Unit won't operate and there are 4 flashes on the red light.

Two things- Clean the sensor rods or replace(cheap and easy with YouTube instruction video) and at the same time replace the main program chip (also a easy plug in chip). The whole repair takes two hours for a homeowner and costs about 50 bucks for a chip. These are easy an generally the flame sensor rod is the culprit. The code may also be the limit switch but try EZ and cheap first. See You Tube.. https://www.youtube.com/watch?v=npxcVo7RK2c

I went to take a shower this morning and the water was ice cold. For more than twenty minutes the water ran and never warmed up. Are there common things to check my hot water heater for in this situ

There is an adjustment knob to control how hot the water can become. There might be a problem at the tap (however, if this is the case, you would still get hot water everywhere in the house). If the entire house isn't getting hot water, and the knob is set at the hottest water, you probably need to get the hot water tank replaced.

Can i convert a Rheem ECO 180DVP (LP gas unit) to a natural gas unit ?

Rheem water heaters should not be converted from propane to natural gas. The burners have been optimized for the rated gas and will not work as well after conversion. (Unlike ranges where the gas/air flow ratios can be adjusted when the burner orifices and regulator are swapped, the water heater doesn't have that option.) I wish I had better news for you. I recommend you get a new water heater for the LNG service; it will be safer and more efficient. Cindy Wells

Why wont the pilot light on my hot water tank stay lit

there is no pilot- it is lit with a ignitor. If you have problems the unit needs a service cleaning of the flame sensor rods.

Does a installation maqnual come with purchase of ecoh160dvln tankless water heater

The installation is according to your local code. They will tell you what outlets and where to have them- what water piping and what gas requirements. You will need a flush valve set( always extra) Your city inspectors will lso control placement and venting requirementrs. This is not a plug and play install although it is straightforeward. You must meet the minimum water pressure and volume as well as the proper gas delivery requirements- even a drain.. Best on this point to hire QUALIFIED INSTALLER.

Will 1 tankless water heater be enough for a whole house?

It can be. I have a 7.4 GPM for my whole house, and it is way more than I need. It will handle 3 simultaneous uses no problem. Check with a dealer or literature on those units available in your area. They should give you some guidance.
