Question: where is the gas fitting on the heater back or bottom
Document: We purchased this unit because in the winter time the bathroom is SOOOOOOOOOOO cold! With the recommendation of our propane company we purchase this unit. When I ordered this unit found that I selected the wrong type of gas unit when it was getting installed, contacted the company and they were SOOOOOOOOOOOO wonderful like the unit, replaced it with no questions asked! Shipped out the correct unit to get it here in time for the installers to install and then shipped back the wrong unit.
About the only minor dings I would give are these:1. The screw-on attachment point for the gas is on the bottom of the unit, so if you wanted to set it on the floor, you will have to place it on some type of stand (mine is on Bricks) - obviously, you should make certain everything around the unit is fire-proof :)2.
I'm using this heater in a two-car garage which is insulated on the side walls. The back wall adjoins our house. Without the heater on, the garage stays at about 45-50 degrees when the outside temp is in the mid-20s. Turning on the heater at the low setting will bring the garage temp up to about 60 in less than two hours.
I love my new Kozy World heater. I put it in my vent-less fire place. It sits perfectly in the space and it warms up one half of my 1800 sq. ft. house. The entire back of the house is kozy. I plan to purchase another heater and put it in the front of my house soon!I highly recommend this heater to anyone who wants to replace their flame heater. There are no fumes like the flame heaters.Love it!!!!!! !
This heater i better then I thought .So far so good .I'M waiting for the first gas bill to see how much it help .
The Kozy Wall Heater is easy to install and easy to operate. Plus the infrared feature in my opinion is more efficient and uses less gas then the regular flame type heater which I believe the gas control mechanism is more prone to breaking down. Thumbs up it's a very good product.
I installed it myself. I already had a natural-gas supply outside the lanai on the patio (for the grill). I drilled through the concrete block wall to provide the gas to connect to the heater. I mounted the heater and connected it with a kit from Lowe's. I don't have a video, but could show some nice stills, except this review format doesn't allow. :(
Recently purchased a Vent Free Natural Gas Infrared Wall Heater. After a google search, the price offered on Amazon was below that of the Home Depot vendor. My order made it to me in 1 day, and I was truly grateful for that as I was under a time crunch to have the heater installed. More than happy with the product, shipment timeliness, and customer service. Thanks so much.
An EXCELLENT &#34;Natural Gas&#34; HEATER. VERY EFFICIENT! I LOVE the Settings,  the Ceramic Elements provide RADIANT HEAT IN ADDITION to I believe its called Convection heat. a GOOD BY PRODUCT of the Reaction is WATER, therefore this HEATER is ALSO a HUMIDIFIER. I previously Owned a Procom Heater that was LARGER, but IT wasn't as EFFECIENT as THIS ONE, which is about a 3rd Smaller. Easy to Mount, and Ignite.
I love this I installed it in the basement of my 100 year old house and it is warm enough to heat my back porch. The only thing I wish I would have gotting was the same one with the thermostat. It still works great for the huge space I am heating.
Answer: yes
