Temperature-Pressure
Relief Valve
Explosion
Hazard
Temperature-pressure
relief valve
must comply
with ANSI Z21.22
CSA 4.4 andASME
code.
• Properly sized temperature-relief
valve must be installed in opening
provided.
• Can result
in overheating
and
excessive tank pressure.
• Can cause serious injury 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 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.
Water Damage
Hazard
• Temperature-pressure
relief valve discharge
pipe must terminate
at adequate
drain.
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 inch 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 flow may cause property damage.
The Discharge Pipe:
Shall not be smaller in size than the outlet pipe size of the
valve, or have any reducing couplings or other restrictions.
Shall not be plugged or blocked.
Shall be of material listed for hot water distribution.
Shall be installed so as to allow complete drainage of both the
temperature-pressure
relief valve, and the discharge pipe.
Shall terminate a maximum of six inches above a floor drain or
external to the building.
In cold climates, it is recommended
that the discharge pipe be terminated at an adequate drain
inside the building.
Shall not have any valve between the relief valve and tank.
