*Flexible Hose
Hot Water Tap
* Flexible Hoses to be procured by the customer, not part of standard product.
** Multi-function Safety Valve comes included with the Water Heater.
• Make necessary plumbing with reference to the Installation Diagram (Fig. 11).
• A. O. Smith recommends Nylon/Stainless Steel (SS) braided hoses (Flexible Hoses) having a
minimum pressure rating of 8 Bar and hoses should be compatible for hot water applications.
• Connect the cold water pipe to the inlet [Blue Cap].
• Connect the hot water pipe to the outlet [Red Cap].
Note: The Multi-function Safety Valve may drip during the usage of the heater. As the water is
heated, it expands and tries to ow back through the inlet pipe, but is prevented by the presence
of the non-return valve. Hence water may drip from the Multi-function Safety Valve. Therefore,
Discharge Outlet is provided to discharge water from the Water Heater. To avoid dripping, it is
recommended to install non-return valve at a distance of at least 40 feet away from the inlet of
the Water Heater.
