Installation must be in accordance with local

codes, or, in the absence of local codes, with the  latest
editions of the  National Fuel Gas Code, ANSI Z223.1,
and the National Electrical  Code, ANSI/NFPA 70.  In
Canada, installations must conform with the current
CAN/CGA B149.1 or .2 and the Canadian Electrical
Code Part 1 CSA C22.2 No.1.  Where required by the
authority having jurisdiction, the installation must con-
form to American Society of Mechanical Engineers
Safety Code for Controls and Safety Devices for Auto-
matically Fired Boilers, No. CSD-1.

Boiler should be mounted on a level surface.  Each

boiler is designed with a built-in sub-base approved for
mounting the boiler on combustible flooring.  Boiler
must NOT be installed on carpet flooring.

NOTE: The boiler should be located in an area where
water leakage will not result in damage to the area
adjacent to the appliance or to the structure.  When
such locations cannot be avoided, it is recommended
that a suitable drain pan, adequately drained, be in-
stalled under the appliance.  The pan must not restrict
air flow.

In addition, the boiler shall be installed such that

the gas ignition system components are protected from
water (dripping, spraying, rain, etc.) during appliance
operation and service (circulator replacement, control
replacement, etc.)

2) A front clearance of at least 24" is recommended for

adequate service of burner-tray and controls.

3) Except for carpeted   flooring, boilers are certified  for

installation on combustible floors.

4) For un-insulated hot water pipes, maintain a 2"

clearance, or consult local authority having jurisdic-
tion.

 WARNING: Air supply to the boiler room must not be
affected by mechanical exhaust vents located in other
parts of the house, such as kitchen or bathroom fans,
or  attic blowers.  Mechanical exhaust vents may create
a negative pressure condition in the boiler room that
can become a hazard of asphyxiation, explosion or fire.

 CAUTION: Combustion air must not be contaminated
by corrosive chemical fumes which can damage the
boiler.  Measures must be taken to prevent the entry of
corrosive chemical fumes to the combustion and ven-
tilation air supply.  Such chemicals include, but are not
limited to, chlorinated and/or fluorinated hydrocarbons
such as found in refrigerants, aerosol propellants, dry-
cleaning fluids, degreasers, and paint removers.  Other
harmful elements may come from bleaches, air fresh-
eners, or mastics.  Vapors from these types of products
can form corrosive acid compounds when burned in a
gas flame.  The resulting acid condensate can damage
or substantially reduce the life of the heater.  It may be
necessary to provide outside air directly to the heater in
order to avoid this problem.

1) The boiler must be provided with adequate supply of

air for proper combustion and ventilation in accor-
dance with Sec. 5.3, of the  latest edition of the
National Fuel Gas Code, ANSI Z223.1, or appli-
cable provisions of the local building codes.
