Product Usage Instructions

1. Ensure the furnace is installed in an up-flow or horizontal position according to your requirements.
2. Connect the appropriate gas supply to the furnace, using the specified pipe connection size of 1/2 inch.
3. If using natural gas, install four main orifices with a drill size of 45. If using propane gas, install four main orifices with a drill size of 56.
4. Make sure the vent outlet diameter is a minimum of 2 inches round.
5. Connect the inlet air with a minimum diameter of 2 inches round.
6. Ensure the power connection is made according to the specified voltage, phase, and frequency (120 / 1 / 60).
7. Provide proper overcurrent protection with a maximum amperage of 15 amps.
8. Refer to the provided airflow tables for heating and cooling settings.
9. Make sure to comply with local codes and regulations during installation.

• (a) Factory Setting.

General Features

• NATURAL GAS MODELS
  Central Heating furnace designs are certified by the American Gas Association for both natural and L.P. gas. Limit setting and rating data were established and approved under standard rating conditions using American National Standards Institute standards.

• SAFE OPERATION
  The Integrated System Control is a solid-state device that continuously monitors for the presence of flame when the system is in the heating mode of operation. A dual solenoid combination gas valve and regulator provide additional safety.

• QUICK HEATING
  Durable, cycle tested, heavy gauge tubular stainless steel primary heat exchanger quickly transfers heat to provide warm conditioned air to the structure. Low energy power vent blower, to increase efficiency and provide a positive discharge of gas fumes to the outside.

• BURNERS
  Multiport Inshot burners will give years of quiet and efficient service. All models can be converted to L.P. gas with an LP conversion kit.

• INTEGRATED SYSTEM CONTROL
  An exclusively designed operational program provides total control of furnace limit sensors, blowers, gas valves, and flame control and includes self- diagnostics for ease of service. Also contains dry contacts for EAC and HUM.

• ENERGY-EFFICIENT OPERATION
  The furnace is certified by the manufacturer to leak 1.4% or less of nominal air conditioning CFM delivered when pressurized to a .5″ water column with all inlets, outlets, and drains sealed.

• AIR DELIVERY
  The variable-speed blower motor has sufficient airflow for most heating and cooling requirements and will switch from heating to cooling speeds on demand from the room thermostat.

• SECONDARY HEAT EXCHANGER
  The furnace has a special type 29-4C™ stainless steel secondary heat exchanger to reclaim heat from flue gases which would normally be lost.

• STYLING
  Heavy gauge steel and “wrap-around” cabinet construction are used for strength. Every orientation has at least two venting options. There are no knockouts on the cabinet.

• FEATURES AND GENERAL OPERATION
  The furnace utilizes a Silicon Nitride Hot Surface Ignition system, which eliminates the waste of a constant burning pilot. The integrated system control lights the main burners upon demand for heat from the room thermostat. Complete front service access.

  • Low-energy power venter
  • Vent proving pressure switches.

Features and Benefits

• 96.0% AFUE ACROSS ALL MODELS

  • Meets utility rebates
  • Lowers utility bills

• ELECTRICALLY EFFICIENT
  Efficient airflow design reduces electrical energy use

• 34 INCH TALL

  • Lighter, easier to move, and fit into tight spaces like short basements or tight closets
  • Works great with larger, high-efficiency coils
  • No knockouts

• 3–WAY MULTI-POISE / DEDICATED DOWNFLOW

  • 6 SKU’s —Upflow / Horizontal Left / Horizontal Right
  • 5 SKU’s —Downflow
  • Added application flexibility and reduction in specification errors

• AIRFLOW
  At least 400 CFM/ton at 0.5 in. H20 external static pressure; set airflow options down to 290 CFM/ton

• REGULATORY

  • All models are air-tight; 1.4% or less air leakage as per ASHRAE 193
  • Open vestibule design provides a full 34” high open vestibule

• DIMENSIONS

  • Width is industry standard: 21”
  • Depth remains approximately 28”
  • The cabinet will be compatible with industry-standard coils, as well as, other accessories

• INTEGRATED FURNACE CONTROL

  • Setup/Status/Diagnostics/Digital Display
  • No dip switches
  • The last six errors stored
  • Dry contact EAC and HUM connections
  • All Molex connections; no spade terminals
  • Low voltage labeled above and below
  • Rain shield over IFC keeps condensate off the control

• TUBULAR STAINLESS STEEL PRIMARY HEAT EXCHANGER 29–4C STAINLESS STEEL SECONDARY HEAT EXCHANGER

  • Stainless steel is a more durable, corrosive-resistant material than aluminized steel
  • Integrated rail system for easy access if required
  • Reduces or eliminates the need for baffles

• VARIABLE SPEED BLOWER MOTOR

  • Increased efficiency
  • Improved home comfort

• THREE–WAY MULTI-POISE (UPFLOW, HORIZONTAL LEFT AND RIGHT) PLUS DEDICATED DOWNFLOW

  • Easier to specify
  • Shipped ready to install (no kits required)
  • Every model has at least two venting options
  • When horizontally, the trap extends only about 2”
  • Barbed fitting on the trap at the hose connection and on the cabinet transition for the hose has barbed fitting and clamps at both ends for leak resistance.
  • Vent table improvements including longer vent lengths; 2” pipe can be used up to 100K
