CAUTION
The water heater and an individual shut-off 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 shut-off 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.
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.
Turn off the water heater gas valve and disconnect power to the water heater.
If wiring in conduit is required, cut the flexible line cord at least 6 in. (15.2 cm)
from the bushing. Unscrew the damper, flip it over, and pull the cord into the
damper housing. Cut the three wires from the line cord at the bushing inside
of the housing. Drill a hole to receive the 1/2” electrical conduit connector on
the side of the damper. Wire the power supply into the circuit at the
appropriate locations.
Set the damper right side up and screw it do the jacket head as it was
previously mounted. Re-connect the damper wire harness to the damper.
Connect power to the water heater and turn the water heater gas valve back
on.
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.
Route the damper power cord to eliminate any trip hazards and prevent any
cutting and abrasion.
WARNING
Do not position the damper power cord where it can be cut or severed. The
damper power cord’s position must be consistent with 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.
