4.Make visual check of the burner and pilot flame. Flame pattern on the main burner and pilot is indicated in the previous illustration. Yellow flame means restriction of the air openings. Lifting or blowing flame indicates high gas pressure. Low flame means low gas pressure. Should this occur, shut the heater off and contact your gas supplier or qualified service agency.

5.On indoor heaters, clean room intake openings to assure adequate flow of combustion and ventilation air.

CAUTION: Combustion air must not be contaminated corrosive chemical fumes which can damage the heater.

6.Keep area around heater clear and free from combustible materials and other flammable and corrosive vapors and liquids.

BASIC TIPS IF HEATER WILL NOT FIRE:

1.If you have no electrical power; it may be your "circuit breakers" have tripped. Try re-setting them.

2.if you have electrical power but the heater will not fire

check the following:

3.The time clock must be moved to the "ON" position.

4.Your pump strainer basket may be full. If so remove debris.

5.your filter may be dirty. If so, backwash or clean filter.

(To tell if your filter is dirty, the gauge pressure will be higher than usual).

6.The pump amy have lost it's prime. It may be running dry, check the pressure gauge 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 it's normal flow rate.

COLD WEATHER OPERATION

MODERATE CLIMATE: Heater operation can con- tinue during short term cold spells. When tempera- tures are below freezing, flow (continuous pump op- eration) must be maintained.

CAUTION: Do not use the heater to maintain water temperatures just above freezing or for freeze protec- tion. When heaters are used during freezing weather care must be taken to avoid freeze ups. Continuous pump operation is a must. Additional protection may be required. The heater is not warranted against freeze ups.

COLD CLIMATE: Prolonged operation with water temperatures below 50°F is not recommended. When starting the heater with pool temperatures below 50°F, operate the heater continuously until higher tempera- tures are reached. Operating the heater for prolonged periods with pool water below 50° can seriously dam- age the heater, and is not covered by the warranty.

For cold climate areas please follow the winterizing procedures listed below.

WINTERIZING THE SPA HEATER

When heaters installed outdoors in freezing cli- mate areas are to be shut down for the winter, observe the following step-by-step procedure:

1.Turn off gas valve, manual gas valve, and electrical supply to the heater.

2.Open drain cock located on the inlet/outlet header, (under water pipes). Remove drain changer inspection panels on the side opposite water piping to gain access to the plug on the return header.

POOL & SPA WATER CHEMISTRY

Chemical imbalance can cause severe damage to

 

 

your heater and associated equipment. Maintain your

 

 

water pH between 7.4 and 7.8 and total alkalinity

 

 

between 100 and 150 p.p.m. If the mineral content and

 

 

dissolved solids in the water become too high, scale

 

 

forms inside the heat exchanger tubes, reducing

 

 

heater efficiency and also damaging the heater. If the

 

 

pH drops below 7.2, the heater will be severely dam-

 

 

aged. This will result in corrosion of the heat ex-
