Installation & Operation Manual

3 General venting

If the boiler combustion air inlet is

located in a laundry room or pool

facility, for example, these areas will

always contain hazardous

contaminants.

To prevent the potential of severe

personal injury or death, check for

areas and products listed in Table 1A,

page 11 before installing the boiler or

air inlet piping.

If contaminants are found, you

MUST:

• Remove products permanently.

—OR—

• Relocate air inlet and vent

terminations to other areas.

 WARNING

Air contamination

Pool and laundry products and common household and hobby

products often contain fluorine or chlorine compounds. When

these chemicals pass through the boiler, they can form strong

acids. The acid can eat through the boiler wall, causing serious

damage and presenting a possible threat of flue gas spillage or

boiler water leakage into the building.

Please read the information given in Table 1A, page 11, listing

contaminants and areas likely to contain them. If

contaminating chemicals will be present near the location of

the boiler combustion air inlet, have your installer pipe the

boiler combustion air and vent to another location, per this

manual.
