Installation / Operation Instruction Manual

Gas Connections continued-

3. While checking for leaks care must be taken to prevent solution from

contacting the electrical connections at the control. If electrical connections

at the control become wet, they must be thoroughly dried before attempting

to operate the water heater.

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 ft (1.9 m) of the water 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 switch and junction box cover.

CAUTION

The water heater and individual shutoff valve must be disconnected

from the gas supply piping system during any pressure testing of the

system at test pressures in excess of 1/2 psi (3.5 kPa). The water

heater must be isolated from the gas supply piping system by closing its

manual shutoff valve during any pressure testing of the gas supply

system at test pressures equal to or less than 1/2 psi (3.5 kPa). The

supply line must be capped when not connected to the water heater.

CAUTION

Turn OFF or disconnect the electrical power supply to the water heater

before servicing. Label all wires prior to disconnection when servicing

controls. Wiring errors can cause improper and dangerous operation.

Verify proper operation after servicing.
