WARNING
Improper installation, adjustment, alteration, service or maintenance can cause
property damage, personal injury, or loss of life. Read and understand the entire
manual before attempting installation, start-up, operation, or service. Installation
and service must be performed only by an experienced, skilled installer or service
agency.
This water heater contains very hot water under high pressure. Do not unscrew
any pipe fittings or attempt to disconnect any components of this water heater
without positively assuring that the water is cool and has no pressure. Always
wear protective clothing and equipment when installing, starting up or servicing
this water heater to prevent scalding injuries. Do not rely on the pressure and
temperature gauges to determine the temperature and pressure of the water
heater. This water heater contains components that become very hot when the
boiler is operating. Do not touch any components unless they are cool.
Failure to follow all instructions in the proper order can cause personal injury
or death. Read all instructions, including all those contained in component
manufacturers’ manuals before installing, starting up, operating, maintaining, or
servicing the water heater.
CAUTION
To reduce the risk of excessive pressures and temperatures in this water heater,
install temperature and pressure protective equipment required by local codes
but no less than a combination temperature relief valve certified by a nationally
recognized testing laboratory that maintains periodic inspection of production of
listed equipment or materials, as meeting the requirements for Relief Valves and
Automatic Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22-latest
edition. This valve must be marked with a maximum set pressure not to exceed
the marked working pressure of the water heater. Install the valve into an opening
provide and marked for this purpose in the water heater, and orient it or provide
tubing so that any discharge from the valve will exit only within 6 inches above, or
at any distance below, the structural floor, and cannot contact any live electrical
part. The discharge opening must not be blocked or reduced in size under any
circumstances.
The heat transfer medium must be water or other non-toxic fluid having a toxicity
rating or class of 1, as listed in clinical Toxicology of Commercial Products, latest
edition.
The pressure of the heat transfer medium must be limited to the maximum of 30
or 75 psig (depending on IBC boiler model) by its approved pressure relief valve.
DANGER
DO NOT store or use gasoline or other flammable vapors or liquids in the vicinity
of this or any other appliance.
If you smell gas vapors, DO NOT try to operate any appliance - DO NOT touch
any electrical switch or use any phone in the building. Immediately, call the gas
supplier from a remote located phone. Follow the gas supplier’s instructions or if
the supplier is unavailable, contact the fire department.
CAUTION
Installation, start-up and
servicing of IBC boilers and
Water Heaters must be done
with due care and attention,
and should only be performed
by competent, qualified,
licensed and trained heating
technicians.
NOTE
The instructions in this
manual focus almost entirely
on installations where the
IBC water heater is used in
conjunction with a compatible
IBC Boiler. It is necessary
for the Installer and Designer
to read the IBC Boiler
manuals and application
notes, to ensure that finished
installations will operate in
harmony and deliver optimal
energy savings and efficiency.
IBC water heaters are
compatible with most other
boiler makes, and can be
an excellent choice, but
Installers and Designers must
tailor their designs to the
specific control, operational
and installation requirements
of any alternate Boiler.
