Matrix Installation a nd Operatio n Instructions

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.

3.1 Vent Pipe Mat erial

IMPORTANT

Field supplied piping and fittings are required to complete the installation. Selection of the vent pipe material must be based upo n the Local codes and regulations. The Matrix is certified to oper ate under all conditions using the following vent ing material:

Exhaust Vent Pip ing:

The first 3 feet of the exhaust venting must be readily accessible for inspect ion. In Canada all exhaust pipe, fittings and cement must comply with ULC S636 (As per ULC S636, only CPVC can be used). In U.S. exhaust pipe and fittings must comply with ANSI/ASTM D1784 and DF441 for PVC and CPVC respectively. Cement and primer must comply with ANSI/ AST M D2564 and F493 for PVC a nd CPVC respectively.

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.

• Maximum inp ut requirement of all gas

appliances in the residence.

Ensure 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.

• 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.

Note: Line pressure adjustments can only be made at the gas regulator, NOT AT THE GAS VALVE.

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.

Matrix Installation a nd Operatio n Instructions

6.1 Plumbing (Min imum Requirements )

Pressure Re gulator “F ill Valve” (Supp lied): The Matrix operates as a boiler to provide heat, thus it must be installed and

operated as such. A 12-15 PSI pressure regulator is provided with the Matrix and must be field installed as per the installation instructions. Note: Local authorities may require the installation of a certified “back-flow preventer” immediately before the pressure regulator.

Circulating Pump (Supplied): The Matrix has a built-in circulator to pump water from the boiler to either the internal forced-

air heating coil or the inter nal domestic coil (brazed plate heat exchanger). An external circulator is only required if the Matrix is

also being used to supply heat to a hydronic heating s ystem, the external circulator must be sized for the requirements of the hydronic heating system.

Rel ief Va lve (Supp lied ): A 30PSI Relief Valve is provided with the system, it is to be mounted with the discharge in the

horizontal. Ensure that the dischar ge is piped to a location were steam or water won’t cause personal injury or appliance and property damage.

Air Purging ( Supplied): Boilers are designed to operate with airless water in the system. The Matrix design allows for the

evacuation of air from the internal plumbing. For installations in conjunction with a hydronic heating system an Air Scoop, installed as shown in the following diagrams, must be installed to remove air as it circulates through the system. If air continues to be a problem an air scrubber must be used (recommend Spirovent # VJR 100TM).

Expansion T ank (Supplied): The Matrix comes with a built-in expansion tank that is sized to handle the volume of water in the

Matrix unit. An external expansion tank must be field sized, supplied and installed for Matrix units installed in systems with hydronic heat.

Low Water Cutoff:

A certified LWCO is not provided in the package, however one is to be field installed in any application where the Matrix boiler is located above the radiation or where local authorities require it. Ensure that the water line of the “Low Water Cutoff” is at least 6” above the top of the boiler. It is recommended that the LWCO be situated so that it can be tested without removing water from the Matrix. Tri-cocks and a gauge glass are highly recommended. NTI recommends against the installation of isolation valves between the LWCO and the Matrix. Use the normally open contacts of the LWCO to break 24V to the burner circuit (See Wiring Diagram).

CAUTION

DAMAGE WILL OCCUR IF THE BOILER IS FIRED WITH NO WATER IN IT, OR REPETITIVE NO FLOW O PERATIONS, WHICH WILL VOID THE WARRA NTY.

6.3 Hydronic Heat ing Additions (Opt ional)

ATTENTION

1. LOW TEMPERAT URE A PPL I CATIONS (i.e. , In-f loor) r equire the use of mixing contr ols suc h as a Tekmar injection syst em or t hermostatic m ixing v alves (See 6. 2.3 to 6. 2.4) . During a cal l for “Forced- Air He at” the Mat rix will o perate at a constant ly var ying boiler water te mperatur e, this te mperature may at ti mes exceed the maximum allowable temperature for some or all of the hydronic zones.

2. HI TEMPERATURE APPLICATIONS (i.e., finned tube baseboard) do not require mixing controls, however, when t he Matrix is operating dur ing a call for Forced- Air Heat the hydron ic system will o nly receive the heat left over f r om the M atrix air handler; keep t his in mind dur ing system sizing and design.

3. In applications that do not use zone valves it is important to incorporate int o the system design means necessary to prevent T HERMA L SIPHONING. Note: the following drawin gs are to be used as a reference

only for the system designer .

