PREPARING THE OVEN FOR INSTALLATION

Legs and Casters

NOTE: If you will be installing an open base kit, please skip to the next page and proceed with the steps listed under “Open Base Assembly..”

1.(See Figure 1..).. At the bottom end of each leg, install the bullet foot insert or caster insert.. The fit of the insert to the leg is intended to be snug, tap them lightly into place with a mallet or rubber hammer..

Install two #5 x 1/4” self-drilling, thread forming screws into each caster insert..

2.Screw a caster into the insert on each of the four legs.. The caster must be inserted at least three full threads to properly support the oven.. A 1” (25mm) open-end wrench may be needed to properly install the casters..

Using your fingers, screw the ends of the bullet feet into the leg clockwise until they are at their shortest length..

3.Carefully tip and lower the oven onto its left side so you can easily reach the bolt mounting locations in the base..

4.The four holes in the top of each leg or in the top plate of double stack casters will match the bolt locations at each corner of the oven base..

You will need four 3/8-16 x 1” hex head bolts and four 3/8” flat washers to mount each leg.. Align the leg to one of the matching bolt holes on the base and insert a bolt with washer..

Install the remaining three bolts and finger-tighten all four before using an 11/16” wrench to fully tighten them all.. Be sure to tighten all four bolts for each leg or caster.. When installing casters, make sure the two casters with brakes are installed at the front of the oven..

5.Carefully return the oven to an upright position.. Ensure the two legs/casters that touch the floor first when you raise the oven are blocked and chocked so they do not slip away..

6.It is very important to use the adjustable bullet foot inserts in leveling the unit.

7.If you have installed casters, be sure to install the restraint bracket on the lower left corner of the rear of the oven using two #10 x 3/4” sheet metal screws..

PREPARING THE OVEN FOR INSTALLATION

Open Base Assembly

Use the following sequence of steps to assemble and install the open base accessory..

1.(See Figure 2..).. Align the rack guide upper support to the corresponding holes in the oven base.. Fasten using three #10 x 3/4” machine screws on each side of the oven..

2.At the lower end of each leg install an “L” shaped support clip using a #10 x 3/4” sheet metal screw.. Do this before fastening the leg to the base..

3.Install legs to the bolt holes at the front and rear of the base on the oven’s left side, (side lying on the floor).. If installing casters, be sure to install a locking caster on the front leg.. Refer to the section, “Legs and Casters,” on the previous page for installation details..

4.Fasten the open base panel in place on the brackets of the two legs already installed, using one #10 x 3/4” sheet metal screw in each corner..

5.While supporting the open base panel, install the rightside legs as in step 2.. Ensure the caster with a brake is at the front of the oven.. Fasten the remaining two corners of the open base panel to the other two legs just installed..

6.Carefully return the oven to an upright position.. Ensure the two legs/casters that touch the floor first when you raise the oven are blocked and chocked so they do not slip away..

7.Install the rack guides in one of the two available positions.. The inner position sets the guides at a width to accommodate oven pans.. The outer position sets the guides at a width to accommodate wire oven racks.. To

attach, insert the longer straight end at the top of the rack guide all the way into the mounting hole, then align the bottom holes and lower the rack guide into position..

8.It is very important to use the adjustable bullet foot inserts in leveling the unit.

9.If you have installed casters, be sure to install the restraint bracket on the lower left corner of the rear of the oven using two #10 x 3/4” sheet metal screws..

PREPARING THE OVEN FOR INSTALLATION

Stacking Two Ovens

1.Follow the instructions in the section entitled, “Legs and Casters,” on page 5.. Then resume at step 2 on this page to complete the stacking process..

2.Move the lower oven as close to the final installation point as possible, leaving enough space around the oven to allow access for the remaining installation steps.. If casters have been installed, apply the brakes on the two front wheels..

3.Carefully raise the upper oven and place it on top of the lower oven, aligning the four lower corners of the upper even to the four upper corners of the lower oven..

