OUTLET TEMPERATURE COMPENSATION ADJUSTMENT – RHEEMPLUS
The maximum outlet temperature of a RheemPlus water heater may be
adjusted to compensate for temperature losses in the pipe work between the
water heater outlet and sanitary fixtures.
Warning: After adjustment of the temperature limiting valve, the water
temperature MUST NOT exceed 50°C from the first tap in the hot water pipe
work after the water heater used for personal hygiene purposes, such as in a
bathroom or ensuite.
To adjust the maximum outlet temperature:
Ensure the temperature of the water in the water heater is up to the
thermostat setting on the water heater.
The temperature of the water can be measured at the temperature pressure
relief valve drain discharge point. Do not measure this temperature from a
hot tap
 Operate the easing lever on the temperature pressure relief valve and
place the thermometer in the flow of water from the relief valve drain
line.
Remove the upper plastic
casing and insulation
covering the pipe work on the
side of the water heater, by
removing the three (3)
retaining screws, to expose
the temperature limiting valve.
Locate the first hot tap in the
hot water pipe work after the
water heater used for
personal hygiene purposes.
Turn on the hot tap fully to
achieve maximum flow.
