Optional Installation Instructions
S o m e c o m p a c t m o d e l s h a v e o p t i o n a l p l u m b i n g connections . On these units, if top connection is preferred over the side connection, use the following instructions as they apply to your connection:
To change Temperature and Pressure (T&P) valve location: Remove 3/4” plug from opening in jacket top . Replace 3/4” plug opening with T&P valve; plug original T&P valve opening with 3/4” plug. be sure to reapply pipe joint compound or teflon tape around the threaded ends of the temperature and pressure (T&P) valve and the 3/4” plug when reinstalling components.
To change Cold Inlet location: Remove 3/4” plug from opening in jacket top. Replace 3/4” plug opening with Cold Inlet nipple; plug original Cold Inlet opening with 3/4” plug. be sure to reapply pipe joint compound or teflon tape around the threaded ends of the cold inlet nipple and the 3/4” plug when reinstalling components.
To change Hot Outlet location: Screw 3/4” NPT galvanized cap (not included, purchase locally) onto Side Hot Outlet and install 3/4” NPT nipple (not included, purchase locally) in the opening identified as HOT/T&P location. be sure to reapply pipe joint compound or teflon tape around the threaded ends of the 3/4” npt nipples when reinstalling components.
T & P Valve and Pipe Insulation
Remove insulation for T & P valve and pipe connections from carton.
Fit pipe insulation over the incoming cold water line and the hot water line. Make sure that the insulation is against the side jacket of the heater.
Fit T & P valve insulation over valve. Make sure that the insulation does not interfere with the lever of the T & P valve.
Secure all insulation using tape.

NOTE: Figure above is used to illustrate installation of T&P and pipe insulation only. As indicated in PRODUCT SPECIFICATION Section. Actual optional Cold & Hot / T&P spud location vary from model to model.
Temperature-Pressure Relief Valve
This heater is provided with a properly certified combination temperature - pressure relief valve by the manufacturer.
The valve is certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment of materials as meeting the requirements for Relief for Hot Water Supply Systems, ANSI Z21.22 • CSA 4.4, and the code requirements of ASME.
If replaced, the valve must meet the requirements of local codes, but not less than a combination temperature and pressure relief valve certified as indicated in the above paragraph.
The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 psi = 1,035 kPa) and a discharge capacity not less than the water heater input rate as shown on the model rating plate. (Electric heaters - watts x 3.412 equal Btu/hr input rate)
Your local jurisdictional authority, while mandating the use of a
Compliance with such local requirements must be satisfied by the installer or end user of the water heater with a locally
