Why is my Raypak 206A Gas Heater turning on and off repeatedly?
- M
  melissabrownAug 22, 2025
  If your Raypak Gas Heater is going on and off continuously, the issue could stem from a few different causes. The filter might be dirty, requiring a cleaning or replacement. The water level in your pool might be too low, so try raising it. The external bypass setting may be out of adjustment, requiring an adjustment. Lastly, the pressure switch could be out of adjustment, and you should adjust it.

Why does my Raypak Gas Heater have a yellow lazy flame?
- J
  Joseph HuntAug 25, 2025
  If your Raypak Gas Heater is producing a yellow, lazy flame, it could be due to low gas pressure, in which case you should adjust the gas pressure. Another potential cause is insects or debris clogging the burner intake ports; if this is the case, clean the burners.

What to do if the combustion fan is not running on my Raypak 206A Gas Heater?
- K
  Katherine SchroederAug 26, 2025
  If the combustion fan in your Raypak Gas Heater is not running, it could be due to several reasons. The fan relay might be faulty, so replace it. There might be a loose connection or a failed motor in the fan itself. A burned motor due to incorrect wiring could also be the cause, so replace the blower. Finally, the air pressure switch might need replacement.

What to do if my Raypak 206A Gas Heater takes too long to heat pool or spa?
- D
  Destiny SandovalAug 27, 2025
  If your Raypak Gas Heater is taking too long to heat your pool or spa, consider these potential causes: * The heater might be undersized. Calculate the heating capacity of the heater using the formula: Heater output (BTUH) = Pool gallonage x 8.33, or refer to the heater sizing chart. * The filter might not be running long enough; reset the time clock. * The filter could be dirty; clean the filter. * The gas line or meter may be undersized; refer to the installation instructions.

Why does my Raypak 206A Gas Heater take so long to heat my pool or spa?
- E
  Emily WaltonAug 29, 2025
  If your Raypak Gas Heater takes too long to heat your pool or spa, several factors could be at play. It may be that the heater is undersized. You can calculate the heating capacity of your heater using the formula: Heater output (BTUH) / (Pool gallonage x 8.33), or refer to the heater sizing chart. Remember that this calculation doesn't account for heat loss due to weather. The filter may not be running long enough, so try resetting the time clock. A dirty filter could also be the culprit, so try cleaning it. Finally, the gas line or meter might be undersized.

What causes sooting in my Raypak Gas Heater?
- H
  hintonlaurenAug 30, 2025
  If your Raypak Gas Heater is sooting, it could be due to several reasons. High flow rates might be the cause; reduce them by adding a manual bypass valve and adjust it until the heater outlet water temperature is between 105°F and 110°F. The U.G. might be inoperative; check its movement by putting it in hot water (110°F or higher), and replace it if there's no movement. Air starvation could be the issue. Improper venting could also cause sooting. Insects or debris clogging the burner intake ports can also lead to sooting; clean the burners in this case.

What to do if the outer jacket of my Raypak 206A Gas Heater is very hot and the paint is blistered?
- D
  deckeradrianAug 31, 2025
  If the outer jacket of your Raypak Gas Heater is very hot and the paint is blistered, it could be due to a broken refractory caused by shipping damage or improper combustion, in which case you should replace the refractory panels. Another cause could be excessive sooting of the heat exchanger; determine the cause of sooting and correct it.

What causes a pilot outage or weak flame signal in my Raypak 206A?
- E
  Erin WilsonSep 1, 2025
  If you're experiencing a pilot outage or a weak flame signal in your Raypak Gas Heater, it could be due to low gas pressure, so adjust the gas pressure. It could also be due to a restricted or dirty pilot, so clean the pilot and/or electrode. Alternatively, the pilot generator might be weak, in which case you should replace the pilot.

How to fix harmonics or whining noise coming from my Raypak Gas Heater?
- D
  Darren CohenSep 2, 2025
  If your Raypak Gas Heater is producing harmonics or a whining noise, it could be due to several reasons. The U.G. might be inoperative; check its movement by putting it in hot water (110°F or higher), and replace it if there's no movement. There might be debris or a restriction in the system; locate the restriction and remove it, then flush and clean the system. Debris in the gas line could also be the cause; remove the debris or blow out the gas line. Low flow could also be the problem; scale may be forming in the heat exchanger, so clean the heat exchanger and check the pool's pH and total alkalinity.
