All units require particular clearances for proper operation<br />
<strong>and</strong> service. Installer must make provisions for adequate<br />
combustion <strong>and</strong> ventilation air in accordance with section 5.3<br />
of Air for Combustion <strong>and</strong> Ventilation of the National Fuel <strong>Gas</strong><br />
Code, ANSI Z223.1 – Latest Edition (in U.S.A.), or Sections<br />
7.2, 7.3, or 7.4 of <strong>Gas</strong> Installation Codes, CSA-B149.1 (in<br />
Canada) - Latest Edition, <strong>and</strong>/or applicable provisions of the<br />
local building codes. Refer to Table 7 for clearances required<br />
for combustible construction, servicing, <strong>and</strong> proper unit operation.<br />
Do not permit overhanging structures or shrubs to<br />
obstruct condenser air discharge outlet, combustion<br />
air inlet or vent outlets.<br />
Excessive exposure to contaminated combustion air<br />
will result in safety <strong>and</strong> performance related problems.<br />
To maintain combustion air quality, the recommended<br />
source of combustion air is the outdoor air<br />
supply. The outdoor air supplied for combustion<br />
should be free from contaminants due to chemical<br />
exposure that may be present from the following<br />
sources.<br />
• Commercial buildings<br />
• Indoor pools<br />
• Laundry rooms<br />
• Hobby or craft rooms<br />
• Chemical storage areas<br />
The following substances should be avoided to<br />
maintain outdoor combustion air quality.<br />
• Permanent wave solutions<br />
• Chlorinated waxes <strong>and</strong> cleaners<br />
• Chlorine based swimming pool cleaners<br />
• Water softening chemicals<br />
• De-icing salts or chemicals<br />
• Carbon tetrachloride<br />
• Halogen type refrigerants<br />
• Cleaning solvents (such as perchloroethylene)<br />
• Printing inks, paint removers, varnishes, etc.<br />
• Hydrochloric acid<br />
• Cements <strong>and</strong> glues<br />
• Anti-static fabric softeners for clothes dryers<br />
• Masonry acid washing materials<br />
