Maintaining your System

Any solid fueled devices rely on an imperfect fuel source like wood or wood products like pellets, so they require an occasional “tune up” to improve their performance

Post-season cleaning and pre-season maintenance checks can help you avoid a system failure on the coldest day of the year. It can also help you avoid a frantic late-night call to your installer for a costly repair. Part of your Greenwood installer’s commitment to you is to ensure the proper care and operation of your Greenwood wood boiler and is often done with an annual maintenance or service agreement.

Periodic Maintenance

Wood boilers require removal of ash on a regular basis. When operated correctly, Greenwood Frontier Series systems will require ash removal as often as every several weeks up to once a month. Consult the owner’s manual for more details. 

Annual Maintenance

Have your Authorized Dealer perform full-system maintenance at least once a year, before the heating season. All wood heating appliance installations should have an annual chimney inspection. Follow recommendations of chimney sweep for cleaning.

When to Call your Installer!

It is critical that Greenwood products and replacement parts be installed and serviced by licensed, qualified Greenwood installers who have access to product data, service updates and training. As a manufacturer, we feel that it is in both our customers’ and our best interest to ensure that our product delivers the quality, durability, and comfort we advertise and you expect. Please contact your local Greenwood installer for assistance.

To facilitate the conversation with your Greenwood installer, please collect details of your Greenwood system, including: serial number, installation date, installation address, and details of the situation including pictures and/or sketches.


There are a number of steps an operator can take prior to contacting the dealer for assistance. The following is short checklist to follow if the system is not heating properly.

  • Check the firebox to see if there is adequate fuel and confirm that the firebox grate holes are not plugged with debris.
  • Check the boiler circulation pump. If it is not running, it may require repair or replacement.
  • Check heat transfer fluid level. If the level is low, inspect the piping for leaks and refill as directed per the owner's manual.
  • Check the flue to see if there are any blockages.
  • Check the induction blowers, dampers and motor for proper operation.

If you purchased your unit directly from Greenwood, our support team will require from you a completed Warranty Registration Card and a completed Service Request Form.
