RECEIVING AND WAREHOUSING

Inspect the unit upon arrival for any s hipping damage. If any part is missing or damaged, mark the
bill of lading as to damage and notify the carrier and factory at once.

If the unit cannot be installed immediately, store the unit in a clean and dry place.

GENERAL HANDLING INSTRUCTIONS

A qualified and experienced crane operator must do all rigging. General rigging methods should be
followed in all cases:

a) Spreader bars must be used when lifting equipment.
b) Equipment must be lifted simultaneously by all “eye” bolts or channel slots provided on

each section at the same time to distribute the loading properly. Damage or injury may
result if all provisions for lifting are not utilized at time of lift. When multiple lifting eyes
are furnished they are to share the weight of the lift evenly via spreader bar(s).

c) Lifting eyes and channel slots are designed to be lifted vertically. The MAXIMUM angle

from a vertical lift, which is permitted, is 30 degrees. Single sections only are to be lifted at
one time and stacked from the lowest section upward. Sections are designed to be self­supporting in compression only. Do not attempt to hang multiple sections from any
structure. The total perimeter base and all frame structure must be supported, and levelled,
on high-density concrete or sufficient I-beam steel.

d) For some models the heating and blower sections may be shipped separately. Assemble the

sections by aligning the base frames and/or the pre-drilled flanges and secure the assembly
with the fasteners provided. Use gasketing material to prevent infiltration at the joints.

WARNING

FAILURE TO COMPLY WITH THE GENERAL REQUIREMENTS MAY RESULT IN

EXTENSIVE PROPERTY DAMAGE, SEVERE PERSONAL INJURY OR DEATH.

GENERAL INSTALLATION NOTES

a) In Canada the installation must conform with local building codes or, in the absence of

local building codes, with the current CAN/CGA -BI49.1 or B149.2 “Installation Codes
for Gas Burning Appliances and Equipment”. Indoor duct furnaces have been designed
for, and certified to comply with, CAN/CGA2.8.

b) Installation must be made in accordance with local codes or in absence of local codes

with ANSI Standard Z223.1-1992 (N.F.P.A. No.54) “National Fuel Gas Code” or the
latest edition of all ANSI and NFPA standards. Standards referred to in these installation
instructions are in effect at the time of certification. ANSI Standards are available from
the American Gas Association 1515 Wilson Boulevard, Arlington, Virginia 22209. NFPA
standards are available from the National Fire Protection Association, Battery March Par,
Quincy, Massachusetts 02269. Heaters referred to in this manual are designed for use in
airplane hangers when installed in accordance with ANSI/NFPA No.409 and in public
garages when installed in accordance with the NFPA No. 88a and NFPA No.88b.

c) No alterations are to be made on this equipment.
d) For suspended appliances that are installed in aircraft hangers, parking structures, and

repair garages must be installed in accordance with the standard on aircraft hangers,
ANSI/NFPA 409, the standard for parking structures. ANSI/NFPA 88a, the standard for
repair garages, ANSI/NFPA 88b, and with the CAN I-B149 codes,

CLEARANCE TO COMBUSTIBLE MATERIALS in inches (mm)

TOP FRONT BACK FLOOR SIDES ACCESS SIDE

6(152) 6(152) 6(152) 3(76) 6(152) 18(457)

All units installed on the floor have a minimum clearance of 3" (76mm) provided by the base frame
of each individual unit.

For service it is advisable to maintain a minimum 24' clearance on the side opposite the controls
side. If this unit is to be operated within a confined space or within a building of unusually tight
construction, air for combustion and ventilation must be obtained from outdoors or other spaces
freely communicating with the outdoors. Refer to current United States and Canadian Fuel Codes.

Ducts connected to the fur nace shall have removable access panels on both the upstream and
downstream sides of the furnace. These openings shall be accessible when the furnace is installed
and shall be sized to allow for the observation of smoke or reflected light inside the casing to
indicate the presence of leaks in the heat exchanger. The covers for the openings shall be attached
in such manner as to prevent leaks.

WARNINGS

Ø The furnace must not be operated in the presence of hazardous atmospheres

containing flammable vapours or combustible dust, chlorinated vapours or
halogenated hydrocarbons, or in applications with airborne substances
containing silicone. When such vapours mix with products of combustion,
highly corrosive compounds result, which will result in the premature failure
of the heat exchanger and other components. In such an event the warranty is
void.

Ø The duct furnace is not certified or suitable for use in drying process

applications. Use in such application voids any warranty and as the
manufacturer disclaims any responsibility for the duct furnace and/or
application.

Ø The use and storage of gasoline or other flammable liquids in the vicinity of

the appliance is hazardous.

CONNECTING THE FLUE (VENTING)

OUTDOORS INSTALLATIONS

AIR FOR COMBUSTION

Openings for combustion air must be provided in a panel (door) with direct access to the
vestibule area where the burners and draft inducer are located. This air opening must be of
sufficient size to provide a suitable supply of air for combustion to the burner compa rtment,
but not less than one (1) square inch free area per every 8000 Btu per hour of the specified
maximum input rate. The minimum dimension of any air opening should not be less than 3
inches. Heating appliance must be installed so that air access to inlet opening is
unobstructed.

VENTING

The vent termination must be located in accordance with the National Fuel Codes (ANSI
Z223.1) in the US or CAN/CGA-B149 Installation code in Canada.
The venting system for outdoor units is a Category 111, with vent products at positive

pressure and up to 500 °F. The cross-section area of the vent duct or pipe must be at least
equal to the discharge area of the draft inducer.

The discharge opening must always be located in the same pressure zone as the combustion
air inlet.

o For horizontal discharge, the outlet should be located on the same side of the

unit as the combustion air inlet. Never locate the vent outlet on the opposite
side from the combustion air inlet opening.

o For Horizontal discharge where the flue gases need to be vented vertically,

the preferred flue gas discharge should terminate in an exterior flue riser that
extends at least to the top of the cabinet and is open at the top and bottom.
This riser must be located on the same side of the appliance as the
combustion air opening.

INDOOR INSTALLATIONS

AIR FOR COMBUSTION

The furnace must be installed in a location with adequate clearances to provide for an
adequate combustion air space, service and inspection, and proper clearance for
combustible construction. The furnace shall be located in such a manor that it does not
interfere with the circulation of air in the heated space.

All fuel burning equipment must be supplied with air that enters into the combustion
process and is then vented outdoors. Sufficient air must enter the appliance location to
replace the air exhausted through the vent system. Do not install appliances in a confined
space without providing wall opening to and from this space, if building construction is
such that the normal infiltration does not provide sufficient air for combustion and venting,
outside air must be introduced in accordance with ANSI Z223.1 (Sect. 1.3.4.2 and 1.3.4.3).
Install air openings that provide that provides a total free area in accordance with the
following:
