Clearances
2.0 INSTALLATION REQUIREMENTS
The installation of your NY Thermal Trinity gas boiler must conform to the requirements of your local
authority, and the National Fuel Gas Code ANSI Z223.1 and or CAN/CGA B149 Installation Codes.
Where required by the Authority, the installation must conform to the standard for “Controls and Safety
Devices for Automatically Fired Boilers ANSI/ASME CSD-1.
Important: Carbon Monoxide Detectors
A carbon monoxide detector must also be installed in the room that houses the boiler. Carbon
monoxide detectors shall comply with NFPA 720 (2005 Edition).
“In the state of Massachusetts only”
If there is not one already present, on each floor level where there are bedroom(s), a carbon monoxide detector
and alarm shall be placed in the living area outside the bedroom(s).
If the bottom of the vent and air intake terminal is installed below four feet above grade, the carbon monoxide
detector located in the boiler room shall:
a. Be powered by the same electrical circuit as the boiler such that only one service switch services both the
appliance and the carbon monoxide detector;
b. Have battery back-up power;
c. Meet ANSI/UL 2034 Standards and comply with NFPA 720 (2005 Edition); and
d. Have been approved and listed by a Nationally Recognized Testing Laboratory as recognized under 527
CMR.
ATTENTION: LIQUEFIED PETROLEUM (LP) PROPANE
The Trinity boiler is set to operate with Natural Gas, an LP Conversion Kit Part No. 82066-1 for Ti150 and 82650-1 for
Ti200 is included with each boiler and must be installed before operating with Propane.
Liquefied Petroleum (LP) propane gas is heavier than air; it is imperative that your boiler is not installed in a pit or
similar location that will permit heavier than air gas to collect. Local Codes may require appliances fueled with LP gas
be provided with an approved means, of removing unburned gases from the room. Check your local codes for this
requirement.
2.10 LOCATION
In all cases, the Trinity boiler must be installed indoors, in a dry location, such that the gas components
are protected from dripping or spraying water or rain, during operation and servicing. The boiler location
ambient temperature is maintained to a minimum of 50°F.
Determine the best location of the vent termination, and if possible locate the boiler as close to the
termination point as possible.
For proper and safe installation adhere to the following clearances to combustibles:
Boiler Casing=0" Floor=Combustible Flue Pipe: Boxed in or enclosed=2” In free air=0”
The following are the minimum clearances for servicing, however 24” is recommended:
Front = 24” Back = 0" Top = 12" Sides = 12" Bottom = 12"
Ensure that the desired boiler location is not subjected to flooding or high moisture levels, for damage to
the boiler will occur, voiding your NY THERMAL warranty.

