Installation and Operation Instructions
Tx Series
26
Extra precaution must be taken to adequately support the weight of the Vent/Air-inlet
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 Tx. Failure to follow these instructions will
result in fire, property damage, serious injury or death.
Removing an Existing Boiler from Common Venting System
Do not install the Trinity Tx into a common venting system with any other boiler. 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.
Upon removal of an existing boiler, the following steps shall be followed for each boiler remaining in the
common venting system; prior to commencing this procedure, shutdown all boilers remaining in the common
venting system.
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 applicable 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 to
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.
