To avoid water damage or scalding due to relief valve operation:
•
Discharge line must be connected to relief valve outlet and
run to a safe place of disposal. Terminate the discharge line
in a manner that will prevent possibility of severe burns or
property damage should the relief valve discharge.
•
Discharge line must be as short as possible and the same
size as the valve discharge connection throughout its entire
length.
•
Discharge line must pitch downward from the valve and
terminate at least 6” above the floor drain, making discharge
clearly visible.
•
Discharge line shall terminate plain, not threaded, with a
material serviceable for temperatures of 375
o
F or greater.
•
Do not pipe discharge to any location where freezing could
occur.
•
No shutoff valve may be installed between the relief valve
and water heater or in the discharge line. Do not plug or place
any obstruction in the discharge line.
•
Test the operation of the relief valve after filling and
pressurizing the system by lifting the lever. Make sure the
valve discharges freely. If the valve fails to operate correctly,
replace it with a new relief valve.
•
Test relief valve at least once annually to ensure the waterway
is clear. If valve does not operate, turn the water heater “off”
and call a plumber immediately
.
•
Take care whenever operating relief valve to avoid scalding
injury or property damage.
•
For water heaters installed with only a pressure relief valve,
the separate storage vessel must have a temperature and
pressure relief valve installed. This relief valve shall comply
with Relief Valves for Hot Water Supply Systems, ANSI Z21.22
CSA4.4.
FAILURE TO COMPLY WITH THE ABOVE GUIDELINES COULD
RESULT IN FAILURE OF RELIEF VALVE OPERATION, RESULTING
IN POSSIBILITY OF SUBSTANTIAL PROPERTY DAMAGE, SEVERE
PERSONAL INJURY, OR DEATH.
RE-INSPECTION OF RELIEF VALVES: Valves should be inspected
AT LEAST ONCE EVERY THREE YEARS, and replaced if necessary,
by a licensed plumbing contractor or qualified service technician
to ensure that the product has not been affected by corrosive
water conditions and to ensure that the valve and discharge line
have not been altered or tampered with illegally. Certain naturally
occuring conditions may corrode the valve and its components over
time, rendering the valve inoperative. Such conditions can only be
detected if the valve and its components are physically removed
and inspected.
Do not attempt to conduct an inspection on your
own.
Contact your plumbing contractor for a re-inspection to assure
continued safety.
Do not thread a cap or plug into the relief valve or relief valve line
under any circumstances! Explosion and property damage, serious
injury, or death may result.
FAILURE TO RE-INSPECT THE RELIEF VALVE AS DIRECTED COULD
RESULT IN UNSAFE TEMPERATURE AND/OR PRESSURE BUILD-UP
WHICH CAN RESULT IN PROPERTY DAMAGE, SERIOUS PERSONAL
INJURY, OR DEATH.
The water heater must be full of water and the system fully purged
BEFORE powering the water heater. When filling the water heater,
open a hot water tap to release air in the water heater and piping.
All air has been purged from the system when water runs freely
from the faucets.
Applying power to the water heater when it is not full of water will
damage the heat exchanger, and could result in property damage,
serious personal injury, or death. Such damages ARE NOT covered
by water heater warranty.
H. Filling the Heater
• Ensure any drain valves are completely closed.
• Open the shut-off valve in the cold water supply line.
• Open the hot water faucets to allow air to vent from the
heater and piping.
• Allow sufficient time for the heater to completely fill with
water.
Part 5 - Venting
The heater must be vented as detailed in this section. Ensure
the exhaust vent and air intake comply with these instructions
regarding vent system. Inspect the installed appliance thoroughly
to ensure it complies with all applicable code requirements, as
well as the instructions provided in this manual. Failure to properly
install the appliance will result in severe personal injury or death.
