Why is there flame roll-out at start-up with my Zodiac Swimming Pool Heater?
Flame roll-out at start-up in your Zodiac Swimming Pool Heater can occur due to: * A blocked flue. Clear the blockage. * A pilot out of position. Correct the pilot position. * A blocked heat exchanger. Clean and correct as necessary. * A refractory blanket out of place. Clean and correct the blanket as necessary. * An altered vent cap. Install an unaltered factory approved vent cap. * Low gas pressure. Check and correct the gas pressure.
What causes pilot outage in Zodiac Legacy LRZ?
Pilot outage in your Zodiac Swimming Pool Heater can be caused by several factors: * **Low Inlet Gas Pressure:** Consult your gas utility company. Ensure the inlet gas pressure to the heater is within the range of 13.7 to 24.9 mbar for natural gas or 24.9 to 34.8 mbar for propane gas. * **High Inlet Gas Pressure:** Pressure should be regulated within the specified limits. * **Weak or Defective Thermocouple/Thermopile:** Replace the thermocouple or thermopile. * **Damaged Pilot Components:** Replace any damaged pilot, thermocouple, or thermopile. * **Dirty Pilot:** Blow dust or lint out of the pilot. * **Plugged or Undersized Pilot Orifice:** Clean or replace the pilot orifice. * **Plugged Burner Orifices:** Remove and clean all burner orifices.
Why is there spillage at draft hood of my Zodiac Legacy LRZ Swimming Pool Heater?
Spillage at the draft hood of your Zodiac Swimming Pool Heater can happen because of: * A cold chimney. Allow the heater to run for five minutes to establish draft action. * A vent pipe that slopes downward toward the chimney. Reinstall the vent pipe so it slopes upwards from the heater to the chimney. * A blocked chimney. Clear the blockage. * An altered draft hood. Install a factory-provided draft hood. * A prefabricated chimney with an incorrect cap. Install a U.L. listed vent cap.
Why is my Zodiac Legacy LRZ Swimming Pool Heater not producing enough heat?
If your Zodiac Swimming Pool Heater isn't producing enough heat, consider the following: * **Inadequate Gas Supply:** The gas meter or the gas line from the meter to the heater might be too small. * **Low Burner Gas Pressure:** Adjust the gas pressure on the heater burner to the values listed in Table 2. * **Inadequate Heater Size:** You may need to replace the heater with one that has a higher input. * **Low Temperature Rise:** Check and correct the water flow.
What causes lazy flame with yellow tip in Zodiac Legacy LRZ?
A lazy flame with a yellow tip in your Zodiac Swimming Pool Heater could be due to: * Low primary air. Check for internal burner obstructions. * Incorrect burner pressure. Adjust burner pressure according to the rating plate and clean burner ports if they are dirty.
Why is my Zodiac Legacy LRZ Swimming Pool Heater pounding or knocking?
Heater pounding or knocking in your Zodiac Swimming Pool Heater can be caused by inadequate water flow through the heater. Check the temperature rise between the inlet and outlet heater piping. If the temperature rise is above the recommended maximum (see section 11.6), check for a closed valve in the system.
Why is my Zodiac Legacy LRZ condensing?
Condensation in your Zodiac Swimming Pool Heater is often due to low water temperature. Flue product moisture will condense at start-up until the heater water reaches normal operating temperature.
What to do if pressure relief valve opens on my Zodiac Legacy LRZ?
If the pressure relief valve on your Zodiac Swimming Pool Heater opens, it could indicate a restriction in the water flow system at or downstream of the heater. Check the operation of all valves, the bypass valve, and any equipment between the pool and the heater outlet.
