Maintain boiler using schedule below
Tankless water heater
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. Lowering the setting 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.
