1. Introduction
Thank you for choosing the EconoHome Wall Mount Space Heater Panel. This 400W convection heater is designed to provide efficient and consistent ambient warmth for rooms up to 120 sq. ft. This manual provides essential information for the safe and effective installation, operation, and maintenance of your new heater.
The EconoHome heater operates on a principle of convection, where heat rises from behind the panel and circulates warm air throughout the room. This method ensures even heat distribution without drying out the air or circulating dust, making it suitable for individuals with asthma or dust allergies. It is also designed for quiet operation.

2. Safety Information
Please read all safety instructions carefully before installing or operating this heater. Failure to follow these instructions may result in electric shock, fire, or personal injury.
- Electrical Safety: Ensure the heater is connected to a 120V, 3.33 amp circuit. Do not overload electrical outlets. Avoid using extension cords.
- Placement: Install the heater on a flat, vertical wall surface. Maintain a minimum distance of 12 inches (30 cm) from any combustible materials (e.g., curtains, furniture, bedding).
- Heat Guard: The included heat guard cover accessory is crucial for safety and efficiency. It helps direct convection currents and keeps the exterior casing safe to touch. Always install the heat guard.
- Ventilation: Do not block the air vents or cover the heater with any material. This can lead to overheating and fire hazards.
- Water Exposure: Do not install the heater near water sources, such as sinks, showers, or swimming pools. Do not operate the heater with wet hands.
- Children and Pets: Keep children and pets away from the heater during operation. Although the heat guard keeps the surface safe to touch, supervision is recommended.
- Damage: Do not operate the heater if it has a damaged cord or plug, or if it has malfunctioned or been dropped. Contact customer support for assistance.
- Intended Use: This heater is for indoor use only. Do not use it for commercial or industrial purposes.
3. Setup and Installation
The EconoHome Wall Mount Space Heater Panel is designed for easy installation. All necessary mounting hardware is included.
3.1 Unpacking
- Carefully remove all components from the packaging.
- Verify that all parts are present: heater panel, mounting hardware (screws, anchors, plastic nuts), adjustable plug-in thermostat, and heat guard cover.
- Inspect the heater for any signs of damage. Do not proceed with installation if damage is observed.
3.2 Mounting Location
- Choose a wall location that is clear of obstructions and combustible materials.

3.3 Installation Steps
- Marking: Hold the heater panel against the desired wall location. Use a pencil to mark the positions for the four mounting holes.
- Drilling: Drill pilot holes at the marked locations. For drywall, use appropriate anchors. If mounting into studs, ensure proper screw length.
- Mounting Pins: Insert the mounting pins into the drilled holes.
- Attach Heat Guard: Before securing the heater, attach the heat guard cover to the back of the panel. This accessory is designed to create an air gap between the heater and the wall, enhancing convection and preventing excessive heat transfer to the wall.
- Secure Heater: Align the heater panel with the mounting pins. Secure the panel by threading and tightening the plastic nuts onto the pins. Ensure the heater is firmly attached to the wall.
- Thermostat Connection: Plug the heater's power cord into the adjustable plug-in thermostat. Then, plug the thermostat into a standard 120V electrical outlet.
Note: This unit may also be hard-wired by a qualified electrician if desired. Consult a professional for hard-wiring instructions.

- Cleaning: Before cleaning, always unplug the heater and allow it to cool completely. Wipe the exterior surface with a soft, damp cloth. Do not use abrasive cleaners, solvents, or immerse the heater in water.
- Storage: If storing the heater for an extended period, ensure it is clean and dry. Store it in a cool, dry place, preferably in its original packaging.
- Inspection: Periodically inspect the power cord and plug for any signs of damage. If damage is found, discontinue use and contact customer support.
- Paintable Surface: The heater panel features a paintable design. If you choose to paint it, ensure the paint is heat-resistant and non-flammable. Allow paint to dry completely before operating the heater.
