Cleveland ogb-10.10 Manuel Complémentaire

•

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.

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.

When the timer counts to 0 or the core temp probe (B10) reaches the set amount

the cycle ends and the steam generator reverts to the standby temperature of 190-
degree F.
