3. 

Store wood in a cool, dry place well away from any source of flame or heat.  If stored outside, keep the 

 

fuel covered to protect from rain or snow.  If stored inside, fuel should be kept in a covered metal 

 

container at least 6 inches above the floor.  Keep paper, rags and other easily ignited materials away 

 

from wood fuel.  Refer to NFPA 96 for wood storage procedures. 

 
4. 

At least at the end of each shift the area around the unit must be thoroughly cleaned of all wood, wood 

 

shavings, embers, ashes and other refuse.  All mats (if present, mats must be non-combustible) must be 

 

picked up and carefully swept along with the floor during this clean up.  After clean up around the unit,  

 

brooms should be thoroughly wet down to extinguish hot coals, then stored well away from combustible 

 materials. 
 
5. 

Creosote - Formation and need for removal 

 
 

When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled 

 

moisture to form creosote.  The creosote vapors condense in the relatively cool oven flue and exhaust 

 

hood of duct, particularly a slow burning fire.  As a result, creosote residue accumulates on the flue lining 

 

and exhaust hood.  When ignited, this creosote makes an extremely hot fire. 

 
 

The oven flue, exhaust duct and power ventilator should be inspected at least twice monthly during 

 

normal use to determine if creosote buildup has occurred.  If creosote and/or grease has accumulated, it 

 

should be removed to reduce the risk of fire.  Experienced chimney and duct servicing personnel who 

 

are qualified in the removal of both creosote and grease from flues and ducts should be contracted to do 

 

the inspection and cleaning.  The inspection and cleaning schedule must be adjusted as needed to 

 

prevent the buildup of creosote and/or grease. More frequent inspections and cleanings are indicated 

 

when excessive buildup occurs between regular inspections.  The rate of accumulation can increase 

 

whenever 1) there is a change in the use of the oven 2) when the type or moisture content of the 

 

firewood changes 3) when other variables change. 

 
 

The oven, exhaust hood and grease filters should be cleaned on a daily basis.  The Grease filters can be 

 

removed and cleaned in a dishwasher or sink.  Refer to the NFPA 96 requirements and the Exhaust 

 

Hood or Grease Duct manufacturer's instructions for inspection, maintenance and cleaning of the venting 

 system. 
 

DO NOT CLEAN UNIT, HOOD OR VENT WHILE HOT OR WHILE OVEN IS BEING FIRED. 

 

6. 

The entire unit and vent system should be inspected frequently for proper fit, operation and soundness of 

 

parts.  If any malfunctioning parts, leakage, deterioration, or other problems are noted, contact your 

 

dealer to inspect and repair the unit, or qualified ventilation repair service to inspect and repair the vent 

 

system.  DO NOT OPERATE THE UNIT IF  INSTALLED OR FUNCTIONING IMPROPERLY. 

 
7. 

All maintenance must be performed by qualified personnel. 

 
8. 

Refer to NFPA 96 for procedures for inspection, cleaning and maintenance for solid fuel cooking. 

 
9. 

SERVICE OF OVEN TEMP. MONITORING EQUIPMENT 

 

A)
