2 Working principle of
the water heater
This chapter covers the following topics:
2.1 Introduction

2.2 General working
principle of the water
heater
The water heater is fitted with a modulating premix burner system with 1:1 gas-
to-air ratio regulation. The air required for combustion is delivered by the fan
(18). The gas is supplied via the gas control valve (16) and the venturi (30) on
the intake side of the fan. The 1:1 gas-to-air ratio always guarantees the most
efficient gas/air mixture.
In this water heater, the cold water enters the bottom of the tank through the cold
water inlet (14). The water is heated by means of a heat exchanger (55)
connected to a solar heating system and a gas-fired heat exchanger (11).
The heated tap water leaves the tank through the hot water outlet (2). Once the
water heater is completely filled with water, it will constantly be under mains
water pressure. As hot water is drawn from the water heater, cold water is
immediately added.
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 condens trap (23).
The insulation layer (24) prevents heat loss. The inside of the tank is enamelled
to protect against corrosion. The anodes (9) provide extra protection against
corrosion.
The water heater has an inspection and cleaning opening (12) for maintenance.

2.4.3 Gas control valve
The controller opens the gas control valve so that gas can be supplied to the
burner. As a safety measure, the gas control valve has two valves. Both valves
shut off the gas supply.
2.4.4 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 controller (4). The controller
takes control if the fan rpm varies too much from the value set.
2.4.5 Pressure switch
The pressure switch only guarantees the supply of air during pre-purging of the
water heater. If the pressure difference during pre-purging is sufficient, the
pressure switch closes. The table (3.4.2 "General and electrical specifications")
shows the trip point for each water heater.
Note
The trip point of the pressure switch is not adjustable.
2.4.6 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 controller uses this probe to detect the
presence of a flame, by means of ionisation detection. The controller closes the
gas control valve the instant it detects that there is a gas flow but no flame.
Excessive pressure in the tank can damage the enamelled layer (in the water
heater) or the tank itself. An inlet combination and pressure-reducing valve
prevents this. The inlet combination acts as a stop valve, non-return valve and
overflow valve. If the water mains pressure is too high (3.4.2 "General and
electrical specifications"), a pressure-reducing valve must be used. Both
components must be fitted in the cold water inlet (3.7 "Vented water
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.
16

gis
2.5.1 Unvented installation
With an unvented installation, an expansion valve and expansion vessel prevent
the buildup of excessive pressure in the tank. This prevents damage being
caused to the enamel coating (in the water heater) or to the tank. A non-return
valve prevents excessive pressure build-up 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 water heater
against excess mains water pressure (3.4.2 "General and electrical
specifications"). These components are installed in the cold water
2.5.2 Vented installation
With a vented installation, excess pressure is taken up by the open cold water
head tank. The level of the cold water head tank determines the maximum
water heater must also be fitted with a vent pipe from the hot water pipe, which
opens into the cold water head tank.
Ideally, the vent pipe should discharge into a separate discharge channel/drain
or otherwise to the open cold water head tank. The water heater should also be
2.5.3 T&P valve
A T&P valve is only mandatory in unvented installations. 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
open. The hot water can now flow out of the tank. Because the water heater 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 water
heater is fitted standard with a connection for a T&P valve (3.6.2 "Hot water
2.6 Protection for the
solar heating system
2.6.1 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 against freezing of the fluid. The use of the drain-
back tank also serves to extend the useful life of the fluid.
The existence of a drain-back tank is set (12.10.1 "Setting the drain-back tank")
during the installation. Refer to the solar heating system manual for more
details.
2.6.2 Fluid temperature
The heat exchanger of the solar heating system is 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 .

system enters error mode. The error is also visible
on the display of the SGE water heater
2.7 Safety of the solar
heating system
2.7.1 Expansion vessel
The solar heating system must be equipped with an expansion vessel. 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 600 kPa (6 bar). The supply pressure to the expansion vessel
depends on the static head of the system.
The system is protected from overpressure by an expansion
2.7.2 Expansion valve
The solar heating system is equipped with an expansion valve. The expansion
valve monitors the pressure in the solar heating system. Should the pressure
become higher than 600 kPa (6 bar), 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 to below 600 kPa (6 bar).
Note
Because a closed system is pressurized and is not filled automatically, the

We recommend unpacking the water heater at or near its intended location.
3.2 Packaging
Caution
The water heater may only be manoeuvred in an upright position. Take care
that the water heater is not damaged after unpacking.
The water heater is suitable for either open or room-sealed combustion. If
installed as a room-sealed water heater, it is independent of the installation
site for the necessary external air supply. In this event, there are no additional
ventilation requirements.
3.3 Ambient conditions
If the water heater is to be installed as an open system, it must meet the
locally-applicable directives and ventilation regulations for open water
heaters.
The possible installation types are B23, C13, C33, C43, C53 and C63.
Caution
The water heater may not be used in rooms where chemical substances are
stored or used due to the risk of explosion, and corrosion of the water heater.
Some propellants, bleaching agents and degreasing agents etc. disperse
vapours that are explosive and/or cause accelerated corrosion. If the water
heater is used in a room in which such substances are present, the warranty will
be void.

