Technical Documents
i250 Key Features:
- Masterless Cascading – Eliminate single-point failure with our patented Masterless Cascading technology. If one cascaded unit is offline for servicing, all other units regroup and continue to operate.
- Eliminate Mixing Valves & Lower Legionella Risks – With no storage tanks, there’s a lower risk for Legionella growth. By eliminating the need for mixing valves, this feature also reduces their associated unreliability and costs.
- Plastic Vent Temperature Overshoot Control – Maintains safe stack temperature below the vent’s maximum temperature rating.
- Multiple Venting Configurations – Include concentric, snorkeling, terminations in different pressure zones and single-pipe vent, smart common venting.
- Numerous Levels of Built-in Safety Features – Prevent flue from back drafting, including fan speed control and a mechanical damper.
- Factory Installed Strainer – Units deliver debris-free inlet water to the system.
