Based on simultaneous showers using 2.0 GPM flow rate pre-mixed with cold water line. Flow rates vary depending on temperature of incoming cold water and water heater set temperature. Refer to 9 zone ground water temperature map for accurate sizing. 2 For indoor application, this is the temperature of outdoor intake air. 3 Manifolds with standard RJ11 communication cables. 4 If anti freeze is on and combustion is on, total W will be 217W (85+132). 5 Recommended 24″ clearance for service.
