Key Features
- Genuine OEM Shell Integrity — Manufactured to original housing tolerances, ensuring the lower cover seats flush and maintains proper enclosure of internal heater components.
- Drop-In Replacement — Mounts using the original attachment points on HI-series heater frames with no modification to the housing or fastener layout.
- Verified Fitment for HI-Series Heaters — Compatible with the HI110HD D, HI110D, and HI35 indirect-fired diesel air heaters.
- Protects Internal Components — A correctly fitted lower cover shields burner and fuel system components from debris, moisture, and physical damage during operation and transport.
- Combustion Safety Compliance — On indirect-fired heaters, a damaged or missing lower cover can compromise airflow paths and expose combustion components; replacing it promptly restores safe operating conditions.
The lower cover on an indirect-fired air heater forms the bottom section of the outer housing, enclosing and protecting the burner assembly, fuel system components, and heat exchanger from the surrounding environment. It plays a key role in directing airflow through the unit and preventing contaminants from interfering with combustion or mechanical parts. When the lower cover is cracked, missing, or damaged, the heater becomes vulnerable to operational faults and safety hazards, making prompt replacement essential for continued reliable use on the jobsite.
