Installation Instructions

Installation should be carried out by a certified electrician or a person possessing the required expertise. Ensure that the heater is installed correctly before activating the power.

HEATER LOCATION

When choosing a location for your new heater, ensure that the general instructions are followed. Your heater must be properly installed before operation. Do not prop the heater up against objects or use the heater with the grill placed vertically. For best effect, install the heater out of direct sunlight.

• Basement or Garage Use
• The heater can be utilized in a finished basement with drywall and carpet. For other scenarios, consider Heat Storm Outdoor Infrared Heaters. Visit heatstorm.com for details.
• Vaulted or Cathedral Ceilings
• The heater can be used with vaulted or cathedral ceilings. However, initial room heating may take longer. Once the desired temperature is reached, the heater will cycle accordingly.
• Poorly Insulated Areas
• Note that rooms with poor insulation may not retain heat efficiently, potentially leading to longer or more frequent operation.
• Cold Climate Installation Note
• Placing the unit under a window or on a poorly insulated wall may result in the heater reading a colder ambient temperature than the actual room temperature.
• Heating Multiple Rooms
• Effectiveness depends on floor plan openness and room sizes. Experiment to find the most suitable configuration. DO NOT USE in the Following Areas:
  • Outdoors – use Heat Storm Outdoor Infrared Heaters.
  • Locations with gasoline, paint, or flammable liquids.
  • Wet or moist locations.
  • Closets.

POWER CONNECTION GUIDELINES

This heater is wired for an outlet, or the cord can be cut to hardwire the heater. Heat Storm Infrared Heaters are considered to be an appliance. Each heater and appliance should be on its own circuit. Plug the heater directly into a wall outlet; do not use extension cords, surge protectors, or relocatable power taps. This heater is designed for standard 120-volt outlets and should only be connected to a proper 3-prong polarized outlet. Ensure the cord is not under carpeting, covered with rugs, runners, or similar coverings. Avoid routing it under furniture or appliances and position it away from high-traffic areas to prevent tripping hazards.

TOOLS NEEDED FOR INSTALLATION

• Drywall saw
• Utility knife
• Wire cutter and stripper for hardwiring
• Phillips screwdriver

Troubleshooting Guide

RECALIBRATING YOUR HEATER

If your heater is not working like normal, try resetting it. Heaters are like other electronics; sometimes they need a reboot (refer to the factory reset on page 11). If an issue persists, contact customer service at 435-752-6611.

FAN

• Not Blowing Air

  When powering the heater ON, it does not blow any air at first. The initial 15 seconds allow the infrared elements to heat up, ensuring that when the fan turns on, warm air is circulated into the room.

• Not Blowing Warm Air

  Ensure the air inlet is not blocked. The ambient temperature (displayed) is higher than the thermostat setting. Something is blocking the airflow. Move the object out of the way of the heater. This is common if the heater is in a closet or under a desk.

• Continuing to Blow Air When Heater Is Turned Off

  This is the cool-down phase. The heater will run for several minutes (up to 12) to cool the internal components. This increases the lifespan of the infrared elements. If the heater did not finish the cooling procedure when it was unplugged, the fan will blow immediately when the heater is powered back on. Heater Fails to Reach the Set Temperature and Continues to Run. Possible reasons for temperature discrepancies:

  • Ensure clean filters.
  • Address drafty or poorly insulated rooms.
  • Keep doors closed for efficient heating.
  • Place the heater on an interior wall, away from windows.
  • If issues persist, consider the heater's size suitability for the room. Optimal for spaces between 150–750 sq. ft., with primary heating around 150 sq. ft.

  Square footage recommendations may vary based on home insulation. Placing the heater near objects can impede air circulation in the room, resulting in uneven temperatures within the same space. Unplug the unit from the wall outlet for 2 hours. Reconnect the unit after this period. If the issue persists, contact customer service at 435-752-6611.

• Fan Runs for Under a Minute and Then Turns Off

  The fan is turning on to attempt to create airflow within your room. The heater is trying to determine if the ambient temperature in the room has changed.

THERMOSTAT CALIBRATION

Ambient Temperature Reading of the Heater Different from the Reading on My Central Heating Thermostat. Thermostat readings may fluctuate depending on the surroundings. You can manually calibrate the thermostat on the heater to align with your central HVAC system. You may need to attempt calibration multiple times to align your heater thermostat with your HVAC system.

1. In the Smart Life app, tap on your heater to enter the temperature adjustment screen. Press the icon to enter the temperature calibration page.
2. Adjust the Heat Storm's thermostat with the slider to reach the same temperature as your central HVAC.

NOTE: Generally, Heat Storm heater thermostats are more precise than home central thermostats. Adjusting your Heat Storm heater to align with your central system may result in reduced efficiency.
