Description

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.

Product FAQs:

Q. What is the Toyotomi 20479897 Exhaust Extension Pipe Set (M) used for?

A. This medium-length extension kit is designed for through-the-wall installations where the heater needs to be positioned farther from the flue outlet. It allows flexible placement while maintaining proper air intake and exhaust balance.

Q. What is the telescoping range of the (M) kit?

A. The exhaust pipe in the (M) kit telescopes from 22-1/2" to 39-3/8", allowing easy adjustment to fit different wall distances or heater placements.

Q. Can I combine the short, medium, and long extension pipe kits?

A. Yes. The Toyotomi short (S), medium (M), and long (L) extension pipe sets are designed to fit together. They can be combined as needed, provided the total vent run does not exceed 10 feet (120 inches) and no more than three bends are used in either the intake or exhaust line.

Q. How many elbows or bends are allowed in the venting system?

A. Toyotomi limits the system to a maximum of three bends or elbows in the air intake and exhaust piping combined. Exceeding this limit can restrict airflow and affect performance.

Q. Which models are compatible with the 20479897 (M) kit?

A. The 20479897 Exhaust Extension Pipe Set (M) is compatible with all Toyotomi and Toyostove Laser and Oil Miser vented heater models.

Q. What components are included in the kit?

A. The kit includes a telescoping exhaust pipe (22-1/2"–39-3/8"), 80" air intake pipe, L-joint, two insulating cloth covers, pipe holders, and necessary mounting hardware.

Q. Any installation recommendations?

A. Always maintain proper sealing and insulation on exhaust components. Ensure total vent length stays within 10 feet, and use a gentle slope toward the exterior termination for moisture drainage. Follow Toyotomi installation guidelines and local codes for best results.
