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.

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
