2 Working principle of  
the appliance  
Topics covered in this chapter:  
2.1 Introduction  
The figure shows a cut-away view of the appliance.  
2.2 General working  
principle of the  
appliance  
In this appliance, the cold water enters the bottom of the tank through the cold  
water inlet (14).  
Once the appliance and the storage reservoir are completely filled with water,  
they are both constantly under mains water pressure. When hot water is drawn  
from the appliance, it is immediately replenished with hot water from the storage  
tank, which in turn is replenished with cold water. The water in the storage tank  
is heated by a heat exchanger which is connected to the solar heating system.  
The appliance is equipped with a gas/air premix burner (17). The air is drawn in  
through the fan (18). The gas is supplied via the gas control (16) on the intake  
side of the fan. The gas/air mixture is then blown into the burner. The modulated  
supply of gas and air ensures that the optimum gas/air mixture is always  
achieved.  
A gas-fired heat exchanger (11) in the appliance heats the tap water further if  
necessary. The air required by the latter for combustion is forced into the burner  
(17) by the fan (18).  
The heated tap water leaves the tank through the hot water outlet (2). Once the  
appliance is completely filled with water, it will constantly be under mains water  
pressure. When hot water is drawn from the appliance, it is immediately  
replenished with cold water.  
The gas is fed to the burner via the gas control (16). The modulated supply of  
gas and air ensures that the optimum gas/air mixture is always achieved. The  
special construction of the burner causes the mixture to form a vortex (cyclone  
effect) before it becomes ignited. This vorticity improves the ignition on the hot  
surface igniter (20), as well as ensuring optimum combustion efficiency. The  
special design of the heat exchanger (11) ensures that the flue gases are first  
led downwards via the combustion chamber, then upwards via the heat  
exchanger, and downwards again alongside the water in the tank. The flue  
gases gradually become cooler in the process. Because the cooled flue gases  
flow alongside the cold water lower down in the tank, they start to condense.  
This condensation causes latent heat energy to be transferred to the cooler  
water, thereby increasing the performance of the unit. The condensate yielded  
by this process is discharged via the siphon (23).  
Heat losses are prevented by the insulating layer (24) in both the storage tank  
and the appliance itself. Both are enamel-coated on the inside to protect against  
corrosion. The anodes (9) provide extra protection against corrosion. Both are  
fitted with an inspection and cleaning opening (12) for maintenance purposes.

2.3 The appliance's  
heating cycle  
The net water temperature (T ) in the appliance is used to regulate when both  
net  
the gas burner and the solar heating system are started and stopped. T is the  
net  
curve shown in the figure. The controller uses two measured values to calculate  
this temperature: T (7) and T (13). In addition, temperatures S , S and S  
1

are used by the controller of the solar heating system. S is measured in the  
1
solar collector. S is located between the inlet and outlet of the heat exchanger  
2
of the storage tank. S is measured at the top side of the storage tank.  
3
Depending on whether or not hot water is being drawn off, hot water can be  
o
pumped from the storage tank to the appliance. This happens when S is 5 C  
3
higher than T . Water is then pumped from the appliance to the storage tank,  
net  
causing hot water to flow from the storage tank into the appliance. The pump  
switches off as soon as S equals T

2.4.4 Gas valve  
The electronic controller opens the gas valve so that gas can be supplied to the  
burner. As a safety measure, the gas valve has a double shut-off. The double  
shut-off guarantees complete isolation of the appliance from the gas supply.  
To help ensure smooth ignition, the gas valve opens gradually ('softlite").  
2.4.5 Fan  
The fan (18) provides an optimum air supply when there is a heat demand. As  
a safety feature, the fan ensures that any gases present in the combustion  
chamber are removed, both before and after combustion. We refer to this as  
pre- and post-purge.  
The fan speed is continuously monitored by the electronic controller (4). The  
electronic controller takes control if the speed of rotation varies too much from  
the set value.

2.4.6 Pressure switch  
The pressure switch ensures the discharge of flue gases and the supply of  
incoming air during the pre-purge and normal running of the appliance. The  
default state of the pressure switch is open. When sufficient pressure difference  
is reached, the pressure switch closes. However, in the event of a fault, the  
pressure switch is tripped open, and the heating cycle is interrupted. The table  
shows the trip point per appliance.  
Note  
The trip point of the pressure switch is not adjustable.

