Electrical Connections - Honeywell 51370B Manal

Gas Connections continued-
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.
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 feet (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.
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.
