Installing The Interior Stack; Installing The Barometric Damper - Saturn 125 Operator's Manual

Installing the Interior Stack

WARNING: Single wall stack components may be used only for those portions of the stack
which are located inside your building and away from any fire/burn hazards.
1. Install the single wall stack with proper clearances from combustibles. Also ensure that the stack
is located a safe distance from all shop personnel.
2. Install an elbow at the junction of the horizontal and vertical stack components to allow for easy cleaning
of the stack.
ATTENTION: Avoid additional 90-degree turns in the stack. Each additional 90-degree turn
slows down stack gases, creates back-pressure, and results in repeated burner shutdown and
unnecessary service calls. All other turns in the stack should be at a 45-degree (or smaller) angle.
NOTE: IMPORTANT for Canadian Installations - Local codes may require the installation of
a clean-out tee.

Installing the Barometric Damper

1. Refer to Figure 4L. Install a single wall tee (min. 24 gauge) after the 90 degree elbow in the straight
vertical stack section within three to five feet of the furnace breach. For horizontal stack runs (as shown
in Figure 4M), install the tee after the first straight section of pipe.
NOTE: The tee is required to support the barometric damper. You must purchase this tee when
you purchase your stack materials (6" single wall tee - CB #70301).
2. Refer to Figure 4N. Install the barometric damper in the opening of the tee. Use a small spirit level to
make sure that it is properly level.
3. Install two self-tapping screws as shown in Figure 4N (i.e. one on each side of the barometric damper)
to hold the damper in place. DO NOT install a screw at the bottom of the barometric damper, or the
flapper of the damper will not operate correctly.
NOTE: Specifications for adjusting the barometric damper for proper draft over fire are provided in
Section 8 of this manual.
