Horizontal Through The Wall Venting - Goodman GSM Installation & Operating Instructions Manual

This appliance may be horizontally vented through an exterior wall following the applicable instructions
in the "VENTING" section in conjunction with these additional requirements.
ALL HORIZONTAL VENT INSTALLATIONS MUST BE MADE IN ACCORDANCE WITH THESE
INSTRUCTIONS.
When selecting which exterior wall to penetrate, the following items should be taken into
consideration:
1. Layout the combustion air and vent system to avoid the possibility of interference with beams,
poles, posts, electrical wiring, plumbing, etc.
2. When possible the combustion air and vent termination should not be subjected to prevailing
winds.
3. The combustion air intake and vent termination must be located at least twelve (12) inches above
expected snowfall. Consideration should be made to past unusual snow falls.
• DO NOT locate the terminal less than seven (7) feet above public walkways. This applies to steps
and stairwells.
• DO NOT locate the termination areas where condensate may present a problem such as flower
beds, patios, etc.
• DO NOT locate within four (4) feet of a gas meter, electric meter, or gas regulator.
• DO NOT locate the vent terminal within four (4) feet of an adjacent building.
• DIRECT VENT INSTALLATION - DO NOT locate the vent terminal within twelve (12) inches of an
operable window or door.
• NON-DIRECT VENT INSTALLATION - DO NOT locate the vent terminal less than (12) inches
above a door or operable window.
• NON-DIRECT VENT INSTALLATION - DO NOT locate the vent terminal less than (4) feet below
or (4) feet horizontally from any door, window or gravity air inlet into any building.
• DO NOT locate the vent terminal less than three (3) feet above, or (10) feet horizontally from, a
forced air inlet into any building, other than the combustion air supply pipe.
• DO NOT locate the vent terminal within three (3) feet of an inside corner of a building or structure.
Minor corners created by fireplace chimneys are excluded from this requirement.
To protect the exterior surface from staining due to the condensate, an aluminum plate or similar
material may be installed surrounding the termination. This plate should extend approximately two (2)
feet from the termination.
The area surrounding the vent terminal and combustion air supply pipe must be kept free of snow,
trash, bushes or any other obstacle which may cause a blockage. A blockage can cause
CARBON MONOXIDE to enter the building.
