Cleveland ogb-10.10 Manuel Complémentaire

◊

  When this speed is attained the signal is sent from terminal 2 of connector

X2 on the Steam Power Burner and Fan Control (U21) to terminal 9 of
connector X24 on the Gas Board (A20)

•

  A request for heat is sent from terminal 3 of connector X21 on the Gas Board

(A20) to terminal 10 on connector X1 on the Steam Burner Control Module
(N21)
◊

  24 VAC is sent from terminal 2 of connector X2 on the Steam Burner

Control Module (N21) to the hot surface igniter (R20).

◊

  The gas valve is energized allowing gas and air into the burner chamber to

be ignited by the hot surface igniter.

◊

  The Steam Burner Control Module (N21) senses at least 1.5 micro amps

DC from the flame sensor (P1) at terminal 3 of connector X2 and sends a
signal from terminal 2 of connector X1 to terminal 11 of connector X25
on the Gas Board (A20)

e

  After the bypass probe (B5) is satisfied then the hot air heat circuit is energized to

increase the cabinet temperature to the setting.
•

  A signal is sent from terminal 2 of connector X24 on the Gas Board (A20) to

terminal 4 of connector X2 on the Hot Air Power Burner and Fan Control
(U20) selecting the set speed of the combustion blower.
◊

  When this speed is attained the signal is sent from terminal 2 of connector

X2 on the Hot Air Power Burner and Fan Control (U20) to terminal 3 of
connector X24 on the Gas Board (A20)

•

  A request for heat is sent from terminal 3 of connector X20 on the Gas Board

(A20) to terminal 10 on connector X1 on the Hot Air Control Module (N20)
◊

  24 VAC is sent from terminal 2 of connector X2 on the Hot Air Control

Module (N20) to the hot surface igniter (R20).

◊

  The gas valve is energized allowing gas and air into the burner chamber to

be ignited by the hot surface igniter.

◊

  The Hot Air Burner Control Module (N20) senses at least 1.5 micro amps

DC from the flame sensor (P1) at terminal 3 of connector X2 and sends a
signal from terminal 2 of connector X1 to terminal 10 of connector X25
on the Gas Board (A20

•

  The heat circuit will remain energized until the cabinet set temperature is

reached

•

  If the bypass probe (B5) drops below the set level the steam heat circuit will

start again.

f

  When the condensate box is heated to 140 degrees F at the B3probe, 120 VAC is

sent from terminal 5 of connector X12 to the condenser valve (Y1) until the
temperature drops.

g

  If the “Crisp and Tasty” mode is selected

•

  120 VAC is sent from terminal 6 of connector X12 on the Control Board

(A10) to the Dehumidification Valve (Y2) to pull the humidity out of the
cabinet down the drain.
◊

  In the light and medium modes (one and two drops in the display) the Y2

valve will be energized until the bypass probe (B5) is satisfied.
