INSTALLATION

Code Requirements

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,/NFPA
54, and the National Electrical Code, ANSI/NFPA 70.
In Canada installations must conform with the current
CAN/CSA B149 and the Canadian Electrical Code
Part 1 CSA C22.2 No.1.
Where required by the authority having jurisdiction, the
installation must conform to American Society of
Mechanical Engineers Safety Code for Controls and
Safety Devices for Automatically Fired Heaters, CSD-
1.

Mounting Base

This heater should be mounted on a level, non-com-
bustible surface. Heater must not be installed on
carpeting. This heater can be installed on a com-
bustible surface only when the appropriate listed floor
shield base is provided. An optional listed floor shield
base is available for factory installation with the heater
on all indoor models.
NOTE: The heater 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 installed under the appliance. The pan
must not restrict air flow.
In addition, the heater 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.).

*Except for carpeted flooring, heaters are certified for installation on
combustible floors, when equipped with listed floor shield base.
**A front clearance of at least 24 in. is recommended for adequate
service of burner-tray and controls.
Table C: Minimum Clearances from Combustible
Combustion & Ventilation Air
(Indoor models only)
WARNING: Air supply to the heater 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 heater room that can become a hazard of
asphyxiation, explosion or fire.
CAUTION: Combustion
contaminated by corrosive chemical fumes which
can damage the heater. Measures must be taken to
prevent the entry of corrosive chemical fumes to the
combustion and ventilation 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 fresheners,
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.
