WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each appliance connected
to the venting system being placed into operation could result in carbon
monoxide poisoning or death.
The following steps shall be followed for each appliance connected to
the venting system being placed into operation, while all other
appliances connected to the venting system are not in operation:
1.Seal any unused openings in venting system.
2.Inspect the venting system for proper size and horizontal pitch, as
required in the current edition of National Fuel Gas Code, ANSI
Z223.1/NFPA 54 and these instructions. Determine that there is no
blockage or restriction, leakage, corrosion and other deficiencies,
which could cause an unsafe condition.
3.As far as practical, close all building doors and windows and all doors
between the space in which the appliance(s) connected to the venting
system are located and other spaces of the building.
4.Close fireplace dampers.
5.Turn on clothes dryers and any appliance not connected to the venting
system. Turn on any exhaust fans, such as range hoods and bathroom
exhausts, so they are operating at maximum speed. Do not operate a
summer exhaust fan.
6.Follow the lighting instructions. Place the appliance being inspected
into operation. Adjust the thermostat so appliance is operating
continuously.
7.Test for spillage from draft hood equipped appliances at the draft
hood relief opening after 5 minutes of main burner operation. Use the
flame of a match or candle.
8.If improper venting is observed during any of the above tests, the
venting system must be corrected in accordance with the current edition
of National Fuel Gas Code, ANSI Z223.1/NFPA 54.
9.After it has been determined that each appliance connected to the
venting system properly vents when tested as outlined above, return
doors, windows, exhaust fans, fireplace dampers and any other
gas-fired burning appliance to their previous conditions of use.
The Chimney Adapter Kit is listed alternative venting system for these
furnaces. See the kit instructions for complete details.
This furnace is permitted to be vented into a clay tile-lined masonry
chimney that is exposed to the outdoors below the roof line, provided:
1. Vent connector is Type-B double-wall, and
2. This furnace is common vented with at least 1 draft hood equipped
appliance, and
3. The combined appliance input rating is less than the maximum
capacity given in Table 8, and
4. The input rating of each space heating appliance is greater than the
minimum input rating given in
Design Temperature. Chimneys having internal areas greater than
38 square inches require furnace input ratings greater than the input
ratings of these furnaces. See footnote at bottom of
5. The authority having jurisdiction approves.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.

If all of these conditions cannot be met, an alternative venting design
shall be used, such as the listed chimney adapter kit with these furnaces,
which are listed for use with the kit, a listed chimney-lining system, or a
Type-B common vent.
