Prity PMV TV Fireplace Instruction Manual
TECHNICAL DESCRIPTION
The fireplaces and fireboxes to build-in of the company Prity 95 Ltd. are intended for heating of domestic premises using solid fuel — dry wood.
The variety of models permits the formation of the desired interior, coziness, convenience and thermal comfort.
For cooking needs, the technologies in an oven and on a plate can be uses, and the models with a water heat exchanger can transfer heat to adjacent rooms or to a boiler.
The main component of the combustion is the air sucked by the natural gravitational draught, which is controlled by means of the primary air nozzles.
In the cases when the nozzles and flue outlet flap are left open, intensive combustion is achieved with thermal power indicated in the table and in the package of the device.
INSTALLATION INSTRUCTIONS
The fireplace is placed on a stable horizontal fireproof floor. To protect the floor, a stable and fireproof pad can be used, which protrudes at least 50 cm in front and 30 cm from the side.
In the radiating area of the stove, at a distance of 40 cm around it, and at least lm in front of the glass there shall be no flammable or easily flammable objects and partitions damaging by the radiated heat.
Before connecting the fireplace to the chimney, consult a specialist, who shall give you a written guarantee for its functional safety.
Attention : The shared responsibility towards third parties for the serviceability and the safety of the chimney can be joint and unlimited. The connecting elements (rosette and stove-pipes) must be fixed tightly and firmly, so as they may not enter the passage section of the chimney.
The pipes must be the same size as connecting pipe of the cooker.
It is not allowed to change the cross-section of the flue, different from the manufacturer! It is recommended that the fireplace works with a separate chimney. If other heating appliances are connected in the same chimney, it must be pre-designed for that.
The fireplace must receive fresh air at least 4 m3/h for each kilowatt from its heat output. When necessary, inflow from adjacent premises or outside air must be provided.
The combustion process of the fireplace must not feel shortage of air on the action of gravity or forced aspirations, because it is a prerequisite for incomplete combustion or return of exhaust gases to the premises.

General rules and recommendations when using a Fireplace with water heat exchanger.
-
Before the construction of the installation it is recommended that the heat losses be calculated by a specialist for the concrete case.
-
We recommend that the stove be connected to an open heating system, but when connected to a closed system, it must be protected by a safety hydraulic valve set at 1,5 bar.
-
To ensure deaeration of each branch and element of the installation at any time of its operation.
-
All elements of the installation must be ensured against freezing, especially if the expansion vessel or other parts of it are located in unheated premises. If it is impossible to ensure non-freezing of any part of the installation, propylene glycol has to be used instead of coolant water.
CAUTION: Freezing of some of the water in a heating system can cause an explosion with irreparable damage. -
In the installations with forced circulation, a backup power supply (UPS) should be provided – a battery with a 12V / 220V (50Hz) converter to guarantee uninterrupted mode of the pump in case of emergency shutdown of the power supply. It is recommended to switch the circulation pump on and off with a thermostat duplicated with a manual electric switch / see diagram 11-3 /.
-
The first service cleaning of the pump filter must be performed immediately after testing the installation.
-
If an old installation is used, it must be repeatedly washed (sluices) of the accumulated contaminants that would be deposited on the surfaces of the water jacket.
-
Do not use coal with high sulfur content and do not get them wet.
-
Do not use fresh and wet wood or biomass. The logs must have remained (be stored) in a dry and airy place for at least two years.
-
Do not drain the circulating water from the installation during the non-heating season.
After performing the installation, conduct (carry out) a 2•hour test of the installation in operating conditions. The certification by the installer for its implementation is an integral part of the warranty card.

OPERATING INSTRUCTIONS
Recommended fuel
Use only untreated chemically, natural wood, as well as wood briquettes without bonding adhesives.
It is important that the wood be dry. Dry wood is called that has humidity below 20%. This is achieved by storing in a dry and airy place for at least 2 years. Logs are stored shopped and arranged, as their thickness must be between 5 and 15 cm.
Why wet wood shouldn’t be used?
- Moisture in the wood reduces their heat when burning. Much of the heat is spent to evaporate the water, and the rest may turn out insufficient to provide the necessary heating. For example, 20 kg wet wood can mean 10 kg of dry wood and 10 liters of water, added to the fire.
- Water vapor decreases the combustion temperature and contributes to the formation of soot, which accumulates and forms a black solid layer on the walls of the combustion chamber, the glass ceramics, the pipes and the chimneys.
- Environmental pollution increases because the gases leave the chimney unburned.
Kindling
The purpose of kindling is to warm up the walls of the combustion chamber, the pipes and the chimney to create draft and a stable sustainable fire, as the task is to kindle it form the first attempt with a matchstick, without repeated addition of paper and kindlings.
- Before lighting, clean the ash from the grate.
- Fully open the primary air valve mounted on the door of the combustion chamber or the ashpan (see Diagram III – 2.1) and the valve for the flue gases (see Diagram III – 2.2).
- Put two chopped pieces of wood (logs) in the combustion chamber, parallel to one another, on both sides of the grate.
- Use paper, press it and place it on the front part of the grill between the logs. Do not use glossy, printed or impregnated paper.
- Place small dry kindlings on the paper. Easy-burning kindlings of softwood are preferred. Arrange the kindlings so that they do not collapse and suffocate (stifle) the emerging fire. Put some finely chopped wood on the kindlings.
- Light the paper. When the paper starts burning, close the combustion chamber door.
- Leave the primary air nozzles fully (entirely) open until the flame covers the entire combustion chamber, and close them completely after sustainable ignition. Otherwise certain surfaces may overheat above the permissible temperature. See the Warranty Conditions.
- During actual combustion, the secondary air that is sucked in through the openings in the upper periphery of the combustion chamber door is entirely sufficient.

