When these messages appear and/or the water heater will lock out, it means that there is not enough flow over the water heater. In this case
check the pump is operating correctly.
The water heater has a built in water pressure switch. If water pressure of the system drops under a certain limit, the water heater will go in a
lock-out.
During and after the commissioning of the water heater, the operation of the water heater pump must be checked, before leaving the installation
room.
Always check the pump is running before firing the water heater.

ELECTRICAL INSTALLATION

Notes on the requirements for electrical installation are provided in
shown in EcoForce Wiring Diagram

GAS INSTALLATION

For design see GAS SUPPLY. See 3.0 for details on the position of the gas connection.

WATER CONNECTIONS

For design see WATER CONNECTIONS
The system should be thoroughly flushed out with cold water without any circulating pump in position. Ensure all the valves are
open.
If a return pump is to be fitted, it should be fitted before the system is filled and air locks cleared. Check the system for leaks and repair as
necessary. If the system is configured in an unvented arrangement, check the expansion vessel cushion pressure.

COMMISSIONING THE EQUIPMENT

G C
ENERAL HECKS
A person deemed competent MUST be responsible for the commissioning of this equipment. Before attempting to commission any
equipment, ensure that personnel involved are aware of what action is about to be taken and begin by making the following checks:
1. Flueway passages to chimney are clear.
2. Adequate ventilation exists in the plant room (if necessary)
3. The system is fully charged with water, ready to receive heat. All necessary valves are open and the building return pump (if fitted)
is circulating water.
4. The gas supply pipework is clear of any loose matter, tested for soundness and purged.
5. The condensate drain is installed correctly and the condensate trap is filled with water.

QUIPMENT HECKS
This unit has been designed for a nominal gas inlet pressure of 20 mbar when used on natural gas. Information relating to propane firing can
be found in LPG FUEL
1. Gas supply is connected but turned to the "off" position. Any unions or fittings are correctly tightened, test points are closed and the
ignition electrode lead is connected correctly. Ensure the ceramic sheath around the ignition electrode is not cracked or broken.
2. Ensure electricity supply is connected.
3. Check that the circulating pump is fully bled.
