@8Muddypaws Good point.. so here goes…Nobody is going to be able to help you without more information.
what brand of water heater is it?
do any other gas appliances work? Stove, refer, heater?
have you found a manual and done any of troubleshooting?
How did you bleed the lines? If the stove lights it has propane but if it was run completely out it would be normal to have to turn the water heater on, let it try it's 3 times and fail, 2 or 3 times before all air is out and it will stay on to complete heating the water.Bled the lines a few times
I would agree with that. If it is less than a year old they should be willing to help you.Take it a k to the dealer.
