Vitocell 100-VH/-BH Installation/Operation/Service
Important Regulatory and Installation Requirements
General information
This water heater/storage unit must be installed in
accordance with local codes. In the absence of local
codes, install this water heater/storage unit in accordance
with the N.E.C. Reference Book (latest edition).
The warranty for this water heater/storage unit is in effect
only when the water heater/storage unit is installed,
adjusted, and operated in accordance with these
Installation and Operating Instructions. The manufacturer
will not be held liable for damage resulting from alteration
and/or failure to comply with these instructions.
This water heater/storage unit may be used independently
when equipped with a heating element or as a storage
unit when used in conjunction with an existing water
heater or boiler.
This water heater/storage unit has been designed and
certified for the purpose of heating potable water. The
installation and use of this water heater/storage unit for
any purpose other than the heating of potable water may
cause damage to the water heater/storage unit and create
a hazardous condition and nullify the warranty.
WARNING
Incorrect operation of this appliance may create a hazard
to life and property and will nullify the warranty.
Do not use this appliance if any part has been submerged
in water. The plumbing professional responsible for the
installation of this water heater/storage unit should be
contacted to inspect the appliance and to replace and part
of the control system, including thermostat (if equipped),
which has been submerged in water.
For water heaters equipped with a heating element; make
sure that the rating plate on the water heater is referenced
for certainty that the correct voltage is being supplied to
the water heater.
WARNING
Do not store or use gasoline or other flammable,
combustible, or corrosive vapors and liquids in the
vicinity of this or any other appliance.
A consumable anode is used to extend tank life. The
removal of this anode, for any reason, will nullify the
warranty. In areas where water is unusually active,
and/or may occur at the hot water faucet due to a
reaction between the consumable anode and impurities
in the water. If this should happen, an alternative anode
may be purchased from the supplier that installed this
water heater/storage unit. This alternative anode will
minimize the odor while protecting the tank. Additionally,
the water heater/storage unit should be flushed with
appropriate dissolvers to eliminate any bacteria.
IMPORTANT
Before proceeding, please inspect the water heater/
storage unit and it's components for possible damage.
DO NOT install any damaged components. If damage
is evident, please contact the supplier where the water
heater/storage unit was purchased or the manufacturer
listed on the rating plate for replacement parts.
Water treatment / filtration
In areas where poor water conditions are suspected
(i.e. lime, iron and other minerals), it is essential that the
water be tested and appropriate action taken to prevent
damage to the indirect heater and ensure the quality
of the water.
Temperature control
The proper temperature setting for domestic hot water
use is 120° F (49° C). If hotter water is required a
tempering device or anti-scald device must be installed
at the domestic hot water outlet of the heater or at the
point of use. Table 1 details the approximate relationship
of water temperature and the time with regard to scald
injury. It is important for the user to understand the
necessity of tempering or anti-scald devices when using
hotter water in domestic water heating systems.
WARNING
Hot water in excess of 120° F (49° C)
can cause scalding!
A tempering valve or anti-scald valve shall be installed
and used according to the manufacture's directions to
prevent scalding. Many state and local codes now require
installation of these devices. The tempering valve or anti-
scald valve will ensure potable water temperatures at the
desired set point with a higher degree of accuracy.
