WARNING: CARBON MONOXIDE POISONING HAZARD
Failure to follow instructions could result in severe personal
injury or death due to carbon-monoxide poisoning, if
combustion products infiltrate into the building.
Check that all openings in the outside wall around the vent
(and air intake) pipe(s) are sealed to prevent infiltration of
combustion products into the building.
Check that furnace vent (and air intake) terminal(s) are not
obstructed in any way during all seasons.
CAUTION:
Before heating season begins, a qualifi ed installer or service
agency must examine the furnace to ensure that:
1.
All fl ue gas carrying areas external to the furnace
(i.e. chimney, vent connector) are clear and free of
obstructions.
2.
The vent connector is in place, slopes upward and
is physically sound without holes or exccessive
corrosion.
3.
The return-air duct connection(s) is physically sound,
is sealed to the furnace cabinet, and terminates
outside the space containing the furnace.
4.
The physical support of the furnace is sound without
sagging, cracks, gaps, etc around the base so as to
provide a seal between the support and the base.
5.
There are no obvious signs of deterioration of the
furnace.
6.
The burner fl ames are positioned correctly by
comparing with pictorial sketches of the main burner
fl ame (see Section 12, Fig 42 in the Installation,
