EXISTING VENT SYSTEMS

IMPORTANT RETROFIT
VENTING INSTRUCTIONS
If this furnace is a replacement installa-
tion, ALWAYS INSPECT the existing
vent system to be sure there are no
obstructions, blockages, or signs of cor-
rosion.
When the existing furnace is removed
from a venting system serving other
appliances, the venting is likely to be
too large to properly vent the remaining
attached appliances.
The following steps shall be followed
with each appliance that remains con-
nected to the common venting system,
while the other appliances that remain
connected to the common venting sys-
tems are not in operation.
NOTE: When the vent table permits
more than one diameter of pipe for a
connector or vent, the smallest per-
mitted diameter must be used.
1. Seal any unused openings in the
common venting system.
2. Visually inspect the venting system
for proper size and horizontal pitch
and determine that there is no block-
age, restriction, leakage, corrosion or
other deficiencies which could cause
an unsafe condition.
3. Insofar as is practical, close all build-
ing doors, windows and all doors
between the space where the appli-
ances remaining connected to the
common venting system are located.

DEDICATED VENTING THROUGH
CHIMNEY WITH "B-1" VENT
Turn on clothes dryers and any
appliance not connected to the
common venting system. Turn on
any exhaust fans, such as range
hoods and bathroom exhausts, so
they will operate at maximum
speed. Do not operate a summer
exhaust fan. Close fireplace
dampers.
4. Follow the lighting instructions.
Place the appliance being
inspected into operation. Adjust
the thermostat so the appliance
will operate continuously.
5. 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.
6. After it has been determined that
each appliance that remains con-
nected to the common venting
system properly vents (when test-
ed as outlined above) return
doors, windows, exhaust fans,
fireplace dampers and any other
gas-burning appliance to their
previous conditions of use.
7. If improper venting is observed
during any of the above tests, the
common venting system must be
resized. Refer to National Fuel
Gas Code, ANSI Z223.1 and/or
the Natural Gas Installation Code,
CSA-B149.1 & .2.
