4.1 - Operation and intended
use of the appliance
This product is a condensing gas appliance, intended for
the production of domestic hot water for use by people.
Consider the D.H.W. circulation pump performance curves
as detailed in paragraph 4.2 and as illustrated in figure 4.3.
The temperature of the domestic hot water can be adjusted
by following the relevant procedure in chapter 7.5.
This appliance must be connected to a domestic hot
water distribution system which has adequately sized
pipes to convey the correct water volume and all pipes
should be fitted with good quality insulation to optimise
the performance of the water heater.
Before installation of the domestic cold and hot water
services should be flushed thoroughly in order to remove
any residues or impurities which could compromise the
good working order of the appliance.

4.2 - D.H.W. circulation pump
performance curves
The pump curves as shown in figure 4.3 outline the
performances which can be archived. It is the designer’s
responsability to ensure that the available pump head
pressure will achieve the desired results.
