• 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 by a qualified
person 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 meth-
od or in accordance with “ASHRAE Guide” or “Manual J-Load
Calculations” published by the Air Conditioning Contractors of
America.

WARNING
• 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.
Refer to
Vent/Flue Pipe and Combustion Air Pipe
-Termination Locations
for appropriate termination
locations and to determine if the piping system
from furnace to termination can be accomplished
within the guidelines given.
NOTE:
The length of
flue and/or combustion air piping can be a limiting
factor in the location of the furnace.
• Locate the furnace so condensate flows downwards
to the drain. Do not locate the furnace or its
condensate drainage system in any area subject to
below freezing temperatures without proper freeze
protection. Refer to
Condensate Drain Lines and
Trap
for further details.
•
Ensure adequate combustion air is available for the
furnace. Improper or insufficient combustion air
can expose building occupants to gas combustion
products that could include carbon monoxide. Refer
to
Combustion and Ventilation Air Requirements.
• Set the furnace on a level floor to enable proper
condensate drainage. If the floor becomes wet or
damp at times, place the furnace above the floor
on a concrete base sized approximately 1-1/2”
