Additional instructions

1. Follow instructions in Ultra Boiler Manual to ensure the boiler room provides sufficient

air infiltration.

1. Refer to boiler sequencing control instructions and Ultra Boiler Manual for wiring re-

quirements.

Multiple boilers used with large water volume systems will require water
softening and conditioning. Consult a local water treatment company prior to
installation for analysis and recommendations.

Initial fill water may contain enough minerals to produce damaging deposits.
Additional untreated makeup water will increase scale buildup.

Contamination may also come from scale and rust buildup inside the piping
and heat distribution units of an older boiler system replaced with small multiple
boiler units. The result can lead to loss of efficiency and component failure.

1. Follow proper start-up procedure for flushing any contaminants from the entire system

before initial fill.

2. Hot water systems should not require makeup water after initial fill. Use manual feed

water systems or install a water meter to detect leaks.

3. Repair leaks — constant fill water will cause problems.

4. Refer to Ultra Boiler Manual for more information.
