Key features
- 0.96 UEF condensing efficiency — dual commercial-grade stainless steel heat exchangers extract maximum latent heat from combustion exhaust, cutting natural gas consumption by up to 36% compared to standard tanks.
- Hot Start Programming™ — intelligent pre-warming eliminates cold water bursts during back-to-back household usage.
- High continuous flow capacity — 199,900 BTU/h modulating burner delivers up to 11.0 GPM max flow, sustaining a steady 5.3 GPM continuous output during steep 70 °F (39 °C) winter temperature rises.
- Built-in EcoNet® Wi-Fi — monitor performance, receive proactive maintenance alerts, adjust temperature down to the degree, and track energy usage directly from your smartphone.
- Flexible 2-inch and 3-inch PVC venting — certified for venting runs up to 60 ft with 2-inch pipe or up to 150 ft with 3-inch Schedule 40 PVC, CPVC, or polypropylene.
- Compact space-saving wall mount — lightweight design frees up valuable basement floor space and includes a quick-hang bracket for straightforward installation.
