SUBMITTAL • LTU 13 June-16 12) VENTING - A. BASIC FLUE VENTING -Venting must comply with the latest edition of the National Fuel Gas Code (ANSI Z223.1-latest edition) or the authority having jurisdiction. Other venting references are in the equipment volume of the ASHRAE Handbook. SINGLE HEATER VENTING (VERTICAL THROUGH THE ROOF) 1. When venting the heater to outside of building through a roof, use single-wall metal pipe. This is to be constructed of galvanized sheet metal or other approved noncombustible corrosion-resistant material as allowed by state or local codes. 2. A vent passing through a combustible roof shall extend through an approved clearance roof thimble. Double-wall, Type B vent must be used for the portion of the vent system which passes through the combustible roof.An approved vent cap(Leslie "VersaCap"-Type B or equal) must be attached to end of the flue. 3. The maximum equivalent length of vent pipe should be carefully observed. A safety switch in the heater is designed to shut the heater off before excessive flue restriction causes bad combustion. Refer to the Vent Sizing Table for vent pipe diameter. • Minimum Equivalent Length=5 ft. of pipe • Maximum Equivalent Length =100 ft. of 4" pipe for 40-175 Models and 6" pipe for 180-200 Models Use the following correction factors to obtain the equivalent length: • Subtract 15 ft. if the run is horizontal. (maximum horizontal length for 4" pipe is 25 ft.) • Subtract 10 ft.for an approved vent cap. • Subtract 10 ft.for each elbow beyond 15 ft.from the heater. • Subtract 15 ft.for each elbow within 15 ft. of the heater. 4. Joints between sections of piping shall be fastened by sheet metal screws or other approved means and should be sealed to prevent leakage of flue gas into building. Aluminum or Teflon tape suitable for 550°F (3M Company tapes 433 or 363)or silicone sealant is recommended. 5. Avoid locating elbows in the first 5' of vent pipe whenever possible. Limit to(2)90° elbows.When vent pipe is in a horizontal run, it must have 1/4 inch per foot rise. 6. All portions of the vent pipe shall be supported to prevent from sagging(6'spacing is recommended). 7. When the vent pipe passes through areas where the ambient temperature is likely to induce condensation of the flue gases,the vent pipe should be insulated and a condensation drain should be provided. 8. Minimum clearance for single-wall flue pipe to combustible material shall be 6 inches. This may be reduced when the combustible material is protected as specified in the National Fuel Gas Code or the authority having jurisdiction. 9. Single-wall metal pipe shall not originate in any unoccupied attic or concealed space and shall not pass through any attic, inside wall or concealed space, or through any floor. For the installation of a single-wall metal pipe through an exterior combustible wall, refer to latest edition of the National Fuel Gas Code or the authority having jurisdiction. 10. A venting system shall terminate at least 3 ft.above any forced air inlet located within 10 ft. 4"Vent Pipe (vertical position) Vent Cap .i k 2 ft(77cm)minimum (when no wall or parapet exists) � E #10 Self-Drill _-_ •-10 ft(305cm)–+ 2 minimumft(77cm) Screws Flashingor less (typical) 4 -. „. 1 ABM Starting Collar** 2"(5cm) , Clearance ° Thimble m m � � a y Seal Joint � and Annular * Draft Inducer Space �� 4" Diameter (vertical position) V *6"for LTS/U 180-250 Models **4"x6"Adaptor included for LTS/U 180-250 Models Note: Junction Box is not shown. SUBMITTAL • LTU 14 June-16 SINGLE HEATER VENTING (HORIZONTAL THROUGH SIDEWALL) When venting the heater horizontally through a combustible outside sidewall, the same requirements listed previously for venting Vertical Through The Roof apply except as follows: 1. A vent passing through a combustible wall must pass through an approved clearance thimble(Air-Jet#4VT or Ameri-Vent #4EWT or other thimbles) that are listed by a nationally recognized testing agency. Double- wall Type B vent must be used for the portion of the vent system which passes through the combustible sidewall. 2. An approved vent cap(Breidert-Type L or equal)must be attached to the end of the vent pipe. • 4"vent - 25 ft. maximum with one 90°elbow and vent cap for 40-175 Models • 6"vent - 75 ft. maximum with maximum two 90°elbows and vent cap for all Models If other horizontal vent configurations are required,consult the manufacturer. NOTE:To minimize problems associated with condensation in long horizontal runs,vent pipe can be insulated. 3. When venting through a sidewall,the horizontal vent pipe shall rise not less than 1/4 inch per foot from the start of the vent system to the vent terminal. All portions of the vent pipe shall be supported to prevent sagging.(6'spacing is recommended) 4. A minimum clearance of 6 inches must be maintained between the outside wall and vent cap. 5. The horizontal venting system shall not terminate: • Less than 4 ft. (1.2m) below, 4 ft. (1.2m) horizontally from or 1 ft. (30cm) above any door, operable window or gravity air inlet into any building.The bottom of the vent terminal shall be located at least 7 ft. (2.1m)above grade or above snow accumulation level as determined by local codes. • Less than 3 ft.