CARBON MONOXIDE POISONING HAZARD.
Carbon monoxide poisoning could result in death
from asphyxiation or serious bodily injury.
If you experience headaches, nausea, or
dizziness, carbon monoxide may be present.
Leave the house immediately and call your gas
supplier.
Combustion Air Checks
If any of the above signals are noticed, perform a combustion air
check or call a qualified service agency. If you add weather strip-
ping, storm windows, insulation, an additional fuel burning ap-
pliance, or remodel the structure, a combustion air check MUST
be accomplished after the addition.
Make the inspection as follows:
1. Close all doors and windows. If you have a fireplace, start a
fire and wait until flames are burning vigorously.
2. Turn on all exhausting devices, such as: kitchen and bath-
room exhaust fans and dryers (gas or electric).
3. Turn on all vented gas appliances, such as: heating equip-
ment (includes any room heaters) and water heaters.
4. Wait ten (10) minutes for drafts to stabilize.
5. On appliances with a draft hood, check for spillage by hold-
ing a lighted match 2" from the draft hood opening. Refer-
ence Figure 3, which shows a water heater draft hood.

If draft hood spillage is indicated:
1. Check for plugged vent connectors and chimneys. Repair
stoppage and test again.
2. Ifyou have a fireplace, open a windowor door near the fire-
place and then check for spillage.
If spillage stops, do not use the fireplace until you can sup-
ply fresh air by a permanent duct.
3. If you have kitchen and bathroom exhaust fans, turn them
OFF and check for spillage.
If spillage stops, do not use exhaust fans until you can sup-
ply fresh air by a permanent duct. Circuit breakers for fans
should be turned off and marked as to why they are off.
4. Spillage means air starvation and that an outdoor air duct
or air intake must be installed to provide air directly to the
area around the furnace. This duct or intake MUST comply
with local and state building codes or in their absence with
the National Fuel Gas Code NFPA 54/ANSI Z223.1-2002
in the U.S., or the National Standard of Canada, Natural
Gas and Propane Installation Code CSA B-149.1-00 in
Canada.
IndoorHumidity(YourComfort)
Relative humidity is important to your health. Proper humidifica-
tion helps cut down incidences of respiratory illness. Air that istoo
wet may damage the building structure. Air that is too dry is un-
comfortable. A quick way to test for proper humidity is as follows:
1,
2,
Look for frequent fogging or excessive condensation on
the inside of windows. This indicates the indoor humidity
level is too high for outdoor weather conditions.
Drop three ice cubes into a glass of water and stir. If, within
three minutes, moisture does not form on the glass, the air
is too dry and a humidifier would be beneficial. (Do not per-
form this test in the kitchen, cooking vapors may produce
inaccurate results.)
A good relative humidity is one just high enough to barely start
condensation along the lower edges or lower corners of the win-
dows, when it is cold outside. More than that can be damaging.
If the humidity is too high, try these suggestions to lower the hu-
midity:
A. Match flame pulls toward draft hood.
This indicates no spillage and that appliance is getting
enough air for combustion. Return exhausting devices and
appliances to the condition in which you found them.
B. Match goes out or flame wavers away from draft hood. This
indicates spillage and that appliance is not getting enough
air for combustion.
CARBON MONOXIDE POISONING HAZARD.
Carbon monoxide poisoning could result in death
from asphyxiation or serious bodily injury.
Draft hood spillage means there is not enough air
for proper combustion and carbon monoxide may
1. Reduce setting or discontinue use of humidifier.
2. Use range and bathroom exhaust fans while cooking and
bathing. Open a door or window for a few minutes to bring
in cool drier air.
3. Cook with pans covered.
4. Take shorter baths or showers with cooler water.
5. Install a fresh air intake duct. Cold, dry air brought in from
outside to the furnace area lowers the indoor humidity lev-
el.
6. Have appliances checked. A malfunctioning appliance can
contribute water vapor to the structure.
7. If the problem continues, consult a heating contractor
about adding a heat recovery ventilator or air-to-air heat
exchanger.
be present.
Keep a window open (a minimum of 2" ) near the
appliance until a permanent combustion air duct
is installed. Contact a qualified service agency.
