Power Venter Sequence of Operation
Before installation, it is helpful to understand the fundamental operation and sequencing of the power venter as follows:
1. Venter’s relay coil is wired in series with thermostat—when thermostat calls for heat, thermostat contacts close
circuit.
2. After delay of 15–60 seconds, venter starts.
3. When venter starts, air from venter blower closes pressure switch that is built into venter.
4. Closing of pressure switch completes electric circuit to burner controls to open gas valve.
5. When thermostat is satisfied, gas valve closes.
6. Thermal switch permits post-purge venter blower operation to prevent unnecessary lockouts by temperature-
sensitive blocked vent system on furnace.
7. When venter blower stops, pressure switch opens.

VENTING
⚠ DANGER ⚠
If this furnace is replacing an existing furnace, ensure that the vent is properly sized for the furnace
being installed. A properly-sized vent system is required for safe operation of this furnace. An
improperly-sized vent system can cause unsafe conditions and/or create condensation.
⚠ WARNING ⚠
Units installed in multiples require individual vent pipe runs and vent caps. Manifolding of vent
runs is not permitted.
NOTES:
• Venting must be in accordance with the National Fuel Gas Code Z223.1 or CAN/CGA B149.1 and
B149.2, Installation Code for Gas Burning Appliances and Equipment, and all local codes. Local
requirements supersede national requirements.
• A horizontal vent run is recommended for maximum fuel savings.
With the power venter installed, these furnaces are designed to operate safely and efficiently with either a horizontal
or vertical vent. Use either vent pipe approved for a Category III heater or appropriately-sealed single-wall pipe. Or,
if at least half of the equivalent length of the vent system is vertical, vent pipe approved for a Category I heater may
be used. A vent cap of a type approved for use with this heater is required.
Specific Venting Requirements
Venting requirements change with the addition of the power venter. Comply with the following specific requirements
and instructions:
• Vent pipe: If installed with a horizontal vent run, use either vent pipe approved for a Category III heater or
appropriately-sealed 26-gauge galvanized steel or equivalent single-wall pipe. If at least half of the equivalent
length of the vent system is vertical, vent pipe approved for a Category I heater may be used. Single-wall pipe or
double-wall (Type B) vent pipe are suitable for use with a Category I heater.
• Vent length: Minimum vent length is 5 feet.
• Pipe diameter: Use only one of the diameter(s) listed in Table 7 for the furnace being installed.

*Reduce the vent pipe length by 7 feet (2 meters) for a 45-degree elbow, 15 feet (4.5 meters) for a 90-degree elbow, or 10 feet (3 meters) for
a vent cap.
**If the venter outlet is 4 inches (102 mm), connect a taper-type enlarger to the venter outlet when installing 6-inch (152-mm) vent pipe.
• Vent system joints: Vent system joints depend on the installation and the type of pipe being used. If installed as
a Category III heater (required if more than half of the equivalent length of the vent system is horizontal), use vent
pipe specifically approved for Category III vent systems. Follow the pipe manufacturer’s instructions for proper
sealing. If installed with a Category I vent system (allowed only if at least half of the equivalent length of the vent
system is vertical), use at least two non-corrosive screws per vent pipe joint on single-wall pipe or follow the pipe
manufacturer’s instructions for joining double-wall pipe.
• Vent system support: Lateral runs should be supported every 6 feet using a non-combustible material, such as
strap steel or chain. Do not rely on the heater to support either horizontal or vertical vent pipe.
• Condensation: Any length of single-wall vent pipe exposed to cold air or run through an unheated area or an
area with an ambient temperature of ≤45°F must be insulated along its entire length with a minimum of 1/2-inch
foil-faced fiberglass, 1-1/2# density insulation.
• Vent terminal (pipe and vent cap): The vent cap must be the same size as the vent pipe (vent pipe is either 4
or 6 inches diameter). For optimum stability under wind conditions, use a manfacturer approved vent cap. See
Figure 7 and Figure 8 for requirements of vertical and horizontal vent termination. The vent terminal pipe may be
either single-wall or double-wall (type B). Check local codes for double-wall terminal requirement. If double-wall
pipe is used in the vent terminal with a single-wall vent run, follow the instructions below to attach the vent cap
and to connect the double-wall pipe to the single-wall vent pipe run.
⚠ WARNING ⚠
Vent terminal arrangements illustrated are applicable only to units with a power venter. Horizontal
vent termination requires a power venter. DO NOT use horizontal vent with gravity venting.

