2.3The appliance's heating cycle
In this appliance, the cold water enters the bottom of the tank through the cold water inlet (14). The heat of combustion is conducted to the water by the combustion chamber (8) and heat exchanger (11). 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 required for combustion flows via the gas control (16) into the manifold. Orifices are mounted in the manifold. The gas is injected into the burner bars at pressure from these orifices (36). The burner bars together form the burner tray. The injection of gas into the burner bars also draws in the primary air required for combustion. The narrow opening in the orifice causes the gas flow to accelerate. This in turn causes a partial vacuum. It is this partial vacuum that draws in the air (the Venturi effect). Additional air is drawn in through the opening in the burner tray.
The hot surface igniter (20) ensures ignition of the gas/air mixture.
The flue gases released by this combustion are led through the flue tubes (part of 11). Flue baffles (part of 11) are mounted in the flue tubes. These retard the flow of the flue gases, thereby increasing the thermal efficiency of the appliance.
The flue gases are vented from the appliance via the draught diverter (33).
A radiation shield/condensation tray (35) is mounted below the burner tray. This prevents overheating of the floor area below the appliance, as well as serving as a collection tray for condensation water.
The insulation layer (24) prevents heat loss. The inside of the tank is enamelled to protect against corrosion. The anodes (9) offer extra protection.
The entire appliance is controlled by the burner control (40) and the control thermostat (41) or frost thermostat (44). The control thermostat and frost thermostat both independently measure the water temperature (Twater). The
appliance's heating cycle is activated as soon as Twater falls below the threshold value (Tset). The value of Tset depends on the selected mode of the appliance (8.2 "Operating modes"). When the appliance is in OFF mode (frost
protection), this value is determined by the frost thermostat (threshold value = 20°C). When the appliance is in ’ON mode’, the threshold value can be set via the control thermostat (±40°C - ±70°C).
As soon as Twater falls below Tset, the relevant thermostat (control or frost) will close, and the burner control will register demand. The gas control (16) is
opened, and the gas is mixed with air. This mixture is ignited by the hot surface
igniter (20) and the water is heated. As soon as Twater gets higher than Tset, the thermostat opens again. The demand will cease, and the burner control will stop
the heating cycle.
The thermostats have a certain margin both when closing and opening. We refer to this margin as the hysteresis. The hysteresis cannot be adjusted.
2.4Protection for the appliance
2.4.1Introduction
The burner control monitors the water temperature by means of thermostats and ensures safe combustion. This takes place using:
•the Water temperature protection;
•the Flue gas backflow safeguard;
•the Flame probe.
12 |
Instruction manual ADM |
gis
2.4.2Water temperature protection
By means of the frost, high-limit and safety thermostats, the burner control monitors three temperatures that are important for safety. The table explains the working principle of the thermostats with sensors.
Temperature protection
Protection |
Description |
|
|
Frost thermostat |
When the frost thermostat sensor (46) measures a temperature of 20°C or |
|
less, the heating cycle (2.3 "The appliance's heating cycle") will start. |
|
|
High-limit thermostat |
When the high-limit thermostat sensor (39) measures a temperature higher |
|
than 84°C, the high-limit thermostat will open. The heat demand is terminated |
|
and the burner control halts the heating cycle until the high-limit thermostats |
|
close once more. At that moment the burner control will reset the appliance and |
|
the heating cycle will restart. The high-limit safeguard serves to prevent |
|
overheating and/or excessive formation of scale in the appliance. |
|
|
Safety thermostat |
When the safety thermostat sensor (38) measures a temperature higher than |
|
93°C, the safety thermostat will open. The heat demand is terminated and the |
|
burner control will immediately halt the heating cycle. The burner control will go |
|
into a lockout error state. This must be manually reset before the appliance can |
|
resume operation. |
2.5Safety of the installation
2.4.3Flue gas backflow safeguard
The flue gases are discharged to the outside via the draught diverter (33) and the flue (22). To prevent the flue gases from flowing back into the boiler room, the discharge ducting is monitored by a feature called the Thermal Reflux Safeguard (TRS). This uses a flue gas thermostat (37) with a flue gas thermostat sensor (34) that are located in the draught diverter. Under normal circumstances this sensor will register the ambient temperature.
However, if the chimney is not drawing sufficiently (for example, due to a blockage in the chimney), the flue gases will 'reflux' and flow back past the flue gas thermostat sensor. The sensor will then detect an excessive temperature and the flue gas thermostat will open. The demand will cease, and the burner control will immediately stop the heating cycle. The flue gas thermostat will also lock out. It must be manually reset before the appliance can resume operation .
2.4.4Flame probe
To ensure that no gas can flow when there is no combustion, the water heater is fitted with a flame probe (21). The burner control uses the ionisation-detecting properties of this probe for flame detection. The burner control closes the gas valve the instant it determines that there is a gas flow but no flame is present.
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.
The use of an expansion vessel, expansion valve and/or pressure reducing valve depends on the type of installation: unvented or vented.
2.5.1Inlet combination and pressure-reducing valve
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.
The use of an expansion vessel, expansion valve and/or pressure reducing valve depends on the type of installation: unvented or vented.

