Plan Vent System
IMPORTANT: The venting system must be supported with
mounting straps to keep any weight load from being applied to
the vent blower. Horizontal vent pipe must be supported every
5 ft (1.5 m) and vertical pipe should be supported every 10 ft
(3 m) to avoid sagging and provide rigid support.
Materials
■ All pipe, fittings, primer, and solvent cement must conform
with American National Standard Institute and the American
Society for Testing and Materials (ANSI/ASTM) standards.
The solvent shall be free flowing and contain no lumps,
undissolved particles, or any foreign matter that adversely
affects the joint strength or chemical resistance of the
cement. The cement shall show no gelatinization,
stratification, or separation that cannot be removed by
stirring. See Piping and Fitting Specifications chart for
approved piping and fitting materials.
2" or 3" (5.1 cm or 7.6 cm) nominal diameter PVC Schedule
40 pipe meeting ASTM D1785, PVC primer meeting ASTM F656
and PVC solvent cement meeting ASTM D2564 specifications
must be used. Fittings must be DWV type fittings meeting ASTM
D2665 and ASTM D3311. Carefully follow the manufacturer’s
instructions for cutting, cleaning and solvent cementing of PVC.
Schedule 40 PVC Cellular Core (Foam Core) Plastic Pipe is a
coextruded poly (vinyl chloride) (PVC) plastic pipe with a cellular
core (contains numerous cells intentionally introduced,
interconnecting or not, distributed throughout the pipe) and
concentric inner and outer solid layers. PVC primer meeting
ASTM F656 and PVC solvent cement meeting ASTM D2564
specifications must be used. Fittings must be DWV type fittings
meeting ASTM D2665 and ASTM D3311. Carefully follow the
manufacturer’s instructions for cutting, cleaning and solvent
cementing of PVC.
To ensure proper furnace operation, this Schedule 40 PVC
Cellular Core (Foam Core) Plastic Pipe must be installed in
accordance with the installation instructions, all local building
codes and ordinances. In their absence, follow the latest edition
of the National Fuel Gas Code (NFPA 54/ANSI Z223.1), and or
CAN/CGA B149 Installation Codes, local plumbing or wastewater
codes, and other appliance codes.
Goodman 53
Failure to follow these instructions can result in bodily
injury or death. Carefully read and follow all instructions
given in this section.
WARNING
Goodman 54
Upon completion of the furnace installation, carefully
inspect the entire flue system both inside and outside of
the furnace to assure it is properly sealed. Leaks in the
flue system can result in serious personal injury or death
due to exposure to flue products, including carbon
monoxide.
WARNING
Goodman 55
To avoid bodily injury, fire or explosion, solvent cements
must be kept away from all ignition sources (for example,
sparks, open flames and excessive heat) as they are
combustible liquids. Avoid breathing cement vapors or
contact with skin and/or eyes.
