1. First hour ratings in Tables 3 and 4 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
Gas 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.
