Reznor 111848 Vent Cap
The Reznor 111848 Vent Cap is a critical 4-inch vertical terminal component engineered specifically for high-efficiency gas-fired unit heaters. As an OEM Reznor 4-inch vent cap, this part is designed to maintain the precise static pressure required for optimal combustion in Reznor UDAP, UDX, and UDBP models ranging from 30 to 125 MBH. In the field, using a generic "coolie" cap often leads to backdrafting or blockages; this unit heater vent cap features a robust, enclosed design that prevents moisture, debris, and avian intrusions from compromising your heat exchanger or tripping pressure switches during high-wind events.
For technicians performing a Reznor heater venting maintenance or gas heater vent cap replacement, the 111848 ensures a secure slip-fit connection to 4" single-wall or concentric vent systems. Properly installed HVAC exhaust vent caps are essential for preventing carbon monoxide buildup and protecting the internal cabinet from environmental damage. This heavy-duty replacement vent cap is built to withstand extreme thermal cycles and corrosive flue gases, ensuring the HVAC vent termination remains clear and functional across all seasons.
Key Benefits- OEM Precision: Guaranteed compatibility with Reznor UDAP, UDBP, and UDX gas-fired unit heaters sizes 30-125.
- Environmental Protection: Shields the system from rain, snow, and pests to prevent heat exchanger corrosion.
- Optimized Airflow: Maintains factory-spec ventilation to avoid nuisance trips from the pressure switch.
- Durable Construction: Engineered to handle high-temperature exhaust without warping or degrading.
What happens if the vent cap is blocked?
A blocked vent cap akan restrict flue gas flow, causing the unit’s pressure switch to open and shut down the burner for safety. It can also lead to dangerous backdrafting of combustion gases.
Can I use a standard rain cap from a hardware store?
Non-OEM caps often lack the required relief area and structural integrity for high-efficiency heaters. The Reznor 111848 is specifically sized for the 4-inch outlet to ensure correct venting physics.
Is this cap compatible with horizontal venting?
The 111848 is primarily utilized for vertical terminations. For horizontal side-wall venting, refer to the manufacturer’s specific CC6 vent kit requirements to ensure proper clearance and termination.
