T & P Valve and Pipe Insulation (if supplied)
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.
TEMPERATURE-PRESSURE RELIEF VALVE
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
