Please carefully follow the instructions in this manual to prevent personal injury or property loss.
The steps listed as:
WARNINGS Contains information critical to the safe installation and operation of the TK unit.
WARRANTY REQUIREMENT must be strictly followed to qualify for product warranty.
Warranty will be void if not followed.
IMPORTANT Are notes and insights to help ensure product satisfaction and serviceability.
WARNING: REMOTE CONTROL USE: To prevent accidental start-up from unwanted RF
signals it is the responsibility of the end user to turn off power to electric outlet for the remote
control receiver when the TK is not in use. This should be done via wall switch or breaker.
WARNING: We suggest that our products be installed and serviced by professionals who are
certified in the U.S. by NFI (National Fireplace Institute) or in Canada by WETT (Wood Energy
Technical Training). Installer must follow all instructions carefully to ensure proper
performance and safety. Hearth Products Controls Company is not responsible for your actions.
WARNING: It is the responsibility of the installer to follow all local and state codes concerning the
installation and operation of the TK.
WARNING: Confirm your gas type matches the requirement for the TK- see label on Bottom of the TK.
Gas Pressure: This should be checked prior to use and installaion:
● Natural Gas Fire Pit:
Supply Pressure: Minimum: 5.0” W.C.; Maximum: 7.0” W.C.
● LP Gas:
Supply Pressure: Minimum: 10.0” W.C.; Maximum: 14.0” W.C.

2) Selecting the Location
WARNING: The TK is designed for outdoor use only. HEARTH PRODUCTS CONTROLS CO. must be
notified of any other use.
WARNING: The TK creates very high temperatures-it is very important that combustibles and people are
kept at safe distances.
WARNING: For installation of the 24vac powered TK, it is required to install a wall switch or breaker for
the TK electrical outlet away from the TK to prevent unwanted ignition of the fire pit.
WARNING: The TK location must accommodate a gas shut off in an accessible area.
•The gas line should be a minimum of 1/2” or larger based on the number of TK’s or other fire
features and the distance from the energy source to the TK. Consult your local professional for
proper gas line sizing.
•To enjoy your TK, select a location that allows for sufficient clearance from combustible
materials.
•Choose a location that allows easy access for installation and maintenance of the TK. Make sure
that trees and shrubbery are well clear around and above the TK.
•Pick a location that allows sufficient horizontal room to enjoy the TK while allowing a safe
distance from the heat and flame.
•The TK is designed to be installed on a post. It is recommended that the TK flame is a minimum
of 84” off the ground. This is a guideline. Installers should follow local code.
•The unit needs to be installed in a manner that ensures that pedestrian traffic cannot get closer than
a 48” perimeter around the flame.
•Select a location where the TK can be attended during operation. Never leave an operating TK
unattended or by someone not familiar with its operation or emergency shut off locations.
•Wooden or solid surfaces such as granite or marble must be located far enough away that they do
not reach a temperature of more than 100 degrees F plus ambient air temperature.
Example: If surrounding air temperature is 70, the wood surface temperature must stay at
or below 170 degrees F.
•TK Clearance:
TK Clearances
Sides Surrounding TK 48”
Above TK 96”
3) Site Preparation
WARNING: Ensure sufficient clearance from all combustibles and pedestrian traffic as outlined in
“Selecting The Location”.
WARNING: Class II, 24VAC, 4 amps (14 gauge wire) must be supplied to the TK head and able to be
switched on and off from a remote location to allows for easy access or emergency. POWER MUST
BE TURNED OFF WHEN NOT IN USE.
IMPORTANT: Design site so the gas connection and 24vac electric supply are accessible after installation
for maintenance.
IMPORTANT: If flex hose is used care must be taken not to drop the hose down the post. This can be
especially problematic if the post is buried in concrete.
IMPORTANT: It is not recommended to mortar the post in place. This may make servicing the unit
difficult. If the post will be mortared in place it may be advantageous to run solid pipe through the post to
prevent accidentally dropping the flex hose down the post.
IMPORTANT: Determine installation method from Figure 1 or plan another method following the
guidelines of this manual.

