Operating Instructions
3A. General Information
With any new pool or spa installation, and at
spring startup, operate the filter pump with the heater
off long enough to completely clean the water. This will
remove any installation residue from the water. Clean
the filter at the end of this operation before starting the
heater.
Caution
Do not use this heater if any part has been
under water. Immediately call a qualified
service technician to inspect the heater and
replace any part of the control system and any
gas control which has been under water.
Attention
N'utilisez pas cet appareil s'il a été plongé dans
l'eau, même partiellement. Faites inspecter
l'appareil par un technicien qualifié et
remplacez toute partie du système de contrôle
et toute commande qui ont été plongés dans
l'eau.
Caution
Should overheating occur or the gas supply fail
to shut off, turn off the manual gas control valve
to the heater.
Attention
En cas de surchauffe ou si l'alimentation en
gaz ne s'arrête pas, fermez manuellement le
robinet d'arrêt de l'admission de gaz.
Caution
Keep all objects off the top of the heater.
Blocking air flow could damage the heater, and
may void the warranty.
WARNING
For your safety, when starting the heater,stand
away from the front of the heater and keep your
head and face well away from the firebox
opening to prevent any risk of personal injury.
3B. Lighting and Shutdown Procedures
(See page 8)
NOTE: If your LP tank runs out of fuel, turn off
gas at the heater. After the tank is refilled, the
heater must be relit following the instructions
found on the heater. DO NOT attempt repairs on
the gas control or heater. Tampering is danger-
ous and voids all warranties.
3C. Setting the Temperature Control
The temperature control (see Figure 4) is cali-
brated at the factory and covers a range from approxi-
mately 70°F to 104°F (21°C to 40°C). Use an accu-
rate pool thermometer to determine the best water
temperature for your uses.
IMPORTANT: The temperature controls cannot
be calibrated in the field. If the control is faulty, shut
down the heater and have a qualified service technician
replace the control. DO NOT use the thermostat switch
to completely shut down the heater.
3D. Seasonal Care
Caution
Do not operate this heater outdoors at
temperatures below 20 degrees Fahrenheit (°F)
(-7 degrees Celsius [°C]).
3D-1. Spring and Fall Operation
During periods when the pool is only going to be
used occasionally, turn the temperature control down
to the MIN setting. This prevents the pool from water
from becoming chilled, and minimizes the time re-
quired to raise the pool water back up to the desired
temperature.
In areas subject to only short freeze periods, turn
off the heater and run the pump continuously for the
length of the freeze period.
If the heater is not going to be used for a long
period of time, shut it down completely. Follow the
instructions found on the inside of the heater, or page 8
of this manual.
