3.0 VE NTING
The NY Thermal Matrix is a high efficiency condensing gas furnace/boiler utilizing induced power venting. Exhaust gases are to
be vented directly outdoors, using the venting me thod detailed in this section. Under no conditions, may this unit vent gases into a
masonry chimney, unless it is vacant, and utilizes Matrix approved venting material as illustrated in the figures in this section.
Attaching Vent P ipi ng t o Boi ler
It is extremely important for the inta ke and exhaust piping to be adapted to the appropriate size immediately upon exiting the boiler
cabinet. The Matrix comes with a 3” male PVC fitting to connect the air intake port of the boiler.
The Matrix exhaust connection is 3” male PVC, use approved cement to connect to venting system.
Check t he fl ue outlet gasket for prop er i nser ti on and sea ling prior to and after attachi ng the ve nting.
Ensure the venting system does not apply a load or stain on the flue outlet of the boiler (recommend using two elbows to create a
“swing joint” as shown above).
Fig ur e 3.1 Venting Const r uction
It is recommended that two elbows be
used, so that the slope of the hori zontal
exhaust vent does not affect the vertical
lumb of the pipe connected to the boiler.
Slope all horizontal indoor exhaust
vent ing ¼” to ½” per linear foot.
It is recommended to have a collection point
for condensation in the intake venting.
Condensation can then be drained to an
open house dr ain or condens ate pump.
Drain line from intake must have an
appropriate trap or shut off valve to avoid
siphoning.
IMPORTANT
The vent connection and piping must be perfectly aligned to the furnace connection. AND MUST NOT
APPLY ANY W EIGHT OR LATERAL FORC E TO T HE FLU E BOX. NTI do es not warrant y damages to t he flu e
box.

USE OF EXI STING CHIMNEY
It is permissible to run vent pipe t hrough an exist i ng chimney as long as:
1. The chim ney is not to be used by any other appliance.
2. Flue gases don’t enter the vacant chim ney.
3. O nly Trinit y c er t ified venti ng materials are used, see Sect ion 3.1.
4. Vent lengths are within the maximums specified.
3.3 Venting Rules and G uide lines
1. It is highly recommended that the vent termi nal be located where it will not be exposed to normal prevailing winds.
2. The exhaust mus t 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 highl y recommended). Consult your weather
office, for the maximum typical snowfall for your region. Example: New Brunswick Canada the typical maximum snowfall is 19”,
Thus in figures of Section 3.3, the inlet must be (12”+19”) = 31” off the ground, the exhaust mus t be (31”+18”) = 49”.
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 exha ust 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 mini mum 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”.
3. Under normal operating conditions this appliance will produce a plume of white gases, and sho uld 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.
4. 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” require s a mi nimum ve rtical separation of 18”+(24”-12”) =30”. (Vertical separat ion is neve r re quired t o be
greater then 36”)
5. Elbows on outside of wall must be no greater than ½” away from the wall.
All indoor exhaust piping mus t be on a slope back to the boiler a minimum of ¼” per linear foot of vent. For applications where
excessive condensation is possible ½” per linear foot is recommended. (See figure after #11. Recommended way to have plumb
pipe connection to boiler.)
6. Exhaust vent pipe can be secured to the wall for more rigidity.
7. In all roof applications the discharge must point away from the pitch of the
roof.
8. Install adequate flashing where the pipe enters the roof, to prevent water
leakage.
9. Install and seal a rain cap over existing chimney openings, in vacant
chimney applications.
10. 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 tha t 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 mi nimum 12” plus snow
allowance from grade, exhaust outlet 18” mi nimum above inlet)
11. 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 s mall 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.
12. It is extremely important that the intake and exhaust piping be adapted to the appropriate size immediately upon exiting the
boiler cabinet.
13. All interior vent pipe shall be supported a minimum of every 36”.

