Read and understand this enre manual before operang this electric heater.
PRIOR TO INSTALLATION
1. Check for suspected damage to the heating blanket like rips, punctures, etc.
2. Verify surface to be heated is free from all sharp edges, weld splatter, rust, oil,
etc. Surface must be clean prior to installing heater.
3. Check that the desired placement of the blanket will not cause damage to the
blanket through impact shock, vibration, ambient temperature, or by
neighboring moving parts.
4. Confirm voltage / wattage rating of heater is appropriate for power supply
device or temperature controller. The heater is designed to work at a specific
voltage to heat properly. For additional information, contact your local
distributor or BriskHeat®.
5. Confirm blanket maximum exposure temperature rating is suitable for
environment. The temperature of the internal heating element may run up to
25% higher than the external surface of the blanket. Use extreme caution for
applications that require a process temperature near the maximum exposure
temperature ratings of the blanket.
 All Silicone rubber heating blanket except SRX exposure temperature
range: -60ºF to 450ºF (-51ºC to 232ºC)
 SRX exposure temperature range: -60ºF to 400ºF (-51ºC to 204ºC)
T3: 292ºF (145ºC) high limit thermostat
T4A: 158ºF (70ºC) high limit thermostat
6. Confirm all necessary installation hardware and tools are readily available.
Depending on the application, this may include:
Tools:
Wire strippers
Cleaning / prep supplies (varies based on what is being cleaned)
Medium to hard roller

MOUNTING YOUR HEATING BLANKET
Your silicone rubber heating blanket can be mounted on both flat and curved
surfaces. However, do not allow your heater to exceed the maximum “bend
radius”. The typical bend radius is approximately 2” (51mm). To determine the bend
radius, slowly bend the heater until it begins to crease or fold. The point prior to
creasing is the bend radius. Your heater may be more flexible in one direction than
the other, however, the heater should be installed with the wires exiting the
bottom if in an outdoor application.
Your heater can be attached to the surface using:
• Factory applied PSA (pressure sensitive adhesive)
• Factory supplied mechanical fasteners
• Factory supplied or recommended mechanical clamping devices
• High-temperature adhesive tape that will not damage the heater
• Thin layer of RTV
For all installations, regardless of adhesion method:
1. For proper temperature control, place the thermocouple, RTD, or other sensing
device, so that it touches the edge of the heating blanket.
 Sensor must be in close proximity to the heater to prevent
overheating.
 If heating blanket is installed on a vertical surface, place sensor
directly on lower edge of heating blanket since heat naturally rises.
 Sensor should be connected in accordance with instructions provided
with temperature controller.
 Secure with one strip of aluminum adhesive tape.
2. Ensure heater is in contact with the surface to be heated. If air gaps are
present, heat transfer will decrease and there is a potential to overheat the
heating blanket. Use a medium to hard roller to eliminate trapped pockets of air.
Do not wrap the heater over itself or allow it to contact a
second heater.
Hardware:
 Junction Box
 Wire Ties
 Mounting Hardware
 Temperature controller and sensor
 Silicone RTV
 Insulating material
 High-temperature adhesive tape
(part # AA2180)
 Plug if connecting heater to a
receptacle rather than hard wiring to
a temperature controller or junction
box

CONNECTING YOUR HEATING BLANKET TO A POWER
SOURCE
1. If your heating blanket does not have its own internal temperature control device,
it must be connected to an external control device. The heater must not be
operated without some form of temperature control.
 Your heater is designed to operate at a specific voltage ±10%. Refer to the label on
the heater for proper operating voltage and wattage information. Failure to operate
the heater at the specified rating could result in overheating of the heating blanket,
the surface being heated, or personal injury. Also note lower-than-rated voltage will
result in under-heating.
 All electrical connections must be made by qualified personnel and in accordance
with all applicable codes and regulations.
 SRX series: A NRTL (National Recognized Testing Laboratory) listed temperature
controller must be used to control the surface temperature of the blankets. The
controller must be approved for the area where it is located.
Installation of heater using factory supplied Pressure Sensitive Adhesive
(PSA):
3. Peel off the release film [Figure A] and then press the heater onto the surface of
the item being heated using a medium to hard rubber roller [Figure B]. Ensure
blanket is making intimate contact with the surface to be heated.
 The pressure sensitive adhesive will cure when the blanket is energized and
heat is generated. PSA generally cures in twenty minutes at 200ºF (93ºC) in a
68ºF (20ºC) ambient environment. The cure time will vary with temperature of
the blanket and surrounding ambient conditions. The higher the ambient
temperature and set-point of the blanket, the faster the cure time.
 The blanket may require a temporary method of attachment to secure the
heater until the PSA cures. Use a high-temperature adhesive tape (BriskHeat®
Part # AAT2180) to secure the heater.
 For larger heaters, press the heater onto the surface as the film is removed.
NOTE: BriskHeat® does not recommend allowing pressure sensitive adhesive to
cure at temperatures below 40ºF (4ºC).

2. Most heating blankets are available with an optional high-limit safety
thermostat to protect both the heater and the product being heated from
damage if the main controlling device fails. This option is especially
recommended for surfaces that are high risk for heat damage (e.g. plastic).
Contact factory for more details.
3. Ensure heater is protected by a properly rated circuit breaker or fuse.
4. Use of a ground fault circuit interrupter (GFCI) is highly recommended and
may be required according to local electric code.
5. Power lead wires should be connected to the power source (or temperature
control device) directly, through a junction box, or to a connector that is
mated to a receptacle connected to the power source. BriskHeat® Heating
Blankets are non-polarized, allowing either power lead wire to be connected
to the neutral or hot. The third wire (if applicable), designated by the color
green (or a green stripe), should be connected to ground. For three phase
installation, contact the factory.
6. SRX series: The conduit connection is 3/4” hub.
