START UP & SHUT DOWN INSTRUCTIONS
Connecting the Heater to the Thermostat & Power
1. You will need two 12-gauge extension cords to complete steps 2 - 6.
2. The heater has a short black power cord coming off of it. The first step in
connecting the thermostat to the heater is to plug the short black power cord
coming off the heater into the female end of one 12-gauge extension cord. You'll
then take the male end of that same extension cord and plug it into the female
receptacle labeled "heating" (see pic. below) on the Inkbird ITC-308 Wifi
thermostat.
3. Next, you'll take the male end of the long black power cord coming off of the
thermostat and plug it into the female end of the second 12-gauge extension
cord.
4. The final step is to plug the male end of the same extension from step 3 into a
120 volt outlet with a 15 amp breaker or higher.
5. Your heater and thermostat should now be fully powered.
6. Return to the heater and confirm that the green indicator light is illuminated. In
the event it is red only (ungrounded), or both red and green lights are illuminated
(reverse polarity), you will need to switch outlets. Failure to do so may result in
damage to the control board of the heater.
5

Attach Duct Adapter and Duct
7. Next, connect the duct adapter to the heater by inserting the two small hooks on
the adapter into the two small slots on the side of the heater. Attach the mylar
duct to the duct adapter with the provided metal strap.
8. Run the mylar ducting into the space. It is recommended that flooring is protected
by putting some form of insulation, such as Reflectix or a similar product, under
the mylar duct to protect the flooring from potential heat damage.
Connecting Gas Lines
9. Next, you will connect your propane cylinders using the supplied manifold
regulator assembly. Connect the brass POL fitting from the smaller gas line(s) to
the propane tank. The connection is reverse thread, and will need to be turned
counterclockwise to thread into the tank. Note: Tanks should be placed a
minimum of 10’ away from the heater, and 10 feet from the structure.
6

10.Connect the 50’ gas hose to the machine by sliding the female quick connect
pictured below over the male connection on the heater.
11. Insert the male connection to the female quick connect on the regulator.
12.Return to the propane tank/s & slowly open the valve on the tank to prevent the
safety fitting from locking out gas flow to the gas line.
7

13. Slowly open the shutoff valves on all connected tanks to release the flow of gas
through the regulator and to the heater. Make sure the shutoff valve handle is
parallel with the gas hose.
Turning the Heater On
14.Flip the fan switch up to the “on” position, then flip the burner switch to the “on”
position.
15.Lastly, be sure to place the thermostat (mentioned in steps 2-3) all the way
inside the treatment space, far enough away from the heater and duct, so that
the thermostat can monitor the temperature of your treatment area and relay that
information back to the heater.
Turning the Heater Off
1. Close the fuel supply (propane tank/s).
2. Move the “BURNER” switch to the “OFF” position.
3. Wait 2-3 minutes and move the “FAN” to the “OFF” position.
4. Disconnect from the fuel supply.

SAFETY
1. A fresh air source is REQUIRED when operating the unit inside the treatment space.
Be sure to have an adequate air source by connecting a section of ducting 8” in
diameter or larger, to the rear grated panel of the machine and running the connected
ducting outside of the structure. The machine will pull in fresh air to help ensure
adequate ventilation. Below is an example of a connection where a 12” diameter flange
from Lowe’s is screwed to the back of the machine. The duct is connected to the flange,
then runs to the outside through a window to draw in fresh air to help avoid elevated CO
(Carbon Monoxide) levels. You can also use spring clamps to clip the duct to the back of
the machine.
2. Check all gas hoses and connections for leaks prior to starting the heat. Fill a small
spray bottle with a soapy solution and spray the connections to assist with detection,
DO NOT use the machine if any leaks are detected.
3. Place propane outside of the structure, and at least 10 feet away from the heater.
4. Do not connect the machine to an ungrounded extension cord or outlet.
5. Do not place the heater discharge within 5 feet of any objects.
6. Do not place heater/duct against objects, or blowing directly at objects that can be
damaged by high heat.
7. Even though the heater is certified for indoor and unattended use, we strongly
recommend continuously monitoring the system and structure at ALL times.

FAQS
1. Can the Delta series heaters be placed inside the treatment space?
● Yes, however, a fresh air source is REQUIRED if operating the unit inside
the treatment space. Make sure to have an adequate air source by
connecting a section of ducting 8” in diameter or larger to the rear grated
panel of the machine and run the connected ducting outside of the
structure. The machine will pull in fresh air to help ensure adequate
ventilation.
●DO NOT OPERATE THE HEATER IN A CLOSED OR CONFINED
SPACE.
2. What items do I need to purchase that are not included with the heater?
● Propane tanks (Common Suppliers are Tractor Supply, Menards, Lowe’s,
Home Depot, and most local hardware stores.)
● Two 12-gauge extension cords, one for the heater, and one for the
thermostat
3. What size propane tanks do I need to use with my Delta 175 Propane Bed
Bug Heater heater?
● 3 thirty-pound tanks or greater
4. How many square feet does the Delta 175 Propane Bed Bug Heater treat in
standard conditions?
● 900 sq. ft.
NOTE:If the structure has exposed concrete, ceilings exceeding 8’ height, or outdoor
temperatures below 30 degrees F, capacity may be reduced.
5. How do I power the heater & connect the high temp thermostat?
a. The heater has a short black power cord coming off of it. The first step in
connecting the thermostat to the heater is to plug the short black power
cord coming off the heater into the female end of one of the extension
cords. You'll then take the male end of that same extension cord and plug
it into the female receptacle labeled "heating" on the Inkbird ITC-308 Wifi
12

thermostat. DO NOT attempt to plug into the “thermostat” connection on
the heater itself.
b. Next, you'll take male end of the long black power cord coming off of the
thermostat and plug that into the female end of the second extension cord.
c. The final step is to plug the male end of the same extension from step 2
into a wall outlet. Your heater and thermostat should now be fully powered.
Turn the blower on and flip the burner switch to the “MANUAL” setting,
otherwise the heater will not turn on. Note: Be sure to place the
thermostat all the way inside the treatment space, far enough away from
the heater and duct, so that the thermostat can monitor the temperature of
your treatment area and relay that information back to the heater.
6. How much time is required to perform a heat treatment?
● Treatment times can vary depending on factors such as space size,
clutter, and structural materials. For example, a 500 square foot room with
two concrete walls will take an average of 20-30% longer to achieve “kill
temperature” than a room with drywall only. Our systems are sized to treat
a space within a standard 8 hour day. Our recommendation is to achieve a
space temperature range of 125 - 140 degrees and hold for a minimum of
4 hours to ensure that the wall voids, furniture, and other interstitial spaces
achieve “kill temperatures”.
7. Do I need to cool down my treatment space after I’ve completed the heat
treatment?
●If occupants plan to reenter the dwelling after the heat treatment is
completed, you will need to cool the structure down to a minimum of 85
degrees F prior to returning occupants into the structure.
●Place fans pulling air from outside of the structure blowing in to assist. Do
not attempt to operate the air conditioning to assist until the temperature is
below 105 degrees F in the structure, as the blower motor may get
damaged.
