Greenfield Installation and Operations Manual

Page 8

Figure 2

There are two burn systems used in the Hastings/Greenfield models. These systems are
interchangeable in the stove body. This Manual covers the

GREENFIELD

, which uses the

Multi-Fuel Burn System

The

Multi-Fuel Burn System

is the St. Croix Patented

“Clinker Removal System”.

This burn

pot allows the clinker to be removed without losing the fire in the pot. This eliminates the need
of having to re-light the Greenfield after removing the clinker.

This burn system does not have

Self-Ignition.

It is approved for Corn, Wheat, Rye, Cherry Pits & Distillers Grain. Wood pellets

are no longer approved for use (except as starter pellets) in Greenfield’s built after the 2015
NSPS.
