Installation
The LMO oven must be installed on the ovens stand using the supplied fasteners or installed on any non-combustible surface adequate to support the weight of the appliance.
Ovens shipped with a stand must have the casters installed.
With the oven still on the shipping pallet slide the oven and stand forward and install the two front locking casters.
Move the oven and stand forward onto a pallet truck, lift the oven and stand off of the pallet and install the two rear casters.
IMPORTANT:
Gas ovens can not be mounted directly to a solid surface as the combustion air intake is from the bottom side of the oven.
ALL GAS MODELS MUST BE MOUNTED ON OVEN STAND OR PROOFER BASE
Secure the oven to the stand or proofer base with the supplied self-tapping fasteners.
Gas ovens mounted on the oven stand with casters must utilize the following…
A connector that complies with the Standard for Connectors for Movable Gas Appliances, ANZI Z21.69 Or Connectors for Movable Gas Appliances, CAN/CGA-6.16 A quick disconnect device that complies with the Standard for Quick-Disconnect Devices for Use With Gas Fuel, ANZI Z21.41 Or Quick Disconnect Devices for Use with Gas Fuel, CAN1-6.9 Adequate means must be provided to limit the movement of the appliance.
Select a location that has a smooth level surface and has adequate room to operate the appliance (see Illustration – 1 for oven dimensions and utility connection points)
Ensure that the oven is installed on a level surface. If the unit is mounted on the movable oven stand, loosen the caster bolt and place shims under the base until level, re-tighten the caster bolts.
Pick Points: Use adequate material handling equipment to lift the oven into place, oven weight is 1,100 lbs.

1: Gas Connections
CAUTION: Gas supply connections and any pipe joint compound must be resistant to the action of propane gases.
The LMO-G is an indirect gas fired oven consisting of a heat exchanger that consists of 15 (fifteen) in-shot burners and tubes totaling 90,000 BTU/HR.
Verify that the gas supply matched the type listed on the data label. If the incoming
pressure exceeds ½ psig (3.45kPa) 14” W.C. install a pressure regulator before the oven’s
gas valve.
Codes require installation of a gas shutoff valve in the gas line ahead of the oven. The gas supply line must be at least the equivalent
of ¾” iron pipe. Corrugated lines should not
be used.
Connect the gas supply line to the ¾” NPT
incoming gas connection located at the rear of the oven. Ensure that the pipes are free and clear of any dirt or obstruction. If the oven is supplied with a flexible gas line, secure it to the oven and wall per the manufacturers instructions.
Verify that the line pressure before the gas valves stays between 5” and 14” W.C. for
natural gas or 11” and 14” for W.C. for
propane gas – both with and without the burner firing.
For conversion to Propane Gas or to Natural Gas:
1. Shut off the gas supply to the oven.
Remove the bottom burner cover and the side access cover.
2. Disconnect the gas line at the top of the
gas valve. Remove the four extended nuts at the bottom of the turner assembly. Lower the burner out of the oven.
3. Remove the 15 orifices and replace with
the orifices listed on the burner/heat exchanger parts list in this manual. Use approved Teflon tape to seal the orifices.
4. Replace the burner. Reconnect the gas
line, replace the covers. Check for leaks.
5. Operate the burner. Adjust the gas
pressure to the correct pressure listed in the burner/heat exchanger parts list in this manual.
6. Apply proper labeling to indicate the
correct gas and pressure on the data plate and at the gas connection point.
2: Ventilation
Ventilation requirements vary with each installation and must comply with applicable portions of the National Fire Protection Association Standard 96 as well as any and all State and local codes.
Exhaust Fan Interlock
A connection point (5 AMPS Max.) is provided for indirect vent (Exhaust Hood) or optional direct vent (Draft Hood). It is located in the electrical connection box at the right rear side of the oven. Consult local codes for vent interlock requirements.
Indirect Vent (Installed under an exhaust hood) – Standard installation configuration.
Locate the oven under an exhaust hood with adequate overhangs and exhaust rates to completely capture the byproducts of combustion discharged from the flue. From
the termination of the flue to the filters of the
hood venting system a clearance of 18” must
be maintained. The exhaust hood fan can be directly interlocked to the oven (consult the wiring diagram for terminal location*).
Direct Vent (Draft Hood) – Optional configuration
Move the oven into position and attached the customer supplied exhaust ducting and draft diverter. Verify that the air is being drawn into the bottom of the draft diverter while the burner is firing, using a draft gauge or smoke test. Using a draft gauge, verify that a draft of
between 0.03” – 0.11” W.C. is maintained at a point 6” above the draft diverter’s upper
collar. Any exhaust fan or draft inducer used to maintain system suction must be operating when the oven is turned on. (See exhaust fan interlock.)
