DAMLY SUNHEATER Automatic Gas Heater for Livestock and Poultry

Description

The DAMLY SUNHEATER series provides a reliable and effective heating solution for poultry houses, pig farms, and agricultural warehouses. These heaters are designed to be ON/OFF models with automatic ignition and are compatible with LPG, natural gas, or biogas. Their versatile design allows for installation both inside or outside farm buildings, ensuring that they meet the varied requirements of different livestock environments.

Key Features and Operation

• Sturdy Construction: Built with an AISI 304 stainless steel chassis or galvanized steel (depending on the model), these heaters are designed to withstand harsh farm conditions.
• Automatic Control: Equipped with a thermostat, the heaters start and stop automatically to maintain the desired temperature. When switched on, the fan begins, and after 10 seconds, the ignition electrode activates, starting the burner flame.
• Safe Operation: The flame sensor by ionization detects any loss of flame, automatically shutting off the gas valves to prevent potential hazards. The overheating thermostat and airflow switch provide additional layers of security.
• Easy Installation: These heaters must be mounted horizontally and positioned where there is sufficient space around them for proper airflow, maintenance, and repair. If installed outdoors, the heaters should be protected from elements such as rain, snow, and humidity.

Installation Guidelines

• Location: Ensure the heater is installed horizontally with unobstructed air inlets and outlets to maintain proper airflow.
• Structure Requirements: The farm building structure should be strong enough to support the heater and its accessories.
• Rigidity: Mount the heater securely to avoid tension on gas and electrical connections.
• Outdoor Use: When installed outdoors, protect the heater from adverse weather conditions, and ensure the electrical box is closed properly.

Gas Connections

• The gas connection is made with a 1/2-inch screw connection.
• It is crucial to use the correct gas type and pressure as indicated on the heater’s identification plate.
• Before initial operation, test for gas leaks and purge gas conduits to ensure safe gas distribution.
• It is recommended to install a gas filter at the beginning of the gas installation to maintain a clean gas supply.

Electrical Connections

• The heater is pre-wired according to its electrical diagram and operates on a single-phase 220V power supply.
• It should be connected to a switchboard with an ON/OFF heating output or directly to a thermostat (optional).
• A ground connection is required for safety. A red indicator light on the heater’s body will show when the heater is in security mode.
• Remote luminous and audible security indicators, as well as a remote reset option, are available for enhanced control.

Operating Instructions

• To start the heater, use the farm controller to switch it on. The heater will begin operating automatically, starting the fan first and igniting the burner flame after 10 seconds.
• Once the desired temperature is reached, the gas valve will close, and the fan will stop, ensuring efficient operation.

Safety Features

• Flame Sensor: Detects flame loss and automatically shuts off the gas supply to prevent leaks.
• Overheating Thermostat: Provides thermal protection, shutting down the heater if it overheats.
• Airflow Switch: Monitors fan operation, ensuring the proper ventilation and safety of the heating system.

Maintenance

• Perform regular maintenance after each batch of livestock to ensure the heater operates efficiently.
• Check air inlets and outlets for blockages to maintain proper air circulation.
• Verify the hot air can circulate freely inside the farm without obstruction.

Additional Safety Guidelines

• Gas Cylinder: Use gas bottles above 50 kg for efficient operation, and check for gas leaks every time the bottle is changed.
• Turning Off: For short periods, turn down the temperature from the farm controller. For longer stops, wait for the burner and fan to stop before closing the gas valve and cutting off the power supply.
