If your Lochinvar Water Heater is producing water that is too hot, it may be due to: * The thermostat being set too high. Adjust the temperature knob to a lower setting. * A defective gas control valve/thermostat. Replace the gas control valve/thermostat.
Why is my Lochinvar Water Heater not producing enough hot water?
To address insufficient hot water in your Lochinvar Water Heater, consider the following: * Check with your gas utility company to ensure adequate gas pressure. * Replace the orifice with the correct size (refer to the rating plate). * Adjust the thermostat to a higher temperature setting. * Refer to the gas control error codes for troubleshooting. * Drain and flush the tank to remove sediment or lime; consider water treatment. * Ensure the water heater is adequately sized for your needs. * Verify correct piping connections, ensuring the dip tube is in the cold inlet. * Repair any leaking faucets. * Address wasted hot water issues. * Insulate long runs of exposed piping and hot-water piping in outside walls.
What to do if my Lochinvar POWER VENTED GAS HEATERS burner won't light?
If you are unable to light the burner on your Lochinvar Water Heater, it could be due to: * Air in the gas line. Purge the air from the gas line. * A faulty pressure switch. Check the pressure switch and ensure the hose is not kinked. * A blocked exhaust. Inspect the vent pipe for any blockages. * Wiring issues. Check all wire connections. * A defective gas control valve/thermostat. Replace the gas control valve/thermostat.
Why is the hot surface igniter not glowing on my Lochinvar Water Heater?
If the hot surface igniter on your Lochinvar Water Heater is not glowing after the warm-up period, the possible causes are: * Reversed polarity at the 120VAC outlet receptacle. Reverse the polarity. * A defective hot surface igniter. Replace the igniter. * A defective gas control valve/thermostat. Replace the gas control valve/thermostat.
How to fix a Lochinvar Water Heater with a burner flame that is too high?
If your Lochinvar Water Heater burner flame is too high, the possible causes include blocked air inlets, insufficient secondary air, or an incorrectly sized orifice. Try these solutions: * Unblock the inlet air openings. * Ensure adequate ventilation to the water heater. * Replace the orifice with the correct size.
What to do if the blower on my Lochinvar Water Heater runs continuously?
If the blower on your Lochinvar water heater runs continuously, it could be due to several reasons: * The air pressure switch may not be closing due to insufficient draft caused by a blocked vent, excessive piping length, or a clogged blower. Remove any blockages, reduce vent length or increase vent size, and clean the blower wheel. * The pressure switch hose from the air pressure switch to the blower housing may be disconnected, torn, or blocked. Reconnect or replace the hose. * The pressure switch may be defective and require replacement. * The high limit switch may be open due to excessive vent temperature or a defective switch. Determine the cause of overheating by checking for overfiring, insufficient air supply, or high ambient air temperature.
Why does my Lochinvar POWER VENTED GAS HEATERS smell like combustion?
If you notice combustion odors from your Lochinvar Water Heater, it could be due to: * Blocked air inlets (unblock them). * Insufficient air (provide fresh air ventilation). * A clogged flue (clean it, locate the source, and correct). * The heater being installed in a confined area (provide fresh air ventilation). * A house that is too tight (provide fresh air ventilation).
Why is my Lochinvar POWER VENTED GAS HEATERS Water Heater taking so long to heat water?
If your Lochinvar Water Heater is experiencing slow hot water recovery, possible causes include: * Insufficient air or flue blockage. Provide ventilation and check the flue way, flue baffle, and burner. * Low gas pressure. Check with your gas utility company. * Orifice too small. Replace with the correct orifice (see rating plate). * Thermostat set too low. Turn the temperature knob to a higher setting. * Heater too small. Install an adequate heater. * Wrong piping connection. Correct the piping, ensuring the dip tube is in the cold inlet. * Wasted hot water. Advise the customer on water conservation. * Flue clogged. Clean the flue, locate the source, and correct. * Air inlets blocked. Unblock the inlet air openings.
Why is my Lochinvar POWER VENTED GAS HEATERS smoking and forming carbon?
If you observe smoking and carbon formation with your Lochinvar Water Heater, the causes may include: * Blocked air inlets: Unblock the inlet air openings. * Insufficient air: Provide ventilation and check the flue way, flue baffle, and burner. * Low gas pressure: Check with your gas utility company. * Orifice too large: Replace with the correct orifice (see rating plate). * Clogged flue: Clean, locate the source, and correct. * Defective gas control valve/thermostat: Replace the gas control valve/thermostat. * Heater installed in a confined area: Provide fresh air ventilation.
Why is my Lochinvar POWER VENTED GAS HEATERS Water Heater relief valve dripping?
If you experience a drip from the relief valve on your Lochinvar Water Heater, it could be due to: * Pressure build-up. Use a pressure-reducing valve and relief valve. * Heater stacking. Lower the thermostat setting. * A closed water system. See the thermal expansion section. * An improperly seated valve. Check the relief valve for proper operation (Do Not plug T&P valve).
