Maintenance - Delfield 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.

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.

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.
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.
160°F to 180°F
140°F to 160°F
Do not use a hose or pressure washer on these
units. The water will damage the electrical and
gas components.
