COMPACT-MULTI – INSTALLATION/OPERATION MANUAL
1.0 HOMEOWNER INFORMATION
1.1 INTRODUCTION
Please read and understand this manual before installing, operating or maintaining the
furnace. To ensure you have a clear understanding of the operating procedures of the
appliance please take the time to read section 1.0 HOMEOWNER INFORMATION of this
manual.
1.2 AIR FILTERS
To maintain furnace performance and safety, replace dirty filters as required or at least once
every heating season. Use new approved disposable filters of the same size and type, or
clean permanent filters according to manufacturer’s instructions. Replace the filters or clean
the filters more often if dusty conditions exist. Dirty, clogged or wrong sized filters will impair
the furnace performance and may cause the furnace to shut down or overheat. The filter
bracket can be moved from the left side to the right side or the bottom of the furnace. See
Figure - 7.
1.3 REGULAR MAINTENANCE
Check complete operation at least once a year. In Canada see B139, Section 14,
Maintenance, for recommended servicing procedure. Heat exchanger ducts are accessed
through breech access panels at front of unit. Replace stainless steel gas baffles after
cleaning. Cerafelt (1/4”) gaskets may have to be replaced.
1.4 WARNINGS
NEVER burn garbage or paper in the unit.
NEVER store combustible material around it.
DO NOT attempt to start burner when excess oil has accumulated, when unit is full of vapour
or when heat exchanger is very hot.
DO NOT use gasoline, crankcase drainings or any oil containing gasoline.
1.5 DIRECT VENT
It is the responsibility of the homeowner to ensure that the area around the Direct Vent
terminal and air intake is free of snow, ice and debris. The vent terminal should be checked
during heavy snowstorms to ensure proper operation.
1.6 SHUTTING FURNACE DOWN
POWER OFF Turn off main power switch.
FUEL OFF Shut off manual fuel supply valve.
Always keep manual fuel supply valve shut off if the burner is shut down for an extended
period of time.

1.7 RESTARTING FURNACE
Follow this procedure before restarting a unit that has been shut down for an extended period
of time.
INSPECTION Have the furnace/system serviced and inspected by a qualified technician.
Ensure furnace/system has not been tampered with.
FUEL Turn on fuel supply and check that there are no leaks.
POWER Turn on power and check that the furnace starts and operates as usual.
OPERATION If the furnace/system fails to operate or operates in an unusual manner, call
your service technician. If the burner fails to operate at any time, call a
qualified burner technician.
2.0 INSTALLATION
2.1 IMPORTANT
Read the instructions thoroughly before installing furnace or starting burner. Consult local
authorities about your local Fire Safety Regulations. All installations must be in accordance
with local state or provincial codes. Improper installation will result in voiding of warranty.
2.2 CAUTION
DO NOT START THE BURNER UNTIL ALL FITTINGS, COVERS AND DOORS ARE IN
PLACE. DO NOT TAMPER WITH THE FURNACE OR CONTROLS, CALL A QUALIFIED
BURNER TECHNICIAN. FOR YOUR SAFETY: DO NOT STORE OR USE GASOLINE OR
OTHER FLAMMABLE VAPOURS AND LIQUIDS IN THE VICINITY OF THIS OR ANY OTHER
APPLIANCE.
2.3 INSTALLATION CODES
Installation MUST comply with the requirements of authorities having jurisdiction. All local an d
national codes governing the installation of oil burning equipment, wiring and venting must be
followed. Some of the applicable codes are:
CAN/CSA B139 Installation Code for Oil Burning Equipment.
NFPA 31 Installation Code for Oil Burning Equipment.
ANSI/NFPA 90B Warm Air Heating and Air Conditioning Systems.
ANSI/NFPA 70 National Electrical Code.
CSA C22.1 Canadian Electrical Code.
ANSI/NFPA 211 Chimneys, Fireplaces, Vents and Solid Fuel Burning Appliances.
The latest versions of the above codes, which have been approved for use in the location of
the installation, must be used.

