Dyna-Glo wall heaters are the ideal choice for safe indoor supplemental heating. This state-of-the-art vent free technology does not require a flue or chimney. These heaters are great for use in your home, cabin or garage. The heaters make an excellent choice for everyday heating and emergency situations where the power goes out as they do not require electricity to operate. Using blue flame heating technology, heat is distributed similar to your central home heating system. This Blue Flame Wall Heater burns with 99.9% efficiency and operates on Propane only. Not for sale in California. Check your local regulations on installation restrictions and requirements. Propane use requires 100 lbs. tank or larger with two-stage adjustable regulator available from the gas company. DEPENDABLE - Ideal for daily supplemental or emergency use such as power outages. ECONOMICAL - Cut heating bills by warming only occupied areas. COMFORT Heater automatically adjusts to your desired temperature, just like a home thermostat. SAFE - Built-in oxygen depletion sensor immediately shuts down the heater if carbon monoxide or lack of oxygen is detected. CONVENIENT 1 continuous press of the battery assisted igniter makes ignition quick and effortless. VERSATILE - Includes all necessary hardware for wall mounting. UPGRADEABLE - Separately sold optional base legs (WBL100) allow floor mounting. Separately sold optional Wall Heater Fan (WHF100) distributes heat in a quiet, yet powerful way.
