Requirements for Electric Heat Units
SEH_ Units (460–575V)
☐ Verify that the power supply complies with the electric
heater specifications on the unit and heater nameplate.
☐ Inspect the heater junction box and control panel;
tighten any loose connections.
☐ Check electric heat circuits for continuity.
SEH_ Units with 200V or 230V Electric Heat: (Requires
Separate Power Supply to Heater)

Requirements for Gas Heat Units

☐ Gas supply line properly sized and connected to the
unit gas train.
☐ All gas piping joints properly sealed.
☐ Drip leg installed in the gas piping near the unit.
☐ Gas piping leak checked with a soap solution. If piping
connections to the unit are complete, do not pressurize
piping in excess of 0.50 psig or 14" W.C. to prevent
component failure.
☐ Main supply gas pressure adequate.
☐ Flue Tubes clear of any obstructions.
☐ Factory-supplied flue assembly installed on the unit.
☐ Connect the 3/4" CPVC furnace drain stub-out to a
proper condensate drain.
