Installation 3

Venting:

WARNING

To avoid electrocuting yourself or damaging

the Thermoglaze, never allow water, steam,

cleaning solution, or other liquid to enter the

electrical panels or connections

Local codes prevail. The authorities having
jurisdiction are stated in NFPA 96-1994
regarding requirements for the Thermoglaze.

Building Layouts:

Electrical:

Model Dimensions Power Requirements

88"L x 40W x

TG21586

Make sure that the power requirements of the
Thermoglaze, shown on the data plate, match
your power source.

Only plug in to power source that matches the
required voltage and current for the
Thermoglaze. (The Thermoglaze unit TG50
comes standard with a Hubbel 360P6W plug that
needs a 360C6W socket or equivalent for
electrical current.

Thermoglaze must be electrically grounded and
connected in compliance with the National
Electrical Code, ANSI-NFPA 70, and applicable
municipal building codes.

Specification sheets and AutoCAD drawings for
use in developing architectural drawings can be
provided by request. Please call your Belshaw
Bros., Inc. representative for help in defining
your requirements.

Do not apply electrical power to the system until
the assembly has been completed. See Section 4
for the assembly of the Thermoglaze.

Assembly 4

Clean all parts with mild soap and water and

let dry before assembly and applying

electrical power to the equipment.

The Thermoglaze unit is design for ease of
assembly and use. The system is crated in a
manner so there are few pieces to put together
once the Thermoglaze is in place for production.

After unpacking the system per the uncrating
instructions, 2 items need to be placed on the
Thermoglaze to finish assembly, the glaze trough
and the heat shield. First, the Glaze trough slips
into the 2 holes on either side of the drain tray
with the waterfall headed toward the oven. See

figure 4-1 and 4-4 for help setting the trough in
place. After the trough is in place attach the glaze
hose to the trough by pushing it in the hose
mount in the center of the trough. Second is the
Heat Shield over the oven portion of the
Thermoglaze. Slip it over the oven using the
handles provided until the guard locks over the
back of the oven. See figure 4-1 for a photo of
the location of the heat shield.

To help familiarize you with your Thermoglaze,
please study the following photographs:

ready light is on. See Figure 5-1.)

Figure 5-1. Oven Ready Light.

• Turn on the Thermolizer and heat for 30

minutes to allow it to reach operating
temperature. See Thermolizer manual for
more operating instructions.

• Load glaze reservoir with 40 pounds (one

large bucket) of glaze and turn on the glaze
pump.

using the on switch located on the main
control panel.

• After the donuts are thawed, place a screen of

donuts from Thermolizer box to the infeed
end of the Thermoglaze conveyor and allow
the screen to travel through the oven and
glazer. This takes approximately 3 minutes.

• When the screen of donuts is through the

glazer and stopped forward travel, place the
glazed product on a rack for cooling using
the 2 delrin tray grips provided with the unit.

WARNING

To avoid burning yourself, never touch the

Thermoglaze unit, conveyor, or interior of the

oven while the machine is in use.

WARNING

Thoroughly clean and dry the floor if water or

other materials are spilled. Materials spilled

on the floor may cause serious injury and loss

of life.

• To swing the glaze trough back, turn off

glaze pump, lift up on the mount slightly and
rotate to the trough to the rear. (Optional
Equipment) See Figure 4-3.

WARNING

Do not operate glazer without glaze or water
in the pump. Doing so may cause permanent

damage to the pump.

• After the donuts have been in the

Thermolizer for at least 20 minutes (60
minutes for filled product), turn on glazer
