GAS CONVECTION OVENS
KEEP THIS MANUAL FOR FUTURE REFERENCE
GENERAL
Model GCO2D Gas Convection Oven is a single cavity oven, featuring a solid state temperature control
and 1-hour dial timer. Model GCO2C features a programmable controller. Each oven is equipped with a
25,000 BTU/hr burner and 1/2 HP (0.37 kw) electric motor. Porcelain interior is standard. Each oven is
furnished with five racks; additional oven racks are optional.
Two single ovens can be ordered with a stacking kit for mounting one oven on top of the other.
A single oven may be installed on an open stand with lower storage rack (optional).
Your Vulcan Gas Convection Oven is produced with quality workmanship and material. Proper installation,
usage and maintenance of your oven will result in many years of satisfactory performance.
It is suggested that you thoroughly read this entire manual and carefully follow all of the instructions
provided.
INSTALLATION
Before installing, verify that the electrical service and type of gas supply (natural or L.P.) agree with the
specifications on the oven rating plate, located on the inside of the top front cover. If the supply and
eqipment requirements do not agree, do not proceed with installation. Contact your dealer or Vulcan-Hart
Company immediately.
UNPACKING
This oven was inspected before leaving the factory. The transportation company assumes full responsibility
for safe delivery upon acceptance of the shipment. Immediately after unpacking the oven, check for
possible shipping damage. If this oven is found to be damaged, save the packaging material and contact
the carrier within 15 days of delivery.
Do not use the door or its handle to lift the oven.
LOCATION
The equipment area must be kept free and clear of combustibles. Clearance from combustible or noncombustible construction of at least 3" (7.6 cm) on the sides and 3" (7.6 cm) at the back are required. The
installation location must allow adequate clearance for servicing and proper operation.
The oven must be installed so that the flow of combustion and ventilation air will not be obstructed.
Adequate clearance for air openings into the combustion chamber must be provided. Make sure there is
an adequate supply of air in the room to allow for combustion of gas at the oven burners.

INSTALLING BASIC OVEN
The basic oven must be installed on 4" (10 cm) or 6" (15 cm) adjustable legs for counter installation or be
mounted on a modular stand. Installations on concrete bases or other supports restricting air circulation
underneath the oven are not advisable and may void the warranty.
Ovens Mounted on Casters
Ovens mounted on casters must use a flexible connector (not supplied
by Vulcan) that complies with the Standard for Connectors for Movable
Gas Appliances, ANSI Z21.69 • CSA 6.16 and a quick-disconnect
device that complies with the Standard for Quick-Disconnect Devices
for Use With Gas Fuel, ANSI-Z21.41 • CSA 6.9. In addition, adequate
means must be provided to limit movement of the appliance without
depending on the connector and the quick-disconnect device or its
associated piping to limit appliance movement. Attach the restraining
device at the rear of the oven as shown in Fig. 1.

If disconnection of the restraint is necessary, turn off the gas supply before disconnection. Reconnect this
restraint prior to turning the gas supply on and returning the oven to its installation position.
Separate instructions for installing casters to the oven are included with the casters.
Note: If the oven is installed on casters and is moved for any reason, it is recommended that the oven be
releveled front to back and side to side for even baking.

CHIMNEY
PL-52221
The 4" (10 cm) or 6" (15 cm) legs are packed inside the oven during shipment and must be installed on the
bottom of the oven. Place the oven on its left side, being careful to avoid scratching the finish. The gas pipe
connection protrudes beyond the back; provide for this when oven is tipped back by resting it on suitable
spacers (2 x 4's etc.). Thread each of the four leg assemblies into the holes provided on the bottom corners
of the oven. Carefully raise the oven to its normal upright position.
Assembling the Chimney to the Single Oven
Remove the chimney from inside the oven cavity and use the screws
provided to fasten the chimney to the top rear of the oven (Fig. 2). The
flanges on the chimney are to be positioned over the top cover.
Assembling the Oven to the Stand
Position the oven on its back, taking care not to scratch or damage it. The
gas pipe connection protrudes beyond the back; provide for this when the
oven is tipped back by resting it on suitable spacers (2 x 4's). Install the
two locating studs (included in the stand carton) into the screw plates on
the underside of the oven (Fig. 3).
Attach each of the four leg assemblies to the bottom of the stand with the
12 bolts and lockwashers (3 per leg). If casters are used instead of legs,
put fixed casters in rear and swivel casters in front using 12 bolts and
lockwashers (3 per caster). Mount the oven on top of the stand.
Assembling Stacked Ovens
Determine which oven will be on the bottom and place it on its left side,
being careful to avoid scratching the finish. Install the four 16
3
/4" (42.5 cm)
legs, using the 24 bolts and lockwashers provided (6 per leg). Remove the
7
/16" (1.1 cm) knockouts on each side of the top cover and place oven
two
in upright position at installation location. Turn the adjustable feet in or out
to level the oven front-to-back and side-to-side (refer to LEVELING, page
6).
Remove right side panels from both ovens. Remove welded plate from
bottom of upper oven (Fig. 3). Install the two locating studs (included in the
leg stack set) into screw plates on underside of upper oven (Fig. 3). Place
upper oven on top of lower oven using the locating studs.

Remove flue extension from upper oven. Install long flue extension into
existing right-angled flue extension in lower oven. Attach long flue extension
to wall of upper oven using screws provided. Secure chimney to roof of
upper oven (Fig. 4).
Install right side panels on both ovens. Connect the piping between the top
oven and bottom oven. Pipe joint compound must be resistant to the action
of propane gases.
The manual gas valve at the bottom of the control panel should remain off
until all electrical connections are made and the ovens are checked or
used.

LEVELING
Once the oven is in its permanent position, place a carpenter's level on the oven rack. If the oven is installed
on legs, turn the adjustable feet in or out to level oven front-to-back and side-to-side. If the oven is installed
on casters, loosen set screws and turn casters in or out to level oven front-to-back and side-to-side.
Retighten set screws after leveling.
ELECTRICAL CONNECTIONS
Electrical and grounding connections must comply with the applicable portions
of the National Electrical Code and/or other local electrical codes.
Appliances equipped with a flexible electric supply cord are provided with a
three-prong grounding plug. It is imperative that this plug be connected into a properly
grounded three-prong receptacle. If the receptacle is not the proper grounding type, contact an
electrician. Do not remove the grounding prong from this plug.
The 120 volt models are equipped with a cord and plug.
Refer to electrical wiring diagram located inside the right side panel; remove control panel for access.
Do not turn the power supply on until after the gas connections have been made and checked for leaks.
