accumulation creates a fire hazard, 
making its reduction or removal 
imperative.

One method of reducing creosote 
buildup is to gradually stoke a  
medium hot fire for 15-30 minutes  
at least once per day. This tends 
to burn off the creosote in small 
amounts. Seasoned or dry woods  
tend to form less creosote deposits 
than unseasoned or wet wood. In 
mild weather, frequent, slow burning 
of the fireplace will severely aggravate 
the creosote problem.

Frequent inspection of chimney flues 
is important, especially during the 
first season of use. Any problems with 
creosote buildup can be corrected 
before it becomes a hazard. Inspect 
the chimney regularly from the roof 
using a flashlight, or alternatively by 
using a mirror to look up through the 
flue. If an inspection indicates soot or 
creosote buildup, the chimney should 
be cleaned. 

CAUTION: The use of chemicals 
which are supposedly meant to  
clean the chimney when they are 
placed on the fire could produce heat 
intense enough to cause damage to 
the concrete masonry and clay flue 
liners, contributing to the deteriora-
tion of these elements.    

MASONRY BAKE OVEN

Wood-fired ovens constructed of  
masonry materials have been used  
for cooking and baking for centuries. 
In the past two decades we have  
seen a significant increase in the  
construction of masonry ovens  
designed for commercial and  
residential applications, for both 
inside and outside use.  

The architectural sketch that follows 
offers some design suggestions. Many 
additional designs are feasible, with 
varying materials in different shapes 
and sizes. Some are built traditionally 
using masonry materials from scratch. 

Others use pre-engineered component 
parts offering the latest technology, 
providing operational efficiency and 
ease of construction.  

No matter your preference in oven 
design, all products used in masonry 

 

CODE ENFORCEMENT  

oven construction (e.g., brick, block, 
firebrick, refractory components,  
stucco, stone, terra cotta, etc.) are 
widely available at your local masonry 
supply dealer. As with all masonry 
construction, carefully observe fire 
safety and code compliance. 

NOTIFICATION

Code enforcement authorities must be notified when solid- burning fuel 

heating appliances or chimney construction materials are purchased  

or acquired. 

All businesses selling or installing solid fuel burning heating appliances  

and / or chimney construction materials must notify the purchaser(s) in  

writing at the time of sale or acquisition that they are legally required to 

notify their local code enforcement official before installation commences. 

Please accept this Tek Spec 4.0 document as official written notification  

of the above.