Matrix Installation a nd Operatio n Instructions

The M atrix provides heat t o hydronic heat i ng syst ems in t wo ways:

Hydronic C all (24 VAC @ H without a call for forced air heating) – A boiler demand is initialized by sending a ‘Hydronic

Demand’ . The boiler will then maintain a set point of ‘HYD’ (See Table 9.3).

Hydronic S hared Call (24 VAC @ H concurrent with a forced air call) – With this demand the forced air system is given

priority. The set point temperature will be the higher of the ‘HYD’ setting or the forced air set point. During a shared call the hydronic system can only receive the water temperature returning from the fan coil.

If, during a shared call, the boiler can not supply e nough heat to maintain a mi nimum plenum air temperature of 95°F, the Fan Controller will shut-off the hydronic loop using the N.O/N.C contacts on the terminal board until the forced air temperature recovers.

The Matrix has a Grundfos 15-42 built into the primary loop. Given the head loss of the primary loop, the flow rate is fixed at 5 gpm. When designing any secondary heating system it is important to allow for an increase boiler set point to ensure full capacity of the secondary system. This may necessitate the use of mixing valve to protect the secondary from elevated water temperatures.

Example. For a 75,000 Btu/hr secondary system with a desired water temperature of 110°F and 20° ∆T the flow rate will

required is BTU/ hr/(500* ∆T) or 75,000/(500*20) = 7.5 gpm. Since this exceeds the flow rate in the primary loop, a higher boiler ∆T will be required to maintain the desired 110°F. This is calculated as follows:

∆Tboiler = ∆Tsecondary* gpm

= 20*7.5/5

secondary

/gpm

primary

= 30°F

Adding the ∆Tboiler to the return water temperature of 90°F (110°F-20°F) gives a required ‘HYD’ set point of 120°F.

7.0 Do mest ic Hot W at er S ystem

7.1 Oper at ion and Set- up

The Ma trix he a ts domestic hot water o n demand , indi rec tly, using a brazed plate hea t exchanger. Whe n do mes tic wate r passes through the flow switch at a flow rate greater then 0.5 GPM, the switch closes completing a 24VAC circuit between R and FS on the Matrix terminal strip. The Matrix immediately goes into domestic mode, regardless of what other systems may have been operating, the burner fires and the Matrix attempts to achieve the programmed H20 setting, which represents the boiler water temperature set point for domestic mode operation. Because the Matrix uses boiler water to indirectly heat the domestic water, via the brazed plate heat exchanger, the H20 domestic setti ng must be higher then the required domestic hot water temperature (See Section 9.2.1). To achieve a controlled domestic hot water supply temperature, NTI provides a Thermostatic Mixing Valve adjustable from 100 to 145°F. Note, code requirements may require the maximum setting to fixed at 120°F, see “Thermostatic Mixi ng Valve” below and the instructions included with the valve.

For improved domestic hot water comfort, the Matrix incorporates a “Storage” feature. This storage feature, when enabled, will keep the boiler water hot for a period of 1 to 24 hours following a call for domestic hot water. When the boiler water drops below 140°F the boiler will fire and bring the boiler to 180°F before shutting off. This “Storage” feature helps in reducing the wait time associated with a tankless hot water system. In systems where a storage tank is used, this feature should be disabled.

Thermostatic Mixing Valve: A Sparcomix AM101-US-1 is provided with your package. This valve regulates the water

temperature leaving the plate heat exc hanger, and must be used in every instance. The dial can be set to the desired temperature

required. Consult the Honeywell manual SD/IS150 for detailed instructions and settings. (Note: the valve must be set to a s upply

temperature of not more then 120˚F. It is the responsibility of the installer to set the valve and remove the dial.)

WARNING

IF THE ANTI-SCALD VALVE IS NOT INSTALLED TO THE HONEYWELL SHEET ‘SD/IS150’, AND THIS MANUAL, OPERAT IO N MAY SUP PL Y SCAL DING HOT WATER TO T HE OCCUPANT S.

Flow Switch ( Supplied): The Ma trix comes with a domestic flow switch that must be field installed in the location shown. It is

important the flow switch be installed in the cold water line before the cold-water branch to the Mixing Valve or in the mixed out line, thus the flow switch will have the total domestic hot water flow rate available to trigger it and initiate the hot water call. Dirt and other debris can cause the flow switch to fail. Therefore it is important to install the switch in the vertical up position, as recommended by the manufacturer. It is also recomme nded to install a filter (100 micron) on the incoming water if tests show particles larger than 100 microns.

