"Putting a Damper on Cold Air"

THIS INSTALLATION SHALL BE SUBJECT TO THE APPROVAL OF THE ENFORCING AUTHORITIES

  

 

   Damper profile up to 9” diameter.

 

 

 Damper profile for 10” and over.

 

The Ventilation Air Flue Damper, Series ’HAC - F’, is designed to save energy by stopping the escape of warm air up the chimney vent while the heating appliance is not firing and is interlocked to be open during firing. It shall be securely installed close to the appliance and equal in size to the factory built chimney or vent. This damper is spring loaded and fails-safe-open in the event of power failure. If continuous power is not supplied to the Damper from the appliance transformer, (24Vac) an auxiliary transformer (24Vac) connected to the appliance power source is required. If the safety circuit is not fuse protected, an in-line fuse is required and may be purchased direct from the factory. Use part #3152-001. (See wiring diagram)

For COMMERCIAL installations having other than 24Vac, RELAY ADAPTORS are available to interface this Damper to a 250mVdc - 100Vdc and 120Vac Safety Control System. 

This installation shall be in accordance with: In Canada - can/CSA b149 & b139; In the USA - ANSI/NFPA 54, 2006, ANSI Z223.1 and/or local codes including local codes relating to exhaust vent installation. A qualified contractor shall be consulted regarding the installation of this damper.

 

Specifications:

Motor 24Vac,- 5 Watts, 50/60 Hz. .

Relay Coil 0.05 Amps.

Damper Identification:

e.g.: HAC-06-*4-1-SPC   - F 

 

 

*4 - designates a Belimo actuator, spring return.

 

VENTILATION FLUE AIR CONTROL DAMPERS are designed to have a 10% bypass to allow for a minimum escape of air during the off cycle of firing. Nylon bearings and all wiring are mounted 1" away from the heated part of the damper to prevent the effects of excess heat.

Dampers are designed for years of trouble free service. Lubrication is usually not necessary.

 

ELECTRICAL WIRING shall be done in accordance with the National Electrical

 

Codes or with Local Codes where they prevail. Additional wire shall be of the same size and type as used with existing control circuits. Wiring thereto shall be well secured and reasonably remote from any source of heat.

 

INSTALLER must be a trained, qualified person. Labels and damper position shall be readily visible when in the installed position.

 

- Before interlocking this Damper to a safety control circuit, the heating appliance is to be checked for proper operation, according it its manufacturer's specifications and according to applicable codes.

HOOK-UP PROCEDURE - USING APPLIANACE TRANSFORMER- 24Vac

 

Note: Damper closes by 24Vac power when appliance is not firing, and springs open when appliance fires. Appliance will not fire unless damper is in the open position.

 

Test/Run switch shall be in ‘Run’ position.

 

1. Turn thermo/aqua-stat to lowest setting.

2. Turn off electrical power supply.

3. Connect Damper BLUE (5) wire to

24Vac transformer live side (R on appliance terminal strip) or to the transformer wire leading to the ‘stat.

4. Connect Damper BROWN (3) wire to

24Vac transformer Common side (‘C’ on terminal strip) or to transformer wire leading to ‘TR’ on gas valve

5. Test by turning on power supply.

 Damper will close. Turn off power supply.

6. Remove stat wire connected to ‘W’ on

terminal strip or >TH= on gas valve and with wire nut connect to damper BLACK (1) wire (sensor) *See wiring diagram regarding fuse protection.

7. Connect damper RED wire (2) back to ‘W’ on terminal strip or >TH= on gas valve. (Signal)

8. Turn on power supply and damper will

close. Turn ‘stat to call for heat. Damper will open and appliance will operate normally.

HOOK-UP PROCEDURE USING AUXILIARY TRANSFORMER– 24Vac

Note: Damper closes by 24Vac power when appliance is not firing, and springs open when appliance fires. Appliance will not fire unless damper is in the open position.

Note: Test/Run switch shall be in ‘Run’ position.

 

NOTE: Refer to Instruction #9 for PROPER PHASING of AUXILIARY TRANSFORMER.

 

1. Turn thermo/aqua-stat to lowest setting.

2. Turn off electrical power supply.

3. Connect Damper BLUE (5) to one 24Vac wire of auxiliary transformer.

4. Connect Damper BROWN (3) wire to 24Vac transformer Common side (‘C’ on terminal strip) or to transformer wire leading to ‘TR’ on gas valve together with second wire from auxiliary transformer.

5. Test by turning on power supply. Damper will close. Turn off power supply.

6. Remove stat wire connected to ‘W’ on terminal strip or TH on gas valve and with wire nut connect to damper BLACK (1) wire (sensor) *See wiring diagram regarding fuse protection.

7. Connect damper RED wire (2) back to ‘W’ on terminal strip or TH on gas valve. (Signal)

8. Turn on power supply and Damper should close. IF DAMPER DOES NOT CLOSE, interchange auxiliary transformer wires and Damper will close.

9. Check for PROPER PHASE of AUXILIARY TRANFORMER by momentarily jumping Damper BLACK (1) wire to Damper RED (2) wire. If Damper opens, an out-of-phase transformer is indicated. Correct by interchanging auxiliary 24Vac transformer wires and retest.

10. Turn stat to call for heat. Damper will open and heating appliance will operate normally.

 

TROUBLESHOOTING PROCEDURE IS ON PAGE 4.

 

HAC - F TROUBLESHOOTING PROCEDURE:

 

Note: Test/Run switch shall be in ‘Run’ position during normal operation of the appliance. ‘Test’ position turns off the power to the damper causing it to open while at the same time shorting the end switch which isolates the damper circuit from the appliance. 

If appliance does not fire when the Test/Run switch is in the ‘Test’ position, a faulty furnace circuit is indicated. 

 

NOTE: Whenever Test/Run switch is in ‘Test’ position, Damper shall be in the Open position.

 

Damper does not close after firing cycle:  

 

This indicates:

1) faulty motor; 

2) faulty relay.

 

Procedure: 

Use a jumper between terminals 3 and 4. If damper closes, faulty relay is indicated. No response indicates a faulty motor or lack of power.

 

Damper does not open when stat asks for heat.

This indicates: 

1) Signal is not getting through from stat; 

2) Faulty relay coil; 

3) Faulty return spring to open the Damper.

 

Procedure: 

1) With jumper, join terminals 1 and 5. If damper opens, a faulty stat or fuse (if used) is suspected. Check fuse. Join terminals 1 and 2 and furnace does not fire, a faulty stat is confirmed.
