Selkirk EF1 B Vent Flue Stack 18 in

The Selkirk EF1 B Vent Flue Stack is an 18-inch aluminium vent component designed for indirect-fired portable oil and kerosene torpedo heaters. It fits heater models HVF110, HVF210, HVF310 and HVF410 and provides a 6-inch vent diameter for proper exhaust routing.

Includes Rain Cap For Weather Protection

The bundled rain cap seals the top of the flue stack against rain and debris while the heater operates outdoors. This accessory prevents water from entering the vent pipe and protects the heater’s combustion chamber from moisture-related issues.

350 °F Maximum Operating Temperature

The stack is rated for a maximum operating temperature of 350 degrees Fahrenheit. Installers must verify that the heater’s exhaust temperature stays within this limit before using this flue stack.

Questions about this item

Will the 0.03 in aluminum wall need replacement after repeated 350 degree F cycles?

The 0.03 in aluminum construction is rated for a maximum operating temperature of 350 degrees F, matching the heater output limits.

Does the 6 in vent diameter restrict flow on the HVF410 during continuous firing?

The 6 in vent diameter matches the flue outlet on all compatible models including the HVF410, so flow capacity is maintained.

How hot does the rain cap get when the stack runs at 350 degrees F all day?

The aluminum stack and included rain cap operate at the heater's maximum 350 degrees F, so the cap reaches that temperature during sustained use.
