Safety Checks, Repair and Replacements

FENWAL-SERIES 05-14

Fan and Heater

2.With the gas supply shut off, apply electri- cal power to the system by closing the control switch or by advancing the thermo- stat.

3.Check to insure that sparking occurs at the electrode tiops and across the 1/8" gap during the "trail-for-ignition" period speci- fied for the unit. (See Specifications.)

4.05-142 thermostate reset models will lock- out after the "trial-for-ignition" period and a few seconds later will trip the circuit breaker.

5.Manually open the gas supply line and either cycle the thermostat or depress the

manual reset button to recycle the unit.

6.Check that ignition has been accomplished within "trial-for-ignition" period. Sparking will cease immediately after ignition.

7.If system ignites but fails to hold-in, check input voltage and polarity and check to assure that L2 line is grounded. If system ignites but drops-out and input voltage is correct, check level of flame current (5mi- cro Amps minimum). check burner for proper ground.

Safety Checks

An annual imspection and test, conducted prior to the start of the heating season by qualified gas service personnel, is required to verify that the automatic gas ignition system, all associated components (i.e., fand limit switchs), and the appliance combustion cham- ber components operate according to the manufacturer's specifications. Components that have been physically damaged or that otherwise to per- form their function according to specifications must be replaced immediately to avoid creating fire, explosive, and/or toxic hazards that can result inproperty damage, personal injury or even death. Test the control as follows:

1.Manually shut off the gas supply and apply power to the control board. After the "trial-for-ignition" period has elapsed, check that there is no voltage output between terminals B(V1) and V2, using a suitable voltmeter or neon tester.

2.Manually open the gas supply line and re- activate control unit. Sparking should occur and immediately cease when the flame is established. While running, manually close the gas supply. Sparking should promptly reappear when the flame is extinguished. The spark should remain on for the "trial-for-ignition" period and the lock-out. Check that there is no voltage output betweeen terminals B(V1) and V2 described in section 1 above.

NOTE: Recyle system before each test by cycling the thermostate or depressing the manual reset button.

Warnings

1.The Fenwal 05-14 ignition system is not field repairable. Any alteration or modifi cation may result in fire, explosion, toxic hazards, proerty damage, personal injury or death. Consult you local Fenway Authorized Heating Wholesaler for replacement ignition system.

2.Use caution to avoid miswiring a replace ment controller. It is recommended to remove one wire at a time from the defective unit and reconnect it tot the corresponding terminal of the new con

trol. Misconnection can result in condi tions hazardous to life and property.

3.The Fenwal 05-14 Direct Spark Ignition System is desinged for use only on new productrs by manufacturers of gas fired equipment. It may be used only as such, or as a replacement for an existing Fenwal Spark Ignition with the same catalog number. Any substitution or applications must be expressly approved by Fjenwal or the manufacturer of the equipemnt. Improper substitutions or aapplications may result in malfunction of equipemnt such as loss of flame sensing safety circuit creating an explosive atmosphere.
