INSTINCT NATURAL TO PROPANE CONVERSION INSTRUCTIONS
1. Preliminary Instructions:
1. Verify that the \venturi replacement kit is correct
for the model of boiler. See page 1.
2. Turn o electrical power supply to the boiler.
3. Close the manual gas shut o valve to the unit.
4. Remove the front panel of the Instinct by removing
the screw along the bottom edge of the unit. Pull
the bottom of the panel forward and then lift to re-
move the front panel from the unit.
5. Using a voltmeter ensure there is no electrical pow-
er to the boiler by checking for power on the boil-
er’s high voltage terminals L and N.
WARNING
!
ELECTRICAL SHOCK HAZARD
Ensure power to the boiler has been disconnected pri-
or to servicing the unit.
2. Install the Acoustic Foam (supplied);
1. Cut a 7" length of 3" diameter air inlet piping.
2. Insert the 7" pipe into the air inlet adaptor.
NOTICE
The the INSTINCT boiler has a length of acoustic foam al-
ready installed in the air inlet adaptor. DO NOT remove this
3. Insert the length of acoustic foam (supplied),
into the 7" pipe length.
4. Use either a straight coupling or elbow to con-
tinue the air inlet installation. Refer to the Vent
Supplement for full details on the installation of
air and vent pipes.

3. Removal of Natural Gas Venturi
1. Remove the silicone tube from the air inlet elbow,
then remove the air inlet elbow.
2. Rotate the venturi interface approximately 60°
clockwise to release the clamping mechanism and
remove the venturi interface.
3. Remove the gas valve to venturi pipe by loosening
the nuts at both ends of the pipe with an adjust-
able wrench.
NOTICE
There are gaskets at both ends of the gas valve to venturi
pipe. These gaskets must be reinstalled along with the pipe.
Use care not to damage the gaskets.
4. Using a 10 mm socket and ratchet, remove the
three (3) bolts securing the venturi to the fan as-
sembly and remove the natural gas venturi from
the unit, making sure not to damage the blower
O-ring gasket.
4. Install the propane venturi
1. Verify the following when aligning the propane
venturi:
1. The UP arrow on the plastic housing is pointing
upward.
2. The threaded connection for the gas piping is in
the correct orientation for re-tting the gas pipe.

INSTINCT NATURAL TO PROPANE CONVERSION INSTRUCTIONS
WARNING
!
Failure to retain the O-ring gasket between the ventu-
ri and the blower will cause an improper seal resulting
in a potential risk of a gas leak. A gas leak can result in
substantial property damage, serious injury, or death.
WARNING
!
Ensure the proper venturi for the model is installed
per Table 1. Failure to comply will aect input rate
and combustion of the boiler which can result in sub-
stantial property damage, serious injury, or death.
NOTICE
Do not use adhesive on any gaskets or O-rings during the re-
assembly process.
1. Using a 10 mm socket and ratchet, reinstall the
three (3) bolts securing the venturi to the fan as-
sembly
2. Reassemble the gas valve to venturi pipe to the
gas valve and venturi taking care to ensure that the
gaskets are seated properly before tightening the
nut.
3. Install the venturi interface on the venturi and ro-
tate counterclockwise until locked into place.
4. Install the air inlet elbow then attach the silicone
tube.
WARNING
!
Failure to properly install the air inlet elbow and at-
tach the silicone tube can aect combustion of the
boiler which can result in substantial property dam-
age, serious injury, or death.
5. Open the manual gas shut o valve to the unit.
Before placing the boiler back into operation, test
all gas connections for leaks and repair if leaks are
found.
WARNING
!
Do not check for gas leaks with an open ame. Use a
bubble test. Failure to test for gas leaks can result in
substantial property damage, serious injury, or death.
6. Attach the propane conversion label to the gas
valve and the propane conversion rating label next
to the existing rating label
7. Enter the propane (LP) appliance code from the
propane rating label supplied in the conversion kit:
1. Press and hold the UP and DOWN buttons to-
gether see Fig. 5.
Fig. 5: CTRLMax Navigation Control

the LEFT and RIGHT buttons to select a digit and
the UP and DOWN buttons to change the digit.
Press the center button to enter the access code.
3. With the CH/DHW Settings icon highlighted,
press the center button.
4. Press the DOWN button to highlight the Boiler
Settings icon then press the center button.
5. Scroll down to highlight Appliance Setting then
press the center button.
6. Enter the propane (LP) appliance code from the
rating label by using the LEFT and RIGHT buttons
to select a character and the UP and DOWN but-
tons to change the character. Press the center
button to enter the appliance code.

5. Combustion Test and Adjustments
NOTICE
The installer MUST perform a complete combustion check
to ensure the following combustion levels are met at high
and low input ring rates and the burner is operating at op-
timum conditions.
WARNING
!
The combustion testing and adjustments must be per-
formed by a qualied installer, service agency or the
gas supplier. All combustion measurements must be
performed with calibrated equipment to ensure prop-
er readings and accuracy.
WARNING
!
Failure to perform a complete combustion test at both
high and low input rates may result in incomplete
combustion and the production of carbon monoxide,
which can cause severe personal injury, death or sub-
stantial property damage.
1. Touch simultaneously on the up and down soft
keys for 3 seconds to access the functions for the
installer. See Fig. 5.
2. Enter the installer access code “054” by using the
LEFT and RIGHT buttons to select a digit and the UP
and DOWN buttons to change the digit. Press the
CENTER button to enter the access code.

4. Press the CENTER button while the FAN icon is
highlighted to manually re the burner and power
the CH circulator. See Fig. 6
NOTICE
An adequate CH load must be present to dissipate the heat
generated during the combustion test. If an adequate CH load
is not available, an indirect water heater can be used to dis-
sipate the heat by creating a DHW call which will enable the
DHW circulator.
5. Press the RIGHT button to adjust the ring rate to
100% (high re). Hold down the RIGHT button to
rapidly increase the ring rate.
6. If the combustion levels during high re are outside
the recommended combustion settings (see Table 1),
adjust the THROTTLE SCREW (see Fig. 7) using a at-
blade screwdriver as follows:
Counter-clockwise adjustment of the THROTTLE
SCREW at High Fire (100% ring rate):
O2decreases and CO2 increases
Clockwise adjustment of the THROTTLE SCREW at
High Fire (100% ring rate):
O2increases and CO2decreases
7. Once the combustion level is set at high re, manu-
ally place the boiler into low re mode by pressing
the LEFT button to adjust ring rate down to 1% (low
re).
8. If the combustion level (O2or CO2) during low re is
not are outside the recommended combustion set-
tings in Table 1 contact Triangle Tube Technical Sup-
port.
9. Press the CENTER button while the fan icon is high-
lighted to shutdown the burner.
10. Press the LEFT or RIGHT button to highlight the home
screen icon to exit the service mode.
11. Replace the front panel and put the boiler back into
operation.
