Installation shall consist of ___Model TRONIC 6000C WH17
electric tankless water heaters as distributed by Bosch
Thermotechnology Corp. and 97% thermal effi ciency. Supply
voltage shall be 240VAC (208VAC, 220VAC) with a maximum
output of 17.25kW.
Installation shall consist of ___Model TRONIC 6000C WH27
electric tankless water heaters as distributed by Bosch
Thermotechnology Corp. with a thermal effi ciency of 97%. Supply
voltage shall be 240VAC (208VAC, 220VAC) with a maximum
output of 26.85kW.
The tankless water heaters shall be UL listed for the US and UPC
certifi ed.
CONSTRUCTION
Water heater shall be electricity powered with compact tankless
design for whole house operation and an effi ciency rating of 97%.
Primary heat exchanger shall be made from composite material
and the elements shall be made from -sheathed copper. Unit shall
be protected by a tough sheet metal housing. Heat exchanger
shall be rated for maximum working pressure not less than 150
psig. Water heater shall be equipped with a fl ow turbine. Water
connections for inlet and outlet shall be ¾” NPT male.
The controls shall contain an external set point temperature
selector, display screen and a high temperature safety cut-out.
The controls shall not compensate for heat loss, pipe run, and
other factors affecting the outlet temperature at end use. Unit
shall be equipped with a fl ow turbine and a temperature sensor
for constant output temperature. A red light shall indicate
when the unit is powering one or more elements.
INSTALLATION
All aspects of installation of Water Heater shall be in strict
accordance with manufacturer’s instructions. Materials shall
conform to all manufacturer’s recommendations including
electrical connections and wiring.
Water heater piping shall be fi eld constructed of materials
as specifi ed. Water heater shall be installed with individual
isolating shutoff valves for service and maintenance.
MODE OF OPERATION
The heater shall include integral factory wired operating
controls to control all operation and energy input. Control of
discharge water temperature shall be set through an internal
set point with a fi eld adjustment of 95 to 131 degrees F. Heater
shall be capable of maintaining the temperature set point +/- 3
degrees F. This shall be accomplished by switching or pulsing
the power to the electrical elements.
WARRANTY
The heating modules shall carry a 5 year limited warranty.
All other parts and components shall carry a 2 year limited
warranty against defects in materials or workmanship.