Single-Wall Vent/Double-Wall Terminal
Single-Wall Vent/Single-Wall Terminal
Figure 8. Horizontal Vent Terminal
⚠ DANGER ⚠
If the vent terminal is to be installed near ground level, position it at least 6 inches above maximum
anticipated snow depth.
NOTE: Products of combustion can cause discoloration of some building finishes and deterioration
of masonry materials. Applying a clear silicone sealant that is normally used to protect concrete
driveways can protect masonry materials. If discoloration is an esthetic problem, relocate the vent
or install a vertical vent.
• Horizontal vent terminal clearances: A vent cap is required. Maintain a clearance of 18 inches from the wall to the
vent terminal cap for stability under wind conditions. The location of the termination of the horizontal vent system
must be in accordance with National Fuel Gas Code Z223.1. Required minimum clearances are listed in Table 8.

VENTING—CONTINUED
Connecting Vent Cap To Double-Wall (Type B) Vent Terminal Pipe
1. Position vent cap at exhaust end of double wall pipe—refer to flow arrow on vent pipe.
2. Slide vent cap inside pipe.
3. Drill hole—slightly smaller than screw being used—through overlap of vent cap and pipe.
4. Secure vent cap to pipe using 3/4-inch-long sheet metal screw.
5. Drill two more holes evenly spaced (120-degrees apart) and install two additional screws.
Connecting Single-Wall Vent Run to Double-Wall (Type B) Vent Terminal Pipe
1. Slide single-wall pipe inside inner wall of double-wall terminal pipe.
2. Drill hole—slightly smaller than screw being used—through both walls of double- and single-wall pipe.
3. Secure two pieces of pipe using 3/4-inch-long sheet metal screw. Do not overtighten.
4. Drill two more holes evenly spaced (120-degrees apart) and install two additional screws.
5. Seal annular opening (gap between single- and double wall pipe) with large bead of silicone sealant in opening.
Bead of sealant must be large enough to seal opening, but it is not necessary to fill full volume of annular area.
OPERATIONAL TESTING
⚠ DANGER ⚠
• DO NOT put a heater into service that does not properly exhaust flue gases to the outside
atmosphere.
• The gas burner in this gas-fired equipment is designed and equipped to provide safe and
economically-controlled complete combustion. However, if the installation does not permit the
burner to receive the proper supply of combustion air, complete combustion may not occur.
The result is incomplete combustion, which produces carbon monoxide, a poisonous gas that
can cause death. Safe operation of indirect-fired gas burning equipment requires a properly-
operating vent system which vents all flue products to the outside atmosphere. FAILURE TO
PROVIDE PROPERVENTINGWILL RESULT IN A HEALTH HAZARDTHAT COULD CAUSE SERIOUS
PERSONAL INJURY OR DEATH.
• Always comply with the combustion air requirements in the installation codes and instructions.
Combustion air at the burner should be regulated only by manufacturer-provided equipment.
NEVER RESTRICT OR OTHERWISE ALTERTHE SUPPLY OF COMBUSTION AIR TO ANY HEATER.
Indoor units installed in a confined space must be supplied with air for combustion as required by
code and in the heater installation manual. MAINTAIN THE VENT SYSTEM IN A STRUCTURALLY-
SOUND AND PROPERLY-OPERATING CONDITION.
1. Turn on the electric and the gas.
2. Refer to lighting instructions provided with furnace to light unit.
3. Test unit for proper venting:
a. With building at maximum negative pressure, operate furnace at normal input.
b. Note and check flow direction at relief opening of drafthood—room air should be flowing into relief opening.
