Operation and maintenance manual for the Q-PER series boilers with feeders. The producer reserves the right to introduce technical modifications.
2. TECHNICAL DESCRIPTION
2.1. Intended use
Steel heating boilers Q-PER are intended for installation in the
central heating water systems in single-family houses, garag-
es, maintenance rooms etc. These boilers belong to a group of
low-temperature boilers and are not subject to registration in
the regional O
ffi
ce of Technical Inspection. They are intended for
operation in water distribution piping of the gravity hot-water
systems or in open systems with forced circulation, which are
equipped with protections in compliance with the requirements
PN-91/B-02413 applying to the protections of the open water
heating system (considering the Regulation of the Minister of
Infrastructure, Journal of Laws of 2009 no. 5 item 461).
2.2. Transport and storage
Central heating boiler type Q-Per with feeding unit the fuel is
delivered in assembled condition. All the set is foiled and placed
on a transport pallet. The boiler should only be stored indoors
roofed..
2.3. Design description
2.3.1. Water unit
Q-Per series heating boilers are made of P265GH grade steel
sheet, suitable for construction of pressurised equipment, oper-
ating at higher temperatures.Heat exchanger panels are welded,
while the unit casing is reinforced with brackets. Location of
convection ducts allows cleaning using the upper door. Ash and
soot are removed through the bottom door.
2.3.2. Doors
The boiler is equipped with upper door (in models with higher
capacity, also middle door) used for cleaning and bottom door
used for ignition and removal of ash produced in the combustion
process.
2.3.3. Water jacket
The water jacket is a space
fi
lled with heating medium - water.
The structure is made of steel sheet P265GH for pressure equip-
ment intended for operation at elevated temperature.
2.3.4. Boiler casing
Casing panels are
fi
xed to the boiler footing. The casing protects
mechanical components and has a decorative function. The
panels are made of aesthetic powder-coated modules with high
anti-corrosive resistance.
2.3.5. Electronic controller
The microprocessor controller installed in the upper part of the
boiler allows programming the working temperature of the
boiler. The controller is additionally equipped with the operation
control and emergency shutdown sensor, switching the system
o
ff
when water temperature exceeds 95°C. See details in the
“Microprocessor temperature controller operation manual” at-
tached to the boiler documentation.
2.3.6. Fuel feeding system
Takes fuel from the hopper and ensures automatic feeding of the
burner section, using a steel screw conveyor.
