How often will I need to fill the Royall boiler?
Depending on the fuel you use your Royall boiler will dictate the amount of times needed to fill your wood boiler. Typically, you will refill the boiler twice a day in colder weather. Contact a dealer about typical fill rates for your area.


Can I install a Royall boiler if I live in town?
It's not recommended to install an outdoor wood boiler in a Metropolitan area, however, Royall indoor wood boilers are a perfect fit for those close confined areas. Consider the height of the smokestack 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 ash pan. Our ash pan 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. Never store your ash removal tray inside the boiler.


What Settings Should I Use For The Aquastat?
We recommend setting the aquastat to the following Settings, 180° with a 20° differential. This tells the boiler, 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°. 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.

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 industry and simple to operate.


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 boiler or your personal property.


What's the best practice in burning wood in a Royall boiler?
Paper and kindling should be used for starting the fire. When loading your wood into your Royall boiler, the best practice is to load the wood towards the back of the boiler 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 boiler when opening the fuel door. After burning wood or coal in your boiler for a period of time, you will discover how much wood is needed per day and what types of wood burn best for you.
