2.Ultra boilers are design-certified for installation on combustible flooring (not carpet).

3.Ultra boilers are tested for 30 P.S.I. working pressure (higher pressure not available).

4.For systems requiring greater than 30 P.S.I. relief valve setting, install a heat exchanger to isolate the boilers from the main system. See page 12 for suggested piping.

5.Maximum operating temperature of each boiler is 190°F.

This manual provides general guidelines for piping and installation. Your installation must comply with all applicable local codes.

When using isolation valves on each boiler, some codes may require providing a low water control and additional limit for each boiler. If desired, consult the codes to determine if exclusion of the individual boiler isolation valves may allow the use of a single water level control and additional limit for the entire multiple boiler system.
