Steam Injection (Optional Extra); Electrical Connections; Break-In Procedure - Garland 2000 Installation And Operation Manual

INSTALLATION Continued
DO NOT under any circumstances; connect the vent stack
of the oven directly to the flue pipe or a vent system . If this
is done, it seriously decreases the efficiency and will cause
uneven heating of the section . If an outside flue connection
must be made, a suitable hood placed 12" (05mm) above
the oven flue must be provided to prevent direct suction of
the air through the oven sections .

Steam Injection (Optional Extra)

Steam is often used for baking of hard rolls, French bread,
Vienna bread and other hard crust breads . The steam
provided inside the oven is a cloud of atmospheric steam or
water vapor .
One quarter broiler h .p . for each bake deck is required at
the steam inlet of the deck . It is important that the steam
provided to the oven is lower pressure ( lbs . To 5 lbs per
square inch), (2100 kg/m² to 500 kg/m²) and condensate
must be drained from the steam line before it enters the
oven .
The steam will be sufficiently saturated at this pressure to
provide the vapor cloud effect that is needed to cover the
top of the product .
When steam is required in the deck, it is recommended that
the steam valve at the deck is only open a half-turn for 
to 5 seconds . The time will be determined by the operator .
Allowing too much steam to enter the oven will produce a
soggy product .

Electrical Connections

The installation and connection should comply with current
codes . In Canada - The Canadian Electrical Code Part 1 and/or
local codes . In the U .S .A . - The National Electrical Code ASNA/
NFPA - current edition .
Before attempting the electrical connection, the rating
plate should be checked to ensure that the unit's electrical
characteristics and the supply characteristics agree .
The unit has been wired as specified on the factory order
and the rating plate is stamped with the information . If it is
necessary to change the phase, refer to the wiring diagram
attached to the main terminal block, or refer to the rating
plate .
Electrical connection may be made though the knockout at
the rear of bottom of the unit to the terminal block located
directly behind the switch panel on the main bottom . Hinge
switch panel open .
For the supply connection use suitable wire for 60° C .

Break-In Procedure

It is strongly recommended that the 2000 Series ovens
supplied with core plates be put through a break-in period
to eliminate possible warpage of the core plates caused by
moisture absorption .
This action need only be carried out once providing the
ovens are used daily, however, if the ovens are left idle for an
extended period of time allowing the core plates to absorb
moisture, the following procedure must be again carried out .
Turn the top and bottom heat selector switched to HI, set the
thermostat to 00°F (149°C) maximum and allow the oven to
operate (without any product in the oven), for approximately
8 hours .
