Time Clock/Fireman's Switch
To operate the heater with a time clock, connect the
timer to the fireman's switch connection in the heater's
wiring. The time clock should be of the dual switch
type and set to shut off the call for heat to the pool
heater (chauffe-piscine) 15 to 20 minutes prior to shut-
ting down the pool pump. On analog heaters, splice
into the red/white wire to connect the time clock. For
digital heaters the fireman's switch connection is locat-
ed on the 14-pin header connected to the digital
control board. Splice into the red wire jumper tagged
"Where necessary add "Fireman's" switch circuit here"
to connect the time clock. The fireman's switch con-
nection on both analog and digital heaters must be
a dry contact and must not supply power to the
heater. Powering the fireman's switch connection
externally may damage the heater, and is not cov-
ered by warranty.
Digital heaters: Do not exceed 50ft (15.2 m) of total
wiring using 18 AWG stranded copper wire rated for
221°F (105°C) minimum.
NOTE: When using a time clock, the heater will
display "Clock/ Fireman Sw" when the fireman's
switch is open, indicating that the time clock has shut
off the call for heat.

Post Start-Up Inspection

Do not use this heater if any part has been under
water. Immediately call a qualified service technician
to inspect the heater and to replace any part of the
control system and any gas control which has been
under water.
N'utilisez pas cet appareil s'il a ete plonge dans l'eau,
meme partiellement. Faites inspecter l'appareil par un
technicien qualifie et remplacez toute partie du sys-
teme de controle et toute commande qui ont ete
plonges dans l'eau.
WARNING: Should overheating occur or the gas
supply fail to shut off, turn off the manual gas control
to the appliance.
AVERTISSEMENT: En cas de surchauffe ou si
l'alimentation en gaz ne s'arrete pas, fermez
manueiiement ie robinet d'arret de l'admission de

Feel the inlet and outlet pipes. Outlet pipe should be
only slightly warmer than the inlet. It should not be hot.
With the heater on, remove the door and make a visu-
al check of the burner.

Cold Weather Operation

Moderate Climate
Heater operation can continue during short-term cold
spells. When temperatures are between 0° (-17°C)
and 32°F (0°C), flow (continuous pump operation)
must be maintained.
CAUTION: Do not use the heater to maintain water
temperatures just above freezing or for freeze
protection. When heater is 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 (10°C) is not recommended. When starting the
heater with water temperatures below 50°F (10°C),
operate the heater continuously until higher tempera-
tures are reached. Operating the heater for prolonged
periods with pool water below 50°F (10°C) can seri-
ously damage the heater, and is not covered by the
warranty.
For cold climate areas, please follow the winterizing
procedures listed in the next section.
Winterizing the Pool/Spa Heater
(chauffe - piscine)
Heaters installed outdoors in freezing climate areas
may be shut down for the winter. Observe the follow-
ing procedure for winterizing the heater.
