37E73A-903 & 906 INTELLI-VENT™

Water Heater Thermostat Control

Installation Instructions

For Natural Gas Only

Operator: Save these instructions for future use!

FAILURETO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.

DESCRIPTION

The 37E73A-903/906 INTELLI-IGNITION™ control is a combination gas valve, ignition control, and thermostat for use on Power Vented water heaters. The microcomputer in the control supervises the ignition sequence and timings for the water heater, and provides diagnostic codes in case of system malfunction. The control provides direct burner ignition using the White-Rodgers’ Silicon Nitride ignitor. The control uses the INTELLI-IGNITION™ technology to greatly extend the ignitor’s life.

Fixed Adjustment Regulator Controls: The gas regulator on this control requires no field service. The regulator automatically controls and maintains the burner gas pressure.

!WARNING

“WHAT TO DO IF YOU SMELL GAS”

Do not try to light any appliance.

Do not touch any electrical switch; do not use any phone in your building.

Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s Instructions.

If you cannot reach your gas supplier, call the fire department.

!WARNING

Do not use this Natural Gas control on LP Gas water heater. Improper operation could occur, resulting in personal injury and/or death due to Carbon Monoxide (CO) poisoning, fire, or explosion. Check for proper gas type as listed on the rating plate affixed to the water heater.
