    Can this heater be used in a cabin that is not insulated  efficiently above 6000 feet?
    1 Answer
    Vent-free gas heaters struggle to operate consistently above 4,500 feet.   It will work intermittently, but, occasionally, the oxygen depletion sensor will shut the heater down due to the altitude.

    Does this throw much heat out of the front of the heater? The heaters we used as replacements throw the majority of their heat out of the top of the heater.
    1 Answer
    To better distribute the heat, we recommend adding the optional SunStar Space Heater Blower for this heater.

    Where does the propane tank sit?
    1 Answer
    Like any other indoor gas heating system we offer in liquid propane, the tank will need to be located outside the home. For specific guidance, your local LP supplier or a locally-licensed plumber should be contacted.

    from Nevada asked:
    August 8, 2018
    Is it just High, Medium, and Low settings or are there temperature settings such as degrees C/F? And does the thermostat turn the main burner on and off to maintain the temperature all while leaving the pilot light lit at all times?
    1 Answer
    The temperature control is going to be a Hi-Low control as opposed to specific degrees. The thermostat will shut the unit off while keeping the pilot lit, while turning it back on when the temperature drops.

    Does this heater come with a hose, or elbow to connect to the propane tank?
    1 Answer
    This heater will not arrive with any rigid or flexible gas connection as these items should be supplied by a qualified installer (plumber, gas fitter, etc.).

    from Durango, CO asked:
    March 15, 2013
    Can this unit be used at 7000 ft altitude?
    1 Answer
    The manufacturer states that at altitudes above 5,000 feet, shut down of the heater by the ODS system may occur due to reduced oxygen levels above this altitude.

    from Forest Knolls, CA asked:
    September 26, 2012
    Does this need to be hooked up to our propane tank outside or does it have its own propane tank? Is this convection and radiant?
    1 Answer
    This unit could either be hooked to the LP supply tank for your home or can be used independently on a smaller independent cylinder. For prolonged operation, I strongly recommend plumbing the heater to your central LP gas line. This will allow the unit to operate for hours at a time, without loss of BTU capacity. This heater is strictly radiant; however, a blower can be added to convect heat as well. The blower that is compatible for this unit is located in the Accessories section of the item page.

    Overall it's best heater!!!
    The heater works great, it was hard to install the blower that would be a 4 star. Once it was installed everything was working and I love it.
