimum / Maximum with Rigid Pipe Vertical Terminations:
