IMPORTANT: Every possible circumstance
that might involve a hazard cannot be

and on tags or decals affixed to the unit
are therefore not all-inclusive. If a proce-
dure, work method, or operating tech-
nique not specifically recommended by
Dayton is used, you must make sure it is
safe for you and others. You should also
ensure that equipment will not be
damaged or made unsafe by the operating
or maintenance method you choose.
Carbon monoxide
poisoning: Some
people are more affected by carbon
monoxide than others. Early signs of
carbon monoxide poisoning resemble
the flu, with headaches, dizziness,
and/or nausea. If you have these signs,
the heater may not be operating
properly. Get fresh air at once! Have
heater serviced.
Natural Gas: Natural gas has a distinc-
tive odor. This odor helps you detect a
natural gas leak. However, the odor
may fade. Natural gas may be present
even though no odor exists.