Check Valve: A chec k valve must be field provided and installed on the outlet of the mi xing valve to prevent expansion devises

down stream from back flowing when the water pressure drops during cold water draws. Failure to prevent the backflow will cause water to flow forward through the flow switch, activating it, when the cold-water draw has ended and the water pressure increases.

Throt tling Valve: Installed a throttling valve, after the mi xing valve, to regulate the maximum hot water flow rate. The Matrix is

limited to a firing rate of 150MBH; therefore excessive flow rates will result in cooler hot water temperatures.

Drain Valves: Install drain valves on the inlet and outlet of the brazed plate heat exchanger so it can be flushed free of possible

build-up caused by dirt or hard water.

Hard Water: To prevent the formation of scale on the inside of the brazed plate heat exchanger and other components i n the

domestic hot water system, water with hardness higher than 50 ppm Calcium Carbonate must be treated with a “Water Softener” prior to entering the appliance. Plugging of the domestic system by scaling or accumulation of dirt is not the responsibility of NY Thermal Inc., and suitable steps shall be taken to avoid it.

Cleaning: Brazed plate heat exchangers operate with high turbulence flow, even at low flow rates. This high turbulence keeps

small particles in suspension minimizing fouling and scaling. However, in some applications the fouling tendency can be very high, e.g. when using extremely hard water at high temperatures. In such cases it is always possible to clean the exchanger by circulating a cleaning liquid. Use a tank with weak acid, 5% phosphoric acid or, if the exchanger is frequently cleaned, 5% oxalic

Matrix Installation a nd Operatio n Instructions

acid. Pump the cleaning liquid through the exchanger. For optimum cleaning, the cleaning solution flow rate should be a minimum of 1.5 times the normal flow rate, preferably in a back-flush mode. After use, do not forget to rinse the heat exchanger carefully with clean water. A solution of 1-2% sodium hydroxide (NaOH) or sodium bicarbonate (NaHCO3) before the last rinse ensures that all acid is neutralized. Clean at regular intervals.

DHW Limitations: As the Matrix produces domestic hot water instantaneously; there are inherent li mitations of the system:

NO STORAGE - As there is no water storage, the boiler can only provide water at the temperature specified at the corresponding

flow rates. Flow through the fixtures must be regulated so flows don’t exceed the ability of the boiler to heat the water. MORE FLOW = LESS TEMPERATURE.

DOESN’T MAINTAIN TEMPERATURE – When there is no call for domestic the unit is off. From a dead stop the unit will detect flow and start providing heat in 15 seconds, and be up to capacity by 25 seconds. Once running, the unit can provide an endless amount of hot water. If the flow is momentarily turned off for whatever reason, the unit will turn off. Once off, the unit must relight, and not provide heat for 45-75 seconds. This will cause cold unheated water to pass through the unit, and advance through

the domestic plumbing between the previously heated (hot) water, and the new (hot) water. This can be mistaken for an inability to adequately heat the water.

Procedure for Set t ing up Domestic Hot Wat e r: If the Matrix is being installed in an application that uses municipal water,

often the pressure is high enough to generate flow rates at the faucets that will exceed the appliances capacity to heat it. See the following table to determine what flow can be expected at various inlet and outlet water temperatures.

Inlet Water Temperature (deg. F)

To avoid having too much flow at your faucets use the throttling valve after the mixing valve to limit the overall flow of domestic hot water. If the flow rates listed in the table are not high enough for the application, install a storage tank with re-circulating loop as per Section 7.2. Follow these instructions to achieve the best delivery of DHW. Open throttle valve fully.

Turn the dial on the mixing valve to the desired setting (do not exceed 120˚F or a dial setting greater then 2).

Create the maximum amount of DHW flow that is likely to occur on a regular basis. (Usually tub faucet, or choose two other faucets) Allow the boiler to reach steady state, and then throttle the shut-off valve until the hot water exiting the plate heat exchanger is warmer than the mixed water exiting the mixing valve. Ensure the boiler is firing at the maximum rate, if not increase the LO setting and repeat this step. (It is beneficial to keep the LO setting as low as possible to limit short cycling and maintain efficiency)

The Matrix used two devices to control the functions required by the Matrix. The Matrix Boiler Control (red face) controls and ensures the safe operation of the boiler functions of the Matrix much the same as the Sentry 2100 does in the Trinity products. The Matrix Fan Control (blue face) controls all of the operation and safety func tions related to air handling and hot water dispatching. The fan controller controls the forced air modulation, ventilation, as well as priority of domestic hot water and secondary heating systems.

