1. Use only with type of gas approved for this furnace.
Refer to the furnace rating plate.
2. Install this furnace only in a location and position as
specified in the "Location" section of these instructions.
3. Provide adequate combustion and ventilation air to the
furnace space as specified in "Air for Combustion and
Ventilation" section.
4. Combustion products must be discharged outdoors.
Connect this furnace to an approved vent system only,
as specified in the "Venting" section of these instruc-
tions.
5. Never test for gas leaks with an open flame. Use a
commercially available soap solution made specifically
for the detection of leaks to check all connections, as
specified in the "Gas Piping" section.
6. Always install furnace to operate within the furnace's
intended temperature−rise range with a duct system
which has an external static pressure within the allow-
able range, as specified in the "Start−Up, Adjustments,
and Safety Check" section. See furnace rating plate.
7. When a furnace is installed so that supply ducts carry
air circulated by the furnace to areas outside the space
containing the furnace, the return air shall also be
handled by duct(s) sealed to the furnace casing and
terminating outside the space containing the furnace.
See "Air Ducts" section.
8. A gas−fired furnace for installation in a residential gar-
age must be installed as specified in the warning box in
the "Location" section.
9. The furnace may be used for construction heat
provided that the furnace installation and operation
complies with the first CAUTION in the LOCATION sec-
tion of these instructions.
10. These Multipoise Gas−Fired Furnaces are CSA
(formerly A.G.A. and C.G.A). design−certified for use
with 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 accessory gas conversion kit is required to
convert furnace for use with propane gas.
11. See Figure 2 for required clearances to combustible
construction.
12. Maintain a 1−in. (25 mm) clearance from combustible
materials to supply air ductwork for a distance of 36
inches (914 mm) horizontally from the furnace. See
NFPA 90B or local code for further requirements.
13. These furnaces SHALL NOT be installed directly on
carpeting, tile, or any other combustible material other
than wood flooring. In downflow installations, factory
accessory floor base MUST be used when installed on
combustible materials and wood flooring. Special base
is not required when this furnace is installed on manu-
facturer's coil model numbers END4X, ENW4X or coil
casing model number NAEA. See Figure 2 for clear-
ance to combustible construction information.
