Electrical Ratings:
System Transformer: 40 VA minimum NEMA-rated trans-
former. Control systems using SV9601, SV9602, or
other large secondary loads may require a larger
transformer. Refer to the appliance manufacturer rec-
ommendation.
Voltage and Frequency: 24 Vac, 50/60 Hz.
Current draw at 24 Vac: 24V Hot: 1.25A nominal (1.5A
maximum) when igniter is powered.
24V Thermostat: See Table 4.
Electronic Fan Timer Output: 0.1A maximum at 24 Vac.
Output is 8 Vac less than thermostat input voltage at
0.1A draw.
Table 4. Thermostat Current (Run Mode).
Ignition Sequence Timing at 60 Hz
Input
Prepurge Time (Factory-set on SV9402, SV9502, and
SV9602):
15 or 30 seconds depending on model.
Trial for Ignition:
90 seconds.
Automatic Reset Time:
5 minutes.
NOTE:
The SV9403 and SV9503 are lockout models
and do not provide Automatic Reset Time.
Flame Failure Response Time:
1.6 seconds maximum at 3 mA.
IMPORTANT
All timings increase by 20 percent with 50 Hz
input.
Gas Conversion Kits:
See Table 5 for gas conversion kit information.
NOTE:
See appliance manufacturer specifications and
instructions and information in these installa-
tion instructions before attempting to convert
an appliance.
Pipe Adapters:
Angle and straight flange adapters available for 3/8-,
1/2- and 3/4-in. NPT pipe. See Table 6.
NOTE:
Models with 3/4 in. inlet or outlet do not accom-
modate the adapter kits.