ATTENTION

9.2 Oper at ion and Set- up

The Matrix employs a pneumatic modulation system. This modulation system increases or decreases the velocity of the combustion 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. The Sentry reads the boiler water temperature, compares it to the set point, and adjusts the burner firing rate accordingly by varying the speed of the combustion blower.

The boiler control reacts to two main inputs: A-C and T-C. The following table shows the response by the boiler control to the

different states of each input. For more information on ‘RESET MODE’ see section ‘9.3 Outdoor Sensor Operation’.

9.3 Out door Sensor O per at ion

The outdoor sensor is connected to the termi nal board on the left side of the matri x. The two terminals are labeled ‘OUTDOOR SENSOR’.

Fig ur e 9.1 Outdoor Sensor Connection

When the Outdoor sensor is not used, or the outdoor temperature is below 0°F, the Matrix operates at a boiler water temperature equal to the HYD or HI setpoint during a call for Hydronic or Emergency Heat respectively. When the sensor is used and the outdoor temperature is above 0°F, the Matrix boiler control automa tically reduces the operating temperature of the boiler during those calls. Using the following formula, the control factors in the current outdoor temperature, control setpoint (HYD or HI), and the RES (reset) setpoint, in determi ning the appropriate operating water temperature.

Figur e 9.2 Outdoor Reset Calculation

Formula: Operating Temperature = {(RES – Outdoor Temp) x (HYD – RES) / RES} + RES

Note: Substitute HYD fo r HI du ring a call for Emergency He a t.

Example:

• There is a call for Hydronic heat; therefore the control uses the HYD programmed

setting.

• The HYD is programmed to be 160°F.

• The RES is programmed to be 85°F.

• The outdoor temperature is 40°F.

Operating Temperature = {(85 – 40) x (160 – 85) / 85} + 85 = The following c h a rt illu s tr a te s th e e ffe c t o f c hanging outdoor tem perature on the boiler operating

what is shown

A`tual Output rates may vary from

Example. At stage 4 (Profile 1) the Matrix provides 675 cfm across the fan coil, which is receiving 128°F water from the boiler. The

coil then supplies plenum air at 113° F or ~30,000 BTU/hr. (1.08x675x(113-72)=30,000)

On an initial thermostat call (24VAC @ W1), space heating begins by providing heat at stage 3 (~24,000 BTU/hr) (if hydronic heat is also calling (24VAC @ H) heating will begin at stage 1) and so long as the thermos tat is not satisfied, incrementally increases to a maximum of stage 10 (~66,000 BTU/hr). When the thermos tat becomes satisfied, an average of the heat output rate during the call is calculated. The boiler remains lit and the space heat output begins an incremental decrease in heat output rate beginning with the stage just below the calculated average and ending with either the thermostat re-calling or if the thermostat never re-calls, the outp ut rate decreases to mini mum stage after whic h the boiler shuts off.

If the thermostat re-calls prior to the minimum heat stage, a new calculated average of the thermostat off cycle is calculated and the boiler again begins an increasing ramp, only this time it begi ns at the calculated stage and not necessarily at the minimum stage.

This computation “hunts” for the heat loss of the dwelling based on the reaction of the thermostat to the rise and fall of the space temperature and the heat cycle rate of the thermostat.

If at any time the plenum temperature exceeds 160°F, the boiler will stop supplying heat until the temperature in the supply plenum drops below 140ºF, during which ti me an AL2 error message will be displayed.

ATTENTION

The burner wi ll r ema in on and t he M at r ix wil l provide heat when the thermostat is of f . This is norma l and i s required to pr ovide constant ef f ici ent heat .

Call for Heat (24VAC @ W1): Normal Thermostat call, Matrix operates as a step-modulating furnace as described above. If

HRV set to ‘ON’, HRV will operate at the low (continuous) ventilation rate.

