Product Description

APPLICATION

The Q624A is a solid state spark generator (transformer) for use on commercial or industrial gas burners.

FEATURES
• Ignites gas pilots with spark gaps up to 1/4 inch (6 millimeters) in length.
• 15,000 volts peak voltage for reliable lightoff.
• Prevents detection of the ignition spark when properly applied in a flame detection system with the C7027,C7035, or C7044 Minipeeper® or C7061 Dynamic Self-Check Ultraviolet Flame Detector.
• Ignition spark and ultraviolet detector are synchronized by the alternating current supply voltage; spark occurs on one half of the ac cycle and detector operates on the opposite half cycle.
• Recommended for interrupted ignition applications only.
• Mounts in the same space used by conventional ignition transformer.
• Q624 mounting holes are the same as standard transformers; no adapter plate needed.
• Impervious to humidity up to 95 percent relative humidity.
• Weighs 3 pounds (1.4 kilograms) versus 8-1/2 pounds (3.9 kilograms) for standard transformers.

INSTALLATION

When Installing This Product…

1. Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition.

2. Check the ratings given in the instructions and on the product to make sure the product is suitable for your application.

3. Installer must be a trained, experienced, flame safeguard control technician.

4. After installation is complete, check out product operation as provided in these instructions.
 

Mounting

The Q624A mounts in the same space required by a standard ignition transformer, using the same mounting holes. It may be mounted in any position.

1. Loosen the cover screw (FIg. 1) and remove the cover.
2. Insert two leads (NEC CLass 1) through the 1/2 in. (13 mm) conduit knockout (Fig. 1) and connect them to the screw terminals on the terminal board, and to the

terminal strip or wiring subbase of the flame safeguard control (see Table 2 and Fig. 3 or 4).
3. Replace the cover and tighten the cover screw.

4. Connect the high voltage electrode (Fig. 1) to the ignition electrode on the pilot burner, using the appropriate Ignition Cable Assembly or Ignition Cable (see Accessories in the Specifications section).
 

IMPORTANT

The ignition cable should not exceed 15 feet (4.6 meters) in length.

To ground the Q624 to the burner assembly:

1. Use a No. 16 or No. 18 wire.

2. Attach one end of the wire to the Q624 ignition transformer end (GND).

3. Wrap the wire around the igniter (high tension) lead as shown in Fig. 3. Four or five wraps are sufficient.

4. Connect the other end of the wire to the burner assembly (GND).
