AUGSMIAR 110-326 Natural Gas Water Heater Thermostat Instruction Manual

Introduction

This manual provides instructions for the safe installation, operation, and maintenance of the AUGSMIAR 110-326 Natural Gas Water Heater Thermostat. This unit is designed for use with natural gas water heaters and includes a replacement thermocouple. Please read this manual thoroughly before installation or use.

Important Safety Information

• Gas appliances require professional installation and service. Improper installation, adjustment, alteration, service, or maintenance can cause property damage, personal injury, or loss of life.
• Always shut off the gas supply to the water heater before performing any installation or maintenance.
• Ensure proper ventilation during installation and operation to prevent carbon monoxide buildup.
• This unit has a built-in non-circulating energy shut-off (ECO) system that shuts off all gas to the water heater in the event of excessive water temperature. If the ECO system activates, the controller will not function and must be replaced. This is a safety feature and not a repairable condition.
• When replacing a non-regulated control, a functioning in-line regulator must be present to control gas pressure to the control.
• Refer to local codes and regulations for gas appliance installation and safety.

Installation Instructions

Warning: Installation of gas water heater components should only be performed by qualified professionals. Incorrect installation can lead to gas leaks, fire, explosion, or carbon monoxide poisoning.

Before You Begin:

• Ensure the main gas supply to the water heater is completely shut off.
• Turn off the water supply to the water heater.
• Drain the water heater tank completely.
• Have appropriate tools ready, including wrenches, pipe sealant suitable for gas lines, and leak detection solution (soapy water).

Installation Steps:

1. Remove Old Thermostat: Carefully disconnect the gas lines, thermocouple, and pilot tube from the old thermostat. Unscrew and remove the old thermostat from the water heater tank.
2. Prepare New Thermostat: Apply appropriate pipe sealant to the threads of the new AUGSMIAR 110-326 thermostat where it connects to the gas lines.
3. Install New Thermostat: Screw the new thermostat into the water heater tank. Ensure it is securely tightened.
4. Connect Gas Lines: Reconnect the main gas supply line, pilot tube, and thermocouple lead to the corresponding ports on the new thermostat. Ensure all connections are tight.
5. Check for Leaks: Slowly turn on the main gas supply. Apply a leak detection solution (soapy water) to all gas connections. Bubbles indicate a leak. If leaks are found, shut off the gas immediately and tighten connections until no bubbles appear.
6. Refill Water Heater: Turn on the water supply and allow the water heater to fill completely before attempting to light the pilot.

Operating the Water Heater Thermostat

Lighting the Pilot:

1. Ensure the gas supply is on and the water heater tank is full.
2. Turn the temperature control knob to the lowest setting (e.g., "Warm" or "Pilot").
3. Press and hold the pilot button (usually red).
4. While holding the pilot button, use an igniter or match to light the pilot flame.
5. Continue holding the pilot button for approximately 30-60 seconds after the pilot lights to allow the thermocouple to heat up and hold the pilot flame.
6. Release the pilot button. If the pilot flame extinguishes, repeat the process.

Adjusting Water Temperature:

Once the pilot is lit, turn the temperature control knob to your desired setting. Settings typically range from "Warm" to "Very Hot." Exercise caution with higher settings to prevent scalding.

Maintenance

Regular maintenance helps ensure efficient and safe operation of your water heater thermostat.

• Annual Inspection: Have a qualified technician inspect your water heater and thermostat annually.
• Check for Leaks: Periodically check all gas connections for leaks using a soapy water solution.
• Thermocouple Check: Ensure the thermocouple is clean and properly positioned in the pilot flame. A dirty or improperly positioned thermocouple can cause the pilot to go out.
• ECO System: Remember that if the ECO system activates due to overheating, the thermostat must be replaced. This is a safety feature and not a repairable condition.

Troubleshooting Common Issues

This section provides guidance for common issues. For complex problems or if you are unsure, contact a qualified professional.

Pilot Light Will Not Stay Lit:

• Insufficient Holding Time: Ensure you hold the pilot button long enough (30-60 seconds) for the thermocouple to heat up.
• Faulty Thermocouple: The thermocouple may be dirty, bent, or defective. Clean or replace it. The included thermocouple may be used as a replacement.
• Gas Supply Issue: Check if the main gas supply is fully open.
• Drafts: Strong drafts can extinguish the pilot. Ensure the area around the water heater is free from excessive airflow.

No Hot Water or Insufficient Hot Water:

• Pilot Light Out: Check if the pilot light is lit. Relight if necessary.
• Thermostat Setting: Ensure the temperature control knob is set to a desired temperature.
• ECO System Activation: If the water heater overheated, the ECO system may have activated, requiring thermostat replacement.
• Gas Supply: Verify the gas supply to the water heater is on.

Gas Odor:

• IMMEDIATE ACTION: If you smell gas, do not operate any electrical switches, light matches, or use phones. Evacuate the premises immediately and call your gas provider or emergency services from a safe location.
• Minor Leak: If a very faint odor is detected and confirmed to be a minor leak at a connection point, shut off the gas supply and tighten the connection. Re-check with leak detection solution. If the leak persists, contact a professional.