Matrix Installation a nd Operatio n Instructions

Call for Auxiliary Heat (24 V AC @ W2) : When calling, furnace will provide heat at a stage 10 output rate. With a call for

auxiliary heating the Matrix will function as a single stage, full fire appliance. This means the burner will come on with a thermostat call and go off when the call is satisfied. If HRV set to ‘ON’, HRV will operate at the low (continuous) ventilation r ate.

Outdoor Sensor: The auxiliary heating function

10.2 Duct Sizing

When sizing ductwork, a maximum flow velocity of 800 fpm is desired. Table 11 shows common duct sizes at specified flows. The maximum flows that can be expected are shown in Table 10.3. It is important to maintain the return plenum pressure as low as possible. Keeping this ductwork as free flowing as possible will offer more supply static pressure to overcome A/C coils, closed registers etc while mai ntaining cons tant flow.

Any additional filtration, humidification, or de-humidification equipment should be installed external to the return or supply ducts so

not to create additional restriction.

11.1 Ventilation Needs

With the evolution toward more energy efficient, tighter homes, air quality problems have increased. With less natural ventilation pollutants such as pet dander, humidity, tobacco smoke and wood ash now become trapped inside the home. Mechanical ventilation is the process of exhausting the polluted air from the space and replacing it with fresh air from outside. The amount of ventilation required varies from home to home and can be estimated using one of the following methods:

11.4 Condensate Drai n

Condensation from defrost will collect in the ventilator and drain from the sloped drain pan. This condensation must be evacuated from the unit. The condensate tubing provided must be routed through the hole in the side of the appliance and attached to the 90° elbow directly underneath the ventilation module. From there the condensate tube must be emptied into a suitable floor drain or if necessary the emptying drain must have a trap to prevent the infiltration of toxic gases.

11.5 HRV Balancing

The HRV must be balance properly in order to operate at maximum efficiency and avoid problems.

The balancing process ensures the volume of fresh air from outside is equal to the amount of stale air being expelled from the ho me over all air handler conditions. A variation of 10% is acceptable with the greater volume being stale air drawn from the home.

The Matrix uses motor speed to balance airflows. This method of balancing provides quieter operation and reduced energy consumption over the traditional balancing damper approach.

Flow is measured with the use of a Magnehelic (0-.25 inwg range) and an airflow grid, flow collar or “Flow Measuring Station”. NTI offers an airflow grid, PN: 83554, that is designed to be installed in a 1” hole located in a 6” duct. It is important that the flow grid be the same size as the ductwork, and be installed according to the manufacturers instruc tions. Typically a straight run of 18” on either side of the flow grid is adequate to avoid false readings. It is helpful if a flow grid is installed in each of the supply and exha ust duc ts.

Procedure.

Attach the upflow port of the flow grid to the positive pressure port of the Magnehelic and the down flow port to the negative port. Zero the Magnehelic. Begin by selecting the heating profile required in the Matrix Fan Controller ‘HEA’ menu. Refer to the heating section of the manual for more explanation. The heati ng profile selected dictates the air handler blower speeds and is important to the proper functioning of the HRV. Every time the heating profile is changed the HRV will require re-balancing. Once the heating profile is selected, advance to the ‘BAL’ menu. By pressing the ‘FUNCTION’ button you will enter the balancing mode of the HRV. Press the up arrow button and advance through the menus until you reach the ‘EOH’ menu item. By pressing the ‘FUNCTION’ button you will enter the ‘EOH’ menu. A number will appear. You will notice the HRV start, if it is not already running, and the main blower of the air handle will come up to speed. The number on the display represents the speed of the HRV fan in percentage. In the case of ‘EOH’ the number shown represents the speed of the exhaust ‘E’ fan during a call for hi gh ventilation ‘O’ (override) while the air handler blower is running at the high ‘H’ heating speed. The maximum speed setting is 100%, the minimum 30%. Adjust the speed up or down until the desired flow rate is achieved. Table 11.1, on the following page, has been provided to help in explaining the different settings. Complete the table adjusting each of the setting to the HRV Ventilation Rate provided. These rates are a guideline only and can be adjusted to meet the specific application.

-Note- When adjusting the exhaust speeds, the supply fan will increase to full speed.

When the balancing is complete, the HRV will maintain balance at any ventilation rate during any air handler blower condition. This is a unique feature of the Matrix and is essential in providing efficient and adequate ventilation in this integrated system.

