Direct vent (dual pipe) central forced air furnace in
which all combustion air supplied directly to the furnace
burners through a special air intake system outlined
in these instructions. Appropriate for use with natural
or propane gas ( NOTE: If using propane, a propane
conversion kit is required).
This furnace may be used as a construction site heater only
if all of the following conditions are met:
• The vent system is permanently installed per these
installation instructions.
• A room thermostat is used to control the furnace.
Fixed jumpers that provide continuous heating
CANNOT be used and can cause long term
equipment damage. Bi-metal thermostats, or any
thermostat affected by vibration, must not be used
during construction.
• Return air ducts are provided and sealed to the
furnace.
• A return air temperature range between 60ºF (16ºC)
and 80ºF (27ºC) is maintained.
• MERV 11 pleated minimum 4.0” thick (Example:
P/N AMP-11-2025-45) air filter(s) are installed in
the system and inspected daily and replaced as
needed during construction and upon completion of
construction.
• The input rate and temperature rise are set per the
furnace rating plate.
• The furnace must be installed as a two pipe system,
using 100% outside air for combustion during
construction.
• The furnace heat exchanger, components, duct
system, air filters and evaporator coils are thoroughly
cleaned following final construction clean up by a
qualified person.
• All furnace operating conditions (including ignition,
input rate, temperature rise and venting) are verified
according to these installation instructions.
• Furnace doors must be in place on the furnace while
the furnace is operating in any mode.
• Damage or repairs due to failure to comply with these
requirements are not covered under the warranty.
NOTE: The Commonwealth of Massachusetts requires that
the following additional requirements must also be met:
• Gas furnaces must be installed by a licensed plumber
or gas fitter.
• A T-handle gas cock must be used.
• If the unit is to be installed in an attic, the passageway
to and the service area around the unit must have
flooring.
To ensure proper furnace operation, install, operate
and maintain the furnace in accordance with these
installation and operation instructions, all local building
codes and ordinances . In their absence, follow the latest
edition of the National Fuel Gas Code (NFPA 54/ANSI
Z223.1), and/or CAN/CSA B149.1-15 Installation Codes,
local plumbing or waste water codes, and other applicable
codes.

The rated heating capacity of the furnace should be greater
than or equal to the total heat loss of the area to be heated.
The total heat loss should be calculated by an approved
method or in accordance with “ASHRAE Guide” or “Manual
J-Load Calculations” published by the Air Conditioning
Contractors of America.

LOCATION REQUIREMENTS &
CONSIDERATIONS
Follow the instructions listed below and the guidelines
provided in the Combustion and Ventilation Air Requirements
section when selecting a furnace location.
WARNING

personal injury or death, the following bullet points must
be observed when installing this unit.
WARNING
Possible property damage, personal injury or death due to
fire, explosion, smoke, soot, condensation, electrical shock
or carbon monoxide may result from improper installation,
repair operation, or maintenance of this product.
• Centrally locate the furnace with respect to the
proposed or existing air distribution system.
• Ensure the temperature of the return air entering the
furnace is between 55°F and 100°F when the furnace
is heating.
• Provide provisions for venting combustion products
outdoors through a proper venting system. Special
consideration should be given to vent/flue pipe routing
and combustion air intake pipe when applicable.