4.At the rear of the stacked ovens, install the stacking bracket using six 1/4-20 x 1” hex head bolts with lock washers and nuts.. Firmly tighten all six nuts/bolts to secure the ovens together..

5.Remove the outer flue vent from the right top corner of the rear of each oven, saving the screws..

6.If they are not already fastened together, assemble the two parts of the interconnecting flue channel included in the stacking kit, using six #10 x 3/4” sheet metal screws..

7.Fit the channel assembly over the flue vent area of each oven and fasten using the screws removed in step 5..

8.If you have installed casters, be sure to install the restraint bracket on the lower left corner of the rear of the upper oven using two #10 x3/4” sheet metal screws..

9.If your installation requires one common gas inlet for both ovens, use the piping included with your stacking kit to assemble the interconnecting gas pipe.. Refer to Figure 3..

NOTE: It is recommended, when stacking a Moisture + Oven with a Master Convention Oven, that the Moisture + be located on the bottom..

INSTALLATION

It is the responsibility of the purchaser to ensure the oven is installed in a manner to meet all local codes.. In the absence of local codes, applicable national codes are referenced in this booklet.. In the case of discrepancy between the information in this booklet and local codes, it is recommended you consult your local inspector(s).. This appliance meets or exceeds all applicable regulations and standards in effect on its date of manufacture..

Location

The importance of the proper installation of Commercial Gas Cooking Equipment cannot be over stressed.. Proper performance of the equipment is dependent, in great part, on the compliance of the installation with the manufacturer’s specifications.. Installation must conform to local codes or, in the absence of local codes, with the National Fuel Code, ANSI

Z223..1, Natural Gas Installation Code, CAN/CGA-B149..1, or the Propane Installation Code, CAN/CGA-B149..2, as applicable..

Wall Clearance

This oven, single or stacked, must be installed with adequate clearance to combustible and non-combustible walls..

Sides:	1 inch [25 mm]
Back:	3 inches [76 mm] for gas ovens, and
	6 inches [152 mm] for electric ovens..

Garland recommends that a one inch clearance be maintained between this oven and any other cooking appliance..

Garland recommends that this oven not be installed with a broiler or open burner appliance immediately adjacent to the right side..

Each appliance shall be located with respect to building construction and other equipment so as to permit access to the appliance.. Such access and clearance may be necessary for servicing and cleaning..

GAS CONNECTIONS

The type of gas for which the oven is equipped is stamped on the data rating plate.. It is located inside the lower front trim cover.. Connect an oven stamped “NAT” to natural gas only.. Connect an oven stamped “PRO” to propane gas only..

If the oven is being installed into a new location, have gas authorities check the meter size and piping to assure the supply line has a sufficient amount of gas pressure to operate the oven..

If the oven is a replacement or additional appliance to an existing installation have gas authorities check the pressure to ensure the existing meter and pressure will supply the oven with no more than a 1/2” water column pressure drop..

Note: When checking the gas pressure make sure all other appliances on the same gas line are turned on..

A pressure regulator is supplied with Garland convection ovens.. The regulator pressure is preset to deliver the gas at the pressure shown on the rating plate.. Do not install an additional regulator where the unit connects to the gas supply unless the gas pressure exceeds the maximum recommended pressure..

The oven and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 PSI (3..45 kPa)..

The oven must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the supply system at test pressures equal to or less than1/2 PSI (3..45 kPa)..

Part # MPSM07 (03/24/08)

Prior to connecting to the building gas supply the lines should be purged of all metal filings, pipe thread compound or other debris..

The gas connection piping (3/4” for single ovens, 1” for stacked ovens), must be considered when planning the supply line.. Undersized gas supply lines may restrict the gas flow and affect performance.. If other gas appliances are supplied by the same supply line, it must be sized to carry

the combined volume required for all the appliances without causing a more than 1/2” pressure drop at the manifold of each appliance on line at full rate..

