Gas Supply Requirements; Electrical Requirements - Whirlpool COMMERCIAL DRYERS Installation Instructions Manual

GAS DRYER MODELS
This appliance is suitable for mobile home installa-
tions. The installation of the dryer must conform
to the Manufactured Home Construction and Safety
Standard, Title 24 CFR, Part 32-80 [formerly the
Federal Standard for Mobile Home Construction
and Safety, Title 24, HUD (Part 280), 19751.
For mobile home use, this appliance MUST be
fastened to the floor and MUST be exhausted to
the outside. Order Mobile Home Installation Kit
No. 346765 from your Whirlpool Dealer. Kit
includes the necessary fastening hardware and
detailed installation instructions. Exhaust system
hardware is also available through your Whirlpool
Dealer.
GAS SUPPLY REQUIREMENTS
OBSERVE ALL GOVERNING CODES AND ORDINANCES
This installation must conform with American
National Standard, National Fuel Gas Code ANSI
2223.1 - 1980, and local codes and ordinances.
Input ratings shown on the rating plate (serial tag)
are for elevations up to 2,000 feet. For elevations
above 2,000 feet, ratings should be reduced at a rate
of 4% for each 1,000 feet above sea level.
1. First make certain that this dryer is equipped
with the correct orifices for the particular type of
gas used. Check local utility for type of gas and
BTU rating.
All gas dryers are manufactured with natural gas
(Type 1) burner assemblies. In areas using mixed
gas (Type 2) or manufactured gas (Type 3) it is
necessary to use replacement orifices as specified
for the main burner. Refer to service manual charts
for determining correct orifice sizes.
When converting the burner assembly to either
butane or propane (LP) gas, a special conversion
kit is required. Refer to service manual to determine
conversion kit for particular gas usage.
2. Provide a gas supply line of l/z" pipe to the dryer
location. (If dryer is to be used on LP gas, Ye"
approved copper tubing may be used.) If the total
length of the supply line is more than 20 feet, use
larger pipe. Pipe thread compounds suitable for the
type gas should be used.
3. The supply line should be equipped with a shut-
off valve. This valve should be located in the same
room as the dryer and should be in a location that
allows ease of opening and closing.
4. If the dryer is installed in a confined area such
as a bathroom or closet, consideration should be
given to provide enough air for combustion and
ventilation. (Check local codes and ordinances.)
5. Wall spacings see page 6.
6. A l/8 inch NPT plugged tapping, accessible for
test gage connection,must be installed immediately
upstream of the gas supply connection to the dryer.
7. The dryer and its individual shutoff valve must
be disconnected from the gas supply piping sytem
during any pressure testing of that system at test
pressures in excess of l/2 psig (3.45 kPa). The
dryer must be isolated from the gas supply piping
system by closing its individual manual shutoff
valve during any pressure testing of the gas
supply
piping sytem at test pressures equal to or less than
l/2 psig (3.45 kPa).
8. If local codes permit, it is recommended that
flexible metal tubing be used for connecting the
appliance to the gas supply line. (The gas feed
pipe, which extends through the lower rear of the
appliance is provided with a Ye" male pipe thread.)
9. If rigid pipe is used as a gas supply line, a
combination of pipe fittings must be used to obtain
an in-line connection to the dryer.
lO.Make sure the lower edges of the cabinet, plus
the back and bottom sides of the dryer are free of
obstructions to permit adequate clearance of air
openings for combustion air.
1 l.For ease of installation, operation and servicing
(if ever needed) adequate space should be provided
around the dryer.
12.The wiring diagram is located inside the lower
access panel. See page 3 for instructions on opening
of the access panel.
ELECTRICAL REQUIREMENTS
OBSERVE ALL GOVERNING CODES AND ORDINANCES
A 120 Volt, 60 Hz, AC only, 15 Ampere fused
electrical supply is required (time delay fuse or
circuit breaker is recommended). It is recommended
that a separate circuit serving only this appliance
be provided. DO NOT use an extension cord.
Electrical ground is required on this appliance.
RECOMMENDED GROUNDING METHOD
DO NOT, UNDER ANY CIRCUMSTANCES, REMOVE THE
POWER SUPPLY CORD GROUND PRONG.
For your personal safety, this appliance must be
grounded. This appliance is equipped with a power
supply cord having a 3-prong grounding plug.
To minimize possible shock hazard, the cord must
be plugged into a mating 3-prong grounding type
wall receptacle, grounded in accordance with the
National Electrical Code ANSI/NFPA No. 70-1984
and local codes and ordinances. If a mating wall re-
ceptacle is not available, it is the personal respond-
sibility and obligation of the customer to have a
properly grounded 3-prong wall receptacle installed
by a qualified electrician. See Figure 3.
For added personal safety, using the clamp and
green colored copper wire furnished, connect this
separate ground wire (#18 minimum) from the
external ground connector on the back of the appli-
ance to a grounded cold water pipe.* See Figure 4.
