Cleveland Range OGS-10.10 - Manual (Page 80)

• 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
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.
