F299720 – MHVFB20LPT VENT FREE BLUE FLAME PROPANE HEATER 

20,000 BTU Vent‑Free Blue Flame Propane Heater

Product Description

The F299720 (Model MHVFB20LPT) is a 20,000 BTU vent‑free blue flame liquid propane heater designed to provide efficient, even convection heat for indoor spaces. Using clean‑burning blue flame technology, this heater warms the air in the room by creating natural convection currents—similar to the feel of a traditional furnace.

Perfect for homes, cabins, garages, workshops, sunrooms, and emergency backup heat, this unit requires no electricity, allowing continued heating during power outages. The built‑in electronic spark ignition ensures quick and reliable startup, while the integrated thermostat maintains consistent room temperature automatically.

Installation is flexible: the heater can be wall‑mounted or used free‑standing with the included legs and mounting hardware. Safety is a priority, with a factory‑installed Oxygen Depletion Sensor (ODS) and automatic shutoff system ensuring safe indoor operation.
