Combustion & Ventilation Air; Installing Your Wall Furnace - COZY C255H Manual Del Propietário

After picking a location that meets the requirements, check
the walls, attic and roof to make sure there are no obstructions
such as pipes, electrical wiring, etc., which could interfere with the
installation of the furnace or vent pipe. If required, move them or pick
a new location.
WARNING: Danger of property damage, bodily injury or
loss of life. Do not install the furnace in any area where
oxygen is in use.
COMBUSTION & VENTILATION AIR
When an existing category I heater is removed or replaced, the
original venting system may no longer be sized to properly vent
the attached appliances.
WARNING:
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each appliance
connected to the venting system being placed into operation
could result in carbon monoxide poisoning or death.
The following steps shall be followed for each appliance connected
to the venting system being placed into operation, while all other
appliances connected to the venting system are not in operation:
1. Seal any unused openings in the venting system.
2. Inspect the venting system for proper size and horizontal pitch,
as required in the National Fuel Gas Code, ANSI Z223.1/NFPA
54 or the natural gas and propane Installation Code, CSA
8149.1 and these instructions. Determine that there is no
blockage or restriction, leakage, corrosion and other
deficiencies which could cause an unsafe condition.
3. As far as practical, close all building doors and windows
and all doors between the space in which the appliance(s)
connected to the venting system are located and other
spaces of the building.
4. Close fireplace dampers.
5. Turn on clothes dryers and any appliance not connected to the
venting system. Turn on any exhaust fans, such as range hoods
and bathroom exhausts, so they are operating at maximum
speed. Do not operate a summer exhaust fan.
6. Follow the lighting instructions. Place the appliance being
inspected into operation. Adjust the thermostat so appliance is
operating continuously.
7. Test for spillage from draft hood equipped appliances at the draft
hood relief opening after 5 minutes of main burner operation.
Use the flame of a match or candle.
8. If improper venting is observed during any of the above tests,
the venting system must be corrected in accordance with the
National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or natural
gas and propane Installation Code, CSA 8149.1
9. After it has been determined that each appliance connected to
the venting system properly vents when tested as outlined
above, return doors, windows, exhaust fans, fireplace dampers
and any other gashed burning appliance to their previous
conditions of use.

INSTALLING YOUR FURNACE
The high cost of energy for home heating has brought about new
materials and methods used to construct or remodel most current
homes. The improved construction and additional insulation has
reduced the heat loss and made these homes much tighter around
windows and doors so that infiltrated air is minimal. This creates a
problem to supply combustion and ventilation air for gas-fired or other
fuel burning appliances. Any use of appliances that pull air out of the
house (clothes dryers, exhaust fans, fireplaces, etc.) increases this
problem and appliances could be starving for air.
The combination of a tight energy efficient home with the use of exhaust
fans, fireplaces, clothes dryers, and gas appliances result in more and
more air being drawn from the house until fresh air may be sucked
back into the house down a furnace flue or fireplace chimney. Carbon
monoxide can be the result. Carbon monoxide (CO) is a colorless,
odorless gas produced when fuel is not burned completely or when the
flame does not receive sufficient oxygen. Automobiles, charcoal, wood
fires and improperly vented or air-starved coal, oil and gas furnaces or
other appliances can produce carbon monoxide.
Do not install furnace in the same room or near a wood solid fuel
burning fireplace.
BE AWARE OF THESE AIR-STARVATION SIGNALS:
1. Headaches, nausea, dizziness.
2. Excessive humidity shown by heavily frosted windows or
a moist clammy sensation.
3. Fireplace smoke fills the room or will not draw.
4. Furnace flue backs up.
AIR REQUIREMENTS
The requirements for providing air for combustion and ventilation
are listed in the National Fuel Gas Code NFPA 54/ANSI Z223.1 (in
Canada: CAN/CGA B149). Most homes will require that outside air
be supplied to the heated area by means of ventilation grilles or ducts
connecting directly to the outside or spaces open to the outdoors
such as attic or crawl space. The only exception is when the heated
area meets the requirements and definitions for an unconfined space
with adequate air infiltration.
All air openings and connecting ducts must comply with
the following:
If the furnace is installed in an area with another gas appliance(s),
the total input rating of all appliances must be considered when
determining the free area requirements
for combustion and ventilation air openings.
Ducts must have the same cross-sectional area as the free area
of the openings to which they connect. The minimum dimension of
rectangular air ducts must not be less than 3-inches in length
or height.
WARNING: Danger of property damage, bodily injury
or loss of life. The furnace and any other fuel-burning
appliances must be provided with enough fresh air for
proper combustion and ventilation of flue gases. Most
homes will require that outside air be supplied into the
heated area.
