1 2 | Bosch 96% AFUE Gas Furnace
WARNING: FIRE, INJURY OR DEATH HAZARD

When the furnace is installed in a residential garage, the
burners and ignition sources must be located at least 18
inches above the floor. The furnace must be located or
protected to avoid damage by vehicles. When the furnace is
installed in a public garage, airplane hangar, or other building
having a hazardous atmosphere, the furnace must be
installed in accordance with the NFGC. (See Fig. 6).
CAUTION: INJURY AND/OR PROPERTY DAMAGE HAZARD

Improper use or installation of this furnace may cause
premature furnace component failure. This gas furnace may
be used for heating buildings under construction provided
that:
—
The furnace is permanently installed with all electrical
wiring, piping, venting and ducting installed according
to these installation instructions. A return air duct
is provided, sealed to the furnace cabinet, and
terminated outside the space containing the furnace.
This prevents a negative pressure condition as
created by the circulating air blower, causing a flame
rollout and/or drawing combustion products into the
structure.
—
The furnace is controlled by a thermostat. It may not
be "hot wired" to provide heat continuously to the
structure without thermostatic control.
—
Clean outside air is provided for combustion. This is
to minimize the corrosive effects of adhesives, sealers
and other construction materials. It also prevents the
entrainment of drywall dust into combustion air, which
can cause fouling and plugging of furnace components.
—
The temperature of the return air to the furnace is
maintained between 60°F (16°C) and 85°F (29°C),
with no evening setback or shutdown.
—
The use of the furnace while the structure is under
construction is deemed to be intermittent operation
per our installation instructions.
—
The air temperature rise is within the rated rise range
on the furnace rating plate, and the gas input rate has
been set to the nameplate value.
—
The filters used to clean the circulating air during
the construction process must be either changed or
thoroughly cleaned prior to occupancy.
—
The furnace, ductwork and filters are cleaned as
necessary to remove drywall dust and construction
debris from all HVAC system components after
construction is completed.
—
Verify proper furnace operating conditions including
ignition, gas input rate, air temperature rise, and
Data subject to change