Fuelling with wood
Wood burns best in cycles, so the heat radiated by the fire is not constant over time.
Cycle is the time from the ignition of the wood loaded on embers to their transformation into a new layer of embers. Each cycle can provide heating for several hours depending on how and how much wood is loaded.
Finely chopped pieces of wood, thrown crosswise, burn faster, because the incoming air is able to reach all surfaces at once (simultaneously). Such an arrangement is suitable when necessary intensive heat to be given off.
To achieve a continuous, prolonged, sustained stable fire, gather the coals on the grate and load wood. The dense, close, parallel arrangement of the wood prevents penetration of air and flames among them and preserves their interior for later burning. Open entirely (completely) the primary air. When the outermost wood kindles, reduce the air to achieve the desired intensity of burning.
The combustion chamber door must be closed during operation. When opening for additional fueling, close the primary air vents and make sure that embers do not fall out of the chamber.
Signs of proper burning
- Burning must run without in the presence of flames without smoking. Smoke is a product of incomplete combustion due to moist fuel, low temperature in the combustion chamber and low draft.
- There are refractory bricks in the fireplace, they must maintain their natural color in yellow-brown, but not black.
- With dried wood and sufficient primary air, immediate ignition must be achieved with each new refill.
- The glass ceramic of the door must remain clean even during prolonged operation.
- The gases coming out of the chimney must be transparent and white. Gray smoke indicates that there is smoldering and poor combustion.
Requirements for the flue (chimney)
The chimney is designed to draw the products of combustion from the stove and throw them away into the atmosphere outside the home.
The ascending draft or “draw” of the chimney is a result of the combination between its height and the difference in the temperatures of the flue gasses and the outside air.
The hot flue gas column in the chimney has smaller weight than the equivalent external cold air column, so the pressure at the beginning of the hot chimney is smaller than the external air pressure. This very small pressure difference creates draft.
Weaker draft is a prerequisite for difficult kindling, return of flue gases, and it is overcome with rapid kindling and burning of dry thin wildly burning sticks and paper. After lighting the fire and heating up the chimney, its draft increases. For economical mode and high efficiency after heating the chimney, the draft must be reduced to 5- 10Pa, but so that there is no return of exhaust gases (smoking) with the door closed.
The main causes for poor draft are:
- Accumulated soot inside the chimney, which reduce its cross-section (diameter) and increases the resistance of the rising exhaust (flue) gases;
- cracked chimney wall or loose rosette;
- loose smoke pipes, or pipes inserted deep into the chimney, thus reducing or clogging its cross-section;
- the use of one chimney with small draft by several stoves at close levels (in close proximity);
- Smoking also occurs when the weather outside has suddenly warmed up — the hot gasses from lighting the fire cannot flow (escape) through the cold chimney. In this case a bigger amount of fast burning kindlings (sticks and paper) are used. The same effect is obtained when trying to kindle a heater on the first (ground) floor, provided that the same or adjacent chimney is already being used by another heater on the top floor.
- In case of unsealed (not air-tight) ceiling or open windows on an upper floor, the effect “staircase-chimney” is obtained, creating a reverse draught.
- In case of a chimney located in an area of overpressure, obtained from (caused by) wind.
When properly connected, serviced and maintained, the solid fuel cooker does not emit toxic fumes into the room. If, however, this occurs due to above causes, to room is aired and the cause of the smoke must be found and remedied.
Don’t burn waste!
Burning garbage leads to unpredictable consequences because, unlike dry wood, garbage contains various substances that react when burn together. For example, household waste contains various colored papers and plastics. When you burn them, you do not destroy them, you only change their chemical composition by adding a whole cocktail poisons to the flue gases. The result is the same when burning any type of garbage, only the type of the discarded toxins changes. One of the products when burning papers and plastics is dioxin — a highly toxic chemical that does not degrade and enters the tissues of animals and humans. All manufactured fireplaces and stoves are designed and tested to work with dry wood without adhesives and paints. Plain paper may be used only during initial kindling.
The waste includes:
- household waste
- glued or painted wood
- plywood or laminated boards (plates) of pressed wood particles
- impregnated wooden sleepers
Maintenance, cleaning and preservation
When buying a fireplace, carefully carry it to the place where it will be installed, protecting it from mechanical damage and shocks.
During the first one or two ignitions, it is possible to release residual vapors from the baking of the heat resistant paint, which must be aired from the room. Use thermo-resistant gloves when you have to touch hot surfaces. Clean the ashpan daily. Do not dispose the ash in plastic containers (vessels). Regularly clean the flue cavities under the oven, around it, water jacket surfaces and the chimneys.
The painted surfaces are cleaned with a slightly damp cloth of natural materials only when the stove is turned off and cooled. Do not use cleaning detergents.
The thermoshock glass ceramics on the door of the combustion chamber or on the hob are wiped with a damp cloth in warm or cold condition and the tempered glasses of the oven only in cold condition.
Do not make any unauthorized changes in the construction! When repairing, use only original spare parts provided by the manufacturer The company maintains warranty and post-warranty service and replacement of water jackets.
