3. USING A PALLET JACK
Once the appliance has been removed from the delivery vehicle, it can easily
be moved on flat 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 ON A PALLET JACK IS NOT SAFE!
Contact Wood Stone if the appliance must be turned on its side for specific 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 first priority. Please don’t hesitate to call the factory for technical support.
DO NOT TURN THE APPLIANCE ON ITS SIDE!
DELIVERY NOTE: The customer will receive a Shipping Notification when the unit 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. Thank you.
2. USING A FORKLIFT
Be sure to use a forklift rated to lift more than the appliance weighs as
shown below. Fork length must be at least 6 feet, if not, fork extensions
should be used. The appliance stand is equipped with fork pockets just
above the angle iron base. The appliance is very top heavy so spread the
forks as far apart as possible.
4x4 post
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 sufficient 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.

Mountain Series Installation and Operation Manual
GaS inLet preSSureS
SV-1 and SV-2 are the gas control valves that operate under floor infrared burner and the interior radiant burner, respectively.
SV-1 is located directly behind the service/intake panel and in front of the under floor infrared burner. SV-2 is located
under the appliance to the rear left.
The manifold pressure test port for the infrared under floor burner is a 1/8" NPT plugged tapping located near the left
end of the burner manifold.
The Wood Stone Gas appliances are equipped with a 3/4" NPT gas connection located at the rear left of the appliance.
Have a licensed gas installer provide the hook-up and test all fittings and pipe connections for leaks. Use approved gas
leak detectors (soap solutions or equivalent) over and around the fittings and pipe connections. DO NOT USE FLAME TO
TEST FOR LEAKS!
The burner manifold pressure has been adjusted and tested at the factory. A variety of factors can influence this pressure,
so be sure to test the burner manifold pressure and adjust the valve as necessary to achieve the specified pressure. Note:
The gas valve is shipped in the 'ON' position.
GAS INLET PRESSURES
Inlet pressure must be within the above ranges when the oven is running, and when the oven is off. No external regulator
is required when inlet pressures are within the ranges above. If inlet pressure exceeds 14” W.C. (1/2 psi), an external
regulator, by others, is required to prevent damage to the oven. If inlet pressure is below the minimum pressures shown
above, adjustment or modifications to the supply system will need to be made by the pipe installer and or the gas
supplier.
Proper gas inlet pressures are as follows:
Natural Gas – 6.5” W.C. min to 14” W.C. max
Propane (LP) – 10.5” W.C. min to 14” W.C. max
It is the responsibility of the installer to verify proper gas inlet (supply) pressure to the oven. Problems caused by
improper gas inlet pressure are not covered by the oven warranty. Proper gas inlet pressure is critical to the operation and
performance of the oven.
