UNCRATING
The oven will arrive completely assembled inside a wood frame. Prior to uncrating move the
oven as close to its nal location as practical. This will protect it from damage associated with
moving (scratches, dings, dropping).
Some hardware, (i.e. casters, legs, stacking kits) may be shipped inside the oven.
Please remove any items before continuing.
It may be necessary during the installation to place the unit on its side (i.e. leg, caster installation,
t through doors, etc) follow these guidelines to lessen the risk of damage to the unit.
Control

A ventilation hood may be required to remove heat and cooking odors. The hood and HVAC
installation must meet local codes to gain approval by the authority having jurisdiction.
Requirements may vary throughout the country depending on the location by city, county, and
state. Obtain information from the authority having jurisdiction to determine the requirements for
your installation. Obtain information and review copies of codes or documents that will be used
to inspect and approve your installation. Your ventilation hood supplier and HVAC contractor
should be contacted to provide guidance.

DOUBLE STACKED UNITS
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 LOWER OVEN, Draft Inducer Wiring Harness, this is not needed for the lower unit.
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 “DRAFT INDUCER CONNECTION”,
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 rewall bushing
4. REMOVE THE INDUCER KNOCKOUT on the right rear
of the UPPER UNIT ONLY, prior to placing it into position.
DO NOT remove the knockout for the lower unit, doing so
will interupt proper gas venting from that unit.
5. Using the Strapping Plates (see stacking kit) secure the
two ovens together, by mounting them into the existing side
panel, using existing screws on both sides of the unit.
6. Install the vent shroud with 4 #10 sheet metal screws,
provided.
7. Remove the side access panel from the upper oven.
8. Locate the wire bundle labeled “Lower Oven Draft Inducer
Connection” in the upper oven. Pass this connection
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.
9. In the lower oven, connect the 6 pin connector that was
passed through from the upper oven to the connection
marked “Draft Inducer Connection”
10. Replace the side access panels & attach the earthquake
strap (not included) to the eye bolt to the upper oven, see
illustration.

EARTHQUAKE STRAPS
If the oven is to be installed with casters, it must be secured to the building structure. To do
this, attach an oven earthquake strap (not supplied) to the eye bolt (supplied) at the bottom
right corner of the oven. For stacked ovens, attach the strap to the eye bolt of the uppermost
oven. Connect the earthquake strap to the wall or other structure per instructions supplied
with the strap.

UTILITY INSTALLATION
WATER CONNECTION
It is vital that the water supply line be thoroughly ushed with clean water before being connected
to the oven’s water manifold.
After your water has been tested and meets the minimum requirements (see water requirements).
Connect water supply to 3/8” NPTM tting located at right rear corner of the oven. Once the
water manifold and water supply are connected to the oven turn the oven ON and press the
1-shot steam button for 1 minute to remove the air and any impurities from the system.
The water must continuously be within the specications (for this application) while this unit is
in service. Periodic testing may be needed to verify any changes in water conditions.
DRAIN CONNECTION
Attach drain plumbing to the ¾” NPTM oven drain tting located
at the lower rear right had corner of the oven.
Drains need to have a vent pipe attached. Typical venting is
accommodated by using a “T” off the drain pipe with an 8” to
10” open pipe in the top part of the “T”. for stacking, the drains
can be manifolded together with only the top drain vented.
ELECTRICAL CONNECTION
All electrical connections must be made in accordance with
local codes or in the absence of local codes with NFPA No.
