ASSEMBLING STACKED OVENS (OPTIONAL)
STACKING FLUE
Unpack the ovens and stack kit. Position the oven to be used as the bottom oven on its back for access to the oven bottom, taking care not to scratch or damage it. The gas pipe protrudes beyond the back; provide for this when the oven is tipped back by resting it on suitable spacers (2 x 4's, etc.). Attach the four leg assemblies with the 24 bolts and lockwashers (six per leg).
Place the lower oven (with legs) on the floor and remove two 7/16 inch (11 mm) diameter knockouts on each side of the top cover. Remove vent guard and discard it.
Move the oven with legs to the installed position and place upper oven on top of lower oven using the locating studs.
Install the stacking flue (Fig. 3) with the four screws provided.
Connect the piping between the top oven and bottom oven. For all gas supply connections, pipe joint compound must be resistant to the action of propane gases.

LEVELING
Make sure that the oven racks are level in the final installed position. If the oven is installed on legs, turn the adjustable feet in or out to level the oven
GAS CONNECTION
Gas supply connections and any pipe joint compound must be resistant to the action of propane gases.
Location of the gas inlet is at the rear of the oven. Codes require that a gas shutoff valve must be installed in the gas line ahead of the oven.
Connect gas supply after leveling the oven. The gas supply line must be at least the equivalent of 3/4 inch (19 mm) iron pipe. Make sure the pipes are clean and free of obstructions, dirt or pipe joint compound.
The ovens are equipped with fixed burner orifices which coincide with installation elevation.
The oven is provided with a regulator integral to the gas solenoid valve and requires no external regulator.
Natural gas pressure regulators are preset for 3.5 inches W.C. (Water Column) (0.9 kPa); propane gas pressure regulators are preset for 10 inches W.C. (2.5 kPa).
Prior to lighting, check all joints in the gas supply for leaks. Use soap and water solution. Do not use an open flame.
A. Check all joints prior to the gas valve (solenoid) before lighting unit.
B. Check all joints beyond gas valve (solenoid) after unit is lit.
After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.