< 975 Pa  
SGS 100 > 1145 Pa  
< 1115 Pa  
2.4.7 Flame probe  
To ensure that no gas can flow when there is no combustion, the water heater is  
fitted with a flame probe (21). The electronic controller uses this probe to detect the  
presence of a flame, by means of ionisation detection. The electronic controller  
closes the gas control the instant it detects that there is a gas flow but no flame.  
In addition to the appliance's standard built-in safety monitoring, the appliance  
must also be protected by an expansion vessel, expansion valve, pressure  
reducing valve, non-return valve and a T&P valve.  
2.5 Safety of the  
installation  
The use of an expansion vessel, expansion valve and/or pressure reducing  
valve depends on the type of installation: unvented or vented.  
2.5.1 Unvented installation  
With an unvented installation, an expansion valve valve and expansion vessel  
prevent the buildup of excessive pressure in the tank. This prevents damage  
being caused to the enamelled coating (in the appliance) or to the tank. A non-  
return valve prevents excessive pressure buildup in the water supply system.  
This valve also prevents water from flowing backwards from the tank into the  
cold water supply system. The pressure reducing valve protects the installation  
against an excessively high water supply pressure (> 8 bar). These components  
are fitted to the cold water pipe (3.6 "Water connections, Vented").  
2.5.2 Vented installation  
With a vented installation, excess pressure is taken up by the open cold water  
head tank. The height of the head tank determines the working pressure in the  
water heater, which may not exceed 8 bar. The installation must also be fitted  
with a vent pipe from the hot water pipe, that opens into the cold water tank.  
Ideally, the vent pipe should discharge into a separate tundish/drain or  
otherwise to the open cold water head tank. The water heater should also be  
fitted on the hot water side with a stop valve (3.7.2 "Hot water side").  
2.5.3 T&P valve  
A T&P valve is only mandatory in an unvented installation. However, A.O. Smith  
also recommends the use of a T&P valve in vented installations.  
A T&P (Temperature and Pressure Relief) valve monitors the pressure in the  
tank and the water temperature at the top of the tank. If the pressure in the tank  
becomes excessive (> 10 bar) or the water temperature is too high (> 97°C), the  
valve will open. The hot water can now flow out of the tank. Because the  
Instruction manual SGS  
17  
         
2
Working principle of the appliance  
gis  
appliance is under water supply pressure, cold water will automatically flow into  
the tank. The valve remains open until the unsafe situation has been rectified.  
The appliance is fitted standard with a connecting point for a T&P  
2.5.4 Protection for the solar heating system  
Drain-back tank  
The solar heating system may optionally be equipped with a drain-back tank.  
The tank fills itself with the heating fluid when there is no heat demand. This  
avoids overheating of the solar heating system. The high insulation factor of the  
tank also protects the system from freezing of the fluid. The use of the drain-  
back tank also serves to extend the useful life of the fluid.  
The presence of a drain-back tank is set (12.8.1 "Setting the drain-back tank")  
during the installation. Refer to the solar heating system manual for more  
details.  
Fluid temperature  
The heat exchanger of the solar heating system may be filled with glycol. If the  
temperature of the heating fluid is too high, a signal is sent to the controller of  
the solar collector and the pump of the solar collector is switched off. This signal  
is passed to the controller by temperature sensor S .

1
2.5.5 Safety of the solar heating system  
Expansion vessel  
The solar heating system must be equipped with an expansion vessel (16). An  
expansion vessel serves to limit pressure variations in the system. The  
expansion vessel in the solar heating system can withstand a maximum  
pressure of 6 bar. The supply pressure to the expansion vessel depends on the  
static head of the system.  
Besides the expansion vessel, the system is protected from overpressure by an  
expansion valve ( "Expansion valve").  
Expansion valve  
The solar heating system is equipped with an expansion valve (23). The  
expansion valve monitors the pressure in the solar heating system. If the  
pressure is excessive (> 6 bar), then the valve will open. The hot water can now  
flow out of the installation. The valve remains open until the unsafe situation has  
passed, i.e. until the pressure has fallen back below 6 bar.  
Note  
Because the installation is always under pressure and is not automatically  
filled, the system will again need to be replenished (5 "Filling").