Matrix Installation a nd Operatio n Instructions
3.4 Venting Clearances
These are code restrictions for the location of the Flue gas vent ter minal. Compliance doesn’t insure a satisfactor y installation; good
common sense must also be applied.
The vent terminal shall not t er minate:
1. Directly above a paved sidewalk or a paved driveway that is located between two buildings, and that serves both buildings;
2. Less than 7 feet above grade where located adjacent to a paved walkway or driveway located on public property.
3. Within 3' (three feet) of a window or door that can be opened, or non-mechanical air supply inlet to any building.
4. Within 6’ of a mechanical air supply inlet to any building, or roof eve containing soffit openings.
5. Above a meter/regulator assembly withi n 3' horizontally of the vertical centerline of the regulator.
6. Within 3' horizontally of any gas service regulator vent outlet up to a height of 15’.
7. 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 mi nimum 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 yo ur regi o n.
8. Underneath a wooden verandah, porch, or deck.
9. Underneath cement verandah, porch, or deck, unless both ends are open and the exhaust pipe is installed at least 24” under the
deck floor.
10. So situated that the flue gases are directed towards brickwork, siding, or other construction, in such a manner that may caus e
damage fro m heat or co ndensate from the fl ue gas es.
11. Less than 3’ from an inside corner of an L-shaped structure (including walls and fences).
12. Install the warning plate “Gas Vent Di re c t ly B e lo w” 4 feet above the location of the air inlet pipe, so it is visible from at least
eight (8) feet away (Plastic Label included in the Installation Manual Package – see figure).
3.5 Deter mining Vent Lengt hs
Use the following chart to determi ne the maximum amount of vent pipe that can be used. This chart calculates, sweep and 45º
elbows, and 90º elbows at 5 equivalent feet. Note: chart shows allowable equivalent vent lengths for intake and exhaust vents
separately, thus an M100V operating on Natural Gas can be installed with 105 equivalent feet of intake venting and 105 equivalent
feet o f exhaus t venti ng.
IMPORTANT
The length of one vent p ipe (intake or exha ust) ma y not exceed t he lengt h of the other vent pipe by mor e
then 20 equivalent f eet .
The thr ee 90° elbows of t he exterior vent piping (two outlet, and one inlet) do not have to be included, as
they are taken into considerat ion in t he vent calculations.
Propane Gas (LP) maximu m vent length cannot exceed 50 equivalent f eet .

4.0 CON DE NS ATE DRAIN
This unit produces water as a 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.
WARNING
FAILURE TO PROPERLY CONNECT THE CONDENSATE LINE WILL CAUSE COMBUSTION GASES TO
ENTE R THE ROOM, POSSIBLY C AUSING SERIOUS INJ URY T O OCCUPANTS O R DEATH.
Note: c hec k with your munici pality, or l ocal ga s co mpa ny to determine i f
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 NO T 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 (condensate is very corrosive and will wrought most me tals).
When a condensate pump is used or required, select a pump that is designed for
residential furnaces.

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.
• Al ways use a pipe- thr eading compo und t ha t i s resistant to pr opa ne (LP) gas s olvent actio n. Us e spar ingl y 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 “equipme nt Shut-Off Valve” as shown. Valve must be listed by a nationally recognized testing lab.
5.2 T esting and sett ings
Gas line and regulator(s) must be able to support a line pressure at the gas valve of 4-9”w.c for Natural Gas and 9-12”w.c for LP
while running at maximum rate. Matrix gas valves are equipped with two bleed ports to measure Line and Manifold pressure.

CAUTION
The M atrix is tested w ith Natural Gas having a heat ing value of 1020 BTU p er cubic foot . For areas with
lower heating valu es, a combusti on t est is required to obtain optimum operation.
Using a calibrated flue gas anal yzer, check the combustion and compare it with the acceptable requirements. The test should be
performed at maximum fan speed (“Gas Input Value”).
Adjusting Combustio n - Use the input screw to adjust the amount of gas available for combustion. Increasing gas increases CO
and CO2. Reducing gas decreases CO and CO2.
CO – At maximum fan speed, the CO reading is
the most critical to the safe operation of the boiler.
The CO should be no higher than 175 PPM at any
condition. If the CO is over 140 PPM, the input
should be reduced until the CO is less than 140
PPM or the CO2 is reduced to 8% (9% for LP Gas).
If the CO is over 140 PPM and the CO2 is less than
8% (9% for LP Gas), contact NTI for assistance.
CO – At minimum fan speed, should be checked, and the CO should be less than the reading recorded at high fan speed. The CO
at low fan speed must not be at least as high as the CO2 recorded at high fan speed, but not more then 9.5% (10.5% for LP Gas).

*Note: On colder days CO2 should be closer to the lower number, on warmer
days it should be closer to the higher number. CO should be highest at the
maximum firing rate.
