INSTALLATION

UNPACKING

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.

Prior to installation, verify that the electrical supply and type of gas (natural or propane) agree with the specifications on the oven data plate, located on the inside of the top front cover.

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" installation location must allow adequate clearance for servicing and proper operation.

(7.6 cm) on the sides and 3" (7.6 cm) at the back are required. The

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.

When the oven is mounted on casters, it must be installed with the casters supplied, a connector (not supplied by Vulcan-Hart) complying with either ANSI Z21.69 (latest edition) or CAN/CGA-6.16 (latest edition), and a quick-disconnect device complying with either ANSI Z21.41 (latest edition) or CAN1-6.9 (latest edition). It must also be installed with a restraint device to prevent strain on the connector. Remove two screws from the rear of the oven and install the tie down strap shipped with the casters using these screws. Attach the gas line strain relief to the tie down strap at the rear of the oven (Fig. 1).

Assembling the Legs to the Single Oven

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.).

CHIMNEY

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

PL-52240

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

FRONT OF TOP OVEN

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

(42.5 cm) legs, using the 24 bolts and lockwashers provided (6 per leg).

Remove the two

⁄4"

and place oven in upright position at installation location. Turn the adjustable feet in or out to level the oven front-to-back and side-toside (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.
