Flue Storage Cap That Seals the Flue When the Heater Is Off
The Frost Fighter flue storage cap is a solid 6 in. flue cap for storage that seals the pipe shut while the heater is off. A parked heater with an open flue takes rain, dust, and insects into the pipe and heat exchanger. Left uncapped between jobs, it collects rust and debris that block airflow on the next start. Remove it before operating.
Key Features and Benefits
- The Frost Fighter flue storage cap is a solid cover with no louvers. Unlike the 48808 rain cap, which lets exhaust through while the heater runs, this flue cover seals the opening completely.
- The 6 inch flue cap fits the same 6 in. outlet on every IDF and IDH heater. No adapter or reducer is needed.
- A heater storage cover keeps the heat exchanger dry and the pipe clean between jobs, through transport, and over off-season storage.
- This flue storage cap must be removed before the heater operates. A solid cap left on during operation blocks exhaust.

Frequently Asked Questions
Do I need a cap on my heater flue when not in use?
Yes. An uncapped flue lets rain, dust, and animals into the pipe and heat exchanger. The Frost Fighter flue storage cap seals the 6 in. opening while the heater sits idle. Remove it before the next start.
Flue storage cap vs rain cap: what is the difference?
The flue storage cap (48808A) is solid and closes the pipe when the heater is off. The rain cap (48808) has louvers and stays on while the heater runs. Never operate a heater with the storage cap in place.
How to protect heater flue during storage?
Fit a flue cap for storage over the 6 in. outlet once the heater has cooled. Keep the unit under cover if possible. Inspect the flue pipe for damage or nesting before the next season.
How to store a portable heater between jobs?
Shut it down, let the flue cool, and fit a heater flue cover over the outlet. Store the unit on level ground away from traffic. Inspect the hose, flue, and duct connections before each restart.
What happens if you leave heater flue open?
Rain, dust, and insects enter the pipe and settle in the heat exchanger. By the next start, buildup causes rust and blocked airflow. Fit the 48808A whenever the heater is off.
