• Can I install a Royall furnace if I live in town?
Royall indoor wood furnaces are a perfect fit for those close confined areas. Consider the height of the stack and always remember to comply with all state and local codes.


• How often do I need to clean out ashes?
Ash removal is extremely easy with our included ash pan. Our furnace is built with a separate access door for your safety in removing the ash while the unit is under load. It is important to clean out your ashes on a weekly or daily basis. The ash pan should be emptied as needed, every 4 days depending on heat load. At the end of the heating season, it is very important to clean out all ash deposits from the fire box. Cover the chimney to not allow moisture to enter into these areas. Moisture mixed with ash can create damage to the wood furnace.


•What Settings Should I Use For The Fan Limit Switch?
We recommend setting the fan limit switch to the following Settings, 160°,180°,200°. This tells the furnace, if it's internal temperature is below 160°, run the draft inducer fan until the internal heat is raised to 180°. At 180° the draft inducer fan will turn off until the internal temperature falls back to 160°. The final setting at 200° is for safety, if the system reaches this internal temperature everything will shut off due to excessive heat. You can modify these settings slightly depending upon your specific requirements. However, attempting to burn wood at a lower temperature range can lead to creosote buildup.


• How do I get technical support?
Technical Support is best offered by your local dealer. If you need additional assistance, you can find additional technical support for your wood furnace on our support page or by calling us at 800-944-2516 x.210

To order replacement parts, please contact your local dealer or view our online store at www.shoproyall.com.


• Are the controls on a Royall furnace complicated?
Absolutely not, Royall uses controls that are tried and true in the furnace industry.


• What is creosote and how can I reduce it?
When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form a nasty product referred to as creosote. The creosote vapors condense in the relatively cool chimney flue of a slow burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes a hot fire. The chimney connector and chimney should be inspected at least weekly by you to ensure everything is working correctly, and yearly by a professional to ensure proper operation and safety. If creosote has accumulated it should be removed to reduce the risk of a chimney fire. In the case of a chimney fire, Royall is not liable for damages to the furnace or your personal property.


• What's the best practice in burning wood in a Royall furnace?
Paper and kindling should be used for starting the fire. When loading your wood into your Royall furnace, the best practice is to load the wood towards the back of the furnace first and then towards the front. Royall recommends burning cut, split and dried seasoned hardwood. Do not overfill the unit so that hot coals fall out of the wood furnace when opening the fuel door. After burning wood in your furnace for a period of time, you will discover how much wood is needed per day and what types of wood burn best for you. Also look at the best burn practice for additional information.


• Can I use a Royall product with my existing forced air system in my house?
Absolutely, this is a common application of an indoor wood furnace. When installing your furnace do not forget a back draft damper. This allows your gas furnace to turn back on when your wood furnace gets low on fuel.
