Qsan -23 R3 Wiring Instructions

24 VOLT DIRECT SPARK IGNITION
HIGH-INTENSITY GAS-FIRED INFRARED HEATERS
The intent of these instructions is to help the EXPERIENCED, QUALIFIED INSTALLER OR SERVICE AGENCY for the
electrical installation and operation of this type of gas-fired equipment. These instructions may not cover all details or
variations in this equipment, or cover every possible situation to be met in connection with the installation/operation.
Should problems arise not covered sufficiently in these instructions, the purchaser is advised to contact the Engineering
Department (1-800-223-5335 ext.117) for further information.
maintenance can cause property damage, injury or death.
manufacturer's instruction manual BEFORE installing, servicing, or operating this heater.
ALL WIRING MUST COMPLY WITH THE LATEST
EDITION OF THE NATIONAL ELECTRICAL CODE
AND ALL OTHER
REGULATIONS, AND ORDINANCES
SPECIFICATIONS:
•
Natural or LP/propane gas.
•
100% safety shut-off.
•
24V. electrical operation.
•
Direct spark ignition.
•
No pilot burner.
ARRANGEMENT:
•
Solenoid gas valve.
•
Spark electrode and flame sensor.
•
Ignition detection control.
SEQUENCE OF OPERATION:
1. Thermostat calls for heat.
2. Power is applied to the 35-602 ignition detection
control (IDC). 15 seconds after power is applied,
spark develops at electrodes & main gas valve
opens.
3. Burner ignites; electrical current begins flowing
from sensing electrode through flame to ground.
4. IDC senses current, turns OFF spark, gas
continues to flow through the main gas valve.
5. On flame outage at sensing electrode, the IDC
responds and begins sparking within 0.8 seconds.
A 15-second trial-for-ignition period begins to re-
light the burner. If flame is re-established, normal
operation resumes. If the burner does not light after
the first try, the inter-purge sequence is completed
between trials to re-light the burner. If the burner
fails to light after third trial, the IDC will de-energize
the main gas valve and go into lockout mode.
6. Should burner fail to light or flame is not detected
during first trial-for-ignition period, the main gas
valve is de-energized and the IDC starts the 15-
second inter-purge sequence before another
ignition trial. After 15 seconds, the IDC begins 2
more ignition trials. If these trials fail, the IDC goes
into lockout mode.
7. For lockout recovery, reset the thermostat below
ambient temperature or disconnect electrical power
supply for 5 seconds.
LIGHTING INSTRUCTIONS:
1. Set main gas valve to OFF position.
2. Turn electrical supply OFF.
3. Wait at least five (5) minutes.
4. Set thermostat above room temperature.
5. Set main gas valve to ON position.
6. Turn electrical supply ON.
7. Set thermostat at desired temperature.
8. If heater does not light, repeat steps 1 – 7.

FIELD WIRING INSTRUCTIONS
1. 24V. – 60HZ. – 1PH.; 2 wire incoming service required.
2. Connect incoming blue wire to heaters' blue wire (wire nut
supplied by others).
3. Connect incoming green wire to heater's green ground screw.
(Ring terminal supplied by others).
4. This control system can not determine the presence of flame
if it is not grounded to the burner. It will lockout and shut off.
Proper grounding and polarity are essential to its' operation.
