2.2 Corrosive Chemicals

Bananza cannot be responsible for ens

u

ring that all 

appropriate safety meas

u

res are 

u

ndertaken prior to 

installation; this is entirely the responsibility of the 
installer. It is essential that the contractor, the s

u

b-

contractor, or the o

w

ner identifies the presence of 

comb

u

stible materials, corrosive chemicals or 

halogenated hydrocarbons* any

w

here in the 

premises.

* Halogena

t

e

d

 Hy

d

rocarbons

 are a family of chemical 

compounds characterized by the presence of halogen 
elements (fluorine, chlorine, bromine, etc.). These com-
pounds are frequently used in refrigerants, cleaning 
agents, solvents, etc. If these compounds enter the air 
supply of the burner, the life span of the heater compo-
nents 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 heater is exposed to halogenated hydrocarbons.

2.3 National Standards and Applicable Codes

All appliances m

u

st be installed in accordance 

w

ith 

the latest revision of the applicable standards and 
national codes. This refers also to the electric, gas 
and venting installation. Note: Additional standards 
for installations in p

u

blic garages, aircraft hangars, 

etc. may be applicable.

CAUTION

Product Damage Hazard

Do not use heater in area containing 
corrosive chemicals.

Refer to appropriate Material Safety Data 
Sheets (MSDS).

Failure to follow these instructions can result 
in product damage.
