Always follow the manufacturer’s guidelines for safe operation. Install the heater according to the manual, ensure proper ventilation, and keep it away from flammable materials. Never leave the heater unattended while in use. Place it on a stable, level surface and avoid overhanging objects. Keep children and pets at a safe distance. Do not use the heater in enclosed spaces without adequate ventilation, as it consumes oxygen and produces carbon monoxide. Regularly inspect for damage or wear. If unsure about any aspect, consult the manual or contact customer support. Remember, safety is paramount to prevent accidents and ensure efficient heating.
Odor Fade Warning and Ventilation Requirements
The Mr. Heater Big Buddy may produce an odor during operation, especially when new. This is normal due to the combustion process. Ensure proper ventilation in the room to prevent odor buildup. Open windows or use fans to maintain airflow. Inadequate ventilation can lead to carbon monoxide accumulation, posing serious health risks. The heater requires a well-ventilated area to function safely and efficiently. Always follow the ventilation guidelines outlined in the manual to ensure a safe environment while using the heater. Proper airflow is crucial for both odor reduction and user safety.
Clearance to Combustibles
The Mr. Heater Big Buddy requires specific clearance from combustible materials to ensure safe operation. Maintain a minimum clearance of 30 inches from the top, 24 inches from the front, and 6 inches from the sides. The rear of the heater can be placed directly against a non-combustible surface. Keep all flammable materials, such as curtains, bedding, or furniture, away from the heater. Proper clearance prevents fires and ensures efficient heat distribution. Always follow the manufacturer’s guidelines for placement and installation. Failure to maintain adequate clearance may result in fire hazards or damage to the heater. Ensure the heater is placed on a stable, non-combustible surface for optimal safety.
Operating Instructions
Light the heater by following the ignition procedure, then adjust the control knob for desired heat output. Ensure the pilot stays lit before releasing the knob.
Lighting the Heater
To light the Mr. Heater Big Buddy, ensure the control knob is in the “OFF” position. Open the propane cylinder valve slowly. Turn the control knob to “PILOT” and press, then light the pilot with a match or lighter. Hold the knob down for 30 seconds to heat the thermocouple. Once the pilot is lit, release the knob and adjust the heat setting as needed. If the pilot does not light on the first attempt, repeat the process. Always follow safety guidelines to avoid hazards.
Using the Control Knob and Fan Switch
Locate the control knob and fan switch on the front of the Mr. Heater Big Buddy. The control knob has three main positions: OFF, PILOT, and HI; Turn the knob to “PILOT” to light the heater, then press and hold until the pilot ignites. Once lit, release the knob and adjust to your desired heat setting. The fan switch, located nearby, can be turned on to circulate warm air more efficiently. Use the fan switch to optimize heat distribution in larger spaces. Always ensure the knob is in the “OFF” position when not in use to conserve propane and ensure safety.
Connecting to a Remote Propane Cylinder
To connect your Mr. Heater Big Buddy to a remote propane cylinder, first ensure the cylinder is located outdoors and upright. Attach the provided propane hose to the heater’s connection point, ensuring it is securely fitted. Next, connect the other end of the hose to the propane cylinder’s regulator. Turn the cylinder’s valve counterclockwise to release propane. Check for leaks by applying soapy water to the connections—bubbles indicate a leak. Once secure, light the heater following the standard ignition procedure. Always maintain a safe distance from open flames and ensure the area is well-ventilated. Never leave the heater unattended while in operation.
Maintenance and Troubleshooting
Regularly inspect and clean the burner and wire guard to ensure proper function. Address issues like yellow flames or low heat by referencing the troubleshooting guide.
Routine Maintenance Tasks
Regular maintenance is crucial for optimal performance and safety. Inspect the burner assembly and wire guard for debris or soot buildup, cleaning them as needed. Ensure the pilot orifice is free from obstructions. Check the propane hose for any signs of damage or wear, replacing it if necessary. Always store the heater in a dry, well-ventilated area when not in use. Refer to the manual for specific cleaning and inspection procedures. Perform these tasks annually or before extended periods of storage to maintain efficiency and reliability. Proper upkeep ensures your Mr. Heater Big Buddy operates safely and effectively for years to come.
Replacing the Wire Guard and Burner Assembly
To replace the wire guard, carefully remove it by bending it gently and lifting it off. Inspect the burner assembly for damage or wear. If damaged, disconnect the propane supply before proceeding.
