Scope
This kit offers a means to balance the system at the outlets. This kit should only be used when the take-offs are difficult to reach. When possible, balance the system at the take-off (UPC-35-15). Placing the orifice at the take-off allows the sound attenuator duct to remove any noise caused by its restriction.
For small rooms or when only a partial outlet is required, add a balancing orifice. Use balancing orifices sparingly to maximize the airflow.
Installation
Simply plug the appropriate orifice into the opening. These orifices replace the normal winter plug, so a larger winter cap is included. To install the larger cap, turn it over so it covers the lip of the orifice.
