The Toyotomi Extension Pipe Kit, part number 20476496, is designed for through-the-wall vent installations where the heater must be positioned farther from the exterior wall opening. This kit provides additional vent length to help achieve proper alignment while maintaining correct intake and exhaust flow.
What’s included (per Toyotomi kit contents): adjustable exhaust pipe with a telescoping range of 31-3/4" to 57", along with required connection components for extending the vent run.
Installation limits: total vent length for the intake and exhaust system must not exceed 10 ft, with a maximum of three bends in the system, including those at the heater. Extension kits may be combined as long as these limits are not exceeded.
Compatibility: Compatible with Toyotomi and Toyostove vented heater models that support modular extension pipe kits.
