Delfield 48000 Series Maintenance, Lighting the pilot, Filling the well and pre-heating

F14 AND 48000 Series Service and Installation Manual

OPERATION: F14GW SERIES (GAS)

Gas connection

Only qualified and trained personnel should attempt to connect the gas. Wear a face shield during this procedure. Delfield is not responsible for injuries resulting from attempts connect the gas.

You must supply the necessary connection. A pressure regulated, 1/2” FPT. 20,000 BTU gas supply is required. A gas regulator is supplied installed.

Be sure the connection is made to maintain flow through the safety valve in the direction indicated by the arrow stamped on the valve case. See the gas burner assembly diagram on page 6.

After installation, check for leaks using a soap solution. Mix some water with dish or other soap and supply a small amount to the connection. If bubbles appear, the connection is not correct and must be reinstalled before operating the unit.

The pilot valve supplied is sized for use with natural gas. If LP gas is to be used, the pilot fitting must be changed from the standard .021” orifice to a .011” orifice. This orifice is supplied in a plastic pouch attached to the plate shelf.

Gas hot food tables must be operated with water in the well. Dry operation of this unit will cause distortion of the well or other serious damage.

Steam can cause serious burns. Always wear some type of protective covering on your hands and arms when removing lids or pans from the unit. Lift the lid or pan in a way that will direct escaping steam away from your face and body.

Never place food directly into the empty well, always use pans. Never operate burners without water in the well.

Always place covers on pans when not serving to prevent food from drying out and to reduce your operating cost.

For most efficient operation, when empty, keep covered insets in each well during preheating and when the well is not in use.

Lighting the pilot

Only qualified and trained personnel should attempt to light the pilot. Wear a face shield during this procedure. Delfield is not responsible for injuries resulting from attempts to light the pilot.

1)Open the gas valve supplying fuel to the hot food table

2)Push down the reset button on the pilot valve, which is located behind the control panel, and light

the pilot.

3)Continue to hold down the reset button for 30 to 45 seconds or until the pilot continues to burn when the button is released.

4)During the reset cycle, gas will flow to both the main and pilot burners.

5)If the pilot is not lit after steps 1-4 have been

completed, close the gas valve and wait for at least 5 minutes before attempting to light the pilot again. This should allow any excess gas in the air around the unit to dissipate. If you are using LP gas, wait at least 15 minutes; any excess gas will “fall” to the floor and will require more time to dissipate.

Filling the well and pre-heating

1)With the drain cock closed, fill the well until approximately a four inch depth is obtained. More water may be required if shallow depth pans are used. Always pour water in the well before pre-

heating. For quicker pre-heating use hot water to fill the well.

2)Turn the gas control knob 1/4 turn counterclockwise and wait for the water to preheat. Then set the control to your desired serving temperature.

Temperature

Water in wells	160°F to 180°F
Product in pans	140°F to 160°F

MAINTENANCE

The exterior can be cleaned using mild soap and warm water. If this is not sufficient try ammonia and water or a non-abrasive liquid cleaner. When cleaning the exterior, always rub with the grain of the stainless steel to avoid marring the finish. Do not use an abrasive cleaner because it will scratch the stainless steel. A stainless steel cleaner or polish may be used to eliminate water spotting and fingerprints and bring out the finish of the exterior. The interior of the food wells should be cleaned daily with a

non-abrasive cleaner and non-abrasive pad. If necessary, a mild abrasive may be used on the interior of the pans only. Hard water stains and lime scaling may require a special cleaning product. Never use steel wool.

Do not use a hose or pressure washer on these units. The water will damage the electrical and gas components.
