Check Building Codes

When installing, operating and maintaining your stove, follow the guidelines presented in these in-

structions, and make them available to anyone using or servicing the stove.
Your city, town, county or province may require a building permit to install a solid fuel burning appli-

ance.

In the U.S., the National Fire Protection Association’s Code, NFPA 211, Standards for Chimneys, 

Fireplaces, Vents and Solid Fuel Burning Appliances, or similar regulations, may apply to the in-

stallation of a solid fuel burning appliance in your area.  In Canada, the guideline is established by 

the CSA Standard, CAN/CSA-B365-M93, Installation Code for Solid-Fuel-Burning Appliances and 

Equipment.

Before installing your stove

Adequate Provision of Air

Always consult your local building inspector or authority having jurisdiction to determine what regu-

lations apply in your area.

You need to consider the following to ensure the safe operation of your stove. 
• Provision of adequate air to support efficient combustion of the fuel. 
• A well sealed flue/chimney system, herein after referred to as the “flue system”.  
• The protection of combustible materials in proximity of the stove. 

It is essential for the safe and efficient use of your stove that you provide an adequate air supply to 

your stove. This may mean the provision of an outside air supply to the room, especially if there are 

extraction units such as cooker hoods or clothes dryers in the vicinity. Failure to do so will mean that 

fuel is burned inefficiently causing smoke and blackening the glass and may also cause smoke to 

come back into the room. As a simple check for this open a door or window in the room and check 

if the stove burns more efficiently.
