 Part Number 550-110-592/0408
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 00 °F boiler
water temperature. To get rated output, set low limit at
00 °F. Limit can be adjusted to meet system hot water requirements. Differential can be set to 1 ° 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
0 ° above low limit.
