The Toyotomi Flue Pipe Extension, part number 20476486, is an adjustable venting component designed for select Toyotomi oil-fired heaters. This extension allows installers to increase the flue pipe length from 10 inches up to 18 inches, helping achieve proper vent termination when wall thickness, framing, or installation conditions require additional reach. Correct flue length supports proper exhaust flow and safe heater operation.
What’s included: one adjustable flue pipe extension (10"–18").
Installation limits: the flue pipe extension must be installed according to the heater manufacturer’s installation instructions and all applicable local venting codes. Only approved vent components should be used, and clearances, alignment, and termination requirements must be maintained to ensure safe operation.
Compatibility: Compatible with Toyotomi BS-36UFF (A and B versions) and OM-148 heater models.
