For Vertical Runs -
One firestop is
REQUIRED
at the
hole in each ceiling through which the flue passes.
To install firestops for vertical runs that pass through
ceilings:
•
Position a plumb bob directly over the center of the
vertical flue component.
•
Mark the ceiling to establish the centerpoint of the
flue.
•
Drill a hole or drive a nail through this center point.
•
Check the floor above for any obstructions, such as
wiring or plumbing runs.
•
Reposition the heater and flue system, if neces-
sary, to accommodate the ceiling joists and/or ob-
structions.
•
Cut a 10" x 10" (254mm X 254mm) hole through the
ceiling, using the firestop pipe opening as a guide.
•
Frame the hole with framing lumber the same size
as the ceiling joists.
4. Install Firestops
For Horizontal Runs -
Firestops are
REQUIRED
on
both sides of a combustible wall through which the flue
passes.
To install firestops (heat shield) for horizontal runs that
pass through either interior or exterior walls:
•
Cut a 10-inch by 12-inch (254 mm X 305 mm) hole
through the wall.
•
Position the firestops on both sides of the hole pre-
viously cut and secure the firestops with nails or
screws.
•
The pipe opening of the firestops
MUST BE
placed
towards the bottom of the firestop.
•
Continue the flue run through the firestop.

WARNING: ENSURE THAT THE HEATER GASKET
SUPPLIED WITH THE HEATER SEALS BETWEEN
THE FIRST FLUE COMPONENT AND THE OUTER
HEATER WRAP.
2. Continue Adding Flue Components
To continue adding flue components in accordance with
the pre-planned flue system configuration, ensure that
each succeeding flue component is securely fitted and
locked into the preceding component in the flue system.
NOTE:
Make sure that seams are
NOT
aligned to prevent
unintentional disconnection.
For elbows that are changing the flue direction, two
screws minimum should be put in the outer flue at the
joint to prevent the elbow from rotating.
3. Install Support Brackets
For Horizontal Runs -
The flue system must be
supported every five (5) feet (1.5m) of horizontal run by
a horizontal pipe support. To install support brackets
for horizontal runs:
• Place the pipe supports around the flue pipe.
• Nail the pipe supports to the framing members.
For Vertical Runs -
The flue system must be supported
every eight feet (2.4 M) above the heater flue outlet by
wall brackets. To install support brackets for vertical runs:
•
Attach wall brackets to the flue pipe and secure the
wall bracket to the framing members with nails or
screws.
