Toyotomi Extension Pipe Set (L)

The Toyotomi Extension Pipe Kit (L), part number 20479898, is designed for through-the-wall installations where the heater must be positioned farther from the flue outlet. Compatible with all Toyotomi and Toyostove models, this kit extends the venting system length for flexible placement while maintaining safe exhaust and air intake operation.

The Extension Pipe Kit (L) includes all components necessary for installation: an adjustable exhaust pipe (22-7/16" to 39-3/8"), a long exhaust extension pipe (39-3/8"), 80-inch intake pipe, two insulating cloth covers, pipe holders, support hardware, and an L-shaped exhaust joint. It allows a total telescoping length of 61-3/4" to 78-3/4".

Installation Notes: The total combined length of the air intake and exhaust pipes must not exceed 10 feet, and no more than three elbows (including those at the heater) may be used. Always ensure all exhaust components are properly sealed and covered with the included insulating material to maintain safe temperatures.
