The Toyotomi Pipe Stopper, part number 20474964, is a replacement sealing cap designed to block unused pipe openings in Toyotomi Toyostove heater installations for all models except OM-22. It provides a snug, heat-resistant closure that prevents drafts, debris, and combustion by-products from entering through an open port or vent connection when a particular pipe outlet is not needed. Manufactured to the original equipment specifications, it installs directly into the designated pipe opening without modification during maintenance or assembly.
This pipe stopper is intended for use when configuring or servicing a heater’s vent or internal piping system where an unused connection must be sealed to maintain proper airflow dynamics and safe operation. Keeping unused openings securely stopped helps support consistent combustion performance by reducing unintended air infiltration and helps maintain the designed draft characteristics within the heater. Installation should follow the applicable model’s service or installation instructions to ensure correct placement and secure seating of the stopper.
What’s Included: One (1) Toyotomi pipe stopper for all Toyostove heater models except OM-22.
Installation Limits: For replacement or installation use on specified Toyotomi Toyostove models; install with the heater powered off and ensure the stopper is fully seated to prevent drafts and maintain proper airflow.
Compatibility: Compatible with all Toyotomi Toyostove models except OM-22 requiring part number 20474964 to seal unused pipe openings.
