HEAT EXCHANGER TUBES 

 

ENSURE STOVE IS COLD BEFORE CLEANING HEAT EX-

CHANGE TUBES.  

 

Remove fly ash from heat exchange tubes as follows: 

 

1.  Ensure the door is secured closed.  

2.  Open the hopper lid (see 

Pellet Fuel Hopper

, page 17). 

3.  Using the hole in the handle of the grate scraper tool,  “grab” 

onto the heat exchange rake handle located above the door 

(in the center).   

4.  Pull the grate scraper tool back and forth several times (up-

ward and forward, then back) to rake a way fly ash from the 

heat exchange tubes. 

 

Note: If a more thorough cleaning of heat exchange tubes is de-

sired, the baffle plate in front of the tubes can be easily removed 

(slide baffle plate forward until screw heads clear the notches on 

each side, then remove baffle).  With baffle plate removed, use a 

small brush to clean between tubes (see pages 27 and 30, item 

#30). 

 

Removing Fly Ash from Heat Exchange Tubes 

 
 
 

 

 

 

Recommended Frequency of 2 days – 2 weeks 

 

DOOR ROPE GASKET

 

The condition of the rope gasket around the door 
and windows should be checked periodically and 
replaced or repaired if necessary.  A strip of pa-
per or a paper bill (i.e. one-dollar bill) may be 
used to perform a test of the integrity of the door 
seal.  Close the door on the paper in several dif-
ferent locations and pull.  It is normal to feel only 
a slight amount of friction.  The door gasket does 
not need to be “tight” in all area since a small 
amount of air drawn into the stove around the 
gasket is not hazardous or detrimental to the per-
formance of you stove.   
 

Check seal with paper strip or dollar bill 

(Front view of stove) 

 

 

As a minimum, check seal at points indicated 

below (Inside view of door) 

 

 

 

Recommended Frequency of 1 year