(0.9m)from a combustion air inlet. • Less than 3 ft.(0.9m)from any other building opening or any gas service regulator. • Less than 7 ft.(2.1m)above public walkways. • Directly over areas where condensate or vapor could create a nuisance or hazard or be harmful to the operation of gas utility meters, regulators, relief valves, or other equipment. Building materials should be protected from flue gases and condensate. • Less than 12"(0.30m)when directly below a combustible overhang. 6. In regions of the country where prevailing winds are consistently higher than 40 mph, it may be necessary to terminate the vent system above the roof level. 4"Vent Pipe* #10 Self-Drill ._6"(15cm), (horizontal position) Screws minimum (typical) Starting Collar** 2"(5cm) Clearance 1 � Thimble Draft Inducer No less than 1/4"(6mm) (horizontal position) rise per foot(0.3m)toward Sidewall Vent Cap vent terminal (Part No.30297040:4" Part No.30297060:6") *6"for LTS/U 180-200 Models **4"x6"Adaptor included for LTS/U 180-200 Models Note:Junction Box is not shown. SUBMITTAL• LTU 15 June-16 MULTIPLE HEATER VENTING (CONNECTIONS INTO A COMMON VENT OR MANIFOLD) Requirements for venting of multiple heaters are the same as described for SINGLE HEATER VENTING except as follows: 1. The common vent size and total vent height is normally determined by the number of heaters per common vent, length of horizontal connector runs, and connector rise. Connector lengths should be as short as possible and have a minimum 1/4 inch per foot rise. Without regard to connector rise and total vent height due to many possible venting configurations,the following should be observed: • Common vent pipe&vent connector diameter should be no less than that shown in the following Vent Sizing Table. • A Y-connector must be used to the common vent. 2. Material for connectors and Y-connectors should be constructed of galvanized sheet metal or other approved noncombustible corrosion resistant material as allowed by state or local codes.All common vent pipe should be insulated flue pipe or double-wall,Type B vent. 3. Avoid unnecessary bends. Limit to two(2)90°elbows. 4. The entire length of vent connector shall be readily accessible for inspection,cleaning and replacement. 5. Groups of heaters with a common vent must be controlled by a common thermostat.

SUBMITTAL • LTU 17 June 16 13) AIR FOR COMBUSTION If indoor combustion air is to be supplied for a tightly enclosed area,one square inch of free area opening shall be provided below the heater for each 1,000 Btu/hr of heater input. Adequate clearances around the perforated fresh air plate must be maintained at all times. In larger open areas of buildings, infiltration normally is adequate to provide air for combustion. 14) DIRECT OUTSIDE AIR FOR COMBUSTION Outside combustion air should be supplied directly to the heater when the building is subject to negative pressure, or when contaminants or high humidity are present in the building air. These contaminants include paints, solvents, corrosive vapors or any other foreign particles that may cause damage to the heater or result in poor combustion. Outside combustion air can be brought directly to the heater by a 6" diameter duct less than 50 ft. long or equivalent. This is attached to the 6" diameter starting collar. The starting collar is fitted to the top of the control box cabinet after first removing and discarding the perforated cover. An approved vent cap must be placed directly on the end of the outside combustion air inlet pipe.The combustion air inlet should be not less than 3 ft. (0.9m), either vertically or horizontally, from the flue vent termination. The air intake terminal must be located not less than 1 ft. (30cm)above grade. It is good installation practice to supply combustion air from the same pressure zone as the vent outlet. Avoid bringing combustion air to the heater from an attic space. There is no guarantee that adequate combustion air will be supplied. If the heater is installed less than 2 ft. from the ceiling, a flexible transition section (e.g., flexible aluminum duct)must be provided to allow for expansion/contraction of straight tube heaters(LTS Series). In colder climates, where necessary, insulate the outside combustion air duct. Avoid locating the outside combustion air duct directly above the control box. Provide a capped cleanout T as necessary. In high humidity applications,the control box should be sealed with silicone sealer. In multiple heater applications,the combustion air intake may be ducted individually or common ducted in the same configuration as shown for venting in Section 13. For combustion air intake duct sizing, please refer to the Vent Sizing Table and use the diameter indicated, based on the number of heaters per duct. >I The combustion air inlet should be not less than 3 ft.
