1.First hour ratings in Tables 1 and 2 are based on:

•115°F or 140°F domestic outlet water supply temperature from water heater.

•50°F domestic water inlet temperature.

•190°F boiler water temperature leaving Ultra boiler.

•Circulator and pipe sizes as given in the Tables.

2.If the net Btu/hr rating of the boiler is close to the space heating load (for combined systems) — or if there is an unusually large demand for domestic water — increased boiler capacity may be required.
