Tankless water heater (EG and EGH only)

If boiler is used to supply domestic hot water, limit control should be set to supply adequate hot water. Weil-McLain tankless heaters are rated at 200 °F boiler water temperature. To get rated output, set low limit at 200 °F. Limit can be adjusted to meet system hot water

requirements. Differential can be set to 15 ° and adjusted to control level. Lowering the differential will cause a slight variation in water temperature but will decrease burner on-off cycling. High limit should be set at least 20 ° above low limit.
