Maintain boiler using schedule below

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.