3.0 VENTING
The NY Thermal Trinity condensing gas boiler
is a high efficiency boiler utilizing induced
power venting, which is designed to be vented
directly outdoors, using the venting method
detailed in this section. Under no conditions,
may this unit vent gases into a masonry
chimney, unless it is vacant, and utilizes the
Trinity approved venting material (Solid core ABS or PVC
steel pipe) as illustrated in the figures on page 5.
3.1 VENT PIPE MATERIAL
Selection of the vent pipe material must be based upon the Local codes and regulations. The
Trinity boiler is certified to operate under all conditions using solid core ABS or PVC
CPVC. Local codes may prohibit the use of plastics, and stainless steel venting must be used
(AL29-4C).
3.2 VENTING CLEARANCES
1. It is highly recommended that the vent terminal be located where it will not be exposed to normal
prevailing winds.
2. The exhaust must be a minimum of 18” above the air inlet, and the air inlet must always be a
minimum of 12” plus snow allowance above any surface that will support snow. (Two feet plus snow
allowance is highly recommended). Consult your weather office, for the maximum typical snowfall for
your region. Example: New Brunswick Canada the maximum typical snowfall is 19”, Thus in figures of Section 3.3, the
inlet must be (12”+19”) = 31” off the ground, the exhaust must be (31”+18”) = 49”.
3. The horizontal distance between the inlet and exhaust must be a minimum of 4” center to center. If
the horizontal distance between the inlet and exhaust is more then 12”, increase the vertical
separation by the same amount. Example: If horizontal separation is 24”, a minimum vertical
separation of 30” is required (24”-12”=12”), so increase minimum vertical separation by 12”),
(18”+12”=30”). If horizontal distance is greater then 6’, no additional vertical spacing is required.
Vertical separation is never required to be greater then 36”.
4. Under normal operating conditions this appliance will produce a plume of white gases, and should be
taken into consideration when selecting an adequate location. A 3’ diameter stainless, plastic, or
vinyl shield can be used to flash the exterior of the residence.
The vent terminal shall not terminate:
• Directly above a paved sidewalk or a paved
driveway that is located between two
buildings, and that serves both buildings;
• Less than 7 feet above grade where located
adjacent to a paved driveway or public walkway.
• Within 3' (three feet) horizontally of a window or door that can be opened, or non-mechanical air
supply inlet to any building.
• Within 6’ of a mechanical air supply inlet to any building, or roof eve containing soffit openings.
• Above a meter/regulator assembly within 3' horizontally of the vertical centerline of the regulator.
• Within 6' of any gas service regulator vent outlet.
• Less than 30” plus snow allowance above grade, or any surface that will support snow, ice, or debris.
The exhaust must be a minimum of 18” above the air inlet, and the air inlet must always be a
minimum of 12” plus snow allowance above any surface that will support snow. (Two feet
plus snow allowance is highly recommended). Consult your weather office, for the maximum
typical snowfall for your region.

Notes
1.) If the horizontal distance between the inlet and exhaust is more then 12”, increase minimum
vertical separation by the same amount. (If horizontal distance is greater then 6’, no additional
vertical spacing is required). Example, horizontal separation equal to 24” requires a minimum
vertical separation of 18”+(24”-12”) =30”. (Vertical separation is never required to be greater
then 36”)
2.) Elbows on outside of wall must be no greater than ½” away from the wall.
3.) All indoor exhaust piping must be on a slope back to the boiler ¼” per linear foot of vent. (See
figure after #11. Recommended way to have plumb pipe connection to boiler.)
4.) Exhaust and Inlet venting must have screens installed at the termination (See figure page 7).
5.) Exhaust vent pipe can be secured to the wall for more rigidity.
6.) In all roof applications the discharge must point away
from the pitch of the roof.
7.) Install adequate flashing where the pipe enters the
roof, to prevent water leakage.
8.) Install and seal a rain cap over existing chimney
openings, in vacant chimney applications.
9.) For installations that exit the wall below grade.
Excavate site as shown in figure, to a point below
where the pipes are to exit. Ensure that the wall is
fully sealed where the pipes penetrate the wall. The
vent piping MUST be secured to the side of the
building above grade, as shown, to provide rigidity.
NTI Provides a mounting bracket PN. 82075 for
securing the exhaust pipes. Ensure that the vent clearances are maintained (Inlet minimum 12”
plus snow allowance from grade, exhaust outlet 18” minimum above inlet)

10.) Install the vent screens provided into both the inlet and exhaust vent terminal elbows.
The screen must be on the outside of the last elbow. Install the screen into the female opening of
the elbow. Then cut a small piece of pipe to sandwich the screen into the elbow. NOTE be sure
that the small piece of pipe cut, does not extend past the end of the elbow. Two screens are
provided in the package.
11.) It is extremely important that the intake and exhaust piping be
adapted to 3” immediately at the boiler using the appropriate adaptors.
Use a 3” to 2” adaptor on the exhaust and a 3” to 1½” adaptor at the inlet.
12.) All interior vent pipe shall be supported every 24”
It is recommended that two
elbows be used, so that the
slope of the horizontal
exhaust vent (1/4” per foot)
does not affect the vertical
plumb of the pipe connected

