SIZING ZONE DAMPERS

If the ductwork already exists, simply size the damper to fit the ductwork. For new systems or retrofit jobs:

A. Determine CFM from heat gain or loss calculations.

B. Select damper size using either the round capacities chart, the rectangular capacities chart or by

using a duct sizing table or calculator.

C. Select a Zonex Systems damper to fit the duct size selected for that zone.

Make sure your zone dampers match the type specified in the table showing Maximum Differential Pressure.

INSTALLATION NOTES

1. Do not exceed 700 FPM in a register/diffuser branch duct.

2. If a damper is installed within 3 feet of a register/diffuser, install sound attenuating flex duct between

damper and outlet.

3. Zone dampers should be preceded by 2’

−

4’ of straight pipe where possible.

4. In attic installations and high humidity areas, the Zonex Systems damper should be insulated along with

the ductwork. The hat section on the round damper is delivered with insulation between the hat section

and pipe. Therefore, insulation should be applied to the round pipe and be butted against the hat section

(do not insulate the motor). The motor generates enough heat so that no condensation will develop on it.

5. Remember to allow a 16” gap in the duct for heavy duty rectangular dampers.

6. Medium pressure rectangular dampers slide into a 3¼” wide cutout in the side of the preexisting

ductwork.

7. Minimum open and close positioning is field adjustable on the actuator. The damper is shipped from the

factory to close 100%.

NOTE: Dampers should not be installed with motor upside down in the 6:00 position.

SIZING ZONE DAMPERS

When slaving more than three zone dampers, use the following diagram. An additional 24-volt transformer and control relays are

needed for these applications. Note: All slave dampers need to be model STMPD / STCD

SLAVING MORE THAN THREE ZONE DAMPERS

SLAVING UP TO THREE ZONE DAMPERS

ZONE DAMPER 1

STMPD or STCD damper

ZONE DAMPER 3

STMPD or STCD damper

Up to three dampers can be directly controlled by one zone thermstat. To wire two or

three dampers for a zone, use the following wiring diagram. Remember to size the power

transformer for the total number of zone dampers in the system, 2va per damper.