Recommended supply pressures are 7” ± 5% WC for natural gas (NAT) and 11” ± 5% WC for propane (PRO).. The inlet pressure for the supply line must not exceed 13..8”WC natural and 15”WC for propane..

Two ovens stacked may be supplied by a single gas line.. The minimum recommended size of a single supply line for two stacked ovens is 1 inch..

Assemble the gas pipes and fittings provided in the stacking kit as shown in the Figure 3 on page 7.. Use a pipe thread compound that is intended for use on propane gas piping..

Be sure to check for leaks before finalizing the installation.. Use appropriate solutions or detection devices..

Installations in which a flexible gas connection hose is used, require the supplied strain relief to be installed at the lower left rear corner of the base.. Install the strain relief in

accordance with applicable codes.. The strain relief must limit the movement of the oven to prevent unnecessary stress on the flexible connector..

Page 11

ELECTRICAL CONNECTIONS

A separate electrical connection must be supplied for each oven.. Connection to the electrical service must be grounded in accordance with local codes, or in the absence of local codes with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA C22..2, as applicable..

A strain relief for the power supply cord is required.. The installer must supply a cord bushing that meets local and national codes..

For 120VAC usage a cord and NEMA 5-15P plug is provided.. Garland recommends a separate 15 Amp service for each oven.. Ovens for 120V service are supplied with a three pronged plug for your protection against shock hazard and should be plugged directly into a properly grounded threeprong receptacle..

DO NOT CUT OR REMOVE THE GROUNDING PRONG FROM THE PLUG.

A wiring diagram is affixed to the rear of the oven and included in this booklet..

Part # MPSM07 (03/24/08)

WATER CONNECTIONS

It is the responsibility of the purchaser to install and maintain the water supply to the moisture+ oven.. Failure to provide satisfactory water quality to operate the oven properly

can cause damage to integral components and void your warranty..

This oven must be installed to comply with the applicable federal, state, or local plumbing codes..

Water supply connection to the moisture+ is made via a 1/8” NPTF fitting at the rear of the oven.. The ability to move the oven for service and cleaning may be a consideration when choosing the type of connection and supply line to be attached at this fitting..

The moisture+ water delivery system includes a water pressure regulator that has been pre-set to operate at 20 psi.. The water supply must maintain at least 20 psi and a flow rate of three gallons per minute for proper operation of the oven’s moisture injection system..

Water Quality Requirements

Garland recommends that the supply water be filtered before it enters the oven’s water delivery system.. This will extend the life of the oven and its water delivery system components by minimizing particles in typical tap water sources that cause scaling and build-up of mineral deposits..

The recommended minimum water quality standards, whether treated or pre-treated, and based on 10 hours of use per day, and daily cleaning../descaleing are as follows:

Total dissolved solids – less than 60 parts per million, total alkalinity – less than 20 parts per million, silica – less than 13 parts per million, chlorine – less than 30 parts per million and a pH Factor greater than 7..5..

Consult a local water treatment specialist for an on-site water analysis for recommendations concerning feed water treatment (if required), in order to remove or reduce harmful concentrations of minerals.. The use of highly mineralized water will cause more frequent cleaning and reduce operating efficiency.. The fact that a water supply is potable is not proof that it will be suitable for moisture mode operation.. Component failure/service related to poor water quality will not be covered under warranty..

Spray/Flex Hose W/Quick Disconnect

Your moisture+ oven may be equipped with the optional spray/flex hose assembly.. The spray/flex hose assembly is intended to assist in cleaning the oven.. The water pressure and velocity may vary, depending on the pressure and velocity of the water supply connected to the oven..

Drain

Your moisture+ oven has a gravity drain in the right rear corner of the oven cavity.. The drain pipe that exits the rear of the oven must be directed downward toward the floor, and should run directly to an open floor drain.. Garland provides an 1-1/2” male pipe adapter for connecting your drain lines.. Avoid using flexible hose that could sag or kink, allowing water to accumulate.. The drain must be vented.. This connection must be at least 1-1/2” (38..1 mm) in diameter and configured in accordance with local codes..

