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.

2. 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.
3. Install the propane venturi

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.

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 affect 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.
2. Using a 10 mm socket and ratchet, reinstall the
three (3) bolts securing the venturi to the fan as-
sembly
3. 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.
4. Install the venturi interface on the venturi and ro-
tate counterclockwise until locked into place.
5. 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 affect combustion of the
boiler which can result in substantial property dam-
age, serious injury, or death.
6. 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 flame. Use a
bubble test. Failure to test for gas leaks can result in
substantial property damage, serious injury, or death.
7. Attach the propane conversion label to the gas
valve and the propane conversion rating label next
to the existing rating label
8. Enter the propane (LP) appliance code from the rat-
ing label:
1. Press and hold the UP and DOWN buttons to-
gether see Fig. 4.

4. 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 qualified 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. 4.
2. Enter the installer access code “054” by using the
LEFT and RIGHT buttons to select a digit and the UP

4. Press the CENTER button while the FAN icon is
highlighted to manually re the burner and power
the CH circulator. See Fig. 5
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
dissipate 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 out-
side the recommended combustion settings (see
Table 1), adjust the THROTTLE SCREW (see Fig. 6)
using a at-blade screwdriver as follows:
Counter-clockwise adjustment of the THROTTLE
SCREW at High Fire (100% firing rate):
O2decreases and CO2 increases
Clockwise adjustment of the THROTTLE SCREW at
High Fire (100% firing 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
settings in Table 1 contact Triangle Tube Technical
Support.
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
