USE ONLY GENUINE REPLACEMENT PARTS 29
LOSS OF FLAME – RECYCLE: If flame is established and then lost, the control will make ten (10) attempts at ignition. If flame is
lost within ten (10) seconds of ignition, the control will respond within 2 seconds. If flame is lost more than ten (10) seconds after
ignition the control will respond within 0.8 seconds.
1. The control de-energizes the gas valve and the blower.
2. The control monitors for open contacts at the blower vacuum switch.
3. The control performs a gas valve relay check.
4. A normal ignition sequence resumes with Item #2 in NORMAL OPERATION FOR POOL & SPA MODES (see above).
5. If the tenth ignition trial fails the control enters a safety lockout (or “hard” lockout) after the post- purge period of the tenth failed
trial.
6. The error code “IF” is displayed and the “SERVICE” indicator is illuminated.
a. The control automatically resets after 60 minutes. If there is a call for heat after reset the control will make three (3) trials
for ignition. If ignition is not established the control will again enter safety lockout for 60 minutes. If flame is established but
is lost the control will make ten (10) attempts at ignition. This cycle will continue until ignition is established or the call for
heat is removed.
b. The user can reset the control and clear the “IF” error code by pressing the “MODE” button to move through “STANDBY”
and return to the previous mode (“POOL” or ”SPA”).
AUTOMATIC RESET TIME: The heater will automatically reset when an error condition is corrected and resume operation as
detailed in NORMAL OPERATION FOR POOL & SPA MODES (see above). The heater can be manually reset using the keypad by
cycling the mode button through “STANDBY” and back to the original operating mode (“SPA” or “POOL”).
GAS TESTING:
GAS LINE TESTING: The appliance and its gas connection must be leak tested before placing the appliance in operation. The
heater must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing
of the gas supply piping system at test pressure equal to or less than ½ psig (3.45 kPa). Gas supply line must be capped when not
connected. After pressure testing, reconnect the gas piping to the gas valve. Turn gas supply “ON” and test all pipe and tubing joints
for leaks. Use a soap and water solution.
WARNING: EXPLOSIVE HAZARD. The use of an open flame to check for gas leaks could cause an explosion
resulting in severe injury and/ or death. Shut off gas and fix even the smallest leak right away. Be sure to leak test
the heater gas manifold fittings using the above procedure once the heater is in operation.
GAS PRESSURE TESTING: The following gas pressure requirements are important for the operation of the burners in gas heaters.
Improper gas pressure or gas volume may create the following conditions:
1. Flame burns totally yellow.
2. Flame lift off burner.
3. Heat exchanger soot’s up. The gas pressure regulator on all heaters is preset at the factory, but the setting should be verified
by the installer to ensure proper operation.
NOTICE: If inlet gas pressure is inadequate, check for undersize piping between the gas meter and the heater or for a low-
capacity gas meter (see GAS SUPPLY section of this manual).
