STEP 1

Bring the HOT WATER and COLD WATER lines to the heater. We recommend that a manual shut -off

valve  (ball  valve)  be  installed  on  the  inlet  and  outlet  of  the  water  heater  so  there  is  a  convenient  shut -off
point  available  in  the  event  that  future  maintenance  or  servicing  is  required.  Before  connecting  these
pipes  to  the water heater hoses if used, it is  extremely  important to  FLUSH the lines to  eliminate all plumbing
paste or residue in the lines caused by any welding or soldering. We recommend using flex water heater hoses
for ease of installation.

STEP 2

Connect the HOT WATER line to the water heater marked HOT WATER OUT located on the left side of the

heater when facing unit. Connect the COLD WATER line to the water heater marked COLD WATER IN on the right
side when facing unit. DO NOT USE TEFLON TAPE OR PASTE on fittings.

ST EP 3

After tightening both fittings at the water heater, open several hot water faucets and allow water

to run though the water heater for at least 2 to 3 minutes. This process purges all the air from the water lines
and MUST be performed prior to turning on the power at the unit. FAILURE TO FOLLOW THIS STEP CAN CAUSE
PERMANENT DAMAGE TO THE HEATING ELEMENTS. When any maintenance is performed on the water heater
or the home’s plumbing system that may introduce air into the plumbing pipes, it is important to turn the power
off to the water heater and purge the air out of the lines before allowing the unit to power up.

STEP 4

Carefully inspect all connections, unions, and the pressure relief valve (if installed) for leaks.

STEP 5

If your water heater is installed on a second floor, heated attic, or other location where water damage

could occur a water pan is recommended.

5- ELECTRICAL INSTALLATION

PLEASE READ THESE INSTRUCTIONS THOROUGHLY AND COMPLETELY BEFORE INSTALLATION AND BEFORE
USE. FAILURE TO DO SO COULD CAUSE PROPERTY DAMAGE, SERIOUS PERSONAL INJURY, DEATH AND
VOID YOUR WARRANTY.

This product

is recommended to be installed by a licensed and qualified electrician

in accordance with all

applicable national, state, provincial, and local electrical codes.

As with all electrical appliances, under no

circumstances should you attempt to install, repair or disassemble this water heater without first shutting off all
power to the unit directly at the fuse or breaker box. SERIOUS BODILY INJURY OR DEATH COULD OCCUR IF YOU
IGNORE THIS WARNING.

All wiring (wire gauge) and circuit protection (breakers) must comply with the U.S. National Electrical Code (NEC)
in the U.S.A., or the Canadian Electrical Code (CEC) in Canada. Failure to do so coul d result in property damage
and / or personal injury, and void your  warranty.  Note: the  Canadian Electrical  Code generally requires that all
supply  wires  and  corresponding  circuit  protection  (breakers)  used  for  domestic  hot  water  heating  and  hydronic
heating  applications  be  sized  to  a  minimum  of  125%  of  the  maximum  current  rating  of  the  heater  (see  model
specifications below for details).
Before installing this product, ensure that the home has sufficient electrical power available to handle the
maximum amperage load of the applicable model.
