STACKING INSTRUCTIONS, GCSF Oven

These stacking instructions apply when two units are being installed in a stacked arrangment only. When
an GCSF is in the top position, in a stacked assembly, the draft inducer wiring harness is needed to power
the inducer. The GCSF is the bottom position of a stacked assembly, must have the draft inducer wiring
harness removed.

When stacking an GCSF (gas) with a ECSF (electrical), put the GCSF on top to ensure proper venting of

combustion gasses.

1. Attach the feet or casters to the lower oven per the previous “Leg & Caster Installation” section.

2. Remove the Button Plug from the top right hand of the lower oven and replace it with the 1 3/4” plastic

electrical bushing provided in the stacking kit,

see illustration.

3. Remove the

To accomplish this:

• Cut the 9 pin and the two single connectors coming through the top of the lower unit.

• Remove the Side Access Panel & the Terminal Block Access Panel on the lower oven.

• Disconnect the wires from the harness going to the terminal block.

• Locate the bundle of wires in the side access panel labeled “

”,

disconnect the wires from the oven harness at the 6 pin connector.

• The draft inducer harness can now be removed from the unit by pulling the harness from the

control side through the firewall bushing

REMOVE THE INDUCER KNOCKOUT

on the right rear

through the plastic electrical bushing at the bottom of the

oven and into the lower oven.

EnviroZONE only

: Install a 1 3/4” plastic electrical bushing,

replacing the knock-out directly behind the control cooling

fan of the lower oven.
