    Me Heat

    Nice product, in respects to acquiring parts not included. Basically you will need to purchase a brass fitting 3/8'NPTx 1/2 or 3/8 JIC 90 degree & gas line. Also unit comes with a electronic igniter for the pilot,

    Would buy again

    I was very reluctant to buy a ventless gas heater after reading Heats my entire first floor very quickly and save heating cost. since it releases water vapor as by product, it helps with the northeast dry air.

    Works great in our living room.

    Easy to control flame to regulate heat output. it's much better if you need natural gas or propane.
