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

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.

Mountain Home Oven Installation and Operation Manual
GAS INLET PRESSURES
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 opera-
tion and performance of the oven.
Proper gas inlet pressures are as follows:
NATURAL GAS NG  6.5" W.C. MIN TO 14" W.C. MAX
PROPANE LP  10.5" W.C. MIN TO 14" W.C. MAX
Inlet pressure must be within the above ranges when the oven is running, and when the oven is o. 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 modications to the supply system will need to be made by the pipe
installer and or the gas supplier. This appliance requires no modications or adjustments for use at high altitudes
Incoming gas pressure (NG or LP) must not exceed 1/2 psi (14" W.C.) if incoming gas pressure exceeds 1/2 psi, an
external regulator, provided by others, must be installed.
The Wood Stone Gas appliances are equipped with a 3/4" FNPT gas connection located at the rear left of the
appliance. Have a licensed gas installer provide the hook-up and test all ttings and pipe connections for leaks.
Use approved gas leak detectors (soap solutions or equivalent) over and around the ttings and pipe connections.
DO NOT USE FLAME to test for leaks!
SV-1 and SV-2 are the gas control valves that operate under oor infrared burner and the interior radiant burner,
respectively. SV-1 is located directly behind the service/intake panel and in front of the under oor infrared burner.
SV-2 is located under the appliance to the rear left.
The manifold pressure test port for the infrared under oor burner is a 1/8" NPT plugged tapping located near the
left end of the burner manifold.
The manifold pressure test port for the radiant burner is a 1/8" NPT plugged tapping located at the base of the
T-junction between the SV-2 valve and the radiant/interior burner.
The burner manifold pressure has been adjusted and tested at the factory. A variety of factors can inuence this
pressure, so it may be necessary to test the burner manifold pressure and adjust the valve as necessary to achieve
the specied pressure. Note: The gas control valves are shipped in the ON position.
Specied burner manifold pressures shown on following page.

Mountain Home Oven Installation and Operation Manual
The following are the manufacturer’s recommendations for venting the Wood Stone MH (Mountain Home Series)
appliance. It is never appropriate to use “B vent” in any part of an exhaust system connected to a Wood Stone
appliance. All duct material must be Listed to UL 1978, or fabricated to the specications of a grease duct. Submit
your venting plans to your local authorities before proceeding with your installation, as there may be additional
requirements in your area. All residential venting systems should be inspected yearly and cleaned as necessary.
There are two options:
1. A power ventilated grease duct system listed to UL 1978 connected directly to the appliance ue collar. The
power ventilator (fan) must be rated for a minimum of 300 °F, 450 °F for RFG-IR-W models that burn wood.
Wood Stone oers fans that meet the above requirements. Please contact your dealer or the factory. Wood
Stone does not recommend the use of an in-line fan. A eld built grease duct, constructed and installed to the
specications of a grease duct as detailed in NFPA 96 or the International Mechanical Code, may also be used.
A static pressure of -0.1 inches W.C., (-0.14 inches W.C. for wood burning models,) is necessary at the appliance
ue collar to ensure proper airow. The CFM required to attain this static pressure will be approximately 500
CFM.
Note: For installations vented with a vertical exhaust run, with or without one or more osets, a power
ventilator is not required. However, if any part of the duct run is horizontal, a power ventilator IS
required to ensure proper draft.
Note: When using a direct connection as described above, the duct must be attached to the appliance
ue collar with a full perimeter weld, or an approved connector.
It is never appropriate to use“B vent” in any part of an exhaust system connected to a Wood Stone appliance.
All duct material must be manufactured to the specications of a grease duct. Install venting system in accor-
dance with the duct manufacturer’s instructions and in accordance with all local codes. All eld built compo-
nents should be built to the applicable codes and standards and are subject to the approval of the authority
having jurisdiction.
2. A Listed Type 1 Exhaust Hood or one that is constructed and installed in accordance with all relevant Local and
National Codes. Wood Stone oers eyebrow-type hoods designed specically for Wood Stone appliances. See
specication sheet on ventilators for Wood Stone appliances. If a hood is used, it must be installed in accor-
dance with the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations - NFPA
96. Refer to the hood manufacturers recommendations for inspection, maintenance and cleaning. Contact
Wood Stone for more information about approved exhaust hoods.

Mountain Home Oven Installation and Operation Manual
All Mountain Home ovens are approved for outdoor installation. The unit may be installed in a weatherproof
enclosure. If so be sure to maintain all clearances and adhere to the installation requirements included in this
manual.
For outdoor installations, the indoor installation methods mentioned previously in this manual may be used, OR
when installed outdoors or in an open air outdoor structure such as a covered patio or similar structure, the oven
may be vented without the use of an exhaust fan when the duct run includes no horizontal sections. A natural
draft duct, listed or constructed to the requirements of a grease duct as described in NFPA 96 or the International
Mechanical Code, attached directly to the oven ue collar may be used. The duct must be sucient length and
installed in such a manner that proper clearances from combustible construction and proper clearances in regards
to the termination of the duct are maintained (i.e. clearances from roofs, window and door openings, etc.) All
clearances must be in accordance with NFPA 96, the International Mechanical Code or the applicable local code
in force. All manufactured duct systems must be installed in accordance with the duct manufacture's listing and
instructions.
When the oven is installed free standing outdoors or in its own non-combustible enclosure, no fan is required, and
a suitable metal, stone, clay or ceramic pipe may be used to extend the ue collar outlet above the oven.
Be aware that wind blowing directly at the oven can cause performance and reliability issues. When installing
the oven outdoors choose a location that best minimizes wind exposure for the oven. Please note: keep the area
around and beneath the appliance clear of grass, leaves and other combustible materials.
The appliance is available with an optional collapsible chimney assembly with rain cap (shown below) for use with
freestanding outdoor installations without a roof structure above the oven. Contact your dealer or Wood Stone for
more information.
In the retracted position, the optional collapsible chimney assembly with rain cap closes o the ue opening to
protect from water, leaves etc. getting into the oven when not in use.

Put the stone in place and apply light
pressure to seat it properly. Make sure
that the angle in the granite lines up
with the angle in the bracket. Allow
the sealant to set for several hours
before lling any gap between the
stone slab and the metal bracket with
the silicone compound (provided).
Clean up any sealant before it dries.
INSTALLATION OF GRANITE - After completing the steps outlined above, apply a generous amount of silicone
sealant (provided) to the top of the steel mantle bracket.
The initial steps are the same for mounting either a stainless mantle or a bracket for a granite mantle.
1. Begin by installing the threaded studs into
the clip nuts below the oven doorway (3 or
4 turns is sucient).
2. Position the mantle (or bracket) on the
oven, making sure the rear ange rests on
the oor of the oven (you may need an
extra pair of hands).
3. Place one stainless steel washer and a cap
nut onto each stud. Tighten the cap nuts so
the mantle is securely held in place.
4. Using the high temperature silicone
sealant (provided), ll any gaps between
the oven hearth and the mantle ange.
Gaps between the mantle ange and the
stainless steel doorway frame may also
need to be lled with a small amount of
the silicone sealant. Clean up any sealant
before it dries.
