**WARNING: working with gas can be dangerous.  If you are not familiar with local 
building codes and basic gas plumbing practices please employ a professional to 
install your water heater**
1- Securely mount your water heater to the wall in an appropriate location using the 
supplied hardware.
2- Install the venting (4” for 5L or 10L units, 5” for 16L units) per local building codes 
and the instructions supplied.
3- Connect the gas lines (all connections are ½”).   Use yellow Teflon tape at 
threaded  connections.    Check carefully  for  gas leaks  using  soapy  water and 
correct as necessary before proceeding further.
4- Connect the water lines (all connections are ½”).  Use ½” or ¾” pipe or tubing for 
the water supply and return.  If water pressure or flow rates are questionable use 
¾” lines to ensure maximum flow.   You MUST use copper, CPVC or appliance 
tubing intended for use in hot water applications for all hot water lines.
5- Check for and correct water leaks as necessary.
6- Install the batteries in the battery compartment.   Be sure the polarity of the 
batteries is correct.
7- Turn on the faucet and adjust the water and gas settings on the water heater as 
needed for your specific environment and comfort.  **USE CAUTION NOT TO GET 
SCALDED WHILE ADJUSTING YOUR SETTINGS**  Remember that more water 
flow will usually result in less heating, and vice versa.  Higher gas settings result in 
more heating, and vice versa.
8- Begin enjoying instant, energy efficient hot water for years to come!
