Your  wood  furnace  is  a  high  efficiency  furnace  and  therefore  requires  little  maintenance.  It  is  important  to 

perform a visual inspection of the furnace every time it is emptied, in order to insure that no parts have been 

damaged, in which case repairs must be performed immediately. Inspect and clean the chimney and connector 

pipe periodically for creosote buildup or obstructions.

GASKET

It is recommended that you change the door gasket (which makes your furnace door air tight) once a year, in 

order to insure good control over the combustion, maximum efficiency and security. To change the door gasket, 

simply  remove  the  damaged  one.    Carefully  clean  the  available  gasket  groove,  apply  a  high  temperature 

silicone sold for this purpose and install the new gasket. You may light up your furnace again approximately 24 

hours after having completed this operation.  This unit’s feed door uses a 3/4” diameter rope gasket. This unit’s 

ash door uses a 1/2” diameter rope gasket.

PAINT

Only clean your furnace with a dry soft cloth that will not harm the paint finish.  If the paint becomes scratched or 

damaged, it is possible to give your wood furnace a brand new look by repainting it with a 1200° F heat resistant 

paint. For this purpose, simply scrub the surface to be repainted with fine sand paper, clean it properly, and apply 

thin coats (2) of paint successively.

AIR TUBES

The air tubes assembled in this unit are designed to provide an accurate mix of secondary air to insure the 

highest efficiency. Any damage or deterioration of these tubes may reduce the efficiency of combustion. The 

air tubes are held in position by either screws or snap pins. Locate these to either side of the tube and remove to 

allow the tube to be removed and replaced.

WARNING:

 Never operate the furnace without a gasket or with a broken one. Damage to the furnace or 

even house fire may result.
