EZ Plate™ Storage Water Heater

9. Do not use the water heater or attached piping as an electrical ground of any kind.
10. After plumbing, confirm all connections, components and fittings are leak free.
11. After checking for leaks, the heat exchanger and all boiler water and hot potable water piping must be
insulated to the minimum pipe insulation thickness specified in ASHRAE 90.1, “Energy Standard for Buildings
Except Low-Rise Residential buildings”.
WARNING: Insulate or guard all surfaces containing hot water. Uninsulated or unguarded surfaces
containing hot water can be hot enough to cause severe burns instantly, if contacted. Failure to insulate or
guard all surfaces containing hot water can result in property damage, personal injury, or death.
Isoler ou protéger toutes les surfaces contenant de l'eau chaude.
4.5 Heat Exchanger Pressure Relief Valve Piping
The EZ Plate heat exchanger is supplied with a pressure relief valve sized in accordance with the ANSI/ASME Boiler
and Pressure Vessel Code, Section VIII. The relief valve must be threaded directly into the dedicated relief valve
fitting located near the top of the heat exchanger and each relief valve discharge must be separately plumbed to an
appropriate floor drain. The discharge line must not be smaller than the relief valve opening, must allow complete
drainage of the valve and line and it must be positioned in the floor drain, such that water or steam forcefully exiting
the drain line does not openly splash.
The water heater must not be operated without a correctly installed, properly sized and properly operating relief
valve. If a replacement relief valve is required, it must be of the same type, pressure rating, and relieving capacity as
the original relief valve supplied with the water heater.
Do not plug or restrict the relief valve or the relief valve drain line.
It is strongly recommended that the relief valve(s) should be manually operated at least once a year. If water does
not freely flow from the manually operated relief valve or if it does no fully reseat when released, the relief valve must
be replaced with a new relief valve with the same ratings.
WARNING: Do not install a reducing coupling, valve or other restriction between the relief valve discharge
and a suitable floor drain. Such restriction could prevent the valve from fully relieving if the pressure
settings are exceeded, which could result in property damage, personal injury or death.
WARNING: Secure the relief valve piping to a suitable floor drain such that very hot water does not openly
splash during a significant relief valve discharge. If the relief valve pipe is not routed and secured to a
suitable drain, hot water discharge can result in property damage, scalding and personal injury or death.
