SOLUTION
Check movement by putting in hot water (110°F (43.3°C) or
higher).
If no movement, replace.
Locate the restriction and remove. Flush system and clean.
Remove debris or blow out gas line.
Scale forming in heat exchanger - clean heat exchanger and
check pool pH and total alkalinity.
Clean or replace filter.
Raise water level.
Adjust bypass.
Adjust pressure switch.
See Water Chemistry on page 5.
Inspect bypass for movement, if no movement, replace.
Replace if no movement when heated.
Reduce by adding manual bypass valve.
Adjust manual bypass valve until heater outlet water
temperature is between 105°F and 110°F (40.5°C and 43.3°C).
Check movement by putting in hot water (110°F (43.3°C) or
higher).
If no movement, replace.
Refer to installation instructions.
Follow recommended installation instructions.
Clean burners.
Adjust gas pressure.
Clean pilot and/or electrode.
Replace pilot.
Adjust gas pressure.
Clean burners.
Replace refractory panels.
Determine cause of sooting & correct.
Calculate heating capacity of heater:
Htr. output(BTUH)
Pool gallonage x 8.33 or refer to heater sizing chart.
This does not take into account heat loss due to weather.
Reset time clock.
Clean filter.
Refer to installation instructions.
Replace well and maintain proper water chemistry.
Replace heat exchanger and maintain proper water chemistry.
See Pressure Switch Adjustment.
Replace refractory.
Determine cause of sooting and correct.
