INSTALLATION INSTRUCTIONS
Important Notice
These instructions are intended
for
qualified personnel,
specificallytrained and experienced in
the
installation
of
thistype
of
equipment and related system components.
Some states or provinces require installation and service
personnel
to
be
licensed.
If
your state
or
province
is
such,
be
sure yourcontractor bears the appropriate
license. Persons not qualified shall not attempt
to
fix this
equipment
nor
attempt repairs.
.A WARNING
Asphyxia, Explosion
or
Fire
Improper installation, adjustment,
alteration, service
or
maintenance
may
create a hazard resulting
in
asphyxiation,
explosion
or
fire, or damage
to
the
equipment.
Code Requirements
Installation
must
be
in
accordancewith local codes, or in
the
absence
of
local codes, with
the
latest edition
of
the
National Fuel Gas Code, ANSI Z224 and National
Electrical Code ANSI/NFPA 70, and
for
Canada, the
latest edition
of
CAN/CGA-B149.1 and B149.2 and
Canadian Electrical Code,
CSA
C22.1 Part 1 and Part 2.
• Heaters
to
be
installed
in
Aircraft hangars must
be
installed
in
accordancewith American National
Standards
for
Aircraft Hangars, ANSI/NFPA
No. 409.
• Heaters
to
be
installed
in
Public Garages must be
installed
in
accordancewith NFPA No. 88A,
Standards
for
Parking Structures.
• Heaters must be installed
so
that minimum
clearances marked
on
the
heaterswill
be
maintained from vehicles parked below
the
heater.
• Each heatermust
be
electrically grounded
in
accordancewith
the
National Electrical Code,
ANSI/NFPA 70, when an external electrical source
is
utilized. In Canada,
the
CSA Canadian Electrical
Code, C22.1 Part 1 applies.

Gas Supply
The
gas inlet supply pressure and manifold pressure required
for
each heater are listed below. For gas supply line pressures in
excess
of½
psi, consult with your gas service provider
or
the
factory.

It
is
critical
that
the
gas piping system
be
adequately sized
for
all
the
gas
appliances it serves.
Clearances
Each heater
must
be
installed such that the following
"Minimum Clearance
to
Combustible Materials' are maintained.
Combustible materials include wood, compressed paper, plant
fibers, plastic, Plexiglas or other materials capable
of
being
ignited and burned. Such materials shall
be
considered
combustible even though flame-proofed, fire retardant treated or
plastered. Additional clearance may
be
required
for
glass,
painted surfaces, vinyl siding
or
other materials which may
be
damaged
by
radiant
or
convection heat.
Adequate space around each heater is required even when the
materials surrounding the heater are non- combustible
to
provide
adequate combustion
air
and ventilation
of
exhaust gases.
Heaters should never
be
located in a ceiling recess
or
ceiling
enclosure.
The stated clearance
to
combustible materials represents a
surface temperature
of
90°F (32°C) above room temperature.
Building materialswith a
low
heat tolerance (such
as
plastic, vinyl
siding, canvas, tri-ply, etc.)
may
be subject
to
degradation
at
lowertemperatures. It is the installer's responsibility
to
assure
that adjacent materials are not subject
to
degradation.
In
locations used for storage
of
combustible materials, signs
shall be posted
to
specify
the
maximum permissible stacking
height
to
maintain required clearances from
the
heaterto
combustible materials.
OPTIONAL MOUNTING KIT (#12006): Optional Mounting Kit
is
included
in
some
packages.
Whether
the mounting kit is used or
not, minimum clearance from combustibles
must
be
observed
as
follows:
WARNING:
The
clearances shown below are also applicable
to
vehicles parked below heaters.