ATTENTION

The HRV balance must be checked and if necessary rebalanced every time the Heating (HEA) setting is changed, or if there is chan ge to the system which wo uld sig nificantly change the static pressure at th e return plenum or the ext er ior duct s t o t he HRV.

12.0 LIGHTING BOILER

12.1 Init ial Start-Up

Ensure that the boiler is wired in accordance with this manual. Ensure that the gas shut-off valve is turned on, and that the gas system has been fully tested for leaks. Ensure that the system is completely filled with water, and that ALL of the air has been purged from the system.

Turn on power to the Appliance. The unit should run through a purge, and combustion should occur. (The control system has a built

in ignition retry, allowing the system to retry at least four times, before locking-out.) Verify that the gas line pressure is 4-9”wc. for natural gas, and 9-12” wc. for propane.

Using an appropriate Oxygen or Carbon Dioxide analyzer, take a sample of the flue gas. The sample must fall within the acceptable

ranges for carbon Dioxide, which is 8% - 9.5% for natural gas, and 9.0%-10.5% for propane. If the reading does not fall within

this range, contact NY Thermal, for assistance.

Perform at least three lights in succession to ensure proper operation.

After the three successive lights, unplug the flame probe, and allow the unit to cycle again. Ensure that it tries to light, and locks out on safety reset. Once you have successfully activated the flame safety system, replace the wire on the flame sensor, and reconfirm

proper lighting.

13.0 T ROUBLE SHOOTING

This section is intended to assist the service technician in detecting and correcting common errors. The Matrix Boiler and Fan Controls are equipped with an internal diagnostic system that verifies control operation. The following series of error codes has been developed to aid in diagnosing control problems:

Symptom Detected Problem Solution

1. If the boiler is extr emely hot check for adequat e water pressure and circula tion, contact NTI for assistance.

2. If not hot, check for sources of groundin g or shorting at the Water Sens or electr ical connections, check wiring from Sen sor to Boiler (Red) Control.

3. Replace Water Sensor if the resistance is not in the correct range. (See th ermister resist ance charts in Figur es 13.1 and 13.2)

See ER1

1. Check wiring to Water Sensor for open circuits or shorting to ground. (Note: ER3 will be displ ayed if temperatur e sen sed is less then 0°F.)

2. Replace Water Sensor if the resistance is not in the correct range. (See th ermister resist ance charts in Figur es 13.1 and 13.2)

1. Res et power, if error goes away the problem is intermitt ent and was likely caused by a tripped limit th at has automatically reset , check f or adequate water pressur e and fl ow rate. Allow the boiler to cycle and verify proper operation inclu ding outlet water temperatur e and flue temperatur e. If operation is unsucces sful and the err or reoccurs:

2. Mat r ix boiler s are equipped with a low water pressure switch on the boiler return that requ ires a minimum of 10PSI to complete the 24VAC ignition circuit . Ensure the field-in stalled pres sur e gauge is reading a minimum of 12PSI. Replace water pressure switch if plumbing and pres sure is correct and if it measur es an open circuit.

3. Chec k f or continuity through the 24VAC limit wiring and manifol d and stack limits, replace limits or wiring that are not a closed circuit.

1. Res et the ER5 error by resetting the power or cycling the DHW call. Check for pr oper operat ion of the DHW call.

2. Matrix units are provided with a DHW flow switch; ensure it is not sticking in th e closed position wh en there is no DHW flow. If so, remov e it and free it of any debr is and check for proper oper ation, replace if necess ary (water shoul d be filtered prior to flow switch.

There is a problem in the ignition sequ ence; it could be caused by a faulty igniter, flam e sens or, gas valve or improper line pressur e or combustion.

3. Ch eck for proper polarity of line and neutral wiring to the boiler.

1. Ensure the plumbing is as shown in manual. Check to see if pum ps are operatin g pr operly and water pressur e is above 15psi. This problem can

lead to boiler overheating!

2. Boiler m ay be pluggin g with scale or magnetite, cl ean with Fernox DS-40 Descaler and Cleanser (NTI PN: 83450).

3. If glycol is being used th e concentration may be to high, recommend using a concent r ation lower then 35%.

1. Ensure that the venting lengths are in compliance with Section 3.4

2. Ensure that the line p ressure during operatio n does not drop more than 20% from the static line pressure.

3. Momentarily remove the intake vent from the boiler durin g ignition, if unit lights smoothly with intake vent disconnec t ed reconnect and ch eck for proper combu st ion if unit maintain s smooth operat ion after ignition. ( See Section

5.2) Calibrate for proper combustion . If problem persists contact NY Thermal.

