Installation and Operation Instructions Matrix
24
The initial lighting of the boiler must be performed by a licensed Gas Technician.
Failure to follow instructions may result in property damage, serious injury or death.

Ensure the boiler is wired in accordance with this manual.

Ensure the gas shut-off valve is turned on, and that the gas system has been fully tested for leaks.

Ensure the system is completely filled with water, and that ALL the air is purged out.
Allow primers/cements to cure for 8 hours prior to Start-up. If curing time is less than 8
hours,
first perform Steps 2 through 6 of Mandatory Pre-commissioning Procedure for
Plastic Venting in Section 4.0. Failure to follow these instructions can result in explosion,
serious injury or death.
Initial Start-Up
1. Turn on power to the Matrix and turn-up the Thermostat(s). The boiler should run through a purge, and
combustion should occur. (The control system has a built in ignition retry, allowing the system to try at least
three times, before locking-out.)
2. With the unit operating at full capacity, verify that the gas line pressure is 5.5-10.5 inches w.c. for Natural
gas, and 9-13 inches w.c. for Propane (See Section 9.0 for details).
3. 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 8.8% - 9.8% for Natural gas, and 9.8%-10.8%
for propane (See Section 9.0 for details).
4. Perform at least three lights in succession to ensure proper operation.
5. 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.
If the unit fails to light consistently and smoothly, contact NTI for technical assistance at
1-800-688-2575. Never allow the boiler to operate if the ignition or operation of the
burner is rough or erratic. Failure to follow these instructions may result in serious injury
or death.
The flame probe uses a single electrode located in the burner door at the 6 O’clock
position. DO NOT remove the wire from the dual electrode located in the burner door at
the 3 O’clock position; this device is used for spark igniting and delivers a high voltage
potential which would result in an EXTREME ELECTRICAL SHOCK possibly causing
serious injury or death.
Re-lighting Unit
1. Stop and read these instructions very carefully.
2. Set the thermostat to the lowest setting, and then turn off all power to the boiler.
3. This boiler does not have a pilot. It is equipped with an ignition device that automatically lights the burner.
Do not try to light the burner by hand.
4. Turn the gas shut-off valve to the off position, and then remove the front cover.
5. Wait five (5) minutes to clear out any gas. Then check for gas, including near the floor. If you smell gas
“Stop” and follow “B” above. If you don’t detect any gas proceed to the next step.
6. Turn the gas shut-off valve to the on position, wait an addition five (5) minutes and check for gas.
7. Replace the front cover.
8. Set the thermostat to the highest setting, and then turn on all power to the boiler.
9. Ignition sequence is automatic, combustion will occur after a brief fan purge. Ignition will retry 3 times.
10.
If ignition does not occur, “Turn off the gas and electricity to the boiler” and contact a professional service
technician, or gas supplier.
Turning Off The Boiler
1. Set the thermostat to the lowest setting, and then turn off all power to the boiler.
2. Turn the gas shut-off valve to the off position.
