Vent Piping Guidelines

G61MPVT furnaces, with the exception of the G61MPVT−60D−135, can be installed as either a Non−Direct Vent or a Direct Vent gas central furnace. The G61MPVT−60D−135 can only be installed as a Direct Vent (two pipe) gas central furnace. NOTE − In Non-Direct Vent installations, combustion air is taken…

Use the following steps to correctly size vent pipe diameter

Refer to Vent Pipe Size Determination Worksheet on page 52. 1 − Determine the vent termination and its corresponding equivalent meter value per table 6. 2 − Determine the number of 90° elbows required for both indoor and outdoor use. Calculate the corresponding equivalent meters of vent pipe. 3 −…

Venting Practices

1 − Use recommended piping materials for exhaust piping (Class E / Class 12 / Schedule 40). 2 − Secure all joints so that they are gas-tight using approved cement. Suspend piping using hangers at a minimum of every 1.52m (5 feet) for Schedule 40 vent pipe. A suitSTRAPPING able hanger can be…
