    • Perfect fit
Size: 6 Gallon Style: Direct Spark Ignition, Incoloy Electric ...
My original Suburban water heater was old (2012) and rust was showing in the faucets when I commissioned the water system in the spring. A LOT of rust. I always winterize properly. I knew it was time and wanted to avert a disaster in the camper. This one fits perfectly. It went right back in and mounted the same way. All the screws matched up. The only thing I had to change was to install a Switch inside the camper for the AC heating option. The old one had the switch mounted to the water heater itself. You had to go outside to turn on the AC heating option. I did not like this and this fixed that. The wiring was easy. It is a 12-volt switch that controls a relay for the AC side heating. There were only 4 wires to connect in total. Just make sure you map out the original wiring as the manufacturer did not match the wire colors on the heater that were wired to the switch in the Galley. The Propane connection was a snap. Very easy. Just know that it takes time for the propane gas to purge the air from the system before it will fire. The pilot light is a very small jet. Be patient and keep trying. This heater will try to fire it 3 times and then stop for safety. Just Turn the propane switch off and try again. It fired on the 5th try for me. I have a propane gas detector to check for leaks. You should too. This does not come with a door or mounting frame. You will have to use the original ones or purchase new ones. If you are handy and good with tools you can do this. ... show more

After 17 years I had to replace because tank was leaking. Wood platform was a mess so I had to build a new one. It was a project which took most of the day. I also had to change the power relay which took some time. Overall, it was a project most would not want to do but slow and steady won the day. Electric and gas worked the first time I turned them on. No need to adjust the flame on gas burner. I called suburban to make sure self installation did not void the warranty. Very satisfied with this product! ... show more

    • Easy direct replacement
Size: Size: Front & Rear Mats Combo Set Style: Direct Spark Ignition & Incoloy Elec...
Installed this one to replace the exact same model that was 16 years old. Installation was very straight forward; just re-installed exactly as the old one came out. Like many other comments I read here, I found the installation instructions are pretty useless. Unit does not come with a door, and I had to buy about $70.00 worth of hardware as the original Tiffin hardware was unusable. I also decided to go with flex water feed lines for easier installation over the PEX which added cost. There was a problem starting the gas initially as it sparked but wouldn't light. I lit the stove to clear air out the line and could easily then smell gas, but still wouldn't light- until the gas flashed in my face. I traced the problem to a Mis installed ignitor that was grounding to the venturi rather than the other ignitor probe. It was easy to re-center it in the venturi and it then fired up immediately. Hope to get many years of use of of it. ... show more

    • Be aware that Suburban's service and warranty policy is terrible.
Size: Size: Front & Rear Mats Combo Set Style: Direct Spark Ignition & Incoloy Elec...
Bought this brand new unit to replace old corroded one. Installed it and the AC heating element works fine. Went to connect the gas side of the heater. The module opened the gas solenoid, but would not operate the piezo lighter. Smell gas, but no click. Yes, temp is below 110 and wiring is correct. Suburban was closed for Labor Day weekend. Bought a replacement module from Amazon. Then, the spark clicker runs until it times out, but won't open the gas solenoid. Nobody could tell me if the module on Amazon is the correct one. Great. Out of curiosity, I pull the old nasty module out of the removed old water heater and everything works fine. Obviously just a bad module. It happens. But for that much money, think I deserve a new module. I wait until after the holiday and call Suburban. I found out that they have absolutely nothing to do with answering questions, service or warranty. All done through local dealers. The head office girl did say that I would have to remove the whole heater and take it to their dealer or they would not warranty it. Seems pretty stupid in this case, but doesn't matter, since the 3 local dealers given to me by Suburban refused to look at it or talk about it since I didn't buy it from them! Is this for real? If Ford or Chevy or Toyota did that, nobody would buy their cars. There are other companies making RV water heaters out there, I suggest you look at one of them. Ridiculous that the manufacturer won't even SELL you a warranty part. Run away. ... show more

As a DIY repair person, I was a bit concerned about replacing the hot water heater in my travel trailer. This model was a perfect fit and easy to connect if you follow the directions. I only got to try it once before Winter set in and now I am anxious to really try it out this Spring on an extended trip. ... show more