COMPACT-MULTI – INSTALLATION/OPERATION MANUAL
2.4 MULTI - POSITION
The Compact-multi is designed to operate in either upflow, downflow or horizontal mode. The
breech is convertible from front to rear by switching the breech pipe and cover plates. The
burner is always installed in an upright position by four nuts.
2.5 PLACEMENT & VENTING
Furnace installation should conform to the required installation code for oil-fired equipment
(USA: NFPA 31, Canada: CSA B139).
UPFLOW Install the furnace close to chimney or vent and central to ductwork. The
furnace may be placed on a combustible floor or, if required, on a Granby
Appliance Stand or four (4) rigid blocks. The floor must be strong enough
to carry the weight of the furnace. The furnace is shipped in upflow
configuration.
DOWNFLOW Install the plenum and sub-base as shown in Figure - 5 or the illustration
included with sub-base kit (K4C-KA-0500-00). A sub-base is required to
support the furnace. This sub-base maintains the clearances to
combustible materials through the floor and provides a convenient
attachment to the plenum. For furnaces installed on a combustible floor,
ensure that the requirements of the authorities having jurisdiction are
satisfied.
HORIZONTAL In suspended horizontal positions four 3/8”-16 x 4” eyebolts and 3/8” nuts
are use to suspend the furnace. Determine the appropriate side and
remove the knockouts. Four weld nuts (3/8 - 16 UNC) are concealed
behind knockouts on either side of the furnace. For installations where the
furnace will be supported from below, use 4” long 3/8” UNC bolts as
adjustable legs. Eyebolts complete with locking nuts are available. The
locking nuts should be threaded on the eyebolt 3/4” to 1”. This provides a
stop for the eyebolt.
CHIMNEY/VENT Connect the furnace to a chimney/vent system of size and condition
required by the NFPA 31 (USA) or CSA B139 (Canada) code. Furnace is
approved for factory built chimney type “L” vent. Breech is certified for 5”
vent pipe. Keep vent/flue pipe as short as possible with min. 1/4” per foot
upward slope. Use approved fitting through a wall. Vent/flue pipes MUST
NOT pass through a ceiling. Maximum flue gas temperature is 575°F.
THROUGH-THE- Furnace is approved for Granby Direct Vent with Riello burner.
WALL VENTING
COMBUSTION & Install openings and ductwork to the furnace room to provide fresh outside
VENTILATION AIR combustion and circulation air for cooling the furnace casing, as
installation codes require (USA: NFPA 31, Canada: B139). If installed in
a closed room, provide two free air ventilation openings of at least 8” x 12”
(96 sq. in.) free flow area near ceiling and floor. Oil burners must have
sufficient air to allow vent systems to operate properly. See furnace
operating label. Not applicable to Direct Vent.

COMPACT-MULTI – INSTALLATION/OPERATION MANUAL
BREECH The breech is convertible from front to rear by switching the breech pipe
with the cover plate and cabinet cover panels.
DRAFT Use approved draft control supplied for 5” pipe. Use two draft controls on
strong draft chimneys. Set specified draft pressure to -0.03” wc. Not
applicable to Direct Vent installations.
AIR FILTER The filter bracket can be moved from the left side to the right side or the
bottom of the furnace. See Figure - 7.
ELECTRICAL Wire according to the National Electrical Code (Canadian Electrical Code
in Canada) or local codes. Use a separately fused #12 electrical line
directly from the service panel to the furnace junction box. Install a
manual shut off switch at the door or stairway to furnace room so furnace
can be shut off remotely.
COMBINATION The Compact-multi can be used with the Scotty SS providing the 0.60 US
gph nozzle is used. This will ensure that adequate air circulates through
the Scotty SS. Set blower speed to high. If the Compact-multi is used in
a down flow position with the Scotty SS, a diverter base is available for
easier duct connections.
SUB-BASE The sub-base kit is used to provide the proper support and clearances for
a furnace that is used in the downflow position and is mounted on a floor
with the supply ducting running beneath the floor (K4C-KA-0500-00).
DIVERTER BASE The diverter base is used to provide proper support when the Compact-
multi furnace is used in the downflow position and the supply ducting is
above the floor, or for the add-on to a wood furnace. This base is a
furnace supporting 90 degree elbow (K4C-KA-0400-00).
SPACE HEATER The space heater kit is used when the furnace is heating the only room in
which it is located. The kit consists of two louvered blower side panels
and a louvered air diffuser top, which mounts on the top of the furnace in
place of ductwork (K4C-KA-0100-00).
VESTIBULE The vestibule is used to cover the burner and provide a burner
compartment. It is sometimes used in conjunction with the space heater
kit (K4C-KA-0600-00).
ADD-ON Any furnace can only have one additional appliance added to the
ductwork. Other items which do not drastically reduce the air flow are
allowed.
