We have a Friendship and Ray is correct. It is gas and electric.
To run on propane, the electric switch needs to be off and vice versa for running on electric.
FOR PROPANE:
The propane water heater switch is on the wall near the cooktop. Mine is grouped with the levels test switch (battery/propane/holding tanks) and the water pump on/off switch. When you turn the propane water heater switch on, a tiny red light under the switch indicates the pilot is OUT. When the red light goes out the pilot is lit and the burners should come on. If the little red light comes back on, it is indicating the burners did not ignite.
Reminder: the electric water heater switch must be off for the propane water heater to operate.
On occasion, the carbon builds up on the tip of the pilot. It will try to light then the red pilot indicator light comes back on to signify the pilot is out. To clean it I use an emery board that I stole from my wife's fingernail kit.
FOR ELECTRIC:
On mine, the electric water heater switch is on the side of the bar/buffet cabinet. The cabinet is located at the entrance to the hallway as you enter the bath area. The switch is about waist high and is in a surface mounted electric box. The box contains the switch and a small square red indicator light. When the electric water heater switch is on, the red indicator light is lit.
Reminder: the propane water heater switch must be off for the electric water heater to operate.
As Ray said, check to make sure the element has power to it.
