AFTER LIGHTING THE FIRE, leave the combustion air regulator open in the position shown:
TERMOROSA DSA 4.0
IMPORTANT:
• do not add further wood between one complete load and the next;
• do not suffocate the fire by closing the air intakes;
• regular cleaning by a chimney sweep reduces fine particle emissions.

NORMAL OPERATION
IMPORTANT: FOR SAFETY REASONS THE DOOR OF THE HEARTH CAN BE OPENED ONLY FOR THE LOADING OF THE
FUEL. THE HEARTH DOOR MUST ALWAYS REMAIN CLOSED DURING OPERATION OR REST.
After having positioned the registers correctly, insert the indicated hourly wood load avoiding overloads that cause anomalous stresses
and deformations. YOU SHOULD ALWAYS USE THE PRODUCT WITH THE DOOR CLOSED IN ORDER TO AVOID DAMAGES DUE TO
OVERHEATING (FORGE EFFECT). THE INOBSERVANCE OF THIS RULE MAKES THE WARRANTY EXPIRE.
For safety reasons the door of the appliances with constructive system 1, must be opened only for the loading of the fuel or for removing the
ashes, while during the operation and the rest, the door of the hearth must remain closed.
The appliances with constructive system 2 must be connected to their own flue. The operating with open door is allowed under supervision.
With the controls positioned on the front of the appliance it is possible to adjust the heat emission of the hearth. They have to be opened
according to the calorific need. The best combustion (with minimum emissions) is reached when, by loading the wood, most part of the air for
combustion flows through the secondary air register.
NEVER OVERLOAD THE APPLIANCE (SEE THE HOURLY WOOD LOAD IN THE TABLE HERE BELOW). TOO MUCH FUEL AND TOO MUCH AIR
FOR THE COMBUSTION MAY CAUSE OVERHEATING AND THEN DAMAGE THE APPLIANCE. YOU SHOULD ALWAYS USE THE APPLIANCE
WITH THE DOOR CLOSED IN ORDER TO AVOID DAMAGES DUE TO OVERHEATING (FORGE EFFECT). THE INOBSERVANCE OF THIS RULE
MAKES THE WARRANTY EXPIRE.
The adjustment of the registers necessary to reach the rated calorific yield with a depression at the stack of 12 Pa (1,2 mm of column of water)
is the following one: see chapter TECHNICAL DESCRIPTION. The appliance works as an intermittent operating appliance.
IN THE EVENT THAT THE WATER TEMPERATURE EXCEEDS THE TRIPPING TEMPERATURE OF THE SAFETY DEVICES,
IMMEDIATELY SUSPEND THE FEEDING OF WOOD, AND MAKE SURE THAT THE WATER TEMPERATURE AND THE FLAME
DECREASE, ELIMINATING THE CAUSES OF THE OVERHEATING (IF NECESSARY BY CLOSING THE AIR REGISTER).
IF THE WATER SYSTEM IS CONNECTED IN THE APPLIANCE, THE HOT WATER TAP CAN BE OPENED TO SPEED UP THE COOLING
OF THE APPLIANCE.
BESIDES THE ADJUSTMENT OF THE AIR FOR THE COMBUSTION, THE INTENSITY OF THE COMBUSTION AND CONSEQUENTLY THE THERMAL
PERFORMANCE OF THE DEVICE IS INFLUENCED BY THE STACK. A GOOD DRAUGHT OF THE STACK REQUIRES A STRICTER ADJUSTMENT OF
AIR FOR COMBUSTION, WHILE A POOR DRAUGHT REQUIRES A MORE PRECISE ADJUSTMENT OF AIR FOR COMBUSTION.
To verify the good combustion, check whether the smoke coming out from the stack is transparent.
If it is white, it means that the device is not properly adjusted or the wood is too wet; if instead the smoke is gray or black, it signals that the
combustion is not complete (it is necessary a greater quantity of secondary air).
WARNING: WHEN FUEL IS ADDED ONTO THE EMBERS IN THE ABSENCE OF A FLAME, A CONSIDERABLE AMOUNT OF FUMES
MAY DEVELOP. SHOULD THIS HAPPEN, AN EXPLOSIVE MIXTURE OF GAS AND AIR MAY FORM, AND IN EXTREME CASES
AN EXPLOSION MAY OCCUR. FOR SAFETY REASONS IT IS ADVISABLE TO PERFORM A NEW LIGHTING PROCEDURE
WITH THE USE OF SMALL STRIPS.
USE OF THE FOOD WARMER (IF PRESENT)
Place the smoke controller in the position USE OF THE Food warmer (see chap. TECHNICAL DESCRIPTION)
Thanks to the air flow for the combustion, the temperature of the Food warmer may become remarkably affected. A sufficient flue of the
chimney and of the channels, well cleaned for the flow of burning smokes around the Food warmer are fundamental for a good cooking result.
The Food warmer pan may be located on different plans. Thick cakes and big roasts must be introduced in the lowest level. Flat cakes and
biscuits must reach the medium level. The upper level may be used to heat or grill.
The Food warmer pan and the chrome plated Food warmer grille may be located on different plans (see chapter Technical Description -
ACCESSORIES).
WHEN YOU HEAT VERY HUMID FOODS, CAKES WITH FRUIT OR FRUIT ITSELF, WATER OF CONDENSATION WILL BE PRODUCED. DURING
THE COOKING PROCESS SOME WATER VAPOUR IN THE FORM OF DROPS OF CONDENSED WATER CAN DEPOSIT ONTO THE TOP AND THE
SIDE OF THE DOOR. IT IS A PHYSICAL PHENOMENON.
By opening the door briefly and carefully (1 or 2 times, or even often in case of longer cooking times) you can let out the steam from the
cooking compartment and reduce condensation significantly.
