contacting the electrical connections at the control. If electrical connections at
the control become wet, they must be thoroughly dried before attempting to

Electrical Connections
All electrical wiring and connections must be in accordance with the
National Electric Code ANSI/NFPA No. 70 (latest edition), or the Canadian
Electrical Code C22.1 (latest edition) and any local codes which may
apply. The water heater must be electrically grounded.
If a flexible line cord and plug is permitted by local code, then provide a (3)
three wire grounding type receptacle within 6 feet (1.9 m) of the w ater
heater and use the flexible cord provided. Do not plug the line cord into a
receptacle that can have its power supply interrupted by a switch that is
used to turn on and off lights.
If wiring in conduit is required, cut the flexible line cord flush with the
bushing. Remove the junction box cover and pull the pressure switch
outside of the junction box. Cut the three wires from the line cord at the
bushing inside of the junction box. Drill a hole to receive the 1/2’’ electrical
conduit connector on the backside of the blower. Wire the power supply
into the circuit at the appropriate locations. Replace the pressure sw itch
and junction box cover.
CAUTION
Turn off or disconnect the electrical power supply to the water
heater before servicing. Label all w ires prior to disconnection when
servicing controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing.
