The front wood door has two “U” bolts that are adjustable. If you feel the door is not closing
tightly or may be too tight, loosen the bolts with the door open and tighten or loosen the bolts
as necessary.
You should clean your ashes out at least once a week. A flat shovel works well for this job.
We recommend using a metal container of some kind to put the ashes in when removing
them. At the end of the season, be sure to completely clean the ash box. Ashes combined
with moisture are very corrosive and can eat through metal. Ash or coal corrosion is NOT
covered under warranty.
Your chimney is a 5” heavy wall rolled steel that sticks straight down into the fire box. Do not
worry about hitting it with wood. It should be cleaned about once a month. A 5” round
chimney brush will work for this job. You may use a chimney cap with the furnace to keep
rain out. It is recommended that you at least cover the chimney during the summer months
when the furnace is not in use to keep rain, birds and other insects from getting in the furnace.
The blower and damper blower can all be visually inspected and should only need replacing
when they quit working. They should last for several years however conditions are different at
every site and longevity may vary based on your climate and maintenance. Oil furnace door
hinges and the fire box front and back on the inside at the end of the season.
