935SB: Installation, Start-up, Operating and Service Maintenance Instructions
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 instructions.
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 allowable 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 garage must be
installed as specified in the warning box in the "Location" section.
9. The furnace is not permitted to be used for heating of buildings
under construction.
10. These
Upflow/Horizontal
design-certified for use with natural gas (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 and cannot be converted to propane gas.
11. For required clearances to combustible construction
Ensure sufficient clearance for furnace condensate trap installation.
See Location and Condensate Trap sections for required and
recommended clearances (see

*. Consult local building codes.
†. Additional clearance is required for condensate trap installation.
NOTE: Furnace edge contact is permissible with combustible materials
unless local codes state otherwise.
12. Maintain a 1-in. (25 mm) clearance from combustible materials to
supply air ductwork for a distance of 36 in. (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,
combustible tile, or any other combustible material other than wood
flooring. Special base is not required when this furnace is installed
on manufacturer's cased evaporator coils or when manufacturer's
evaporator coil casing is used. Clearance to combustible

IMPORTANT INSTALLATION AND START-UP
PROCEDURES
Failure to follow this procedure may result in a nuisance smoke or odor
complaint.
The manifold pressure, gas rate by meter clocking, temperature rise and
operation must be checked after installation. Minor smoke and odor
may be present temporarily after start-up from the manufacturing
process. Some occupants are more sensitive to this minor smoke and
odor. It is recommended that doors and windows be open during the
first heat cycle.
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury and/or
death.
Carbon Monoxide (CO) is a colorless, odorless, and tasteless poisonous
gas that can be fatal when inhaled. Follow all installation, maintenance,
and service instructions. See additional information below regarding
the installation of a CO Alarm.
Most states in the USA and jurisdictions in Canada have laws that
CSA
require the use of Carbon Monoxide (CO) alarms with fuel burning
products. Examples of fuel burning products are furnaces, boilers, space
heaters, generators, water heaters, stoves/ranges, clothes dryers,
fireplaces, incinerators, automobiles, and other internal combustion
engines. Even if there are no laws in your jurisdiction requiring a CO
2).
Alarm, it's highly recommended that whenever any fuel burning product
is used in or around the home or business that the dwelling be equipped
with a CO Alarm(s). The Consumer Product Safety Commission
recommends the use of CO Alarm(s). The CO Alarm(s) must be
installed, operated, and maintained according to the CO Alarm
manufacturer's instructions. For more information about Carbon
Monoxide, local laws, or to purchase a CO Alarm online, please visit the
following website. https://www.kidde.com
INTRODUCTION
NOTE: Downflow not permitted.
Fig. 2 – Upflow/Horizontal Orientations
This Upflow/Horizontal Category IV condensing furnace is CSA
design-certified as a direct-vent (2-pipe) furnace using outside air for
combustion. (see
Fig.
furnace using indoor air for combustion or air from a well-ventilated
attic or crawl space, where permitted by local code.
The furnace is factory-shipped for use with natural gas only and cannot
be converted to propane gas.
These furnaces are not approved for installation in recreational vehicles
outdoors, or in manufactured/mobile homes. When installed on a wood
floor, the furnace must be installed on a factory-supplied accessory
combustible floor base or evaporator coil casing.
