controller circuit board where the black wire with a
yellow trace is connected (test point 14). A reading of
less than 20 V here indicates a faulty controller. If the
reading is more than 20 V, turn the rotary switch to
"OFF" and then "POOL" or "SPA" again to be sure
that the internal contacts are working correctly. The
voltmeter reading should drop to zero when the switch
is "OFF" and return to at least 20 V when the switch is
placed back in the "POOL" or "SPA" position.
10.4.7 Gas Valve
The gas valve consists of an internal operating
valve and a regulator. The valve supplies gas to the
main burners for heater operation. The regulator
allows limited adjustment of the manifold pressure.
The gas valve will operate only when there is a
call for heat, all safety circuits have been satisfied and
after the igniter has been energized. If the gas valve
does not operate under these conditions, check the
voltage going to the gas valve. Leave the red voltmeter
lead at the common terminal of the transformer (test
point 1). Move the black meter lead to the "valve"
terminal on the ignition control where the brown wire
from the gas valve is connected (test point 20). If the
voltage is not within the range of 20 -28 VAC, check
that the igniter is energized and glowing. (There is a 40
second heat up time between the initial energizing of
the igniter and the activation of the gas valve). If the
igniter is energized, the 40 second heat up time has
passed and the meter does not show 20-28 VAC, then
the ignition control is faulty and will need to be re-
placed. If 20-28 V is shown at test point 20 move the
black lead of the meter to the terminal on the gas valve
where the brown wire is connected (test point 21).
This test point will have voltage present only during a
trial for ignition or during normal operation. The meter
should read 20-28 Volts. If there is no voltage, then
there is a bad connection between the gas valve and
the controller. Replace the brown wire.
Listen closely to the gas valve when it is first
activated (24V first appears at test point 21 during the
trial for ignition). There should an audible "click" when
the valve opens.
If there is voltage at test point 21, but the gas
valve does not open, replace the valve.
10.4.8 Igniter/Ignition Control Circuit
WARNING
The igniter, power supply circuit board and some
terminals of the ignition control utilize 115V or 230V
power and require appropriate servicing precautions.
Note that wires and terminals of these components
may be "hot" even when the component is not
operating.
AVERTISSEMENT
Le dispositif d'allumage, le circuit d'alimentation
électrique et certaines bornes de la commande
d'allumage utilisent une tension de 120 V ou de 220
V et exigent des précautions appropriées lors du
service d'entretien et de réparation. Notez que les fils
et les bornes de ces composants peuvent être
chauds même si le composant ne fonctionne pas.
Check the resistance of the igniter. Disconnect
the hot surface igniter form the ignition control and the
red wire that leads to the power supply terminal strip.
Set your meter to read in the range of 0-100 ohms.
Place one lead of the meter in the connector at the end
of each of the igniter wires (test points H and I). The
resistance should read between 40 and 75 Ohms at
ambient air temperature. If the meter reads outside of
this range or shows an open or short circuit, replace
the igniter.
Check the voltage supplied to the igniter. Set
your voltmeter to read in a range to up to 120 VAC.
Place one lead of the meter in the connector on the
end of the red wire coming from the power supply
terminal strip (test point J). If the heater is supplied
with 115 VAC, place the other meter lead on the
"IGN/120" terminal (test point K) on the ignition
control. The meter should read between 98 and 126
VAC. If the heater is supplied with 230 VAC, place
the other meter lead on the "IGN/240" terminal (test
point L) on the ignition control. The meter should read
between 98 and 126 VAC if read with a RMS meter
or 50-65 VAC if read with a non RMS meter. If the
meter shows voltages outside of the corresponding
range, either the ignition control or the red wire
connected to the power supply terminal strip is faulty.
Check the red wire, its connections and termi-
nals. If the wire is sound, replace the ignition control.
