SECTION 3 - MAINTENANCE AND CARE PROCEDURES
To be followed one month after
1.Inspect top of heater and drafthood for soot, a sticky black substance around finned tubes and "V" baffles, and open flue gas passageways. Any visible soot should be cleaned for proper opera- tion.
CAUTION: Soot may be combustible. Wet sooted surfaces completely prior to cleaning. Do not use steel wire brush.
2.Clean main burners and pilot burner of dust and lint.
3.Inspect and operate all controls, gas valve and pressure relief valve (if equipped).
4.Make visual check of the burner and pilot flames. Flame pattern on the main burner and pilot is illus- trated on page 7. Yellow flame means restriction of the air openings. Lifting or blowing flame indi- cates high gas pressure. Low flame means low gas pressure. Should the latter occur, shut the heater off and contact your gas supplier or quali- fied service agency.
5.On indoor heaters, clean room intake openings to ensure adequate flow of combustion and ventila- tion air.
CAUTION: Combustion air must not be contaminat- ed by corrosive chemical fumes which can damage the heater and void the warranty.
6.Keep area around heater clear and free from com- bustible materials, gasoline and other flammable and corrosive vapors and liquids.
IF HEATER WILL NOT FIRE:
If you have no electrical power, it may be that your "circuit breaker" has tripped. Try
If you have electrical power but the heater will not fire check the following or see Troubleshooting section:
1.The time clock must be in the "ON" position.
2.Your pump strainer basket may be full. If so remove debris.
3.Your filter may be dirty. If so, backwash or clean filter. (To tell if your filter is dirty, look to see if the filter pressure will be higher than usual).
4.The pump may have lost its prime and be running dry. Check the pressure on the filter. If there is no pressure; then you are not moving water (or your gauge is broken). Try to get the pump to run at its normal flow rate.
POOL & SPA WATER CHEMISTRY
Chemical imbalance can cause severe damage to your heater and associated equipment. Maintain your water chemistry according to the chart on page 2. If the mineral content and dissolved solids in the water become too high, scale forms inside the heat exchang- er tubes, reducing heater efficiency and damaging the heater. If the pH drops below 7.2, this will cause cor- rosion of the heat exchanger and severely damage the heater. Heat exchanger damage resulting from chem- ical imbalance is not covered by the warranty.
AUTOMATIC CHLORINATORS AND
CHEMICAL FEEDERS
All chemicals must be introduced and completely dilut- ed into the pool or spa water before being circulated through the heater. Do not place sanitizing chemicals in the skimmer. High chemical concentrations will result when the pump is not running (e.g. overnight).
Chlorinators must feed downstream of the heater and have an
See plumbing diagram page 21.
NOTE: High chemical concentrates from feeders and chlorinators that are out of adjustment will cause rapid corrosion to the heat exchanger. Such damage is not covered under the warranty.
