If the pump isn't working, there could be several reasons: * There's no power: Check the circuit breakers and power source. * The pump is defective: It may need replacement. * It's incorrectly wired: Recheck the wiring. * The time clock settings aren't synchronized: Check the time clock setting.
What to do if my Jandy LXi igniter lights but main burners will not come on?
If the igniter lights but the main burners don't come on, here are some things to check: * Gas valve position: Ensure the gas valve is in the “on” position. * Air in the gas line: Cycle the ignition sequence until the air is purged from the gas line. * Gas valve failure: The gas valve may need to be replaced. * No power to gas valve: Check the controls for proper operation. * Low gas pressure: Check both the supply pressure and the manifold pressure. * High burner throat pressure: Check the burner throat pressure.
What to do if my Jandy LXi Swimming Pool Heater flame lifts and goes out?
If the flame lifts and goes out, it could be due to: * Lean fuel/air mixture - Low supply pressure: Correct the supply pressure to ensure a manifold pressure of 2.5" W.C. (Natural) or 9.0" W.C. (Propane) when firing. * Lean fuel/air mixture - Too much combustion air: Check the burner throat pressure and adjust it to 1.0" W.C.
What causes a short yellow streaked flame in my Jandy LXi?
A short, yellow-streaked flame can be caused by: * Rich fuel/air mixture - High manifold pressure: Correct the manifold pressure to 2.5" W.C. (Natural) or 9.0" W.C. (Propane). * Rich fuel/air mixture - Too little combustion air: Locate and correct any combustion system sealing issues beneath the burners (see Section 10.3). Also, check the burner throat pressure and adjust it to 1.0" W.C.
Why is my Jandy Swimming Pool Heater flame lazy with a yellow tip?
A lazy flame with a yellow tip could be due to wrong gas. Make sure the gas supply matches the gas indicated on the rating plate.
Why is my Jandy Swimming Pool Heater not producing enough heat?
If your heater isn't providing enough heat, consider these possibilities: * Inadequate gas supply: The gas meter or the gas line from the meter to the heater might be too small. * Low manifold gas pressure: The gas pressure on the heater manifold should be adjusted to 2.5" W.C. (Natural) or 9.0" W.C. (Propane). * Heater size inadequate: You might need to replace it with a heater that has a higher input. * Temperature rise set incorrectly: Adjust the temperature rise according to Section 7.8 of this manual.
Why does my Jandy Swimming Pool Heater have a flashback on start-up?
Flashback during start-up can occur due to: * Wrong gas: Verify that the gas supply matches the type indicated on the rating plate. * Burner damage: The burner may need to be replaced.
Why is my Jandy LXi making a pounding or knocking noise?
A pounding or knocking sound may be related to water flow. Check the temperature rise according to Section 7.8 of this manual. If the temperature rise is too high, check the pipe size and pump capacity. Also, inspect for any obstructions or closed valves in the system, and check for a damaged internal bypass or an incorrectly set external bypass.
Why is my Jandy Swimming Pool Heater condensing?
Heater condensing can be attributed to: * Low water temperature: Flue product moisture will condense at start-up until the heater water temperature reaches normal operating conditions. * Heater plumbed backwards: Correct the plumbing.
