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:
-
Seal any unused openings in venting system.
-
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.
-
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.
-
Close fireplace dampers.
-
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.
-
Follow the lighting instructions. Place the appliance being
inspected into operation. Adjust the thermostat so appliance is
operating continuously.
-
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.
-
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.
-
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.
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
7, 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, a listed chimney-lining system, or a Type-B common vent.
Inspections before the sale and at the time of installation will determine
the acceptability of the chimney or the need for repair and/or (re)lining.
Refer to the
Fig. 27
to perform a chimney inspection. If the inspection of
a previously used tile-lined chimney:
a. Shows signs of vent gas condensation, the chimney should be
relined in accordance with local codes and the authority having
jurisdiction. The chimney should be relined with a listed metal
liner, or a Type-B vent shall be used to reduce condensation. If a
condensate drain is required by local code, refer to the current
edition of NFGC NFPA54/ANSI Z223.1, Section 12.10 for
additional information on condensate drains.
b. Indicates the chimney exceeds the maximum permissible size in
the tables, the chimney should be rebuilt or relined to conform to
