Code CSA C22.1
Recognize
safety information.
This is the safety-alert
symbol/_.
When
you
see this symbol
on the unit
and in instructions
or
manuals,
be alert to the potential
for personal
iniury.
Understand
the
signal
words
DANGER,
WARNING,
and
CAUTION.
These words
are used with the safety-alert
symbol.
DANGER
identifies
the most serious hazards
which will result in
severe
personal
iniury
or death.
WARNING
signifies
hazards
which
could
result
in personal
iniury
or death.
CAUTION

practices
which
may
result
in nfinor

or operation.
ENVIRONMENTAL
HAZARD
Failure
to follow
this caution
may result
in environmental
polution.
Remove
and recycle
all components
or materials
(i.e., oil,
refrigerant,
control boards,
etc.) before unit final disposal.
The 58MVC
Condensing
Gas-Fired
Furnaces
are CSA (formerly
AGA
and CGA)
design-certified
for natural
and propane
gases
(see furnace
rating
plate)
and for installation
in alcoves,
attics,
basements, closets, utility rooms, crawlspaces, and garages.
The
furnace is factory-shipped
for use with natural gas. A CSA listed
gas conversion kit is required to convert furnace for use with
propane gas.
See Fig. 3 for required clearances to combustibles.
Maintain a 1-in. (25 ram) clearance from combustible materials
to supply air ductwork for a distance of 36 inches (914 ram)
horizontally from the furnace.
See NFPA 90B or local code for
further requirements.
These furnaces SHALL NOT be installed directly on carpeting,
tile, or any other combustible material other than wood flooring.
These furnaces are suitable for installation in a structure built on
site or a manufactured
building completed
at final site. The
design of this furnace line is NOT CSA design-certified
for
installation in recreation vehicles, manufactured (mobile) homes
or outdoors.
This furnace is designed
for continuous
return-air
minimum
temperature of 60 °F (16 ° C) db or internfittent operation down to
55°F
(13°C)
db such as when used with a night setback
thermostat. Return-air temperature nmst not exceed 80 ° F (27 ° C)
db. Failure to follow these return air linfits may affect reliability
of heat exchangers, motors and controls. (See Fig. 4.)
These furnaces are shipped with the drain and pressure tubes
connected for UPFLOW applications.
Minor modifications are
required when used in DOWNFLOW,
HORIZONTAL
RIGHT,
or HORIZONTAL
LEFT
(supply-air
discharge
direction)
applications as shown in Fig. 1.
See details in Applications
section.
