appliance is intended for commercial use in locations suitable for use as listed in this manual.

Clearances to combustible and none combustible construction: 0” back, sides and top.

This appliance is suitable for installation on combustible floors.

Installation Codes

For US Installation

The LMO oven must be installed in accordance with all State and local codes and: National Fuel Gas Code, ANSI-Z2231/NFPA 54 (latest edition) National Electrical Code, ANSI/NFPA70 (latest edition)

For Canadian installation

The LMO oven must be installed in accordance with all local codes and; CAN/CGA-B149.1 National Gas Installation Code

The appliance and its individual shutoff valve must be disconnected form the gas supply piping system during any pressure testing of that system at pressures in excess of ½ psi (3.5kPa).

The appliance must be isolated from gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ½ psi (3.5 kPa).

Note: The decorative trim is not intended for use as an exhaust hood.

Model Number Coding LMO followed by G (gas models) or E (electric model)

followed by followed by N (for natural gas) or LP for (Propane gas) or 208, 240 or 480 (for electric models) followed by 6 (6-pan rack) 0r 8 (8-pan rack) followed by S (for stand) or P (for proofer base)

Sample Model Number: LMO-E8-480-P: This is a 480 Volt electric oven with an 8 pan rack and a proofer base.

Utility Connection Points and Dimensional Drawing

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.)

3: Plumbing Connections

WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY AND PLUMBING CODES.

Water Supply

Oven water supply should have a hardness of 4-6 grains per gallon, pH of 6.5 to 8.0 and chlorides of less than 30 PPM. Water conditions outside of these parameters may void the warranty. Please consult your local water company and or water condition dealer before installing the ovens water supply.

Connect the cold water supply to the ½”

NPT fitting located at the rear of the oven with a 6’-00” flexible water line.

Drain Connections

Connect a ½” drain line to the ½” NPT

drain connector located at the rear of the oven. Route the drain line to a floor drain

allowing a minimum 1” air gap between

the drain line outlet and the floor drain.

If the oven is being used with a proofer insert it is recommended that separate drain and water lines are provided.
