Unloading and Moving

Mountain Home Oven Installation and Operation Manual
LIFTING THE APPLIANCE
1. USING A CRANE
The appliance arrives with four lifting eyes attached. When craning,
use a spreader bar with a two-legged sling rigged on each end. The
spreader bar should be of a sucient length to keep the sling from
contacting the unit.
NOTE: Once lifting eyes are no longer needed, remove the lifting
eyes one at a time and be sure to replace the bolts that attach to
the appliance stand.
2. USING A FORKLIFT
Be sure to use a forklift rated, and folks the minumum length, as
shown 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. Do not lift from the front or the back.
The appliance is very top heavy, so spread the forks as far apart as
possible.
3. USING A PALLET JACK
Once the appliance has been removed from the delivery vehicle, it
can easily be moved on at surfaces using a pallet jack. To lift the
appliance with a pallet jack, remove the front and rear angle iron stabilizers
from the base of the stand and place a stout 4x4 post through the fork pocket
as shown. The appliance is VERY TOP-HEAVY, MOVING THE appliance UP OR
DOWN A RAMP OR INCLINE ON A PALLET JACK IS NOT SAFE! 4x4 post

DO NOT TURN THE APPLIANCE ON ITS SIDE!
Contact Wood Stone if the appliance must be turned on its side for specic instructions. Moving a Wood Stone
appliance can present interesting challenges to even the most experienced riggers. Take your time, use your head,
secure the proper equipment and make safety your rst priority. Please don’t hesitate to call the factory for techni-
cal support.
DELIVERY NOTE: The customer will receive a Shipping Notication when the unit leaves the Wood Stone
factory. This will include a PRO# and a trucking company contact number. Wood Stone recommends that you
conrm the delivery date/time with the trucking company before committing to heavy equipment and/or labor.
Our goal is a smooth and safe delivery.

Clearances

Mountain Home Oven Installation and Operation Manual
IF THIS APPLIANCE IS NOT PROPERLY INSTALLED A FIRE MAY RESULT. TO REDUCE THE RISK OF FIRE, FOLLOW
THESE INSTALLATION INSTRUCTIONS. A MAJOR CAUSE OF APPLIANCE RELATED FIRES IS FAILURE TO MAINTAIN
REQUIRED CLEARANCES AIR SPACES TO COMBUSTIBLE MATERIALS. IT IS OF UTMOST IMPORTANCE THAT THIS
APPLIANCE BE INSTALLED ONLY IN ACCORDANCE WITH THESE INSTRUCTIONS.
CLEARANCES
1. The Wood Stone MH models require a minimum 1" clearance to combustibles from all sides, and 6" clear-
ance to combustibles from the top. If building a facade that will contact the appliance, use completely
non-combustible materials. Please note that standard Drywall (or Sheetrock) is considered a combustible. Side
and top clearance to non-combustibles is 0".
2. Any facade 6" to either side of the appliance doorway and above must be constructed of non-combustible
building materials. Do not pack the required air spaces with insulation or other materials.
3. This appliance must be installed on a non-combustible oor surface (Cet appareil doit être installé sur une
surface de plancher non-combustible). As with any cooking equipment, we suggest that care be taken when
choosing the surfaces in front of the appliance to protect them from potential damage from hot, heavy items
that may be removed from the cooking chamber.
4. For models that burn wood, the non-combustible oor surface should extend 36" out in front of the appliance,
and extend 30" to either side of the appliance doorway.
NOTICE: For stucco-ready appliances (model numbers ending in“-S”), the same clearances as described above
apply. Non-combustible stucco mix must be used and applied to a minimum thickness of 1". When non-combus-
tible building materials contact the body of the appliance, the clearances to combustibles are transferred to those
non-combustibles.
