Troubleshooting - G&F Manufacturing Gulfstream Owner's Installation & Operations Manual

TROUBLESHOOTING

A simple test to verify that your heater is functioning is to place your hand
above the unit. There should be cool air blowing out the top after time
delay has expired. The return water to the pool should be a few degrees
warmer than water entering the heater. After about 15 minutes of run
time, there should be water draining out of the base of the unit.
If you have reason to believe your heater is not functioning properly, follow
the troubleshooting guide below or call the factory for service.
