NTI Ti100-200 Installation And Operation Instructions Manual page 18

Trinity │Installation and Operation Instructions
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. Failure to follow instructions will result in fire, property damage, serious
injury or death.
Removing an Existing Boiler from Common Venting System
Do not install the Trinity Ti into a common venting system with any other boilers. Failure to comply
with this warning will cause flue gas spillage and leech carbon monoxide emissions into the
surrounding air resulting in serious injury or death.
When an existing boiler is removed from a common venting system, the common venting system is
likely to be too large for proper venting of the remaining boilers connected to it. Instructions have been
provided on how to remove the existing boiler and how to resize the remaining venting system. Failure to follow these
instructions may result in property damage, serious injury or death.
At the time of removal of an existing boiler, the following steps shall be followed with each boiler remaining connected to the
common venting system placed in operation, while the other boilers remaining connected to the common venting system are not
in operation.
Steps to Removing an Existing Boiler
1. Seal any unused openings in the common venting system.
2. Visually inspect the venting system for proper size and horizontal pitch. Verify that there is no blockage, restriction, leakage,
corrosion or other deficiencies which could cause an unsafe condition.
3. Insofar as is practical, close fireplace dampers, all building doors and windows and all doors between the space in which the
boilers remaining connected to the common venting system are located and other spaces of the building. Turn on clothes
dryers and any boiler not connected to the common venting system. Turn on any exhaust fans, such as range hoods and
bathroom exhausts, so they will operate at maximum speed. Do not operate a summer exhaust fan.
4. Place in operation the boiler being inspected. Follow the lighting instructions. Adjust thermostat so boiler will operate
continuously.
5. Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or
candle, or smoke from a cigarette, cigar or pipe.
6. After it has been determined that each boiler remaining connected to the common venting system properly vents when tested
as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas burning boiler to their previous
condition of use.
7. Any improper operation of the common venting system should be corrected so the installation conforms with the National
Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CAN/CSA B149.1, Natural Gas and Propane Installation Code. When
resizing any portion of the common venting system, the common venting system should be resized to approach the minimum
size as determined using the appropriate tables in Part 11 of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or
CAN/CSA B149.1, Natural Gas and Propane Installation Code.
