Safety is a significant strength of this model, featuring auto shut-off mechanisms if tipped over, when the pilot light goes out, or if it detects low oxygen levels, providing peace of mind during use. Portability is another advantage, as it’s designed to be easily moved around. However, the heater can shut off when used at altitudes above 7,000 feet, which might be a limitation for users in high-altitude regions.

Additionally, due to recent changes, some models no longer include a fan, which might affect heat distribution for those versions.
