SAFETY INSTRUCTIONS 
WARNING !
 THESE OPERATOR SAFETY INSTRUCTIONS SHOULD BE 
READ CAREFULLY! 
DO NOT DESTROY
PLEASE RETAIN FOR FUTURE REFERENCE 
1.  Fire door must be latched shut at all times when fire is 
burning. Open only to reload or check fire. 
2.  When reloading or checking fire, pull open bypass lever 
first, then open door very slowly. 
3.  All combustible material, including firewood
, must be a 
minimum of 460 mm (l8”) from unit. 
4.  Do not hang any combustible material above unit. 
5.  Burn wood only! 
6.  Do not use gasoline type lantern fuel, kerosene, charcoal 
lighter fluid or similar liquids to start or freshen up a fire in 
this heater. Keep all such liquids well away from the heater 
while it is in use. 
Chimney Fires
When wood heats up, wood gases and water vapor 
are given off. If these gases are not burned off in the 
stove, they condense in the stove pipes and chim-
ney. This buildup is called creosote. This usually hap-
pens when a heater is at low heat setting. At high 
heat settings most of the gases are burned. 
A chimney fire occurs when creosote in the chimney 
ignites, usually when the heater is turned up high 
after a period of low burn. 
Check your chimney pipe daily for creosote buildup 
until experience shows how often cleaning is neces-
sary. Running the heater wide open with bypass 
pulled out for 30 minutes periodically (about once a 
week) will minimize creosote buildup. If creosote 
buildup is 6 mm (1/4”) or more, clean or have the 
chimney cleaned mechanically. 
In the event of an uncontrolled chimney fire, shut the 
bypass damper and turn down the draft damper com-
pletely. (On thermostat models—turn down thermo-
stat). 
If chimney fire does not die down, keep a watch on 
fire and prepare to vacate the house. 
If needed, call the fire department. 
NOTE: 
1. Establish a routine for the storage of fuel, care of 
wood burner and firing technique. Be aware that dur-
ing mild weather and low heater temperatures, more 
creosote is deposited and more frequent cleanings 
are necessitated. 
2. All ARDENT ENERGY heating units are designed 
with double walled sides and insulated doors. This 
keeps the exterior of the units relatively cool. How-
ever, children must be taught to respect all wood 
burning appliances and not to play around or with 
them.
