4. STACKING
These ovens can be stacked up to three high. Each unit is built exactly the same, so it does not matter in what order they are stacked. However, in case of a mix of 8” and 12” deck heights, it is advisable to place the higher deck(s) on the top, e.g.: mount the legs to one of the lower decks.
Once the unit with the legs is in place (in case of casters make sure the brakes are on), with the proper lifting equipment gently place the next oven on top of the first one and line up the back and sides with each other. (If the ovens came with Steam Option, read section 5. below before proceeding). Once the two ovens are properly stacked, install the stacking brackets as per instructions supplied with the kit. In case of a third unit, gently place the oven on top of the second one, line up the back and sides, then connect to the stacking brackets.
5. STEAM OPTION
If this option has been ordered and supplied, remove the control panel(s) and left access cover(s) to gain access to the steam plumbing as follows:
a)Remove all screws and vent knob from the control panel. Loosen the set screw on the thermostat knob and remove it. Pull the control panel out at the bottom, then down and out from the vent rod. Slip the right flange hole of the control panel back onto the vent rod, then replace the vent knob to keep the control panel in an open and secure position. (See fig. 5l)
b)Remove all screws from the left access panel, then pull it forward and out of the oven.
c)After the internal pipe connections have been completed as per instructions below, follow the instructions supplied by the manufacturer of the steam generator and the manufacturer of the steam trap for final hook up to the steam supply.
Stacked ovens
a)In all but the top oven, punch four 1 1/2” diameter holes in each of the top covers, utilizing the 1/8 locating holes. (See fig. 5b)
b)Loosen the upper pipe union(s) and remove the upper part(s) from all but the top oven. (See fig. 5c).
c)Raise the left side of the upper unit and place a piece of wood or similar material to keep a 1” to 1 1/2” space between the two ovens.
d)Insert the connecting pipe, small end up, (see fig. 5d) through the access opening of the lower unit and screw it into the lower pipe union of the upper oven, leaving a space between the lower union sections identical to the space between the two ovens.
e)Lift the upper unit, remove the spacer and carefully lower it until the two union parts in the lower oven meet. Adjust the height of the connecting pipe, if necessary, to have a perfect match at the lower union, then tighten the lower union.
WARNING: It is very important to have a good match at the lower union before tightening it. If the connecting pipe is too long or too short, this will put undue stress on the pipe joints and could cause failure of these components and property damage or injuries as well.
f)At the end, insert the connecting pipe, small end up, through the appropriate opening at the base of the bottom unit and screw it into the lower pipe union.
Single Oven
Insert the connecting pipe, small end up, through the appropriate opening of the base and screw it into the lower pipe union. (See fig. 5e)
