OMPLIANCE APPLICABLE CODES & STANDARDS Codes United States: NFPA 54/ANSI Z223.1 - National Fuel Gas Code NFPA/ANSI 211 - Chimneys, Fireplaces, Vents and Solid Fuel Burning Appliances Canada CAN/CSA B149.1 - Installation Codes for Gas Burning Equipment Standards UL 1738 - Venting Systems for Gas-Burning Appliances, Categories II, III, and IV ULC S636-95 - Standard for Type BH Venting Systems Sheet Metal and Air Conditioning Contractors - Thermoplastic Duct Construction Manual National Association (SMACNA)
Therefore, any venting system used with the TRIUMPH Series boiler must comply with the requirements for Category IV venting systems as specified in NFPA 54/ANSI Z223.1, Chapter 12 in the US or with CAN/CSA B-149.1, Chapter 8 in Canada.
Applicable Vent Materials By Boiler Model UL 1738 or ULC S636 CPVC Models Metallic Vent CPVC ULC S636 T750 T1000 CANADA OMBUSTION Combustion air must be free from dust, lint, etc. The presence of such materials in the air supplied to the burner could cause nuisance "Low Air"...
∑ Minimum free area of the opening is 1 square inch for each 3000 Btu/hr (700 mm / kW) of installed appliance input capacity, and ∑ Not less than the sum of the areas of all vent connectors in the room. When using two permanent openings, one opening shall be not more than 12 inches above the floor and the other not more than 12 inches below the ceiling, preferably on opposite walls.
When a duct is used to meet the requirement for combustion air supply, as described above, the opening of the duct shall be located so there is no possibility of cold air affecting steam or water piping, electrical equipment or mechanical equipment. When combustion air is supplied by mechanical means, an airflow-sensing device must be installed.
WARNING Improper use may result in fire or injury. Read instructions/safety manual before installing, operating or servicing boiler. 1998 HCS, Inc. 800-748-0241 Reorder No. 6020-V2WHPK Do not use a barometric damper with this boiler. This is a positive pressure system. Flue gases may leak into the room.
CLEARANCES Provide clearances between combustion air intake, exhaust vent, roof and wall surfaces, doors and window, and snow line. Refer to Fig 3.1 for details. Fig 3.1 Termination Clearances Forced Draft and Direct Vent Installations Conventional Vent Systems ∑ The vent system shall terminate at least 3 ft above a forced air inlet within 10 feet horizontally. ∑...

Interior Installation All vent system components shall be installed so as to maintain the following required minimum clearances to combustibles: ∑ Unlisted single wall metal pipe 18 in. ∑ Single wall CPVC pipe 18 in. ∑ Factory built chimney Per manufacturer s listing NOTE: If the vent is erected directly behind the boiler, make sure that the weight of the vent is not supported by the boiler vent collar.
To prevent the possible re-circulation of flue gases, your vent designer must take into consideration such things as prevailing winds, eddy zones, building configurations, etc. Triad Boiler Systems cannot be responsible for the effects such adverse conditions may have on the operation of the boilers. Dimensions listed above or those illustrated are minimum, and may not be sufficient for conditions at a specific job site.
TRIUMPH Series Boilers are certified as direct vent appliances, with a sealed ducted combustion air inlet and venting system. Air flow-through is maintained by the fan inside the boiler assembly. Allowable locations of vent and air intake terminations are shown in Fig.

∑ After it has been determined that each appliance 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 appliance to their previous conditions of use. Any improper operation of the common venting system should be corrected so the installation conforms with the National Fuel Gas Code, ANSI Z223.1 and CSA B149 Installation Code.
NTAKE XHAUST AYOUT Four basic configurations for the intake/exhaust may be used.. Refer to Section 3.3 for required clearances for all terminations shown in the four following figures. Sidewall Vent and Roof Inlet Roof Vent and Inlet Sidewall Vent and Inlet Roof Vent and Sidewall Inlet...
