Field W iring Connection V enting General Appliance Categories Heaters are divided into four categories based on the pressure produced in the exhaust and the likelihood of condensate production in the vent. Category I – A heater which operates with a non-pos- itive vent static pressure and with a vent gas t emperature that avoids excessive conden[...]

T able L: V enting Category Requirements V ent T er minal Location 1. Condensate can freeze on the vent cap. Frozen condensate on the vent cap can result in a blocked flue condition. 2. Give special attention to the location of the vent termination to avoid possibility of property dam- age or personal injury . 3. Gases may form a white vapor plume [...]

5. T erminate vent at least 6 ft away from adjacent walls. 6 . DO NOT terminate vent closer than 5 ft below roof overhang. 7. The vent terminal requires a 12 in. vent terminal c learance from the wall. 8. T erminate vent at least 1 ft above grade, including normal snow line. 9. Multiple direct vent installations require a 4 ft clearance between the[...]

T able M: Category IV V enting 1 V ent lengths are based on a lateral length of 2 ft. Refer to the latest edition of the NFGC for further details. 2 Consult factory for longer vent runs. * Subtract 10 ft per elbow . Max. 4 elbows. ** Adapters supplied by others. T er mination The vent terminal should be vertical and should termi- nate outside the b[...]

Common V enting The NFGC does not address sizing guidelines for the common venting of multiple Category IV heaters. This is covered in the NFGC under “Engineered V ent Sys- tems”. T able N provides the volume of flue products at full fire for the calculation of appropriate vent sizing and extractor for common venting. WARNING: V ent connectors [...]

The figures in this manual show the drain in a vent tee, however , this can also be accomplished using an in[...]

The vent must be installed to prevent flue gas leakage. Care must be taken during assembly to ensure that all j oints are sealed properly and are airtight. The vent must be installed to prevent the potential accumulation of condensate in the vent pipes. It is required that: 1 . The vent must be installed with a condensate drain located in proximity[...]

C ombustion air supplied from outdoors must be free of particulate and chemical contaminants. T o avoid a blocked flue condition, keep the vent cap clear of snow , ice, leaves, debris, etc. The stainless steel flue direct vent cap must be fur- nished by the heater manufacturer in accordance with its listing (sales order option D-15). Outdoor Instal[...]
