(c) Where practical, close all building doors, windows, and
all doors between the space where the appliances
remain connected to the common venting system are
located and other spaces of the building. Turn on all gas
appliances not connected to the common venting sys-
tem and operate on high speed all exhaust fans (range
hoods and bathroom), except summer exhaust fans.
Close fireplace dampers.
(d) Following the lighting instructions, place the furnace
being inspected in operation. Adjust thermostat so
appliance will operate continuously.
(e) Test for spillage at the draft hood relief opening after 5
minutes of main burner operation. Use the flame of a
match or candle, or smoke from a cigarette, cigar, or
pipe.
(f) After it has been determined that each appliance re-
maining connected to the common venting system
properly vents when tested as outlined above, return
doors, windows, exhaust fans, fireplace dampers and
any other gas-burning appliance to their previous con-
ditions of use.
(g) If improper venting is observed during any of the above
tests, the common venting system must be corrected in
accordance with the latest edition of the National Fuel
Gas Code NFPA 54/ANSI Z223.1.
When resizing any portion of the common venting system,
use the appropriate table in Appendix G in the latest edition
of the National Fuel Gas Code NFPA 54/ANSI Z223.1.
Upflow or Horizontal units are shipped with the induced
draft blower discharging from the top of the furnace. (“Top”
is as viewed for an upflow installation.) The induced draft
blower can be rotated 90 degrees counterclockwise for
Category I venting, with the airflow horizontal left to right
(Figure 6). For horizontal installations, a four inch single
wall pipe can be used to extend the induced draft blower
outlet 1/2” beyond the furnace cabinet. Vent the furnace in
accordance with the National Fuel Gas Code NFPA 54/
ANSI Z223.1 - latest edition. In Canada, vent the furnace
in accordance with the National Standard of Canada, CAN/
CSA B149.1 and CAN/CSA B149.2 - latest editions and
