Systems containing other than Group A1 or B1 refrigerants shall discharge to atmosphere through an approved flaring device.
- Ammonia absorption systems serving a single dwelling unit.
- Where the Authority Having Jurisdiction determines upon review of a rational engineering analysis that fire, health, or environmental hazards will not result from the proposed atmospheric release.
- Lithium bromide absorption system using water as the refrigerant.
Flaring devices shall be designed to incinerate the entire discharge. The products of refrigerant incineration shall not pose health or environmental hazards. Incineration shall be automatic upon initiation of discharge, shall be designed to prevent blow-back, and shall not expose structures or materials to threat of fire. Standby fuel, such as LP-Gas, and standby power shall have the capacity to operate for one and a halftimes the required time for complete incineration of the charge.
Flaring systems shall be tested to demonstrate their safety and effectiveness. A report from an approved agency shall be submitted detailing the emission products from the system as installed.
