General Installation Guide Lines
Property damage, personal injury or death can result if these instructions are not followed. They are a guide for professional installers
generally familiar with the installation and maintenance of heating equipment and related vent systems.
s Do not install InnoFlue® where ambient air temperature can exceed 300°F (148°C).
s InnoFlue® can be installed at zero clearance to combustible materials.
s Masonry chimneys or existing B-vents can be used as passage ways for InnoFlue,® provided that no other appliances are or will be
connected.
s Appliances can be fired up immediately after an InnoFlue® vent system is installed and inspected.
s Free standing components (i.e. above the roof) may not exceed a maximum vertical height of 59" (1.5m) without additional
support.
s Unless approved by the appliance manufacturer, only one appliance may be connected to a vent system.
s A Condensate Drain must be installed in the vent system as close to the flue outlet as possible unless the appliance is designed to
manage condensate.
s All penetrations of fire rated walls/ceilings shall be sealed using fire stops that are approved for such use and must be installed
according to this manual and the passive fire stop manufacturers installation instructions.
s When using InnoFlue® Flex, the vent capacity of an appliance must be reduced by 15% when calculating its proper vent diameter
unless otherwise stated by the appliance manufacturer.
s Both rigid and flexible InnoFlue® systems expand and contract slightly during heating cycles and must be installed following these
instructions.
s InnoFlue® can be painted. Use of an adhesion promoter that is specifically recommended for use with polypropylene is allowed.
s Use of Centrotherm supplied supports is strongly recommended. In instances where Centrotherm supports are not suitable, field
supplied supports that are of clam shell design and have a minimum threaded rod diameter of 5/16" (8mm) are permissible.
s InnoFlue® Flex can be sloped a maximum of 45˚ off of vertical, ie minimum of 45˚ off of horizontal.

VERTICAL INSTALLATION (RIGID OR FLEXIBLE,
THROUGH A MASONRY CHIMNEY)
s When using a masonry chimney as a passageway for InnoFlue® Rigid
or Flex, the chase must be structurally sound and free of any debris or
obstructions.
s If only supported with a Base Support at the bottom, the maximum
continuous vertical vent length for a rigid InnoFlue® vent system
cannot exceed 164' (50m).
s 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 flexible InnoFlue® vent system cannot exceed 98’ (30m).
s Multiple InnoFlue® vent or air intake systems can be installed into one
chase.
s Affix Spacers onto each vent or air intake (offset them), then pull or
lower them individually or bundled into the chase.
s To avoid condensate pooling and damage to vent, InnoFlue® Flex
offsets cannot exceed 45˚. Multiple offsets are allowed in a chase.
s Both rigid and Flex expand slightly during normal operation. Rigid pipe
can expand upwards through the Chimney Cover, Flex slightly diverts
from vertical.
s Install a Base Support bracket just below the entry point into the chase.
s When cutting InnoFlue® Flex to length, the rigid section fits into the
female end of any InnoFlue® component (i.e. Base Support for 3” & 4”
diameters).
s When measuring for Flex length from the Base Support, add at least 2'
above the chimney top.
s Measuring from the Base Support, attach Spacers at intervals of 78"
(2m) or less to the rigid or flex pipe.
NOTE: Spacers serve to keep InnoFlue® Rigid or Flex
away from rough surfaces and so 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.

3M™ – RC-1 Restricting Collar: Remove enough RC-1
Restricting Collar to make one wrap around the applied
FS-195+ Wrap Strip with a minimum 1” overlap. Bend the
mounting tabs away from the pipe at right angles, flush
with the bottom floor surface. Warning: Edges of RC-1
Restricting Collar are sharp. Handle with care. Tightly
secure the RC-1 Restricting Collar around the pipe with a
steel hose clamp centered on the RC-1 Restricting Collar
assembly. Two bands of 16 gauge steel tie wire placed
½ from the ends of the RC-1 Restricting Collar assembly
may be used instead of the hose clamp. Secure the collar
to the slab with ¼” x 1 ½” masonry fasteners. Use 1 ¼”
diameter fender washers on the mounting tabs.

BASIC CONCENTRIC INSTALLATION INSTRUCTIONS
Joint connection
s Vent connections must be firmly pressed together so that the
gaskets form an airtight seal.
s To ensure optimum joint connection, secure with two #8 x
1/2” self tapping screws provided. Screw through pre-drilled
holes in metal female socket.
s Secure the vent to the wall or ceiling with pipe clamps or
perforated hanger iron.
Condensation Management
s Horizontal vent lengths must pitch a minimum 5/8”/ft. (3° or
55 mm/m) to the appliance.
Appliance connection (female appliance top)
s Insert the male end of a vent component into the female
appliance top.
Shortening of vent extensions
s The inside pipe should always extend 0.4” (10 mm)
beyond the white outside pipe on the male end of the
vent extension.
s Always cut the male end of the vent pipe extension. Do not
attempt to cut the female end.
s When cutting to size outer vent lengths overlap by
1.25” (37mm).
s Deburr both air intake (outer) and exhaust (inner). Failure to
do so may result in gasket damage.
