Please read before proceeding
Failure to adhere to the guidelines on this page can result in
severe personal injury, death or substantial property
damage.
When servicing boiler —
To avoid electric shock, disconnect electrical supply before performing
maintenance.
To avoid severe burns, allow boiler to cool before performing
maintenance.
Boiler operation —
Do not block flow of combustion or ventilation air to boiler.
Should overheating occur or gas supply fail to shut off, do not turn
off or disconnect electrical supply to circulator. Instead, shut off the
gas supply at a location external to the appliance.
Do not use this boiler if any part has been under water. Immediately
call a qualified service technician to inspect the boiler and to replace
any part of the control system and any gas control that has been
under water.
Boiler water —
The Ultra heat exchanger is made of aluminum, and requires that
system pH always be between 7.0 and 8.5 and water chemistry be
checked. Chemical treatment may be necessary. See page 24 for details.
Thoroughly flush the system (without boiler connected) to remove
sediment. The high-efficiency heat exchanger can be damaged by
build-up or corrosion due to sediment.
Do not use petroleum-based cleaning or sealing compounds in boiler
system. Gaskets and seals in the system may be damaged. This can
result in substantial property damage.
Do not use “homemade cures” or “boiler patent medicines.” Serious
damage to boiler, personnel and/or property may result.
Continual fresh make-up water will reduce boiler life. Mineral buildup
in heat exchanger reduces heat transfer, overheats the aluminum
heat exchanger, and causes failure. Addition of oxygen carried in by
make-up water can cause internal corrosion. Leaks in boiler or piping
must be repaired at once to prevent make-up water.
Do not add cold water to hot boiler. Thermal shock can cause heat
exchanger to crack.
Freeze protection fluids —
NEVER use automotive or standard glycol antifreeze, even glycol made
for hydronic systems. Use only freeze-protection fluids recommended in
the Ultra Boiler Freeze Protection Supplement.
Follow all guidelines in the Ultra Boiler Freeze Protection Supplement.
Thoroughly clean and flush any replacement boiler system that has used
glycol before installing the new Ultra boiler.
Installer— Read all instructions, including
this manual, the Ultra Control Supplement
and Ultra Vent Supplement, before
installing. Perform steps in the order given.
