H6.1
1. Use this furnace only with type of gas approved for this furnace. Refer to the furnace rating plate.
2. Install this furnace only in dry indoor locations (protected from weather).
3. Provide adequate combustion and ventilation air to the furnace space as specifi ed in Section 7 of this
manual, “Ventilation and Combustion Piping.”
4. Combustion products must be discharged outdoors. Connect this furnace to an approved vent system only,
as specifi ed in Section 7 of this manual, “Venting and Combustion Piping.”
5. Never test for gas leaks with an open fl ame. Use a commercially available soap solution made specifi cally
for the detection of leaks to check all connections as specifi ed in Section 12 of this manual, “Gas Supply
and Piping.”
6. Always install furnace to operate within the furnace’s intended temperature-rise range with a duct system,
which has an external static pressure within the allowable range, listed on the furnace rating plate, and as
specifi ed in Sections 3, 6, and 18 of this manual, “Furnace Sizing,” “Ductwork,” and “Airfl ow.”
7. When a furnace is installed so that the supply ducts carry air circulated by the furnace to areas outside the
space containing the furnace, the return air shall also be handled by duct(s) sealed to the furnace casing and
terminating outside the space containing the furnace. (Furnace for heating the home located in the attached
garage, for example).
8. A gas-fi red furnace for installation in a residential garage must be installed so that the burners and ignitor
are no less than 18” (457 mm) above the fl oor. The furnace must be located, or protected to avoid physical
damage by vehicles. (See safety warning).
9. This furnace may be used for heating of buildings or structures under construction provided that:
• The furnace is permanently installed with all electrical wiring, piping, venting and ducting installed per
these installation instructions.
• A room thermostat must control the furnace. The use of fi xed jumpers that will provide continuous
heating is not allowed.
• The return air duct must be provided and sealed to the furnace casing, and terminate outside the
space containing the furnace.
• Return air temperature range between 55°F (13°C) and 80°F (27°C) must be maintained.
• Air fi lters must be installed in the system and must be maintained during construction.
• Air fi lters used to clean the circulating air during the construction process must be either replaced or
thoroughly cleaned prior to occupancy.
• The input rate and temperature rise must be set per the furnace rating plate.
• One hundred percent (100%) outdoor air must be provided for combustion air requirements during
construction. This is to minimize the corrosive effects of adhesives, sealers and entrainment of
drywall dust into combustion air, which can cause fouling and plugging of furnace components.
• The furnace heat exchanger, components, duct system, and evaporator coils must be thoroughly
cleaned following fi nal construction clean-up.
• All furnace operating conditions (including ignition, input rate, temperature rise and venting) must be
verifi ed according to these installation instructions.
