24VAC Side-Mount Igniter and Open Flame Burner

(with QuickConnect Gas Light Igniter Plug-in Receptacle Kit with 7/8"nut)

The KnightLighter™ igniter with the solenoid valve mounted on the side of the igniter box is designed to be installed in the bottom of the gaslight head. It should fit almost on the floor of the gaslight so as to be inconspicuous.

24VAC IGNITER/OPEN FLAME BURNER INSTALLATION

IN GLM 1200 OR EQUIVALENT

Upgrading and new installation procedures for installing the 24VAC igniter in the MHP VK-7A or GLM 1200 Open Flame burner gaslights or equivalent post, wall, or pier mount gaslights. (Start at instruction 7 for installations in new gaslight heads.)

1. Turn off the gas to the gaslight at the source going to the gaslight so that the gaslight with its manual valve can be removed.

2. Remove the glass from the gaslight.

3. Loosen the screws that hold the gaslight on the pier/post and raise the gaslight to allow disconnecting the manual valve from the copper tubing.

4. Remove the burner from the manual valve and save the burner and chimney.

5. Remove the manual valve.

6. Clean and repair the gaslight if necessary.

Start here for installation in new gaslight head:

7. The quick-connect fitting with modified manual shut-off valve shall be pre-assembled (See Figure 1) before installing in the light. NOTE: Apply TFE Paste thread sealer to each connection if not already applied.

Figure 1

8. Install the quick-connect fitting by inserting into the pre-existing access hole in the base of the gaslight. (See Figure 2). Attach and tighten the 7/8” valve nut.

Figure 2

9. Drill access holes for the 24VAC input line (on the bottom of the gas light head); drill a hole for the Daylight Sensor in either of the two locations shown. Make sure the daylight sensor is not pointed toward any bright lights (street lights, Holiday lights, etc.) The daylight sensor must have a clear view of daylight for the lamp to shut off during the day. (See Figure 3)

Figure 3

10. Install the previously prepared Igniter/Open Flame Burner (See Figure 4) in the gaslight by snapping the unit into the quick connect fitting.

Figure 4

11. Reinstall the gaslight on the post or pier; apply TFE Paste thread sealer and connect the 1/4" copper gas line by tightening the 1/4" Flare Nut onto the input to the gaslight valve. If using another type of valve, attach a 1/4" x 1/8" Flare fitting if necessary. Push the copper tubing down into the post (for post installations).

12. Align the igniter and insert the daylight sensor (photo sensor on yellow and black twisted wires) into the access hole that was drilled in step 9. Be sure that the daylight sensor does not view the lamp flame or reflections off the glass.

13. The back of the daylight sensor is also sensitive to light; cover it sheath or with black electrical tape so the lamp does not shine on the back side of the plastic sensor.

14. Check the alignment of the lamp sensor; verify that it is pointed up toward the position of the flame.

15. Apply sheath to lamp sensor (Optional).

16. Check the alignment of the ignition probe. The igniter/burner is a single unit with an open wire probe leading from the high voltage transformer to the probe gap at the side of the open flame. The probe shall be aligned crosswise of the slit and be positioned just within the gas/air boundary of the flame coming out of the side of the burner slit. The gap shall be about 3/16 inch. (See photos below.) No ceramic insulator or bracket is required. This arrangement has the added advantage that soot will not build up on the probe.

17. Check the gas line for leaks using bubble water solution or a gas detector around the fittings. If any leaks are present, correct them before powering the igniter.

18. Use small wire nuts to connect the 24VAC power wires to the input power wires on the KnightLighter Igniter. The input wires on the 24VAC igniter are not polarized or color coded.

NOTE: NEVER CONNECT 120 VAC DIRECTLY TO THE IGNITER. The 24VAC igniter will not withstand 120 VAC. A transformer must be used to convert 120VAC to 24VAC.

19. Replace the mantles.

20. Replace the glass in the gaslight.

21. Turn on the gas.

This completes the installation of the automatic gaslight.

Quick Checkout of the Automatic gaslight:

1. Cover the lamp sensor and the daylight sensor with black tape or otherwise to simulate darkness. Turn on power to igniter.