3.4 DETERMINING VENT LENGTHS
Use the following chart to determine the
maximum amount of vent pipe that can be
used. This chart calculates, sweep and 45º
elbows, and 90º elbows at 5 equivalent feet.
Combustion air that contains chloride,
fluoride, bromine, or iodine can cause
corrosion of the heat exchanger,
voiding your warranty.
Warning
IMPORTANT:
• The length of one vent pipe (intake or exhaust) may not exceed the length of the other vent
pipe by more then 20 equivalent feet.
• The three 90° elbows of the exterior vent piping (two outlet, and one inlet) do not have to
be included, as they are taken into consideration in the vent calculations.
• 2” venting cannot be used.
• For Propane Gas (LP) maximum vent length cannot exceed 50 equivalent feet.

product of combustion. Much of this
water condenses on the heat
exchanger and in the venting
system. All exhaust piping must be

on a slope back to the boiler ¼” per
linear foot of vent. Steps must be taken to ensure that condensate does not collect in the venting
system. Condensate must be drained from the boiler into a household drain.
Note: check with your municipality, or local gas company to determine if disposal of combustion
condensate is permitted. In the State of Massachusetts the condensate must be neutralized
prior to entering a drain.
The following are important notes that must be taken into
consideration when constructing the condensate system:
• DO NOT run condensate line outside. A frozen or blocked
drain will cause the condensate to fill the combustion
chamber. This will result in a no heat condition, as the unit
will shut down, and damage to the flame sensor, and
components can occur.
• NEVER use copper, steel, or galvanized piping in the
construction of the condensate system.
• When a condensate pump is used or required, select a
pump that is designed for residential furnaces.

Insure that:
• Flexible gas pipe is used (if acceptable by local codes). The gas valve and blower cannot support
the weight of piping, leading to blower vibration and damaged components. If rigid piping is used,
ensure that the valve supports NO WEIGHT
• You plan the installation so that the piping does not interfere with the vent pipe, or the removal of
the valve, burner, and serviceable components.
• The Boiler shall be installed such that the gas ignition system components are protected from
water (dripping, spraying, rain etc.) during installation and servicing.
• The gas piping is large enough for all the appliances in the home. No appreciable drop in line or
manifold pressure should occur when any unit (or combination of units) lights or runs.
• Always use a pipe-threading compound that is resistant to propane (LP) gas solvent action. Use
sparingly to all male threads, starting at two threads from the end. Over doping or applying dope
to the female end, can result in a blocked gas line.
• DO NOT TIGHTEN FITTINGS WITHOUT SUPPORTING THE GAS VALVE as damage to the
valve or motor can occur.
• Install a manual “equipment Shut-Off Valve” as shown. Valve must be listed by a nationally
recognized testing lab.
5.2 Testing and settings

Caution
The Trinity is tested with Natural Gas having a
heating value of 1020 BTU per cubic foot. For
areas with lower heating values, a combustion
test is required to obtain optimum operation.
The Trinity boiler employs a pneumatic
modulation system. This modulation system
increases or decreases the velocity of the
blower, to meet the demand for heating. The
gas valve senses this change in blower
pressure and introduces the required amount
of gas to ensure correct combustion.

Warning
This boiler must have adequate water flowing through it
whenever the burner is on. Failure to do this will damage
the unit and void the warranty.
Warning for all Systems
All systems must be flushed to remove sediment, flux,
filings, etc. Failure to do so will seriously damage the
boiler, voiding warranty. (Recommend using Fernox
cleaning products “Superfloc” for new installations and
CHR “Central Heating Restorer” for retrofits)
Warning for all Systems
The boiler fittings can’t support any weight. Support all
of the plumbing system externally.
Do not apply torque to the boiler fittings. Hold the fitting
when installing, otherwise damage to the unit will occur.
Caution: This boiler is designed to operate in residential and commercial heating systems, and is
not intended for:
1. Outdoor installations, or unheated spaces, which can cause freezing.
2. Process heating of potable water, or any other fluids.
3. Un-pressurized, and gravity feed heating systems.
4. Heating systems with very low pressures or flow.
