2040 Non-Catalytic / Catalytic Wood Burning Stove

30005295

No single air control setting will fit every situation.  Each 

installation will differ depending on the quality of the fuel, the 

amount of heat desired, and how long you wish the fire to 

burn; outdoor air temperature and pressure also affect draft.   
The control setting also depends on your particular instal-

lation’s “draft,” or the force that moves air from the stove 

up through the chimney.  Draft is affected by such things 

as the length, type, and location of the chimney, local ge-

ography, nearby obstructions, and other factors. See Page 

26 for details on how the installation affects performance.
Too much draft may cause excessive temperatures in the 

Encore

®

, and could even damage the stove. On the other 

hand, too little draft can cause backpuffing into the room 

and/or the “plugging” of the chimney.
How do you know if your draft is excessively high or low?  

Symptoms of too much draft include an uncontrollable 

burn or a glowing-red stove part. Signs of weak draft are 

smoke leaking into the room through the stove or chimney 

connector joints or low heat output.
In some newer homes that are well-insulated and weath-

er-tight, poor draft may result from an insufficient air supply 

in the house.  In such instances, an open window near the 

stove on the windward side of the house can provide the 

combustion air supply needed.  
Another option for getting more combustion air to the stove 

is to duct air directly from outside to the stove.  In some 

areas provisions for outside combustion air are required 

in all new construction.
The Encore

®

 is equipped to deliver outside air for combus-

tion and outside air kit #3265 is available.   
When first using the stove, keep track of the air control 

settings. You will quickly find that a specific setting will give 

you a fixed amount of heat. It may take a week or two to 

determine the amount of heat and the length of burn you 
should expect from various settings.
Most installations do not require a large amount of combus-

tion air, especially if adequate draft is available.  

Do not for 

any reason attempt to increase the firing of your heater 

by altering the air control adjustment range outlined 

in these directions.

Use the following air control settings as a starting point to 

help determine the best settings for your installation.  Each 

is described as a fraction of the total distance the lever may 

be moved from right to left.

 Take temperature readings with a thermometer located 

in the middle of the griddle.

Surface Thermometer is a 

Valuable Guide to Operation

An optional surface thermometer tells you when to adjust 

the air control, and when to refuel. (Fig. 36)

For example, when the thermometer registers at least 

450°F. (230°C) after start-up you know the stove is hot 

enough and it may be time to close the damper.  Note that 

the stove will warm up much sooner than the chimney, 

though; a warm chimney is the key to easy, effective stove 

operation. Please review the draft management information 

on Page 27 to see how the size, type, and location of your 

chimney will affect your stove operation. When thermom-

eter readings drop below 350°F. (175°C) it’s time to adjust 

the air control for a higher burn rate or to reload the stove.  

A temperature reading over 650°F. (340°C) is a sign to 

reduce the air supply to slow the burn rate.
Use the following temperature ranges as a guide:

• 

Readings in the 350°-500°F. (175°-260°C) range indi-

cate low to medium heat output.  

• 

500°-600°F. (260°-315°C) readings indicate medium 

heat output.  

• 

Readings of 600°-650°F. (315-340°C) indicate high heat 

output.  Operating your Encore

®

 continuously at griddle 

temperatures higher than 650° F (340°C) may damage 

the cast iron or enamel finish.

Your stove is equipped with a temperature probe which 

shows the operating range of the catalytic combustor.  

This is located on the back of the stove and is viewed 

from the top.  If the probe indicator is below the operate 

catalyst range, add fuel or open the bypass damper too 

allow the fire to build.  Closing the bypass damper should 

then result in an increase in catalyst temperature to within 

the operate catalyst range.
If the probe indicator is above the operate catalyst range, 

the catalytic combustor is running to hot and may be dam-

aged.  In many cases, increasing the primary air can re-

duce the catalyst temperature and adding less wood with 

each loading can also help if overheating is persistent.  

Overly dry wood can also cause overheating of the cata-

lyst element.  Do not add wood to the stove if the probe 

reads above the operate catalyst range.
