Working principle of the water heater
12 Instruction manual CH
2
gis
In this appliance, the cold water enters the bottom of the tank through the cold
water inlet (26). The heat of combustion is conducted to the water by the
combustion chamber (10) and flue tubes (4). The heated tap water leaves the
tank through the hot water outlet (15). 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 appliance has an ignition probe that lights the pilot flame burner (12).
The gas required for combustion flows via the gas control (12) into the manifold.
There are orifices in the manifold. The gas is injected into the burner bars at
pressure from these orifices (29). 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.
When the gas/air mixture starts to flow, it is ignited by the pilot burner.
The flue gases generated by this combustion are led through the flue tubes (4).
Flue baffles (5) are fitted inside the flue tubes. These retard the flow of the flue
gases, thereby increasing the thermal efficiency of the appliance.
The flue gases are exhausted from the appliance via the draught diverter (2).
A radiation shield/condensation tray (11) 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 (6) prevents heat loss. The inside of the tank is enamelled
to protect against corrosion. The anodes (3) offer extra protection.
Instruction manual CH 13
gis
2.3 Water heater
operating cycle
The entire appliance is regulated by a control thermostat. The control
thermostat monitors the water temperature (T
water
). The appliance's heating
cycle is activated as soon as T
water
falls below the specified threshold value
(T
set
). The value for T
set
can be adjusted using the control thermostat (±40°C to
±70°C).
As soon as T
water
drops below T
set
there is a demand, and the control
thermostat closes, causing the main valve on the gas control to open. The gas
mixes with the air it draws along. This mixture is ignited by the pilot burner and
the water is heated. As soon as T
water
exceeds T
set
, demand ceases, the
thermostat opens again, and the heating cycle stops.
The control thermostat has a certain margin both when closing and opening. We
refer to this margin as the hysteresis. The hysteresis cannot be adjusted.
2.4 Protection for the
water heater
The burner control monitors the water temperature by means of thermostats
and ensures safe combustion. This takes place using:
•the Gas control
•the Thermocouple
•the Water temperature protection
•the Flue gas backflow safeguard
2.4.1 Gas control
The gas control has 2 valves for safety purposes:
1. The main valve, which controls the gas supply to the burner tray and which
is switched via the I/0/II switch circuit and the control, high-limit and flue gas
thermostats. This circuit is powered by the supply voltage.
2. The safety valve, which controls the gas supply to the pilot burner and which
is switched via the thermocouple circuit and the safety thermostat. This
circuit is powered by the millivoltage from the thermocouple that is located
in the pilot flame. Whenever the safety valve closes, the main valve also
closes.
2.4.2 Thermocouple
1. To prevent gas flowing when there is no combustion, a thermocouple is
fitted. As a result of the presence of the (permanent) pilot flame, the
thermocouple maintains a millivoltage which keeps the gas control's safety
valve open.
2. If the pilot flame goes out, this voltage disappears and the gas control's
safety valve closes, interrupting the gas supply to the burner tray.
2.4.3 Water temperature protection
To ensure a safe water temperature is not exceeded, the high-limit thermostat
sensor is installed at the top of the appliance. This is because stratification
('stacking') of the water temperature can mean that the temperature at the top
of the appliance can be considerably higher than the set temperature for the hot
water.
In the event that both the control and high-limit thermostats should fail, there is
also a safety thermostat.
The table explains how the high-limit and safety thermostats respond to the
sensors.
Working principle of the water heater
14 Instruction manual CH

Temperature protection
2.4.4 Flue 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 .
2.5 Safety of the
installation
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.
2.5.1 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 (3.7 "Vented water connections").
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 (3.6.3 "Hot water side").
Protection Description
High-limit thermostat If the high-limit thermostat sensor (39) detects a temperature greater than
84°C, the high-limit thermostat will open. The demand will cease, and the
burner control will stop the heating cycle until the high-limit thermostat closes
again. At that moment, the burner control resets the appliance, and the heating
cycle resumes. The high-limit safeguard serves to prevent overheating and/or
excessive formation of scale in the appliance.
Safety thermostat If the safety thermostat sensor (38) detects a temperature greater than 93°C,
the safety thermostat will open. The demand will cease, and the burner control
will immediately stop the heating cycle. A lockout error of the burner control
takes place. It must be manually reset before the appliance can resume
operation .
Instruction manual CH 15
gis
2.5.3 T&P valve
A T&P valve is only mandatory in an unvented installation. However, the supplier
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 (3.6.3 "Hot water side").
