Electronic Ignition Benefits: Unlike older pilot light systems, the electronic ignition eliminates gas waste, improves safety, and provides reliable startups every time. The system only uses gas when heating is actually needed, improving fuel efficiency.
Sealed Forced-Draft Combustion: The sealed combustion system draws outside air for combustion and safely exhausts combustion gases outside the RV. This prevents indoor air contamination and improves heating efficiency.
Low Electrical Draw: At just 7.5 amps on 12V, this furnace core is easy on your RV's electrical system and battery capacity. The efficient design minimizes power consumption while maximizing heat output.
The 30,000 BTU output is perfect for mid-size RVs (25-35 feet) and provides efficient heating for: β’ Travel Trailers: 25-35 foot models with standard insulation β’ Fifth Wheels: Mid-size models up to 32 feet β’ Motorhomes: Class B+ and smaller Class C models β’ Park Models: Seasonal RVs and tiny homes The ducted design distributes heat evenly throughout your RV, eliminating hot and cold spots common with space heaters.
Steel Gas Manifolds: Durable steel construction provides reliable gas distribution and long service life. The manifolds are precisely calibrated for optimal air/gas mixture and efficient combustion.
Quality Components: Every component meets Suburban's rigorous standards for RV applications. The heat exchanger, blower motor, and control systems are designed for the unique demands of mobile environments.
Made in USA Quality: Manufactured in Suburban's USA facility using American materials and craftsmanship. This ensures consistent quality, parts availability, and warranty support.
Professional Installation Required: Gas appliance installation must be performed by a qualified RV technician or gas appliance installer. Installation Steps: 1. Disconnect power and gas supply to existing furnace 2. Remove old furnace core from cabinet 3. Slide new core into existing cabinet 4. Reconnect gas, electrical, and duct connections 5. Test operation and check for leaks Tools Required: Standard gas appliance installation tools, gas leak detection solution, multimeter for electrical testing. Installation Time: Typically 2-3 hours for qualified technician.
Side or Bottom Duct Options: The core supports both side and bottom duct configurations, allowing flexibility for different RV floor plans and installation requirements.
Even Heat Distribution: The ducted design ensures consistent temperature throughout your RV. Heated air is distributed through ducts to floor registers or wall vents, eliminating cold spots and providing comfortable living conditions.
Quiet Operation: The efficient blower motor and well-engineered air flow paths minimize noise during operation. You'll enjoy comfortable heat without excessive fan noise.
Specific Model Compatibility: This 2613A core ONLY fits Suburban NT-30SP and NT-34SP furnaces.
