Lorenzetti LZ-1600 N Instruction And Installation Manual

Brand: Lorenzetti

Model: LZ-1600 N

Type: Instruction And Installation Manual

Lorenzetti LZ-1600 N is an instantaneous gas water heater, which means it provides hot water on demand, without the need for a storage tank.

It is powered by natural gas or liquefied petroleum gas and has a flow capacity of 15.5 liters per minute, which is enough to supply hot water for a single bathroom or kitchen.

The heater has three control knobs: one for gas flow, one for water flow, and one for winter/summer mode. The winter/summer mode adjusts the temperature of the water, with the winter mode providing hotter water.

The heater also has a number of safety features, including an ignition sensor, a gas valve, and a relief valve. The ignition sensor ensures that the burner lights automatically when the water is turned on, and the gas valve shuts off the gas supply if the flame goes out. The relief valve releases excess pressure from the water tank if it gets too high.

matically the burner always thefaucet/ tap/valve hotwater is open.

The hot water supply should be made through tap / record specific for this purpose.

Opening the tap, the main burner of the heater turns on and heats the water that runs

throughacoil.

The water gets heat through paassing inside a coil. The lightining control and flame

opresence is madebyan electronic system

5.1 - Using yourequipment

Thewatertemperaturecontrol can be done at three different ways.

Turningit clock wise,you get more gas. Turning it counterclock wise,you get less

gas,consequently, higheror lower temperature of hot water

For comfort and adjusting option, this button allows more precise controlof

hot water temperature . At the winter position is higher heating capacity and at summer

position lower heating capacity. Using this control at the summer position is suitable for

warmerdays

- Turning it counterclockwise, you get increased water supply, turning

clockwise is obtained consequently reduced water supply, higher or lower temperature hot

water.

Youcan control the temperature ( high water flow, means lower temperature or vice versa).

In the case of mixer usage , open tohot water and then gradually open the cold water faucet ,

until reaching the desired water temperature.In order tosave gas, just use the heater with gas

controlbuttonat the intermidiate position or minimum (depending on the weather season).
