Icp N9MP1 Condensing Gas Furnace User Manual

icp N9MP1 Condensing Gas Furnace Overview

The icp N9MP1 Condensing Gas Furnace is a 90+ AFUE, single-stage gas furnace designed for efficient home heating in a compact, multi-position cabinet. Built for indoor combustion air applications, it is a popular choice for homeowners who want reliable performance, lower fuel consumption, and flexible installation in upflow, horizontal, and select downflow configurations. As a condensing furnace, it captures more heat from combustion than standard non-condensing models, making it a strong fit for replacing older 80% furnaces in colder climates or upgrading a system for better energy savings.

This model line is known for its narrow cabinet design, durable heat exchanger construction, and compatibility with natural gas, with propane conversion kits available on many versions. Typical configurations include 40,000 to 125,000 BTUH input sizes, allowing contractors to match the furnace to small, medium, or larger residential spaces. The icp N9MP1 Condensing Gas Furnace is also valued for its straightforward serviceability, which appeals to HVAC technicians and homeowners seeking dependable long-term operation.

For most buyers, the estimated price range for the furnace alone is commonly in the mid-range residential category, while installed pricing depends on size, venting, duct modifications, and labor. Availability can vary by region and distributor, since this is typically sold through HVAC dealers, parts suppliers, and authorized installers rather than big-box retail channels.

Troubleshooting Common Problems on the icp N9MP1 Condensing Gas Furnace

Common issues include ignition failure, short cycling, pressure-switch lockouts, and restricted condensate drainage. If the furnace will not ignite, check the gas supply, thermostat settings, igniter condition, and flame sensor cleanliness. If the blower runs but heat does not start, a blocked vent, clogged condensate trap, or faulty pressure switch may be the cause.

• 2 flashes: Maximum recycle count exceeded; inspect ignition, gas flow, and airflow restrictions.
• 6 flashes: Soft lockout; reset power and check for repeated ignition failures.
• Continuous or repeated lockouts: Clean flame sensor, inspect wiring, and verify proper venting.
• Water near furnace: Clear condensate drain lines and confirm the trap is not blocked.

Preventive maintenance should include replacing filters regularly, cleaning the flame sensor, checking intake and exhaust piping, and keeping the condensate line clear. Warranty coverage and support typically depend on the installer and registration status, so keep the model and serial number available when seeking help. For assistance, contact a licensed HVAC technician, the installing dealer, or the manufacturer’s customer support channel listed on the unit label or owner documentation.
