Mr. Heater support FAQ
Common questions about manuals, registration, and support for this brand.
-
How do I light the pilot on my Mr. Heater portable unit?
Rotate the control knob to the 'Pilot' position and depress it. Hold the button down for 30–60 seconds. This heats the thermocouple and allows the pilot flame to stay lit required for operation.
-
Why does my heater shut off automatically?
Mr. Heater units are equipped with safety features like the Oxygen Depletion Sensor (ODS) and a tip-over switch. The heater will shut off if it detects low oxygen levels or if the unit is tilted beyond a safe angle.
-
Can I use Mr. Heater products indoors?
Many portable units, such as the 'Buddy' series, are classified as indoor-safe for recreational enclosures due to their ODS technology. However, adequate ventilation (e.g., a window or roof vent) is required. Always check your specific manual for usage restrictions.
-
What should I do if I smell gas while using the heater?
Do not attempt to light the appliance. Extinguish any open flame, shut off the gas supply immediately, and evacuate the area. Contact your gas supplier or fire department from a safe distance.
-
Does the heater work at high altitudes?
At altitudes above 7,000 feet, the reduced oxygen levels may inadvertently trigger the Oxygen Depletion Sensor (ODS), causing the unit to shut off. This is a safety feature and not a malfunction.
