PRESSURE RELIEF VALVE
Caution:
When operating the relief valve make sure that the water heater is not operating and the
burner is not lit. Stay as far away from the valve as possible in order to reduce the
possibility of being burned from the release of steam or hot water from the release valve.
There is no necessity to operate the valve unless the system is be purges or the heater
is being removed for replacement or repair.
WARNING:
If a relief valve discharges periodically, this may be due to thermal expansion in a closed
water supply system. Contact the water supplier or local plumbing inspector on how to
correct this situation. Do not plug the relief valve.
MOUNTING THE TANKLESS WATER HEATER ON THE WALL
ThermElite tankless hot water heaters are designed and certified for wall mounting with
no special wall preparation requirements. Select the location for the heater as desired,
following all applicable local codes. Adhere to all indoor clearances that apply to the
installation. Do not install this appliance on a carpeted wall or above any floor covering
which is combustible, such as carpeting or area rugs. The water heater must be
securely attached to a load-bearing wall. Secure the two hooks provided with the heater
to a wall surface. Hollow wall anchors may be used but it is recommended to use
wooden cross pieces secured to the wall studs. Position the cross pieces at the top and
bottom of the water heater. This will keep the water heater level while giving a more
secure fastening. Place the heater on hooks. See Fig.9 for required mounting
clearances to combustible and non-combustible walls
.
WARNING:
If a water heater is installed in a closed water supply system, such as one having a
backflow preventor in the cold water supply line, means shall be provided to control
thermal expansion. Contact the water supplier or local plumbing inspector on how to
control this situation.
NOTE:
An approved pressure relief valve must be installed in conjunction with
this unit. The pressure relief valve must be installed on the hot water line out of
the unit with no check valves or control valves between the water heater and the
pressure relief valve. Do not plug the pressure relief valve. The pressure relief
valve should be manually actuated once a year to check for proper operation.
