Page 11: Zone Heating And How To Make It Work For You
ZONE HEATING AND HOW TO MAKE IT WORK FOR YOU Your new WFP-75 wood fireplace is a space heater, which means it is intended to heat the area it is installed in as well as spaces that connect to that area, although to a lower temperature. This is called zone heating and it is an increasingly popular way to heat homes or spaces within homes. -

Page 13: Log Length
Pieces that are even slightly too long make loading the fireplace very difficult. The most common standard length of firewood is 16" (406mm). The WFP-75 will fit up to 20” wood. The pieces should be a consistent length, with a maximum of 1" (25 mm) variation from piece to piece. -

Therefore, allow each load of wood to burn down so that the space begins to cool off a little before loading. Letting the space cool before loading is one of the secrets to clean burning and effective zone heating. 4.3.7 SHUTTING DOWN THE AIR SUPPLY HearthStone Quality Home Heating Products, Inc ® WFP-75 Model 8411... -
