in the manual together with the cited codes and
regulations to perform the installation.

Section 608 of the US Environmental Protection
Agency (EPA) Clean Air Act of 1990 or equivalent
certification program.

3.1 Corrosive Chemicals
Addison cannot be responsible for ensuring that all
appropriate safety measures are undertaken prior to
installation; this is entirely the responsibility of the installer.
It is essential that the contractor, the subcontractor, or the
owner identifies the presence of combustible materials,
corrosive chemicals or halogenated hydrocarbons*
anywhere in the premises.
* Halogenated Hydrocarbons
are a family of chemical compounds
characterized by the presence of halogen elements (fluorine,
chlorine, bromine, etc.). These compounds are frequently used in
refrigerants, cleaning agents, solvents, etc. If these compounds
enter the air supply of the burner, the life span of the unit
components will be greatly reduced. An outside air supply must
be provided to the burners whenever the presence of these
compounds is suspected. Warranty will be invalid if the unit is
exposed to halogenated hydrocarbons.
WARNING
EXPLOSION HAZARD
Equipment must have access to
uncontaminated air at all times.
Failure to follow these instructions
can result in death, injury, or
property damage.
CAUTION
PRODUCT DAMAGE HAZARD