4. Heat exchanger may be dirty, remove burner door and inspect, clean if necessary.

1. Use flexible gas line to insolate the vibration noises between the gas valve and the li ne.

2. Don’t hang gas lines from floor joists.

3. Use rubber insulators with gas line support s.

1. If gas valve is not held when the gas nipple is connected, the force of tight ening the fitting can damage the valve, and warp the fan housing.

2. If pipe is u sed, the gas line must not create any forces to the valve, either vertical ly (weigh t of line), or horizont ally (m isal igned connect ion)

The following are the thermistor curves for diagnosing the water and outdoor air sensors:

1. Measure the resistance of the thermistor when disconnected.

2. Using the appropriate chart, find the resistance and move either vertical (water probe) or horizontal (air probe) until the line is intersected.

3. Move 90 degrees to the corresponding temperature.

4. If the temperature is plus or minus 10 degrees, then the probe is operating correctly.

15.0 I NS TALLATION CHECKLIST

Installation

Connect all plumbing, and ensure that there are no system leaks. Connect, secure, and glue all vent piping. Install all gas piping as per this manual, and local codes. Pressure test, to detect any gas leaks.

Start-up

Install pressure gauge (Gauge= 0” to 15” w.c. scale) and check line and manifold pressures. (See “Section 5.2”) Turn gas shut-off valve to the ON position. Turn Power on to boiler. Set Sentry Controller to desired settings. Turn thermostat up, Ignition will occur.

Operat ional Checklist

Ensure that Carbon Dioxide Readings are within the acceptable ranges. Using an appropriate Oxygen or Carbon Dioxide analyzer, take a sample of the fl ue gas. The sample must fall withi n the acceptable Carbon Dioxide ranges, which is 8% - 9.5% for natural,

and 9.0%-10.5% for propane. (See Table 5.1)

Before Leaving

Remove gauge from gas valve and tighten bleed screw and test plug for leaks. Allow boiler to complete at least one complete cycle, or at least 15 minutes running time.

Always verify proper operation after servicing

Matrix Installation a nd Operatio n Instructions

16.0 ANNUAL MAINTE NANCE AND INSPECTION

This unit requires very little maintenance, however a Qualified Technician should inspect it at the beginning of every heating season.

Inspection Check list:

Lighting is smooth and consistent, and the combustion fa n is noise & vibration free. The condensate freely flows from the unit, and is cleaned of sediment. Relief Valve and air vents are not weeping. Low water cut off is flushed (if applicable) Examine all venting, for evidence of leaks, and vent screens are cleaned. Check the burner plate for signs of leaking. Verify the vent clearance as per Section 3.0 Listen for water flow noises indicating a drop in boiler water flow rate. The boiler and hydronic system may need to be flushed to eliminate hard water scale (Use Fernox DS-40 Descaler – NTI PN: 83450).

IMPORTANT

It is imperative that you expla in t o t he homeowner t hat it is t heir responsibi l ity t o:

• Keep the vent terminal free of snow and i ce.

• Periodically check the vent terminal for debris.

16.1 Combustion Cha mb er Cleaning Once every second year the burner (No.1 – See 17.0 Parts List) and the burner door (No.19) should be removed so the

combustion burner and chamber can be inspected for flue gas blockage. Suc h blockage will reduce the boiler’s capacity/firing rate and can impact negatively on how smooth, efficiently and reliably the boiler operates. Remove debris from inside the burner using compressed air or vacuum; if water is used ensure the burner is completely air dried upon completion. Carefully remove the insulation (No.32) from the back of the combustion chamber and vacuum out any loose build-up. With water and a non-metallic scrub brush, thoroughly clean the heat exchanger surfaces, including in-between the tubes (note: the flue gases must pass inbetween the tubes). Rinse with a garden hose allowing the dirty water to wash out through the condensate drain, repeat until water runs clean. Once complete, clean the condensate trap and drain lines.

16.2 HRV/ Air Handler Maintenance

WARNING

ALWAYS REMOVE POWER (120V) TO THE UNIT PRIOR TO SERVICING.

Once every three months. Replace furnace filter. May be required more frequently in begi nning, especially if new

constr uction.
