I.  MOUNTING THE UNIT

1) The unit should be mounted as close to the point of use as possible.

Do not install the heater above a faucet or “point of use” because the siphoning effect may  
drain the heater which can cause premature element burn out.

2) This unit must only be mounted in a vertical position with the 

water fittings located at the

bottom of the unit

. Mounting other than in the vertical position 

WILL

cause element burn 

out and cause permanent damage to the water heater.

3) The cold water inlet is on the right hand side and the hot water outlet is on the left hand side.

Under 

NO

circumstances can these be reversed.

4) Leave a minimum of 8” above the unit for easy replacement of the element.

5) The heater should be fixed to the wall using all four mounting holes of the backplate.  Unit 

weight is approximately 15 lbs.  Use an appropriate fastener for this weight.  For the unit to
be mounted against hollow walls, suggest using steel wall anchors, with the correct grip
range and #6-32 screw size minimum.

NOTE: The heater should be installed below the level of all hot water outlets serviced by this

heater.

NOTE: PRESSURE AND TEMPERATURE RELIEF VALVE

These units are not required by UL to have a Pressure and Temperature Relief
Valve (PTRV). You should check with local codes to find out if one is required in your
area.  If local codes require the use of a temperature and pressure relief valve it
should be installed on the outlet hot water pipe before the outlet ball valve.
