WARNING:  IT IS VERY IMPORTANT THAT YOU OB-

 

There are listed clearances for your fireplace insert 

which were determined in a Laboratory testing and must 

be maintained. 

 

Minimum Clearance to Combustibles 
 

Stove top to mantel: 

 

31" / 787 mm 

 

Stove top to trim:    

 

9" / 229 mm 

 

Stove side to trim: 

  

1" / 25 mm 

 

Stove side to sidewall: 

  

9" / 229 mm 

 
 
 

 

 

 

RAISED HEARTH 
Note: Using a heat defector on the surround, does not reduce 
clearances. 

 

 

 

 

 
DRAFT REQUIREMENTS 
The appliance is merely one component of a larger sys-
tem. The other equally important component is the vent-
ing system. This is necessary for achieving the required 
flow of combustion air to the fire chamber and for safely 
removing unwanted combustion byproducts from the ap-
pliance.  If the venting system's design does not promote 
these ends, the system may not function properly. Poorly 
functioning venting systems may create performance 
problems as well as be a safety hazard (i.e. an oversized 
chimney may result in less than optimum performance. 
Installations into a large, masonry chimney may require a 
liner to improve performance). A draft test should read 
between .05” W.C. (inches water column) and .07" W.C. 

 

American National Standards Institute ANSI/NFPA 211-92, 
draft 1-7: A chimney or vent shall be so designed and con-
structed to develop a flow sufficient to completely remove all 
flue and vent gases to the outside atmosphere. The venting 
system shall satisfy the draft requirements of the connected 
appliance in accordance with the manufacturer’s instructions. 

 
PROVIDE ADEQUATE AIR FOR COMBUSTION  
In well insulated and weather tight homes, it may be diffi-
cult to establish a good draft up your chimney. The poor 
draft is caused by a shortage of air in the house. To pro-
vide the needed air, crack a window on the windward 
side of the house. 
 
VENTILATION REQUIREMENTS 

 
THE FRESH AIR REQUIREMENTS OF THIS APPLI-
ANCE MUST BE MET WITHIN THE SPACE WHERE IT 
WILL BE INSTALLED. 

 

Ventilation is essential when using a solid fuel burning 

heater. The combustion process of this heater uses oxy-

gen from inside the dwelling and it may be necessary to 

open a window or install a vent to provide make-up air 

into a dwelling that is well insulated (modern construction 

standards have resulted in homes that are highly energy-

efficient and that allow little heat loss and air transfer). 

Other appliances in the dwelling also contribute to re-

moving air from the dwelling (i.e. clothes dryers, exhaust 

fans, fireplaces, and other fuel burning appliances). If the 

available fresh air delivery in the dwelling is insufficient to 

support the demands of these appliances, problems can 

result (i.e. excessive negative pressure can develop in 

the dwelling which will affect the rate at which this appli-

ance can draft. See Draft Requirements on this page).
