Keep a verified part number on hand to ensure you receive the correct cap for your specific unit.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional standards as the original, ensuring the cap seats and seals correctly on the exhaust or intake stack.
- Direct-Fit Replacement — Engineered to drop into the existing mounting point on HIF690 series heaters without reworking or adapting the surrounding hardware.
- Broad HIF690 Series Coverage — Compatible across the HIF690 Flameless Air Heater family, including Kubota engine-equipped variants, covering multiple build configurations in a single part number.
- Weather and Debris Protection — Properly functioning rain cap keeps moisture, wind-driven debris, and backflow out of the heater stack, maintaining clean combustion airflow and consistent heat output.
- Combustion Safety Relevance — A damaged or missing rain cap on a flameless heater can allow water ingestion or airflow disruption; replacing it with a correct OEM part helps maintain safe operating conditions on the jobsite.
A rain cap sits at the top of a heater's exhaust or air intake stack and acts as a weather shield, deflecting rain, snow, and wind away from the opening so that airflow through the heater remains unobstructed. On flameless air heaters like the HIF690, consistent and uninterrupted airflow is critical to maintaining the catalytic heating process that produces clean, flame-free heat. When the cap is cracked, missing, or poorly fitted, water can enter the stack, disrupting combustion performance and potentially triggering safety shutdowns or causing internal corrosion over time.
