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 the unit. Connect the COLD WATER line to the water heater marked COLD WATER IN on the right side when facing the
unit. DO NOT USE TEFLON TAPE OR PASTE on fittings.
Step 3 After tightening both fittings at the water heater, open several hot water faucets and allow water to run through 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.
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 electric codes.
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 could 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.
