UNLOADING & MOVING
2. USING A PALLET JACK
Once the oven has been removed from the delivery vehicle, it can easily be
moved on flat surfaces using a Pallet Jack. To lift the oven with a Pallet Jack,
remove the front and rear angle iron stabilizers from the base of the oven stand
and place a stout 4x4 post through the Fork Pocket as shown in figure b.
THE OVEN IS VERY TOP-HEAVY. MOVING THE OVEN UP OR DOWN A RAMP
OR INCLINE ON A PALLET JACK IS NOT SAFE!
DELIVERY NOTE: The customer will receive an Oven Shipping Notification when the oven leaves the Wood Stone factory. This
will include a PRO# and a trucking company contact number. Wood Stone recommends that you confirm the delivery date/time
with the trucking company before committing to heavy equipment and/or labor. Our goal is a smooth and safe delivery.
4x4 post
1. USING A FORKLIFT
Be sure to use a Forklift rated, and Forks the minimum length,
as shown in the table below. If necessary, Fork Extensions must
be used so the Forks extend through the Fork Lift Pockets to the
opposite side of the stand. Lift from either side as shown in figure
a. Do not lift from the front or back. The oven is very top heavy, so
spread the Forks as far apart as possible.

3. USING A CRANE
The oven arrives with four lifting eyes attached. When craning a Wood Stone
oven, use a spreader bar with a two-legged sling rigged on each end. The
spreader bar should be of a sufficient length to keep the sling from contacting
the oven. See figure c.
DO NOT TURN THE OVEN ON ITS SIDE!
Contact Wood Stone if the oven must be turned on its side for specific instructions.
Moving a Wood Stone oven can present challenges to even the most experienced
riggers. Take your time, use your head, secure the proper equipment and make
safety your first priority. Please don’t hesitate to call the factory for technical
support.
LIFTING THE OVEN
NOTE: Once Pickeyes are no longer needed, remove the Pickeyes one at a
time AND BE SURE TO REPLACE THE BOLTS THAT ATTACH THE OVEN
TO THE STAND.

FACADE DETAILS
Wood Stone Mountain Series (MS-) ovens carry an ETL Sanitation listing. The oven interior only is ETL listed to NSF/ANSI
Standard 4. This means that the surfaces of the oven which are meant to be left exposed after the facade has been put in place
have been evaluated from the standpoint of sanitation and food safety and found to comply with NSF/ANSI Standard 4. To operate
the oven in accordance with NSF/ANSI Standard 4, only pizza and bread products may be cooked directly on the floor of the oven.
Other types of food may be cooked on or in pans, or other suitable containers to prevent spillage onto the oven deck.
Go to www.woodstone-corp.com for detailed instructions for constructing a facade around a Wood Stone oven.
A removable Service Panel or storage box allows
access for service of gas and electrical components.
If this panel is not used, access and air intake of
equivalent dimensions MUST be provided at the
front of the oven.
If using an exhaust hood over the oven, make sure
your facade allows proper access for removal of the
hood filters.
Hatched areas shall not be exposed after installation of facade.
Any facade wall 6” to either side of the oven doorway and above
MUST be of non-combustible construction with no exceptions.
