If you are mechanically minded, the short answer is yes. The Genesis II comes as a single modular unit. The basic steps are:
- Mount the unit using the 4 bolt holes on the unit itself.
- Attach hot and cold water outlets.
- Mount the on\off switch.
- Vent the exhaust and combustion air inlet.
- Connect the power to the unit.
It would be up to you to design where the fuel tank will go and how the electrical is connected. Also, please use a qualified plumber and electrician when and where required.
