Question about Daewoo Heating & Cooling
A line or coil freezing is a sign of restricted air flow or low on freon. Make sure the fan that circulates the cold air is working and the filter and coil at the filter are clean. A dirty coil can be cleaned with coil cleaner and a water hose. You will need to remove the unit and take it outside. (window units only) You can buy a bottle of coil cleaner at any hardware store. Follow the instructions on the bottle but basically you spray the coil until soaked wait 5 minutes and flush it clean with water from a hose. Repeat if necessary. Try not to get water and cleaner on the controls. Be careful water will be trapped in the unit you may want to tip it toword the back for 10 minutes or so and if possible let it set outside to dry. Reinstall the unit and put a clean filter on it and give it a try. If ice forms again it is low on freon and will require a repairman to fix it. Freon is a restricted item and you have to have a license to buy it. good luck..

Thank you for posting your question here on Fixya.com.
Is it Natural gas or LP gas?
What pressure does your gas provider supply it with? (It will usually be low pressure, ~14"WC if NG)
How far from the access point you will get gas from to the heater?
Once you have answers for these three questions use the installation guide found on pages 13-14 of this manual to determine the proper gas line size. Be sure if you use a different material pipe, like CSST, you adjust the pipe size based on manufacturer's recommendations. 1" copper and 1" CSST are NOT equivalent!
