Installation and Operation Instructions
Lx – WH Series
34
The initial lighting of the water heater must be performed by a licensed Gas Technician.
Failure to follow instructions may result in property damage, serious injury or death.
Ensure the water heater 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 Trinity Lx and turn-up the Thermostat(s). The water heater 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 water heater 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 water heater.
3.
This water heater 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 water heater.
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 water heater” and contact a professional
service technician, or gas supplier.
Turning Off The Water heater
1.
Set the thermostat to the lowest setting, and then turn off all power to the water heater.
2.
Turn the gas shut-off valve to the off position.
