  • Page 18 Trinity │Installation and Operation Instructions Ti Series Extra precaution must be taken to adequately support the weight of the Vent/Air-Intake piping in applications using roof-top terminations. Failure to follow these instructions may result in venting or boiler component failure resulting in flue gas spillage leading to property damage, serious injury or death. Under no circumstances may an existing chimney or chase-way be used to vent or provide combustion intake air to a Trinity Ti.

  • Page 19: Condensate Drain

    Installation and Operation Instructions │Trinity Ti Series 5.0 CONDENSATE 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.

  • Page 20: Installing Gas Piping

    Ensure that:  The gas line connection to the appliance does not apply any weight to the gas valve. NTI recommends using approved flexible gas piping (if acceptable by local codes) to connect the appliance to the gas supply (See Figure 6-1 for details).

  • Page 21: Lighting The Appliance

    Installation and Operation Instructions │Trinity Ti Series 7.0 LIGHTING THE APPLIANCE Before Start-up refer to Mandatory Pre-commissioning Procedure for Plastic Venting in Section 3.0. Failure to follow these instructions can result in explosions, injury or death. Prior to turning the gas supply on and lighting the appliance, ensure all aspects of the installation are complete and in conformance with the instructions provided in this manual, including the Vent/Air- Intake, Condensate Drain, and System Water Piping.
  • Page 22 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 assistance at 1-800-688-2575. Never allow the appliance to continue to operate if the ignition or operation of the burner is rough or erratic.

  • Page 23: Gas Valve And Burner Set-Up

    Installation and Operation Instructions │Trinity Ti Series 8.0 GAS VALVE AND BURNER SET-UP Set-up of the Trinity Ti gas valve must be performed by a licensed Gas Technician. Failure to perform the set-up correctly may result in incorrect operation, component failure, property damage, serious injury or death.
