7.  MAINTENANCE

The following preventative maintenance is to be 

performed one month after start-up and semi-annually 

thereafter.

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  operation.  See 

"De-sooting Procedure" on page 26.

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 

illustrated  in  the  Post  Start-Up  Inspection  section. 

Yellow flame means restriction of the air openings. 

Lifting or blowing flame indicates high gas pressure. 

Low  flame  means  low  gas  pressure.  Should  these 

occur,  shut  the  heater  off  and  contact  your  gas 

supplier or qualified service agency.

5.  On  indoor  heaters,  clean  room  intake  openings  to 

ensure adequate flow of combustion and ventilation 

air.

6.  Keep  area  around  heater  clear  and  free  from 

combustible materials, gasoline and other flammable 

and corrosive vapors and liquids.

7.1.  Service

Verify proper operation after servicing.
S’assurer  que  l’appareil  fonctionne  adéquatement  une 

fois l’entretien terminé.

7.1.1.  Water Pressure Switch

The  water  pressure  switch,  ensures  that  the  heater 

operates  only  when  the  filter  pump  is  in  operation.  It 

is located on the In/Out header. It is factory set at 1.75 

PSI (12kPa) for deck-level installations. When the heater 

is  located  below  the  level  of  the  spa  or  pool,  it  may  be 

necessary to adjust the pressure switch to compensate 

for the no-flow static head. If it is necessary to adjust the 

water pressure switch, utilize the following procedure.

A

A

CAUTION:

 Do not adjust the pressure switch until all 

air has been evacuated from the system and the water 

flow rate meets the requirements listed in Table I.

Water Pressure Switch Adjustment

1.  With  pump  and  heater  on,  turn  adjustment  knob 

clockwise until a click is heard from the gas valve.

2.  Turn adjustment knob counter-clockwise 1/4 turn.

3.  Turn pump off and on several times. Heater should 

shut off immediately. If it does not, repeat the above 

steps.

NOTE:

 If heater is installed outside of the limits shown, a 

higher pressure rated 11 psi (76 kPa) switch may be used. 

A flow switch, mounted and wired adjacent to the heater, 

may be used in place of the factory mounted pressure 

switch. See Illustrated Parts List for 11 psi (76 kPa)  water 

pressure switch.

7.1.2.  Two-Speed Pumps

In some cases, the flow on the low-speed is insufficient 

to  operate  the  heater.  This  is  apparent  when  the  water 

pressure switch cannot be further adjusted or if the heater 

makes banging noises or shuts off on high limit. In these 

cases, the pump must be run at high speed when heating 

the water.

A

A

CAUTION:

 Do not operate the heater without the 

function of a properly adjusted water pressure switch or 

flow switch. 

7.1.3.  Pilot Safety

The heater employs a pilot safety which closes the main 

gas valve within 8/10ths of a second whenever the pilot 

flame  is  interrupted.  The  pilot  flame  is  automatically  lit 

when the device is powered. The heater performs its own 

safety check and opens the main valve only after the pilot 

is proven to be lit.
