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 top cover 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.

This heater is provided with a properly certified combination 
temperature - pressure relief valve by the manufacturer.

The valve is certifi ed by a nationally recognized testing laboratory that 
maintains periodic inspection of production of listed equipment of materials 
as meeting the requirements for Relief Valves 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 certifi ed 
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.

For safe operation of the water heater, the relief valve must not be removed 
from its designated opening nor plugged.

The temperature-pressure relief valve must be installed directly into the 
fi tting of the water heater designed for the relief valve. Position the valve 
downward and provide tubing so that any discharge will exit only within 6 
inches (15.2 cm) above, or at any distance below the structural fl oor.  Be 
certain that no contact is made with any live electrical part.  The discharge 
opening must not be blocked or reduced in size under any circumstances.  
Excessive length, over 30 feet (9.14 m), or use of more than four elbows 
can cause restriction and reduce the discharge capacity of the valve, see 
Figures 16 or 20.

No valve or other obstruction is to be placed between the relief valve 
and the tank.  Do not connect tubing directly to discharge drain unless a 
6” (15.2 cm) air gap is provided.  To prevent bodily injury, hazard to life, 
or property damage, the relief valve must be allowed to discharge water 
in quantities should circumstances demand.  If the discharge pipe is not 
connected to a drain or other suitable means, the water fl ow may cause 
property damage.