2.5.2Unvented 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 nonreturn 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").
2.5.3Vented installation
With vented installation, excess pressure is taken up by the open cold water head tank. The head height of the 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 (3.6.3 "Hot water side"), which opens into the cold water tank.
2.5.4T&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 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
valve (3.7.3 "Hot water side").

|
Warning
The installation should be carried out by an authorised installation engineer, in compliance with general and local regulations (1.3 "Regulations").
3.6.1Cold water side
See (A) in the installation diagram (3.5 "Installation diagram").
1.Fit an approved stop valve (4) on the cold water side between the cold water head tank (18) and the appliance, as required by
regulations (1.3 "Regulations").
3.6.2Recirculation pipe
You can install a top to bottom circulation pump to prevent water stacking in the boiler.
1.Optional: depending on the draw-off pattern, fit a recirculation pipe (Ø 22 mm), a stop valve (11) and a top to bottom circulation pump (7).
2.Fit a non-return valve (5).
3.Fit a stop valve (11).
3.6.3Hot water side
See (B) in the installation diagram (3.5 "Installation diagram").
Note
Insulating long hot water pipes prevents unnecessary energy loss.
1.Fit the T&P valve (3).
2.Optional: fit a temperature gauge (12) so you can check the temperature of the tap water.
3.Fit a stop valve (4) in the hot water outlet pipe, for use when servicing.
4.If a circulation pipe is required, continue further by installing the circulation pipe (3.6.5 "Circulation pipe").
3.6.4Drain valve
1.Fit the standard drain valve (9) supplied with the appliance.
2.If applicable, fit a circulation pipe (3.6.5 "Circulation pipe").
If not, fit the blind threaded plug and gasket (C) supplied with the drain valve, as shown in the figure.

3.6.5Circulation pipe
See (C) in the installation diagram (3.5 "Installation diagram").
If an immediate flow of hot water is required at draw-off points, a circulation pump can be installed. This improves comfort and reduces water wastage.
1.Fit a circulation pump (6) of the correct capacity for the length and resistance of the circulation system.
2.Fit a non-return valve (5) behind the circulation pump to guarantee the direction of circulation.
3.Fit two stop valves for service purposes (4).
4.Connect the circulation pipe to the T-piece at the drain valve (9) as shown in the drain valve figure (3.6.4 "Drain valve").

Warning |
Unvented |
The installation should be carried out by an authorised installation engineer, |
|
in compliance with general and local regulations (1.3 "Regulations"). |
3.7.1Cold water side
See (A) in the installation diagram (3.5 "Installation diagram").
1.Fit an approved stop valve (4) on the cold water side as required by applicable regulations (1.3 "Regulations").
2.The maximum working pressure of the appliance is 8 bar. Because the pressure in the water pipe at times can exceed 8 bar, you must fit an approved pressure-reducing valve (1).
3.Fit a non-return valve (5) and an expansion vessel (16).
4.Fit an expansion valve (15) and connect the overflow side to an open wastewater pipe.
3.7.2Recirculation pipe
You can install a top to bottom circulation pump to prevent water stacking in the boiler.
1.Optional: depending on the draw-off pattern, fit a recirculation pipe (Ø 22 mm), a stop valve (11) and a top to bottom circulation pump (7).
2.Fit a non-return valve (5).
3.Fit a stop valve (11).
3.7.3Hot water side
See (B) in the installation diagram (3.5 "Installation diagram").
Note
Insulating long hot water pipes will prevent unnecessary energy loss.
1.Optional: fit a temperature gauge (12) so you can check the temperature of the tap water.
2.Fit the T&P valve (3).
3.Fit a stop valve (11) in the hot water outlet pipe for servicing.
3.7.4Drain valve
1.Fit the standard drain valve (9) supplied with the appliance.
2.If applicable, fit a circulation pipe (3.6.5 "Circulation pipe").
If not, fit the blind threaded plug and gasket (C) supplied with the drain valve, as shown in the figure.
