1.
Put the water heater into ‘Service Mode’. This is done by depressing the small switch located below the communication interface
port.
2.
Turn the set point dial fully clockwise, this should ramp the fan up to its maximum speed.
3.
Adjust screw 2 to give a CO
2
output of 8.8% (± 0.3%). Turning the screw clockwise will reduce the CO
2
level, turning anti-clockwise
will increase the CO
2
level. On the EF150 and EF180, this adjustment should be made to the right hand gas valve only.
4.
Turn the set point dial fully anti-clockwise, this should ramp the fan down to its minimum speed.
5.
Adjust screw 1 to give a CO
2
output of 8.5% (± 0.3%). Turning the screw clockwise will increase the CO
2
level, turning anti-clockwise
will reduce the CO
2
level. On the EF150 and EF180, this adjustment should be made to the right hand gas valve only.
6.
Turn the set point dial fully clockwise and re-check the combustion reading at high fire. Adjust as necessary.
7.
Once the setting has been completed, depress the small switch below the communication interface port to return the water heater
to its normal operating mode.
8.
Record the combustion data and leave with the appliance for future reference.
The dust cap, once reinstalled, should be marked with an anti-tamper indicator.

The temperature selector knob of the operator thermostat will be adjusted to its lowest setting when dispatched from the factory. The operating
thermostat setting should be adjusted to ensure that the water is stored at 60°C and distributed at 50°C within 1 (one) minute at all outlets.
Care is needed to avoid much higher temperatures because of the risk of scalding. At 50°C the risk of scalding is small for most people, but
the risk increases rapidly with higher temperatures and for longer exposure times. The risk to young children and to those with a sensory or
mobility loss will be greater. Where a significant scalding risk has been identified, the use of thermostatic mixing valves on baths and showers
should be considered to reduce temperature, these need to be placed as close to the point of use as possible.
The operating temperature of the water heater can be adjusted using the thumbwheel on the appliance control panel. The LED display on the
panel will change to show the selected set point temperature.

If care has been taken to follow the manufacturer’s instructions there should be no discernible noise from the equipment. The allied pump
motor may have a level of sound that could lead to consideration for acoustic insulation, but care must be taken not to impede ventilation or
airflow to the pump motor

The water heater must be drained if it is to be shut down and exposed to freezing temperatures. Maintenance and service procedures may
also require draining the water heater.
1.
Turn off the water heater electrical disconnect switch.
2.
Connect a hose to the drain valve on the storage vessel.
3.
Locate hose’s discharge in an area where hot water will not cause any damage or injury.
4.
Close the cold water inlet valve to the storage vessel.
5.
Open a nearby hot water outlet to vent the system.
6.
Open the drain valve.
7.
Once the system has been drained, the heat exchanger can be purged of water using an air compressor.
8.
If the water heating system is being drained for an extended shutdown, it is suggested the drain valve be left open during this
period.
