What to do if your millivolt pool heater is burning?
When the millivolt power from the Generator reaches the Gas Valve, releasing the Pilot button will allow the gas to continue flowing to the pilot, if the power is sufficient. If you have a strong burning pilot, be sure that the flame is engulfing the Pilot Generator; sometimes they can slip down, away from the flame.
How did the millivolt pool heater get its name?
A millivolt pool heater is one that has a ‘standing-pilot’, burning all the time. It also will not have a digital display panel, usually just an on/off switch and a thermostat dial.

What to do if your swimming pool heater is not working?
Make sure that the pilot is lit (millivolt heaters). If your pilot isn’t lit, check the gas pressure, air supply, and proper venting. Make sure the pilot tube is intact and not clogged.
