Page 5: Safety Rules For Operating Your Fireplace
SAFETY RULES FOR OPERATING YOUR FIREPLACE • Use only a HearthStone glass door, specifically designed for the model WFP-75. • When cleaning the fireplace, the ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a non-combustible floor or on the ground outside the house, pending final disposal. - Page 6 We also recommend that you register your warranty online at: http://www.hearthstonestoves.com/customer-resources/ warranty-registration Registering your warranty online will help us track rapidly the information we need on your unit.

2. • The WFP-75 is not intended for use with a gas log. Failure to follow these instructions will void the certification and the warranty of the fireplace and may result in an unsafe installation. -
Page 8: Operating The Wfp-75
2.2 OPERATING THE WFP-75 2.2.1 Fuel The WFP-75 is designed to work best when fuelled with seasoned cordwood. Use solid wood or processed solid fuel fire logs only*. Hardwoods are preferred to softwoods since the energy content of wood is relative to its density. Hardwoods will result in a longer burning fire and less frequent refuelling. -
Page 9: First Fires
Your WFP-75 fireplace will work best if a thick bed of hot embers is maintained in the bottom of the firebox and a minimum of two large pieces of seasoned fuel are added. Combustion efficiency is largely related to establishing a hot ember bed and hot firebox temperatures. -
Page 10: Primary Air
2.2.6 Primary Air There is no flue damper in the WFP-75. As is common with air tight stoves, the combustion air control sets the flow of air entering the firebox. This allows for a more precise control of the fire. -
Page 11: Combustion Settings
Creosote may accumulate on the glass door. This method of burning should be used only after operating the WFP-75 with the air control opened to produce a hot fire for about an hour or at medium pace for at least 2 hours. Slow combustion can be used at night in order to reduce the heat output and to prolong the burn. -
Page 12: Negative Pressure In The House
5. Do not abuse the unit by burning paper, or cardboard or construction material such as pressed wood, plywood or lumber. 6. Do not allow the wood to smoulder or burn without flame, since this will produce excessive creosote in the unit. Hearthstone Quality Home Heating Products, Inc ® WFP-75 Model 8410... -
Page 13: Maintaining Your Wfp-75
1. Remove the front air tube by pulling out the cotter pin on the side of the tube. They are located at the top, underneath the baffle. 2. Lift the baffle assembly and slide it out of the fireplace. You now have access to the chimney. Hearthstone Quality Home Heating Products, Inc ® WFP-75 Model 8410... -

If the ashes are disposed of by burial in soil or otherwise locally dispersed they should be retained in the closed container until all cinders have thoroughly cooled. Hearthstone Quality Home Heating Products, Inc ® WFP-75 Model 8410... -

2.3.7 Glass Care – Replacement The glass used in the WFP-75 is 5 mm thick of dimension: 13.65” x 25.30” and tested to reach temperatures up to 1400º F. If the glass breaks, it must be replaced with one having the same specification. -
Page 16: Glass Care - Cleaning
Figure 4 2.3.8 Glass Care – Cleaning The WFP-75 is designed to keep the glass clean under normal operating conditions. If the WFP-75 is operated continuously with the combustion air controls closed, the glass will tend to get dirty unless the fuel, firebox and glass are maintained at higher temperatures. To clean the glass, there are a number of specially designed cleaners. -
