Boiler Manual
Prepare boiler location — contamination
Table 1 Corrosive contaminants
1d
If the boiler is installed in any area likely to cause contamination, or if products which
would contaminate the air cannot be removed, you must pipe combustion air to the boiler
air intake. Contaminated combustion air will damage the boiler, resulting in possible severe
personal injury, death or substantial property damage. Do not install CGs boiler in a
laundry
room or pool facility, for example, without using ducted outside air. These areas will always
contain contaminants.
