Gas Information - ADC HB50 Installation & Operator's Manual

IMPORTANT: A strain relief must be used where the input
wiring enters the oven assembly.
Electrically Heated Models Only
The electrical input connections are made at the rear service
box located at the right upper section of the dryer. The ground
connection is made to a copper lug also provided in this
area. To gain access, remove rear service cover.
208-416 Volt Applications
The electrical input connections to the dryer are the
3-phase (3ø) power leads (L1, L2, L3, and sometimes
neutral) and ground. Single-phase (1ø) power for the control
circuit and for any single-phase (1ø) motors (if present) is
done internally to the dryer by the factory at the oven contactor.
The neutral will only be used on 4-wire service. This is
typical for 380-416V, 50 Hz.
440-480 Volt Applications
The electrical input connections to the dryer are made
through two different terminal blocks, one for the 3-phase
(3ø) power to supply the oven and one for the single-phase
(1ø) power for the motor and controls.
CAUTION: The dryer must be grounded. A ground lug has
been provided for this purpose.
Input connection wiring must be sized properly to handle
the dryer's current draw. This information is printed on the
dryer's data label.

Gas Information ______________________

It is your responsibility to have all plumbing connections,
materials, and workmanship conform to local and state
regulations or codes of the country of destination. In the
absence of such codes, all plumbing connections,
materials, and workmanship must conform to the applicable
local requirements. In the USA this is the National Fuel Gas
Code ANSI Z223.1-LATEST EDITION, or in Canada, the
Canadian Installation Codes CAN/CGA-B149.1-M91
(Natural Gas) or CAN/CGAB149.2-M91 (L.P. Gas) or LATEST
EDITION.
In Australia, the fuel gas code is AS 5601/AG 601, local
authority, gas, electricity, and any other relevant statutory
regulations.
It is important that gas pressure regulators meet applicable
pressure requirements, and that gas meters be rated for
the total amount of all the appliance Btu being supplied.
IMPORTANT: Failure to comply with these codes or
ordinances, and/or the requirements stipulated in this
manual, can result in personal injury and improper
operation of the dryer.
For ease of service, the individual gas supply line of each
dryer must have its own manual shutoff valve.
NOTE: The dryer must be isolated from the gas supply
piping system by closing its individual manual shutoff
valve during any pressure test of the gas supply system at
test pressures equal to or less than 1/2 psig (3.5 kPa) for
non-CE dryers or 50 mb for CE dryers.
Failure to isolate or disconnect the dryer from supply as
noted can cause irreparable damage to the gas valve,
voiding the warranty.
Warning
!
Fire or explosion could result from failure to
isolate or disconnect the gas supply as noted.
NOTE: Undersized gas piping will result in ignition
problems, slow drying, increased use of energy, and can
create a safety hazard.
The dryer must be connected to the type of heat/gas indicated
on the data label and pressure must be confirmed. If this
information does not agree with the type of gas available,
do not operate the dryer. Contact the reseller who sold the
dryer or contact the manufacturer.
The input ratings shown on the data label are for elevations
up to 2,000 feet (610 meters), unless elevation requirements
of over 2,000 feet (610 meters) were specified at the time
the dryer order was placed with the factory. The adjustment
or conversion of dryers in the field for elevations over 2,000
feet (610 meters) is made by changing each burner orifice.
If this conversion is necessary, contact the reseller who sold
the dryer or contact the manufacturer.
IMPORTANT: If connection to this appliance is made with
a flexible hose, it must be suitable for the appliance
category in accordance with national installation
regulations of the country of destination, and if in doubt
the installer must contact the supplier. The manufacturer
of this appliance does not recommend the use of flexible
gas supply line/hose. An external gas supply shutoff must
be provided.
