Installation and operation manual of the SG(B) buffers

1. Operation and use
1.1. Boiler characteristics
Buffer tanks are used as batteries, which store the heat energy prepared by solid fuel boiler, which is then transmitted in a continuous mode to the heating
system of a central heating and warm usable water.
Buffer tanks are not enamelled, thus they are suitable for storage of neutral medium only (e.g., demineralized boiler water, glycol, etc.). The maximum
allowable operating pressure is 3 bar (0,3 MPa) for buffer tanks and 6 bar (0,6 MPa) for spiral coils.
Buffer tanks complement the following: systems equipped with a heat pump; solar systems; CH boilers.
Buffers can be supplied without thermal insulation or with high quality insulation made of hard polyurethane foam, which reduces heat loss to a minimum.
The tank may have a permanent insulation of hard polyurethane foam or detachable insulation made of soft polyurethane foam.
1.2. Construction description
The main part of the buffer is the tank in which the heating medium is heated. It is made out of a steel sheet and painted with undercoat from the outside.
The buffers have nine 6/4” (internally threaded) hydraulic connections, which makes it possible to connect them in various variants. Three ½" (internally
threaded) connections for the sensor covers are also included, as well as a 1" or 5/4” for type 3000 only (internally threaded) water drain connection at the
bottom of the tank.
1.3. Remember
1. Installation of the buffer tank should be started by reading the installation and operation manual provided with the device. The manual should always
be in the place of use of the buffer tank, as it is often required for inspection by the service.
2. Do not operate the buffer tank without a properly functioning safety valve (applies to closed system).
3. The company is not responsible for safety valve malfunction caused by incorrect installation of the valve and installation errors.
4. Defects discovered during the warranty period should be reported to the manufacturer's service.
5. Vent the heating circuit before the start of the heating season.
6. Periodically check the filling level of the heating system.
7. If the buffer tank is installed in a closed system, an expansion vessel must be installed. If the vessel is already installed, its capacity should be increased
accordingly.
8. It is not allowed to prevent water from dripping from the safety valve – do not clog the safety valve outlet. If the safety valve is leaking water all
the time, the pressure in the water supply installation is too high or the safety valve is defective. The valve outlet should be pointing down. It is
recommended to place a funnel for draining water under the valve. A hose can also be attached to the water outlet for draining leaks caused by opening
of the safety valve. The hose should be resistant to a temperature of +80°C, have an internal diameter of 9 mm and a maximum length of 1.2 m, be
led from the outlet with a downward grade (min. 3%) in an environment where the temperature does not drop below 0°C. The hose should be secured
against reduction in flow capacity (crushing, clogging) and its end should be visible (in order to check the functioning of the valve).
9. Galmet Sp. z o.o. Sp. K. reserves the right to make any modifications and technical changes.
10. The tank has an outer casing made of artificial leather (skay, PVC foil), while the thermal insulation is made of polyurethane or polystyrene foam. It is
not allowed to manipulate open fire directly next to the tank, as it may damage the outer casing as well as the thermal insulation
11. All maintenance and installation works must be performed in accordance with applicable health and safety regulations.
