  If your DR. Heater Heater isn't heating, it might be because the overheat protection has temporarily turned it off. To fix this, turn the heater OFF, check for anything near it that could be causing high temperatures, and wait for it to cool down before turning it back on. Alternatively, the room temperature may have reached the thermostat setting. If you want to increase the room temperature, simply adjust the Thermostat Control knob to a higher setting.

  If your DR. Heater Heater produces a burning smell, make sure there are no flammable materials within 0.9 meters (3 feet) of it. If there are, remove them. Also, ensure the room is well-ventilated, as the smell might be due to a drop of oil on the heating coil during manufacturing, which should evaporate quickly. Finally, ensure there's at least 36 inches (90 cm) of space between the sides and rear of the heater and any walls; if not, reposition the heater.

  If your DR. Heater Heater is not heating, it could be due to a couple of reasons. First, the overheat protection might have temporarily deactivated the heater, in which case the alarm LED will flash. To resolve this, turn the heater off, check for any obstructions around it that could be causing high temperatures, and wait for it to cool down before turning it back on. Alternatively, the room temperature may have reached the thermostat setting. If you want to increase the room temperature, simply adjust the thermostat control knob to a higher setting.

  If your DR. Heater Heater is producing a burning smell, there are a few potential causes. First, check to ensure that there are no combustible materials within 0.9 meters (3 feet) surrounding the heater and remove any if found. Second, it's possible that a drop of oil fell on the heating coil during manufacturing; this should evaporate quickly, so ensure the room is well ventilated. Finally, make sure there is a minimum clearance of 36 inches (90 cm) from both sides and the rear of the heater to the adjacent walls; reposition the heater if needed to provide enough space.

This document is an owner's manual for the Dr. Heater Infrared Fan Forced Greenhouse Heater, models DR218-1500 and DR218-3000. It provides important safety instructions, specifications, operating instructions, maintenance guidelines, troubleshooting tips, and frequently asked questions.

Function Description:

The Dr. Heater Infrared Fan Forced Greenhouse Heater is designed to provide supplemental heating for greenhouses. It utilizes infrared heating technology combined with a fan-forced system to distribute warmth. The heater is equipped with a thermostat control to regulate ambient temperature and a power setting control to adjust heat output. It features a "Cool-Touch" cabinet for safety and a power indicator light. The primary function is to maintain a desired temperature within a greenhouse environment, helping to protect plants from cold temperatures.

Important Technical Specifications:

Model DR218-1500:
- Voltage: 120V
- Watts: 1500W
- Frequency: 60Hz
- BTU Rating: Approximately 5200 BTUs
- Kilowatts per hour: Approximately 1.5 kWh
- Plug Type: 3-prong grounded plug for 120V 15 amp or higher circuit receptacle. An adapter for two-slot receptacles is available, provided the green grounding lug is connected to a permanent ground.
Model DR218-3000:
- Voltage: 240V
- Watts: 3000W
- Frequency: 60Hz
- BTU Rating: Approximately 10400 BTUs
- Kilowatts per hour: Approximately 3 kWh
- Plug Type: 240-volt grounding plug (NEMA 6-20R) for a 240V 15 amp or higher circuit receptacle. No adapter is available or should be used for this configuration.
Thermostat Temperature Range (both models): 32°F to 104°F (0°C to 40°C)
Safety Features: Overheat protection system that shuts off the unit if parts become excessively hot.

Usage Features:

Controls:
- Thermostat Control: Allows users to set a desired ambient temperature. The heater will cycle on and off to maintain this setting. To set, turn the knob to MAX, allow the room to warm, then slowly turn the knob counterclockwise until the heater turns off.
- Power Setting Control:
  - DR218-1500: Offers "HEAT," "FAN," and "OFF" settings.
  - DR218-3000: Offers "HIGH," "LOW," "FAN," and "OFF" settings.
- Power Indicator: A light that indicates when the unit is receiving power.
Initial Operation: A trace of smoke or odor may occur during the first operation due to manufacturing oil on the heating coil; this is normal and will quickly dissipate. Small cracking sounds may also be heard initially. Ensure the room is well-ventilated during this period.
Placement: Must be used on flat, dry surfaces. Keep combustible materials (furniture, pillows, bedding, papers, clothes, curtains) at least 3 feet (0.9m) from the front, sides, and rear of the heater. Not intended for outdoor use or in bathrooms, laundry areas, or similar indoor locations where it could fall into water.
Connection: Always plug directly into a wall outlet/receptacle. Never use with an extension cord or relocatable power tap (outlet/power strip).
Disconnection: To turn off, set controls to OFF, then remove the plug by grasping it and pulling it from the outlet; never yank on the cord. Unplug when not in use.
Hyperthermia Warning: Avoid excessive room temperatures. Do not leave the product running unattended in confined spaces around infants or individuals with reduced physical, sensory, or mental capabilities. Symptoms of hyperthermia include high body temperature, headache, nausea, vomiting, tiredness, dizziness, fainting, and rapid pulse. If these symptoms occur, turn off the heater and seek medical attention.
Airflow: Ensure the rear intake is not blocked and the filter is clean to maintain proper airflow.
Multiple Heaters: Multiple heaters can be used simultaneously, but each should be on its own dedicated circuit to prevent overloading.
Moving the Heater: It is not recommended to move the heater while it is operating. Move only when the fan has completely turned off.

Maintenance Features:

Cleaning:
- Always turn OFF the heater and disconnect the cord from the electrical outlet before cleaning.
- Light dust accumulation can be removed with a soft cloth or vacuum cleaner.
- Wipe exterior surfaces occasionally with a damp (not dripping wet) cloth using a mild detergent and water. Dry the case thoroughly before operation.
- CAUTION: Do not allow water to run into the interior of the heater to prevent fire or electric shock.
Lubrication: The fan motor is factory-lubricated for life and requires no further lubrication.
Storage: Store the heater in a clean, dry place when not in use.
Filter Maintenance: The manual advises following a filter maintenance procedure to clean the filter, though specific steps for filter cleaning are not detailed in the provided excerpts.

Safety Precautions:

Do not touch hot surfaces with bare skin. Use handles if provided.
Do not operate with a damaged cord or plug, or if the heater malfunctions, has been dropped, or damaged. Return to an authorized service facility for repair.
Do not run the cord under carpeting, throw rugs, or furniture, or in traffic areas to avoid tripping hazards.
Do not insert foreign objects into ventilation or exhaust openings.
Do not block air intake or exhaust openings.
Do not use in areas where gasoline, paint, or flammable liquids are used or stored.
Never clean the heater while it is plugged in. Do not immerse in water.
Ensure the electrical outlet is in good condition. A warm plug or cord may indicate a worn outlet, which should be replaced to prevent overheating or fire.
Do not use a cord adapter or remove the grounding plug if you do not have a grounded outlet. Contact a licensed electrician. Removing or altering any part of the heater is unsafe and voids the warranty.
