PROCEDURE
FOR
INITIAL
LIGHTING
IF THE UNIT IS TO OPERATE ON LPG REFER TO SECTION 16.0 BEFORE PROCEEDING
1.
Ensure that the gas-inlet appliance isolating valve, provided by the installer, is in the “off” position.
2.
Press the UP button on the user control interface panel for 5 seconds to turn the unit on.
3.
The combustion fan should ramp up to full speed to purge the combustion chamber and then drop back to half rate in order to light.
The spark generator should create a spark, visible through the burner sight glass. As the gas-inlet appliance isolating valve is closed,
the controls should go to a flame failure condition after four ignition attempts (SHW35-245CE– SHW116-410CE) or one ignition attempt
(SHW146-410CE). If the above occurs correctly, open the gas-inlet appliance isolating valve and reset the unit by depressing the
Enter/Reset button on the control panel.
4.
The combustion fan will repeat the pre-purge procedure and attempt to light. Once a flame is established, the LCD display will change
to display the Temperature and Set point.
5.
Allow the system to reach temperature to check operation of the control sensors.
6.
Once the unit has reached temperature and shut down, check that the flame has extinguished.

CHECKS
The Lochinvar EcoShield™ series are supplied with a pre-set gas/air ratio inlet assembly. This must not be
tampered with. Any attempt to adjust the gas valve or venturi will invalidate the warranty.

TEMPERATURE ADJUSTMENT PROCEDURE
With the heater firing, the set point can be adjusted by accessing the User Parameter screen on the user control interface panel. To access the
User Parameter screen press and hold the Enter button for 5 seconds. Next press the Enter once to display code u02. Use the Up and Down
buttons to display the desired set point. Once the desired set point is displayed, the Enter button should be pressed 6 more times to store the
value and return the home screen. The set point 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.
15.6
INSTALLATION NOISE
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.
