H. PREVENT COMBUSTION AIR CONTAMINATION
Install intake piping for the appliance as described in the Venting section. Do not terminate exhaust in locations that can allow
contamination of intake air.
Ensure that the intake air will not contain any of the contaminants below. For example, do not pipe intake near a swimming pool. Avoid
areas subject to exhaust fumes from laundry facilities. These areas always contain contaminants. Contaminated air will damage the
appliance, resulting in possible substantial property damage, severe personal injury, or death.
AREAS LIKELY TO HAVE CONTAMINANTS
Spray cans containing fluorocarbons
Dry cleaning/laundry areas and establishments
Chlorinated waxes/cleaners
Chlorine-based swimming pool chemicals
Calcium chloride used for thawing
Refrigeration repair shops
Sodium chloride used for water softening
Paint or varnish removers
Plastic manufacturing plants
Hydrochloric or Muriatic acid
Furniture refinishing areas and establishments
New building construction
Antistatic fabric softeners used in clothes dryers
Chlorine-type bleaches, laundry detergents, and cleaning solvents
Adhesives used to fasten building products
NOTE: DAMAGE TO THE APPLIANCE CAUSED BY EXPOSURE TO CORROSIVE VAPORS IS NOT COVERED BY WARRANTY.
(Refer to the limited warranty for complete terms and conditions).
I. REMOVING AN APPLIANCE FROM A COMMON VENT SYSTEM
Do not install the appliance into a common vent with any other appliance. This will cause flue gas spillage or appliance malfunction,
resulting in possible substantial property damage, severe personal injury, or death.
Failure to follow all instructions can result in flue gas spillage and carbon
monoxide emissions, causing severe personal injury or death.
When removing an existing appliance, the following steps must be
followed.
1. Seal any unused openings in the common venting system.
2. Visually inspect the venting system for proper size and horizontal pitch
to determine if there is blockage, leakage, corrosion or other deficiencies
that could cause an unsafe condition.
3. If practical, close all building doors, windows and all doors between the
common venting system and other spaces in the building. Turn on clothes
dryers and any appliances not connected to the common venting system.
Turn on any exhaust fans, such as range hoods and bathroom exhausts,
at maximum speed. Do not operate a summer exhaust fan. Close all
fireplace dampers.
4. Place in operation the appliance being inspected. Follow the lighting
instructions. Adjust the thermostat so the appliance will operate
continuously.
5. Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle or
smoke from a cigarette.
