Water Supply
Connect the cold water inlet supply
Note: Use white Teflon tape at all threaded water connections
- The cold water inlet joint is ½” NPT threaded pipe.
- The water inlet should be connected by using flexible heavy duty tubing or rigid 
PVC pipe.  If you choose flexible tubing, you will need a ½” threaded male to ½” 
hose barb adapter.  Tubing should be secured with properly sized hose clamps.  
Rigid pipe should be ½” male threads.  Teflon tape should be employed with any 
threaded fittings.
- The inner diameter of the inlet pipe (including the valve) should not be less than 
3/8”.  Larger diameter pipe is acceptable with the appropriate adapters to reduce to 
½” at the inlet joint.
- The  cold  water  valve  must  be  installed inline with  the  water  inlet  pipe.
-  Always  flush  a  new  unit  with  water  to  clear  out  any  collected  deposits  or 
debrisprior to installation.  The supplied screen filter must be correctly installed in 
the  cold  water  inlet  to  prevent  mineral deposits  from your  water  supply  from 
building up in the unit's water valve assembly.  After flushing with cold water and 
confirming that there is no residue in the pipe, install the rubber gasket and tighten 
the water inlet joint.

Mounting Your Water Heater
a)When possible, your water heater should be mounted directly to studs. There 
should be a screw in every available mounting location on the heater.  If studs are 
not available, do NOT hang unit directly from sheetrock without utilizing expansion 
screws.
b) When utilizing expansion screws for sheetrock mounting, hold the unit on the 
wall  where  you  want  it  mounted.  Mark  with  a  pencil  the  (4)  mounting  holes.   
Remove the unit from the wall, and drill 3/8” holes on each mark. (See drawings 
below).
The water heater must not be 
exposed to strong wind.
