Toyotomi Extension Pipe Set (M)

The Toyotomi Extension Pipe Set (M), part number 20479897, is designed for through-the-wall installations when the heater must be positioned farther from the vent outlet. The telescoping exhaust section adjusts from 22-7/16" to 39-3/8" for precise placement while maintaining proper intake and exhaust flow.

What’s included (per Toyotomi kit contents): adjustable exhaust pipe (22-7/16"–39-3/8"), 40" intake pipe, 40" insulating cloth cover, pipe holder, two sets of pipe support hardware (holder/holder support, screw, wood screws, nut), and an L-shaped exhaust joint.

Installation limits: total run for each line (air intake and exhaust) must not exceed 10 ft, and the system may use no more than three bends/elbows including those at the heater. The S, M, and L extension kits are modular and may be combined, provided these limits are not exceeded.

Compatibility: All Toyotomi and Toyostove Laser and Oil Miser vented heater models.
