8. Where long periods of airflow are desired for comfort, use
long fan cycles instead of continuous airflow.
9. Apply other good venting practices as stated in the
venting section of the National Fuel Gas Code
ANSI Z223.1 “latest edition”.
10. Vent connectors serving appliance vented by
natural draft or non-positive pressure shall not be
connected into any portion of a mechanized draft
system operating under positive pressure.
11. Horizontal pipe runs must be supported by hangers,
straps or other suitable material in intervals at a
minimum of every 3 feet of pipe.
12. A furnace shall not be connected to a chimney or flue
serving a separate appliance designed to burn solid fuel.
13. The flow area of the largest section of vertical vent or
chimney shall not exceed 7 times the smallest listed
appliance categorized vent area, flue collar area, or draft
hood outlet area unless designed in accordance with
approved engineering methods.

WARNING
!
The cabinet must have an uninterrupted or unbroken
ground according to National Electrical Code, ANSI/
NFPA 70 – “latest edition” and Canadian Electrical Code,
CSA C22.1 or local codes to minimize personal injury if an
electrical fault should occur. A failure to follow this warn-
ing could result in an electrical shock, fire, injury, or death.
▲
CAUTION
!
The integrated furnace control is polarity sensitive. The hot
leg of the 115 VAC power must be connected to the BLACK
field lead.
▲
WARNING
!
To prevent injury or death due to electrical shock or contact
with moving parts, lock unit disconnect switch in the open
position before servicing the unit. Failure to follow this
warning could result in electrical shock, personal injury, or
death.

* THIS REQUIREMENT COVERS MOST INSTALLATIONS
External Masonry Chimney
Venting of fan assisted appliances into external chimneys (one
or more walls exposed to outdoor temperatures), requires the
chimney be lined with type “B”, double wall vent or suitable
flexible chimney liner material. This applies in all combina-
tions of common venting as well as for fan assisted appliances
vented alone.

WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow the installation instructions for the venting
system being placed into operation could result in carbon
monoxide poisoning or death.
The following installation practices are recommended to
minimize corrosion caused by condensation of flue products in
the furnace and flue gas system.
1. Avoid an excessive number of bends.
2. Horizontal runs should pitch upward at least 1/4" per foot.
3. Horizontal runs should be as short as possible.
4. All vent pipe or connectors should be securely supported
and must be inserted into, but not beyond the inside wall
at the chimney vent.
5. When vent connections must pass through walls or parti-
tions of combustible material, a thimble must be used and
installed according to local codes.
6. Vent pipe through the roof should be extended to a height
determined by National Fuel Gas Code or local codes. It
should be capped properly to prevent rain water from
entering the vent. Roof exit should be waterproofed.
7. Use type “B” double wall vent when vent pipe is routed
through cool spaces (below 60° F.).
