INSTANTANEOUS WATER HEATER
An instantaneous water heater is designed to deliver hot water without the use of a storage tank. It is suitable for applications with variable
load such as restaurants, condominiums, apartments and motels and typically used in conjunction with tempering valves to achieve
temperature control. In some applications it may be appropriate to provide a flow through tank to act as a buffer. Consult factory for
recommendations. (See Figure 19)

WATER HEATER THERMOSTAT SETTING
1. This appliance is provided with an electronic temperature controller as detailed in Section 6.
2. The maximum setting for this water heater is 140°F.
3. There is a hot water scald potential if the temperature controller is set too high.
4.9
WATER FLOW SWITCH (shipped loose)
A water
Flow Switch
is to be installed in the outlet piping on all heating boilers and hot water supply boilers. The
Flow Switch
is wired in
series with the 24VAC safety control circuit.
