All models can be installed on combustible floors
and in alcoves. Minimum clearance from
combustible construction is 0 inches on all sides.
A minimum 3 inch clearance on top, both sides
and in the rear and a minimum 24 inch
clearance in front and on top should be available
for adequate inspection and servicing.
The water heater should not be located in an
area where leakage from the tank or water
connections will result in damage to the
adjacent area or to lower floors of the
structure. When such areas cannot be
avoided, a suitable drain pan or non-
flammable catch pan, adequately drained,
must be installed under the water heater.
The pan must be connected to a drain.
NOTE: Auxiliary catch pan MUST conform to
local codes.
Catch pan or drain pan kits made of metal are
available in 16”, 19”, 22”, 24” and 26-1/2”
diameters from the distributor or store where the
water heater was purchased.
RESTAURANTS
If the water heater is to be installed in a
restaurant or other location where the floor is
frequently cleaned, it must be elevated to
provide at least 6 inches of clearance from the
floor to comply with NSF International
recommendations. A factory-designed leg
extension kit is available for this purpose from
the distributor or store where the water heater
was purchased.
CORROSIVE ATMOSPHERES
The heater should not be located near an air
supply containing halogenated hydrocarbons or
high humidity. For example, The air in beauty
salons, dry cleaning establishments, photo
processing labs and storage areas for liquid and
powder bleaches or swimming pool chemicals
often contains such hydrocarbons.
The limited warranty is voided when failure of
the water heater is due to a corrosive
atmosphere. TURBOMAX
®
water heaters
designed for corrosive atmospheres are
available from the distributor or store where the
water heater was purchased.
