Eco-Smart ESGH-95-DVLN-2 User manual

High-efficiency condensing tankless gas water heaters
designed for endless hot water.
Outdoor
• Industry Leading! Low Flow Activation – minimum flow
rate of .26 GPM and minimum activation flow rate of .40
GPM ensures the user will receive hot water even in low
demand situations
• Recirculation Pump Kit-Ready – providing faster hot
water at the tap and savings of up to 12,000 gallons
water/year3
• Hot Start Programming – minimizes cold water bursts by
staying in ready-fire state for back-to-back hot water
needs
Performance
1Based on internal testing of 1/2" gas line with gas supply of 7" w.c. up to 24’; Installation conditions vary; Consult the Use and Care Manual, the National Fuel Gas Code (NFPA 54, ANSI Z223.1), and any other
local gas codes when installing an EcoSmart Tankless Water Heater. 2Contact customer service for exact altitude rating for each model. 3Pump kit designed for single unit applications only. 4Savings based on
DOE test procedures.
