Understanding Mr․ Heater Models
Mr․ Heater offers a variety of models, each designed with specific heating capacities and features․ The Little Buddy (MH5B, MH7B) is a compact, portable option, perfect for enclosed spaces up to 100 cubic feet, delivering 5,000 or 7,000 BTUs․ Conversely, the Big Buddy (MH18B) provides significantly more heat, capable of warming up to 400 cubic feet with an 18,000 BTU output, and often features dual fuel capabilities․
Beyond these core models, Mr․ Heater produces units tailored for workshops, garages, and construction sites, offering higher BTU outputs and robust construction․ Understanding the BTU rating is vital – higher BTUs mean greater heating power, but also increased propane consumption․ Always select a model appropriate for the size of the space and intended use, prioritizing safety and efficiency․ Refer to the product label for specific model details and heating capacity․
Safety Precautions for Mr․ Heater Use
Prioritize safety when operating a Mr․ Heater․ Never use indoors or in enclosed spaces without adequate ventilation, as this can lead to carbon monoxide poisoning – a potentially fatal hazard․ Always use a carbon monoxide detector․ Ensure the heater is placed on a stable, level surface, away from flammable materials like curtains and furniture․
Regularly inspect the hose and connections for leaks, and never operate a heater with a damaged hose․ Keep children and pets away from the heater during operation․ Do not modify or tamper with the heater in any way․ Be aware of the potential for the valve to leak, creating a fire hazard․ Follow all manufacturer’s instructions and warnings detailed in this manual․
Connecting to a Propane Tank
Proper propane tank connection is crucial for safe and efficient Mr․ Heater operation․ Ensure the heater is turned off before connecting or disconnecting a tank․ Use a POL (Pressure Operated Locking) regulator designed for propane appliances․ A standard 20 lb propane tank is commonly used, but larger options like 30 lb and 40 lb tanks are also compatible, offering extended run times․
Inspect the hose for cracks or damage before each use․ Hand-tighten the connection securely, avoiding the use of tools which can over-tighten and damage the valve․ Verify there are no leaks by applying a soapy water solution to the connection – bubbles indicate a leak․ Always store propane tanks outdoors in a well-ventilated area․
20 lb Propane Tank Connection
Connecting to a standard 20 lb propane tank is straightforward, but requires careful attention to safety․ First, ensure the Mr․ Heater unit is completely off and cool․ Locate the propane tank’s valve and remove the protective cap․ Slowly screw the POL regulator, pre-attached to the heater’s hose, onto the tank valve, turning it clockwise until hand-tight – do not use tools․
Crucially, after connecting, perform a leak test․ Mix soapy water and apply it liberally to the connection point․ If bubbles appear, immediately turn off the propane tank and tighten the connection further․ If the leak persists, discontinue use and contact Mr․ Heater customer support at (800) 964-4328; A secure connection is paramount for safe operation․
Larger Propane Tank Options (30 lb, 40 lb)
Utilizing 30 or 40 lb propane tanks with your Mr․ Heater extends runtimes, ideal for prolonged use or emergency preparedness․ However, these larger tanks necessitate an adapter hose, as the standard 20 lb regulator won’t directly connect․ Ensure the adapter is specifically designed for propane heaters and is CSA certified for safety․
Proper installation is vital․ Connect the adapter to the larger tank’s valve, following the same hand-tightening procedure as with a 20 lb tank․ Always perform a leak test with soapy water after connection․ Remember, longer hoses require extra caution to prevent tripping hazards and damage․ Refer to www․mrheater․com for compatible adapter recommendations and detailed instructions․

Lighting a Mr․ Heater: Step-by-Step Instructions
Before lighting, ensure adequate ventilation and confirm the heater is on a level surface․ First, fully open the propane tank valve․ Next, turn the heater’s control knob to the “Pilot” position and press and hold the knob․ Simultaneously, press the igniter button repeatedly until you hear a clicking sound and see the pilot light ignite․ Continue holding the knob for approximately 30-60 seconds after ignition․
If the pilot doesn’t light after several attempts, turn off the heater, wait five minutes, and repeat the process․ Once the pilot is stable, release the knob and turn it to the desired heat setting․ Always observe the flame and ensure it’s blue and steady․ Refer to your specific model’s manual for detailed diagrams and safety precautions․
Troubleshooting Common Issues
If your Mr․ Heater won’t light, first check the propane tank level and ensure the valve is fully open․ Verify the igniter button is functioning correctly by listening for a clicking sound․ Inspect the pilot assembly for any debris or obstructions․ A buildup of carbon can also restrict gas flow, requiring cleaning of the burner assembly․
Flame issues, such as a yellow or flickering flame, often indicate insufficient oxygen or a dirty burner․ Ensure adequate ventilation and clean the burner according to the manual’s instructions․ For persistent problems, contact Mr; Heater customer support at (800) 964-4328 or consult www․mrheater․com for further assistance and potential repair options․
Heater Won’t Light
When your Mr․ Heater fails to ignite, begin by confirming a full propane tank and a completely open tank valve․ Next, meticulously check the igniter button; a distinct clicking sound signifies functionality․ If no click is heard, the igniter may require replacement․ Inspect the pilot assembly for any obstructions like dust or debris that could hinder ignition․
Ensure the thermocouple is positioned correctly near the pilot flame, as this is crucial for maintaining gas flow․ A weak battery in models with electronic ignition can also be the culprit․ If issues persist, consult the manual or contact Mr․ Heater support at (800) 964-4328 or www․mrheater․com for expert guidance․
Flame Issues & Carbon Buildup
A yellow or weak flame often indicates insufficient oxygen or a buildup of carbon․ Ensure adequate ventilation, as Mr․ Heaters require fresh air for proper combustion․ Carbon buildup restricts airflow, leading to incomplete burning and potential safety hazards․ Regularly inspect the burner for soot or carbon deposits and carefully clean them according to the manual’s instructions․
If carbon buildup is excessive, it may signal a need for professional servicing․ A strong, blue flame is the desired outcome, signifying efficient combustion․ Contact Mr․ Heater at (800) 964-4328 or visit www․mrheater․com if flame issues persist, as they could indicate a malfunctioning component requiring replacement or repair․
Maintaining Your Mr․ Heater
Regular maintenance is crucial for safe and efficient operation․ Periodically inspect the heater for any signs of damage, such as cracks or leaks in the hose or connections․ Clean the exterior with a damp cloth and mild detergent, avoiding abrasive cleaners․ Check the burner assembly for obstructions and remove any debris․
Inspect and, if necessary, replace the propane regulator and hose according to the manufacturer’s recommendations․ Proper storage is also vital; ensure the unit is clean and dry before storing it in a well-ventilated area․ Refer to your Mr․ Heater manual for specific maintenance schedules and procedures, and contact customer support at (800) 964-4328 or www․mrheater․com for assistance․
Carbon Monoxide Detection
Carbon monoxide (CO) is a colorless, odorless, and deadly gas produced by incomplete combustion․ Mr․ Heater units, while designed for safety, must be used with a working CO detector․ Install a battery-operated or battery backup CO alarm in the same room as the heater, following the manufacturer’s instructions for placement and operation․
Test the CO alarm regularly to ensure it’s functioning correctly․ Be aware of the symptoms of CO poisoning, including headache, dizziness, nausea, and confusion․ If the alarm sounds, immediately extinguish the heater, evacuate the area, and call emergency services․ Never ignore a CO alarm, and always prioritize safety when using a propane or gasoline-fueled heater․