4) TK Installation
WARNING: Confirm this appliance is built for the gas used – natural gas or LP. Do not used natural gas
appliance with LP or LP appliance with natural gas. Refer to label on this appliance.
WARNING: Always use proper materials and construction for gas supply, power, and post. Select
materials that are non-combustible. .
WARRANTY REQUIREMENT: The TK should be supported by a 3” Post of sufficient strength to
support the TK head and withstand winds..
WARRANTY REQUIREMENT: Do not change the TK configuration in any way.
IMPORTANT: If method 3 or 4 is used check PVC/Post fit as desired before mortaring PVC in place.
Installation
1. Ensure gas and power to the TK location are shut off.
2. Cut a 3/8” by 2-1/4” slot in the top of the post for the needle valve stem. (Image 3&4, pg 6)
3. Run Flex Hose through post (if used).
4. Run power wire though post.
5. Connect ¼” Male end of flex hose to TK Head. Avoid sharp bends with flex hose to prevent whistling.
6. Turn on main gas supply and check all fittings in and around TK for leaks using a leak reactant,
leak detector or soapy water. If leaks are found, shut off gas supply repair leaks and retest.
7. Connect 24VAC to wires from bottom of TK.
a. White is common, Black is positive.
8. Set post in place and secure.
9. Secure Post by chosen installation method.
a. For method 3 & 4 mortar the PVC sleeve in place.
b. Choose inside or out sleeve and ensure your PVC fits your post prior to mortaring in place
•Slide post over or inside of PVC Sleeve and back fill.
oAllows for the post to be removed for service.
10. Ensure finished installation is sturdy.
a. For the 3” PVC a bead of silicone at the post/PVC seam can be applied to add stability if needed.

5) TK Operation
WARNING: Before use test all gas connections for leaks. Do not use TK if there is any evidence of leaking
gas. If leaking gas is suspected turn off the main gas supply and repair.
WARNING: When TK is not in operation power must be turned off via wall switch or breaker.
WARNING: Leaves, sticks, wood, paper, clothing, food material, should always be kept away from the TK.
Make sure that there is no vegetation or other objects over the top or sides of the TK that could ignite or
interfere with safe and proper operation.
IMPORTANT: As a safety feature if power to TK is turned “OFF” then immediately turned back “ON”, the
system will go into lockout mode.To reset, turn “OFF” power then back “ON” again.
Initial Start-up: Several “on/off” cycles may be necessary to purge air in gas lines after system
installation. TK will lockout after 15 attempts to light pilot: Please power OFF then ON to restart.
TK START UP
1. STOP! Read the safety information on “What to Do If Smell Gas” (Pg. 1).
2. Confirm there is no debris in TK (as mentioned in warnings).
3. Turn “ON” electrical power and gas to fire pit.
4. Using wall switch or remote, turn “ON” TK- this may take several cycles to
purge any air.
5. To reset after lockout, power unit down then restart.
6. Once TK has ignited, DO NOT leave unattended.
Sequence of Operation:
1. The hot wire igniter will be powered (glow red) for 5 seconds before valve opens.
2. The hot wire igniter will only be powered the initial 15 seconds of the 60 second pilot cycle. This
sequence will repeat up to 15 times (~15 minutes) before going into lockout. To reset, turn “OFF” power
then back “ON” again.
3. Flame will ignite and warm thermocouple- it may take 30 seconds at times for thermocouple to get hot.
If thermocouple is not hot in 60 seconds, system will shutdown then go back to Step 1.
4. Once thermocouple is hot, main valve will open allowing main burner to ignite.
5. If flame is blown out at anytime, system will shutdown, then automatically restart (Step 1).
TK SHUTDOWN
1. Turn “OFF” TK using remote control or wall switch.
IMPORTANT: REMOTE CONTROL USE: YOU MUST ALSO TURN OFF POWER TO
REMOTE CONTROL SYSTEM TO PREVENT ACCIDENTAL START.

b. Use a non abrasive soap to prevent scratching the Kano sleeve.
3) Cleaning of thermocouple: A build up of soot on the thermocouple will result in the TK shutting off
frequently and possibly going into lock out.
f) With a small soft bristle brush clean the thermocouple and burner.
a. Be careful not to damage the igniter.
