7.7 Coaxial to Co-Linear
Chimney Conversion
Before conversion, have the existing installation inspected by a
qualified chimney sweep or professional installer. The existing
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.
Follow DIAG. 6 for allowable venting configurations for installation
in existing masonry chimney. Route the exhaust gases and intake air
through the existing masonry chimney.
7.7.1 Coaxial to Co-Linear Venting Configurations
IMPORTANT: Horizontal vent sections require at least 1/4” (6mm) rise
for every 12” (305mm) of travel.
IMPORTANT: The vent heat shield assembly must be installed when
incorporating minimum horizontal venting off the top of the appliance.
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 option 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:
4” x 6-5/8” r 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:
4” x 6-5/8” r 90° elbow for 4” x 6-5/8” pipe + 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
