58TP0B/58TP1B: Installation, Start-up, Operating and Service and Maintenance Instructions
CAUTION
!
PERSONAL INJURY AND/OR PROPERTY
DAMAGE HAZARD
Improper use or installation of this furnace may result in 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 casing, 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 55°F (13°C) and 80°F (27°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 venting according to
these installation instructions.
AIR FOR COMBUSTION AND VENTILATION
Provisions for adequate combustion, ventilation, and dilution air must be
provided in accordance with:
• U.S. Installations: Section 9.3 of the NFPA 54/ANSI Z223.1, Air for
Combustion and Ventilation and applicable provisions of the local
building codes.
WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury or death.
The operation of exhaust fans, kitchen ventilation fans, clothes dryers,
attic exhaust fans or fireplaces could create a NEGATIVE PRESSURE
CONDITION at the furnace. Make-up air MUST be provided for the
ventilation devices, in addition to that required by the furnace. Refer to
the Carbon Monoxide Poisoning Hazard warning in the venting section
of these instructions to determine if an adequate amount of make-up air
is available.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
The requirements for combustion and ventilation air depend upon
whether or not the furnace is located in a space having a volume of at
least 50 cubic feet per 1,000 BTUh input rating for all gas appliances
installed in the space.
• Spaces having less than 50 cubic feet per 1,000 BTUh require the
OUTDOOR COMBUSTION AIR METHOD.
• Spaces having at least 50 cubic feet per 1,000 BTUh may use the
INDOOR COMBUSTION AIR, STANDARD or KNOWN AIR
INFILTRATION METHOD.
Outdoor Combustion Air Method
1. Provide the space with sufficient air for proper combustion,
ventilation, and dilution of flue gases using permanent horizontal or
vertical duct(s) or opening(s) directly communicating with the
outdoors or spaces that freely communicate with the outdoors.
2.
Fig. 7
illustrates how to provide TWO OUTDOOR OPENINGS,
one inlet and one outlet combustion and ventilation air opening, to
the outdoors.
a. One opening MUST commence within 12 in. (300 mm) of the
ceiling and the second opening MUST commence within 12 in.
(300 mm) of the floor.
b. Size openings and ducts per
c. TWO HORIZONTAL DUCTS require 1 sq. in. (645 sq. mm) of
free area per 2,000 BTUh (1,100 mm2/kW) of combined input
for all gas appliances in the space per
d. TWO OPENINGS OR VERTICAL DUCTS require 1 sq. in.
(645 sq. mm) of free area per 4,000 BTUh (550 mm2/kW) for
combined input of all gas appliances in the space per
Table
2.
3. ONE OUTDOOR OPENING requires:
a. 1 sq. in. (645 sq. mm) of free area per 3,000 BTUh (734
mm2/kW) for combined input of all gas appliances in the space
per
Table 2
and
b. Not less than the sum of the areas of all vent connectors in the
space.
* Minimum dimensions of 3 in. (76 mm).
NOTE: Use any of the following combinations of openings: A&B, C&D, D&E, F&G
