5. Installation Requirements
Installation of the Prity FGW15 stove must be carried out by a certified professional in accordance with all national and local building and fire safety regulations. This includes proper chimney connection, flue pipe installation, and integration with your central heating system.
5.1 Chimney and Flue Pipe
- Ensure the chimney is clean, structurally sound, and of adequate height and diameter for the stove's output.
- The flue pipe diameter is 130 mm. Use appropriate connectors and seals.
- All flue pipe connections must be airtight to prevent smoke leakage.
5.2 Water Connections for Back Boiler
The back boiler requires connection to a closed or open central heating system. The cold water inlet and hot water outlet connections are 2.5 cm (1 inch). A qualified plumber must perform these connections, ensuring proper pressure relief valves, expansion tanks, and circulation pumps are installed according to system requirements and local codes.
5.3 Positioning and Clearances
Refer to Section 2.2 for minimum clearances to combustible materials. The stove must be placed on a non-combustible hearth extending beyond the appliance as required by local regulations.
6. Operating Instructions
Before operating, ensure all installation checks are complete and the central heating system (if connected) is filled and vented.
6.1 Starting the Fire
- Open both the front air supply damper and the smoke damper fully.
- Place a small amount of kindling and firelighters on the cast iron grate in the firebox.
- Light the kindling. Once it is burning well, add small pieces of dry firewood.
- Close the firebox door securely.
- Allow the fire to establish fully before adding larger logs.
6.2 Air Control and Flame Intensity
The stove is equipped with two manual dampers:
- Front Damper: Controls the primary air supply to the combustion chamber. Opening it increases the burn rate and heat output. Closing it reduces the burn rate.
- Smoke Damper: Regulates the intensity of the flame and the draft through the flue. Adjust this to achieve optimal combustion and prevent excessive heat loss up the chimney.
Adjust both dampers to achieve a steady, efficient burn. A bright, lively flame indicates good combustion. Excessive smoke or a dull, smoldering fire suggests insufficient air or poor draft.
6.3 Using the Oven
The oven utilizes heat from the firebox below. The oven temperature will vary depending on the intensity of the fire. Monitor the oven temperature gauge and adjust the fire's intensity as needed for cooking. Preheat the oven thoroughly before placing food inside.
7. Maintenance
Regular maintenance is crucial for the safe and efficient operation of your Prity FGW15 stove.
7.1 Ash Removal
Remove ash from the ash drawer regularly, ideally before each use or when the ash bed becomes thick. Allow the stove to cool completely before removing ash. Dispose of ash in a metal container with a tight-fitting lid, away from combustible materials.
7.2 Glass Cleaning
Clean the ceramic glass on the firebox and oven doors as needed. Use a specialized stove glass cleaner or a damp cloth dipped in fine ash (when cold) to remove soot. Avoid abrasive cleaners or tools that could scratch the glass.
7.3 Flue Pipe and Chimney Cleaning
The flue pipe and chimney must be inspected and cleaned by a qualified chimney sweep at least once a year, or more frequently if heavy use or creosote buildup is observed. Blockages can lead to dangerous chimney fires and carbon monoxide accumulation.
7.4 General Inspection
Periodically check all seals, hinges, and dampers for wear or damage. Ensure water connections for the back boiler are free from leaks. Replace any worn parts promptly.
8. Troubleshooting
This section addresses common issues you might encounter with your Prity FGW15 stove.
| Problem | Possible Cause | Solution |
|---|---|---|
| Smoke entering the room | Blocked chimney/flue, insufficient draft, door opened too quickly, wet fuel. | Check chimney/flue for blockages. Ensure dampers are open. Use dry fuel. Open door slowly. |
| Low heat output | Insufficient air supply, wet fuel, small fire, poor insulation. | Open air dampers. Use dry, seasoned wood. Build a larger fire. Check room insulation. |
| Fire burns too quickly | Excessive air supply, door not sealed properly. | Close air dampers partially. Check door seals and replace if necessary. |
| Glass blackens quickly | Wet fuel, insufficient air for combustion, low burning temperature. | Use dry fuel. Increase air supply. Ensure fire burns hot enough. |
| Central heating not heating effectively | Low fire intensity, air in system, pump malfunction, system blockage. | Increase fire intensity. Bleed radiators. Check circulation pump. Consult a plumber. |