2. Sparks shall appear across the spark probe to the pilot burner ring and the solenoid valve shall open. The gaslight shall light. Remove the tape from the flame sensor and the gaslight shall remain lit.

3. Remove the tape from the daylight sensor and the lamp shall go out in about 30 seconds. Replace the glass panels.

4. This completes the gaslight checkout. It is ready to operate.

Normal Operation of the KnightLighter Igniter in the Gaslight.

1. To operate the igniter, connect power from 24VAC to the igniter input power wires.

2. Cover both photo sensors with black tape to simulate dark conditions. The solenoid valve shall enable and sparks shall occur across a 3/16 +/- 1/32 inch gap, from high voltage probe to the burner/chassis return.

Note: Keep photo sensor leads separated from the high voltage lead. If not, the photo-sensor leads may pick up Electro Magnetic Interference (EMI) from the sparking and reset the microcontroller prematurely. (It will not give a complete set of 10 spark bursts). Any direct sparks to the photo-sensors will damage the sensor/microprocessor.

With gas connected to the lamp and 24VAC connected to the power leads of the igniter, the following sparking sequence shall occur:

|Condition |Result |

|1. Both sensors sense dark. |Sparking starts and solenoid valve turns ON. (Sparks up to ten 2-second bursts of |

| |sparks in about 45 seconds) |

|1a. If lamp lights and lamp sensor detects flame |Lamp stays ON and the sparking stops. |

|1b. If lamp does not light* |Spark bursts continue for 10 cycles and then stop. Solenoid valve turns OFF and the |

| |ignition cycle stops. |

|2. Wait 50-60 seconds to purge gas. |Sparking starts and solenoid valve turns ON. (Sparks up to ten 2-second bursts of |

| |sparks in about 45 seconds) |

|2a. If lamp lights and lamp sensor detects flame |Lamp stays ON and the sparking stops. |

|2b. If lamp does not light* |Spark bursts continue for 10 cycles and then stop. Solenoid valve turns OFF and the |

| |ignition cycle stops. |

|3. Wait 50-60 seconds to purge gas. |Sparking starts and solenoid valve turns ON. (Sparks up to ten 2-second bursts of |

| |sparks in about 45 seconds) |

|3a. If lamp lights and lamp sensor detects flame |Lamp stays ON and the sparking stops. |

|3b. If lamp does not light* |Solenoid valve turns OFF and the ignition cycle stops until the next evening or until|

| |the power is cycled. The igniter is reset when the daylight sensor detects light or |

| |when power is recycled. |

|4. When daylight sensor detects morning daylight |Lamp continues to burn for about 5 minutes and then shuts down for the day. The delay|

| |is to prevent the lamp from turning off when car lights may trigger the daylight |

| |sensor at night. |

*Since both sensors are covered with black tape, the flame will not stay lit and the igniter will continue with ignition sequence. To test the flame sensor’s ability to sense light, the tape should be removed from flame sensor as soon as lamp lights.

Electrical Reset

The igniter is reset if the electrical power is turned OFF and back ON. This can be done by switching the electrical power OFF and ON. The above ignition cycles will be initiated with a power reset and both sensors detecting darkness.

Gaslight Testing

1. The gaslight igniter can also be cycled at night by shining a flashlight on the daylight sensor for a few seconds and then removing the light. The igniter thinks it was a very short day.

2. To test the gaslight during the day, both sensors must be shielded from light by covering with black electrical tape or another method. (A black pen cap works on the lamp sensor.) Fingers alone may not be adequate to block the light as infra-red light goes through the fingers or hand. Since both sensors are covered with black tape, the flame will not stay lit and the igniter will continue with ignition sequence. To test the flame sensor’s ability to sense light, the tape should be removed from flame sensor as soon as lamp lights.

NOTE: The most common problem with the automatic igniter is probe adjustment in the gas-flame stream. Ignition works best if the probe is on the boundary of the flame, so that the spark crosses the gas/air boundary. The electronic igniter itself is very reliable and rugged.
