2.2 Installation Types

[CAUTION] Always use insulated ducting with a minimum R-4 insulation factor.

2.2.1 Stand Alone Installation

If necessary, install an in-line heater sized for airflow and design heating temperature to prevent condensation on uninsulated ducts. The heater must have an integrated airflow sensor and over-temperature sensor. Consider the following when deciding if a preheater is required and its placement (before/after supply fan):

• Supply fan minimum operating temperature: 14 °F.
• Minimum distance between preheater and supply fan: 12 inches.
• Distributed air temperature in ducting should not be below 55 °F.

2.2.2 Installation with an AHU

If necessary, install an in-line heater sized for airflow and design heating temperature to ensure air delivered to the AHU is never below the manufacturer's minimum temperature (typically 55 °F). The heater must have integrated sensors. Consider the following for preheater placement:

• Supply fan minimum operating temperature: 14 °F.
• Minimum distance between preheater and supply fan: 12 inches.
• Distributed air temperature in ducting should not be below 55 °F, unless the AHU blower always runs when the supply fan runs (refer to Section 4.2 for wiring).

Connecting the Insulated Ducts to the Unit

1. Slide the 6-in. round flexible duct over the port and secure with a tie-wrap.
2. Pull insulation over the inner ring without compressing it to minimize condensation and heat loss/gain.
3. Use duct tape to seal the outer membrane of the insulated duct to the port's outer ring for an airtight path, reducing heat loss/gain and condensation potential. Avoid blocking test ports with tape.

[CAUTION] Ensure insulation is replaced around any openings in the building envelope to minimize heat loss/gain and condensation.

[WARNING] Ensure the outdoor intake hood is at least 12 inches above ground and 6 feet away from dryer exhaust, furnace vents, central vacuum vents, gas meters, barbecues, combustion sources, garbage bins, or other contamination sources.

Ensure the outdoor intake hood is accessible for annual maintenance. If above the first floor, place it near a window or balcony.

IMPORTANT: Ducting significantly impacts airflow, noise, and energy use. Use the shortest, straightest duct runs possible. Avoid ducts smaller than recommended. Insulation reduces energy loss and inhibits mold growth. Existing ducts may affect rated airflow.
