!
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.
WARNING
!
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
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
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

INTRODUCTION

THE BLOWER IS LOCATED
TO THE RIGHT OF THE
BURNER SECTION, AND
CONDITIONED AIR IS
DISCHARGED TO THE LEFT.
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. 2). It is also certified as a non-direct vent (1-pipe)
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.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
NOTICE
THE BLOWER IS
LOCATED BELOW THE
BURNER SECTION, AND
CONDITIONED AIR IS
DISCHARGED UPWARD.
THE BLOWER IS
LOCATED TO THE LEFT
OF THE BURNER SECTION,
AND CONDITIONED AIR IS
DISCHARGED TO THE RIGHT.
This furnace is designed for minimum continuous return-air temperature
of 60°F (15°C) db or intermittent operation down to 55°F (13°C) db such
as when used with a night setback thermostat. Return-air temperature
must not exceed 80°F (27°C) db. Failure to follow these return-air
temperature limits may affect reliability of heat exchangers, motors, and
controls (see Fig. 3).

The furnace should be sized to provide 100 percent of the design heating
load requirement plus any margin that occurs because of furnace model
size capacity increments. None of the furnace model sizes can be used if
the heating load is less than half of the furnace model's output capacity.
Use Air Conditioning Contractors of America (Manual J and S);
American Society of Heating, Refrigerating, and Air-Conditioning
Engineers; or other approved engineering method to calculate heating
load estimates and select the furnace. Excessive oversizing of the
furnace may cause the furnace and/or vent to fail prematurely, customer
discomfort and/or vent freezing.
Failure to follow these guidelines is considered faulty installation and/or
misapplication of the furnace; and resulting failure, damage, or repairs
may impact warranty coverage.
For accessory installation details, refer to the applicable instruction
literature.
NOTE: Remove all shipping materials, loose parts bags, and literature
before operating the furnace
furnaces also contain an additional parts bag for the condensate trap, see
Condensate Trap section.
