Ventilation And Aeration Of The Installation Premises - Nordica ROSA XXL UL-C Installation And Operating Instructions Manual

3.3 VENTILATION AND AERATION OF THE INSTALLATION PREMISES

AS THE PRODUCT MIGHT DRAW COMBUSTION AIR FROM THE PLACE OF INSTALLATION, IT IS MANDATORY THAT IN THE PLACE ITSELF, A
SUFFICIENT QUANTITY OF AIR IS INTRODUCED. IF THE HOUSE IS EQUIPPED WITH A WELL-SEALED VAPOR BARRIER AND TIGHT-FITTING
WINDOWS AND/OR HAS ANY POWERED DEVICES THAT EXHAUST HOUSE AIR IT IS POSSIBLE THAT THE FRESH AIR INTAKE IS NO LONGER
GUARANTEED AND THIS JEOPARDISES THE DRAUGHT OF THE APPLIANCE AND YOUR HEALTH AND SAFETY.
Provision for outside combustion air may be necessary to ensure that the product do not discharge products of combustion into
the house. Guidelines to determine the need for additional combustion air may not be adequate for every situation. If in doubt, it is
advisable to provide additional air.
Outside combustion air may be required if:
1. The solid-fuel-fired appliance does not draw steadily, smoke rollout occurs, fuel burns poorly, or back-drafts occur whether or not
there is combustion present.
2. Existing fuel-fired equipment in the house, such as fireplaces or other heating appliances, smell, do not operate properly, suffer
smoke roll-out when opened, or back-draft whether or not there is combustion present.
3. Opening a window slightly on a calm (windless) day alleviates any of the above symptoms.
4. The house is equipped with a well-sealed vapor barrier and tight fitting windows and/or has any powered devices that exhaust
house air.
5. There is excessive condensation on windows in the winter.
6. A ventilation system is installed in the house.
If these or other indications suggest that infiltration air is inadequate, additional combustion air should be provided from the outdoors.
Outside combustion air can be provided to the appliance by the following means:
1. Indirect method: the outside air is ducted to a point no closer than (12 in.) 300 mm from the appliance, to avoid affecting the
performance of the appliance.
2. A mechanical ventilation system: if the house has a ventilation system (air change or heat recovery):
- The ventilation system may be able to provide sufficient combustion make-up air for the solid-fuel-fired appliance.
- The householder should be informed that the ventilation system might need to be re-balanced by a ventilation technician after
installation of the appliance.
IMPORTANT: For a better comfort and corresponding oxygenation of the place of installation, the combustion air can be withdrawn from the
outside of the building through a pipe (not furnished) that which shall have a minimum according the OPTIONAL RING Air Fitting described
in Chapt. ACCESSORIES. This pipe must have a maximum length of 118-in (3 m) and no more than 3 bends.
The air inlets must meet the following requirements:
• they must be protected with grids, metal mesh, etc., but without reducing the net useful section;
• maintenance of the inlet shall be easy and feasible;
• positioned so that they cannot be obstructed;
ALL NATIONAL, AND LOCAL STANDARDS IN FORCE IN THE COUNTRY WHERE THE APPLIANCE IS INSTALLED MUST BE
