Safety Instructions and Warnings
Operating the Mr. Heater Big Buddy requires strict adherence to safety instructions to prevent accidents. Never leave the heater unattended while burning! Always ensure adequate combustion and ventilation. Refer to the manual for specific ventilation requirements to prevent carbon monoxide poisoning.
Every time a hose or tank is connected to the unit, check for leaks using soapy water, looking for bubbles, listening for hissing sounds, feeling for extreme cold, or smelling for gas odors. Replace the fuel filter annually with hose No. F273701, F273702, or F272702. Hose No. F273704 (Buddy series hose) does not require a fuel filter.
Be aware of fuel gas odor and odor fading. If you smell gas, immediately shut off the heater and ventilate the area. Odor fading can occur, making it difficult to detect leaks, so regular inspections are crucial.
The heater area must be kept clear of combustible materials. Use only Mr. Heater approved parts and accessories. Improper use can lead to fire, explosion, or carbon monoxide poisoning. Always follow the operating instructions and owners manual provided.
Lighting and Operating Instructions
To safely light and operate the Mr. Heater Big Buddy, follow these instructions carefully. Ensure the heater is placed on a stable, level surface, away from combustible materials, maintaining clearances of 30 inches from the top, 24 inches from the front, 6 inches from the sides, and 0 inches from the rear.
Connect either one or two 1-lb propane cylinders or a remote cylinder (maximum 20 lbs) using a Mr. Heater hose. For remote cylinders, ensure the hose connection to the quick disconnect fitting is regulated to 11 W.C. pressure.
To light the heater, turn the control knob to the “Pilot” position and push down while clicking the igniter until the pilot light ignites. Hold the knob down for 30 seconds after ignition. Then, turn the knob to the desired heat setting: LO (4,000 BTU/Hr), MED (9,000 BTU/Hr), or HI (18,000 BTU/Hr).
To shut down, turn the control knob to the “Pilot” position and push down, then turn it to the “Off” position. Disconnect the propane cylinder(s) when not in use and store in a well-ventilated area.
Connecting to a Remote Propane Cylinder
To connect your Mr. Heater Big Buddy to a remote propane cylinder, ensure you have the correct hose assembly. It’s essential to use a Mr. Heater hose equipped with a quick disconnect fitting and a regulator to maintain a consistent 11 inches of water column (W.C.) pressure. The remote cylinder should not exceed 20 lbs in size for safety and optimal performance.
Begin by securely attaching the hose to the propane cylinder, tightening the connection to prevent leaks. Next, connect the quick disconnect fitting on the hose to the corresponding fitting on the heater. Always check for leaks using soapy water, looking for bubbles around the connection points. Listen for any hissing sounds or feel for a cold sensation, indicating escaping gas.
Once the connection is confirmed leak-free, you can proceed with the standard lighting instructions. Remember to inspect the hose and connections regularly for any signs of wear or damage, replacing them as needed to ensure safe operation. Using the correct hose and fittings is crucial for the safe and efficient use of your Mr. Heater Big Buddy with a remote propane cylinder.
Maintenance Procedures
Regular maintenance is crucial for ensuring the longevity and safe operation of your Mr. Heater Big Buddy. Always keep the heater area clear of combustible materials. Before each use, inspect the heater for any signs of damage, such as cracks, dents, or loose connections. Pay close attention to the hose and regulator, replacing them annually or if any damage is detected.
Periodically clean the burner and pilot assembly. If the pilot light appears yellow or the burner has a noticeable flame, cleaning may be required. Use a soft brush or compressed air to remove any dust or debris from these components. Replace the wire guard if it becomes damaged or corroded to prevent accidental contact with hot surfaces.
When storing the heater, disconnect it from the propane source and store it in a dry, well-ventilated area. Ensure the heater is protected from direct sunlight and extreme temperatures. If using a fuel filter, replace it annually to prevent clogs and maintain optimal performance. Following these maintenance procedures will help keep your Mr. Heater Big Buddy functioning safely and efficiently for years to come.
Troubleshooting Common Issues
Encountering issues with your Mr. Heater Big Buddy? Here’s a guide to troubleshoot common problems. If the heater fails to light, first ensure the propane tank has sufficient fuel. Check the igniter; if it’s not sparking, replace the battery or clean the igniter tip. A clogged pilot light can also prevent ignition; carefully clean it with a thin wire.
If the heater lights but produces a weak flame, inspect the gas line for kinks or obstructions. Low propane pressure, especially in cold weather, can also cause a weak flame. Try warming the propane tank or using a larger tank. If the heater emits a strong odor, ensure adequate ventilation and check for gas leaks using soapy water on connections.
For uneven heating, ensure the heater is placed on a level surface and away from drafts. If the heater shuts off unexpectedly, check the safety shut-off valve; it may have been triggered by low oxygen levels or a tip-over. Reset the valve and ensure proper ventilation. If problems persist, consult the manual or contact Mr. Heater customer service for assistance.
Understanding Fuel Gas Odor and Odor Fading
Propane, in its natural state, is odorless. To ensure safety, a distinct odorant, similar to rotten eggs, is added to propane so leaks can be easily detected. It’s crucial to familiarize yourself with this smell.
Odor fading, or odor loss, can occur when propane sits in a tank for an extended period. The odorant can dissipate or be absorbed by the tank walls, reducing its concentration. This makes leak detection more difficult. Several factors contribute to odor fading, including rust inside the tank, exposure to air and moisture, and selective adsorption.
If you suspect odor fading, do not rely solely on smell to detect leaks. Regularly inspect connections with soapy water and consider installing a propane gas detector. If you smell gas, even faintly, evacuate the area immediately and contact a qualified professional. Always prioritize safety and address any concerns promptly to prevent potential hazards associated with undetected propane leaks.
