T&P Valve
HOT
COLD GAS
WARNING:
Do not reverse the hot outlet and cold supply line connections to the MOBIUS
Water Heater. This will result in dangerous operation and void the warranty. Make sure the
hot and cold lines are connected properly. Refer to the FOR YOUR SAFETY section at the
front of this manual.
PRESSURE RELIEF VALVE
This unit does not come with an approved temperature and pressure relief valve, however an
approved temperature and pressure relief valve must be installed on the hot water outlet. A
“Tee” fitting should be used to attach the temperature and pressure relief valve.
The pressure relief valve must meet not exceed the following:
Pressure Relief
150 psi
The discharge capacity must be at least 235,000 Btu/hr. The discharge piping for the
temperature and pressure relief valve must be directed so that if it becomes necessary, no
one will be hurt and nothing will be damaged by the escaping water. Attach the run-off tube to
the temperature and pressure relief valve, and run the end of the tube to within 6" of the floor.
Do not install any reducing couplings, valves, or any other type of restriction in this line. This
run-off tube must be installed to allow free and complete drainage of both the valve and the
run-off tube.
If the temperature and pressure relief valve on the appliance discharges periodically, this may
be due either to thermal expansion in a closed water supply system, or a defective
temperature and pressure relief valve. If the T&P valve is the problem, replace it with a new
one. If not, contact the water supplier or a local plumbing inspector for how to correct this
situation.
The temperature and pressure relief valve must be manually operated once a year to check
for correct operation.
Should overheating occur, or should the gas supply fail to shut off, turn off the manual gas
control valve to the appliance.