1) Parallel systems with diameter of 100 mm. If the maximum total length when
using a diameter of 130 mm is insufficient, a diameter of 150 mm must be
used. Any diameter enlargement must be carried out on both air supply and
flue gas outlet.
You must use the longest pipe when calculating the pipe length. For example, if
the chimney pipe is 4 metres and the air supply pipe is 3 metres, use 4 metres
as the length for the calculation. Next, add the L
for every 90° and 45°
equivalent
bend to this 4 metres, in both the air supply and flue gas outlet. The following
practical example illustrates how to use the table.
Practical example of parallel flue gas discharge
Example
The figure shows a SGE 60 installation. This has to be fitted with a 4 m parallel
pipe 100 mm in diameter, plus four 90-degree bends. The configuration must be
checked for compliance with the requirements stated in the table.

Installation
is
Appliance with parallel flue gas discharge material
The longest pipe must be used to check the maximum length. In this case, the
chimney pipe is the longest. This is 4 metres. This 4 metres is the sum of pipe
sections 1 and 2. The length of the transition piece can be ignored. The total
number of bends used in the chimney flue and air supply , is 4. The bend in the
transition piece can be ignored. According to the table, 4.6 metres must be
added for each bend. This brings the total pipe length to:
(4.6 x 4) + 4 = 18.4 + 4 = 22.4 m.
This is less than the maximum length of 55 metres stated in the table. The
installation therefore meets the requirements.

There are various types of errors, all falling into one of two groups:
-
LOCK OUT ERRORS
When the cause has been removed, these errors require a reset with
the

-
BLOCKING ERRORS
These errors disappear automatically once the cause of the error has
been removed, after which the water heater resumes operation by
itself.

14 Service interval
A service should be carried out at least once a year, both on the water side and
on the gas side. Among other things, the service interval depends on the water
quality, the average burning time per day and the set water temperature.
14.1 Introduction
Note
Regular maintenance extends the service life of the water heater.
To determine the correct service interval, it is recommended to arrange for the
service and maintenance engineer to check the water heater on both the water
and gas side three months after installation. Based on this check, the best
service interval can be determined.
The service interval is a feature of the controller to help the service and
maintenance engineer set the maintenance frequency, based on the number of
months that the appliance has been running.
14.2 Determining service
interval
The service interval can be set to: 6, 9 or 12 months. The default setting is 12
months.
Once the set number of months has elapsed, the message
SERVICE REQUIREDwill appear on the display. When this message
appears, the service and maintenance engineer must be contacted.

Caution
15.1 Introduction
Maintenance may only by carried out by an approved service and
maintenance engineer.
At each service, the water heater undergoes maintenance on both the water
side and the gas side. The maintenance must be carried out in the following
order.
Note
Before ordering spare parts, it is important to write down the installation type,
water heater model, and the full serial number of the water heater. These details
can be found on the rating plate. Only by ordering with this information can you
be sure to receive the correct spare parts.
To test whether all components are still working properly, complete the following
steps:

15.3 Water-side
maintenance
15.3.1 Introduction
The following steps must be carried out on the water side:
15.3.2 Descaling and cleaning the tank
Scale and lime build-up prevent effective conduction of the heat to the water.
Periodic cleaning and descaling prevents build-up of these deposits. This
increases the service life of the water heater, and also improves the heating
process.
100
Instruction manual SGE
Download from Www.Somanuals.com. All Manuals Search And Download.
s
Take the rate of scale formation into account when deciding on the service
interval. Scale formation depends on the local water composition, the water
consumption and the water temperature setting. A water temperature setting of
maximum 60°C is recommended for the prevention of excessive scale build-up.
To guarantee a good, watertight seal around the cleaning opening, replace the
gasket, washers, bolts and, if necessary, the lid with new parts before
reassembly (see the figure). A special set is obtainable from the
supplier/manufacturer.
To simplify descaling and cleaning of the tank, the water heater is equipped with
two cleaning openings.

1. Remove the cover plate (1) on the outer jacket (see the figure).
2. Undo the bolts.
3. Remove the cover and the gasket.
4. Inspect the tank and remove the loose scale deposits and contamination.
5. If the scale cannot be removed by hand, descale the water heater with a
descaling agent. Contact the supplier/manufacturer for advice on what
descaling agent to use.
6. Close the cleaning opening. To avoid damage to the tank, tighten the bolts
that fasten the lid with a torque no greater than 50 Nm. Use suitable tools for
this.
15.3.3 Clean condensation water discharge
To prevent blockages, it is essential to clean the condensation water discharge
and condensation trap regularly.

the glass-lined steel tank of a water heater supplied by A.O.Smith
proves within 3 years of the original installation date to be leaking due to rust or
corrosion occurring on the water side, then A.O.Smith shall offer to replace the
defective water heater with an entirely new water heater of equivalent size and
quality. The warranty period given on the replacement water heater shall be
equal to the remaining warranty period of the original water heater that was
supplied. Notwithstanding that stated earlier in this article, in the event that
unfiltered or softened water is used, or allowed to stand in the water heater, the
warranty shall be reduced to one year from the original installation date.
For warranty and installation and conditions of use, please see the manual
included with the collectors.
16.3 Collector warranty

associated with the replacement shall not be borne by
A.O.Smith.
16.6 Scope of the
warranty
A claim on grounds of the specified warranty must be submitted to the dealer
from whom the water heater was purchased, or to another authorised dealer for
A.O.Smith Water Products Company products. Inspection of the water heater as
referred to in articles 1 and 2 shall take place in one of the laboratories of
A.O.Smith Water Products Company.
16.7 Claims
A.O.Smith grants no other warranty or guarantee over its water heaters nor the
(assemblies or parts of) water heaters supplied for replacement, other than the
warranty expressly set out in this Certificate.
16.8 Obligations of
