NOTE: Your water heater is insulated to minimize heat loss
from the tank. Further reduction in heat Boss can be
accomplished by insu[ating the hot water lines from the
water heater.

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 top
cover of the heater.
Explosion Hazard
, Temperature-pressure relief valve
must comply with ANSI A21.22
and ASME code.
" Properly sized temperature-relief
valve must be installed in opening
provided.
, Can result in overheating and
excessive tank pressure
" Can cause serious iniury or death.
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 Valves and Automatic Gas Shut-off Devices 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.
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 fitting of the water heater designed for the relief valve.