VENTILATION AND AIR SUPPLY

Proper ventilation is highly important for effective operation.. There are only two choices for properly venting an oven:

1) canopy hood, or, 2) direct venting.. The ideal method of venting a gas oven is through the use of a properly designed canopy hood.. The hood should extend beyond all sides of the oven 6 inches, (150 mm), and be installed at least 78 inches, (1950mm), from the floor..

A strong exhaust fan will create a vacuum in the room.. For exhaust system vents to work properly, exhaust and make-up air must be balanced.. For proper air balance, contact your local H..V..A..C.. contractor..

All gas burners and pilots need sufficient air to operate and large objects should not be placed in the rear or at the bottom of this oven which would obstruct the airflow

through the front covers.. Do not place objects over the oven vent exit..

Some localities require an electric oven to be installed under an exhaust hood.. Be sure to consult your local code inspector prior to operating any gas or electric oven..

IMPORTANT

ALL GAS BURNERS AND PILOTS NEED SUFFICIENT AIR TO OPERATE AND LARGE OBJECTS SHOULD NOT BE PLACED IN FRONT OF THIS OVEN, WHICH COULD OBSTRUCT THE AIRFLOW THROUGH THE FRONT.. OBJECTS SHOULD NOT BE PLACED ON MAIN TOP REAR OF THE OVEN WHILE IN USE.. THIS COULD OBSTRUCT THE VENTING SYSTEM OF THE OVEN’S FLUE PRODUCTS..

INSTALLATION OF A DIRECT VENT

When the installation of a canopy hood is impossible, the oven may be direct vented.. Before direct venting check you local codes on ventilation, in the absence of local codes refer to the National Fuel Code NFPA 54, ANSI Z223..1 (latest revision)..

If the oven is to be connected to a direct flue vent, it is necessary that a draft diverter be installed to ensure proper ventilation..

The draft diverter should be positioned on the main top of the oven and fastened with sheet metal screws provided.. All parts described above are available from the manufacturer..

Note: Each oven has been factory tested and adjusted prior to shipment.. It may be necessary to further adjust the oven as part of a proper installation.. Such adjustments are the responsibility of the installer.. Adjustments cannot be

considered defects in material or workmanship and they are not covered under the original equipment warranty..

DO NOT UNDERSIZE THE VENT PIPE! This can cause resistance to flow and impede good venting.. We suggest that if a horizontal run must be used it should rise no less than 1/4” (6..25mm) for each linear foot of run, and after a total of 180° of bends you should increase the size of stove pipe by 2”.. The flue should rise 2’ (60 cm) to 3’ (90 cm) above the roofline or 2’ (60cm) to 3’ (90cm) above any portion of a building within a horizontal distance of 10’ (3 m)..

Remove the lower front trim cover.. Drop the control panel and leak test all fittings and connections upstream from the service valve located on the redundant combination gas valve.. Should any gas leaks be detected turn OFF the main gas valve, correct the problem and begin the test again..

Remove the blanking plug from the manifold test spigot and connect a pressure test gauge..

Open the manual gas valve located behind the redundant combination gas valve..

Activate the control panel and set the oven to the desired temperature.. The burner will now ignite..

During installation there will be air in the gas line.. This air will have to bleed off before ignition can occur.. Wait five minutes after each attempt to bleed the air from the lines..

Turn on all appliances supplied by the same gas line and verify that the manifold pressure is 4..5”WC for natural gas or 10”WC for propane gas..

After the correct pressure has been verified, turn off the oven and remove the pressure gauge from the manifold pressure test spigot.. Re-install the blanking plug..

Check all fittings again.. Correct any leaks and begin the test again..

Replace all control panels, service panels and covers before operation..

All electronic ignition systems are supplied with a redundant gas valve.. Therefore, the oven is not supplied with an external pressure regulator..

To Conserve Energy:

Do not waste energy by leaving the controls at high temperature settings during idle periods.. Lower settings will keep the oven warm and ready for the next use period..
