BGH2UNCNTRLHT-01 Universal

Hot Surface Ignition Control

Application

The BASO Gas Products BGH2UNCNTRLHT-01

Universal Series Hot Surface Ignition (HSI) control is

microprocessor based with timed ignition and suited

for replacement or new applications. Applications for

hot surface ignition modules include agricultural

equipment, space heaters, furnaces,

residential/commercial boilers, water heaters, pool

and spa heaters, and a variety of other commercial

cooking equipment.

This control includes a 5 position DIP switch allowing

up to 32 programmable pre-defined timing selections

to retrofit other Hot Surface Ignitions with flame

sensing rectification, such as: Johnson Controls,

Honeywell, White Rodgers, Fenwal, and

Robertshaw.

The BGH2UNCNTRLHT-01 works with single-rod or

dual-rod sensing to prove a flame. The control has a

continuous and precise monitoring of the HSI

element, wiring, and gas valve, shutting down in the

event of a failure. For a complete listing of

specifications, refer to the Technical Specifications

section.

Installation

IMPORTANT: Only qualified personnel

should install or service BASO Gas Products®.

These instructions are a guide for such personnel.

Carefully follow all instructions for the appliance.

IMPORTANT: Make all gas installations in

accordance with applicable local, national, and

regional regulations.

WARNING: Risk of Explosion or Fire.

Do not install the control in an area that is exposed

to water (for example, dripping, spraying, rain). Do

not use the control if it has been exposed to water.

Exposure to water may cause malfunction and can

lead to an explosion or fire and may result in

severe personal injury or death.

Replacing the Existing Ignition Control 7. Mount the new control with #6 sheet metal or machine screws through the mounting holes in the enclosure. 8. Refer to the Wiring section for electrical connections and wiring diagrams. Perform the Checkout section before leaving the installation. 9. Check all wiring for proper connections and make sure your system is properly grounded. ! CAUTION: Risk of Electric Shock. Disconnect power supply before making electrical connections to avoid electric shock.

Setup and Adjustments Select Dip Switch Positions A 5 position dip switch is provided on the controller to allow for field programming of 1 to 32 possible predefined sets of timing sequences. Select a predefined timing sequence from Table 1 and then set the dip switches on the control. To change the settings, remove power from the circuit board, change settings and re-apply power to the circuit board.

Checkout ! WARNING: Risk of Explosion or Fire. Verify that there are no gas leaks by testing with appropriate equipment. Never use a match or lighter to test for the presence of gas. Failure to test properly can lead to an explosion or fire and may result in severe personal injury or death. Make sure all components function properly by performing the following checks. 1. Before starting the appliance, perform a safety inspection of piping, burners and venting. Check for gas leaks, etc.

• 100% Shutoff (Flame Not Sensed) With 3 Ignition Trials (Bad Flame/No Flame): If the control does not prove the presence of igniter flame within the “Trial-For-Ignition” time, then the relay gas valve is turned “OFF” (deenergized) and the control initiates a time delay of “Between-Trial-Purge” time, and then followed by another ignition sequence. If flame is not sensed, an ignition sequence is repeated until the total number of Trials-for-Ignition are completed.

Troubleshooting ! WARNING: Risk of Personal Injury. Do not place face, hands, or other parts of the body in or near the burner area when the LED is flashing (recycle mode). When the LED is flashing, the control may at any time (while in the recycle mode) re-energize the burner control system and ignite the burner which may result in electric shock from contact with the electrode or severe burn injury from firing of the burner.

Turn on power and gas. Close thermostat contacts. Module LED did not light? 24V between No 24V and 24V(GND) terminals? Yes Module LED blinks green? Check transformer, thermostat and wiring. Repair or replace as needed. Yes No No Replace module. LED blinks 1, 3, or 5 quick red flashes, then pause? Yes No LED blinks 2 quick red flashes, then pause? Yes Replace module.

Maintenance Requirements in Severe Environments Regular preventive maintenance is important in any application, but especially so in commercial cooking, agricultural, and industrial applications because: • In many such applications, particularly commercial cooking, the equipment operates 100,000 to 200,000 cycles per year. Such heavy cycling can wear out the gas control in one to two years.
