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.

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.

BURNER SETTING After 5 minutes of normal operation, check smoke for zero to trace
reading and measure CO2. Readjust the burner controls as required.
EFFICIENCY Always leave burner set with CO2reading about 1% of CO2lower than
the peak efficiency achieved with a zero to trace smoke (e.g. a zero to
trace reading of 12.5% CO2should be set back 1% to 11.5%). This
gives better allowance for fuel and draft variations and maintains a
better seasonal efficiency. When the burner is set, lock the
adjustments with the locking nuts.
DO NOT START BURNER UNTIL ALL FITTINGS AND COVERS ARE IN PLACE.
2.9 BLOWER SETTING
Ensure power is off when adjusting blower setting. For heating, use the blower speeds
shown on the furnace specifications to give a rise of 70 - 85°F. The #4 Lo blower speed can
be used for air circulation when neither heating nor cooling are required. Set blower speeds to
match the installation requirements. On the model number the last 2 digits represent the type
of motor: 03 for a PSC 1/3HP motor and E3 for a 1/2HP ECM high efficiency motor.
2.10 AIR CONDITIONING
An air conditioning coil may be installed on the supply side only. Coils installed on the return
side will cause condensation on the heat exchanger that will shorten the heat exchanger life
and may cause products of combustion to enter the house. The bottom of the drain pan must
be at least 10” above the top of the heat exchanger. Wire according to Figure – 4. Height of
the coil above the heat exchanger shall be no less than 10” (254 mm).
*See A/C coil Manufactures Requirements *
2.11 HUMIDIFIER
If a humidifier is installed ensure that no water can drip or run from it into the furnace. This
would cause deterioration and void the furnace warranty.

4.0 BLOCKED VENT SWITCH
Oil-fired appliances installed in Canada require a blocked vent shut-off system when installed
on a chimney. A safety switch is included with the furnace to perform this function. It is the
installer’s responsibility to install the switch in accordance with the instructions provided. Not
applicable for Direct Vent systems.
Field Controls Model: WMO-1 (Manual Reset)
Switch Operation
Blocked vent switches are flue gas safety devices for detecting spillage of flue gases due to a
blocked flue or inadequate draft. After detecting a problem, the switch de-energizes the
system’s burner control.
NEVER reset the switch unless the cause of the blockage has been corrected.

COMPACT-MULTI – INSTALLATION/OPERATION MANUAL
5IM-OF-K4C0-01 Jun/12
10
Installation
1) Pierce a 5/8” hole in to the flue vent pipe near the appliance breech connection.
2) This hole must be at least 10” before the draft regulator, vertically or horizontally.
3) Remove one of the securing nuts from the threaded tube of the safety switch.
4) Tighten the other securing nut onto the pipe as far as possible.
5) Insert the threaded tube end into the pierced hole of the flue vent pipe.
6) Install the securing nut on the safety switch tube, which protrudes into the flue vent pipe.
Tighten the nut securely.
Wiring Instructions
Caution: Disconnect the electrical power when wiring the unit.
Wire the blocked vent switch in accordance with The National Electrical Code and applicable
local codes. Wire the safety switch in series with the burner limit control or aquastat. Route
the wiring with an accepted wiring enclosure in accordance with the National Electrical code
and applicable local codes. Refer to wiring decal or Figure – 4.
System Test Procedure
1) With the power re-established, block the chimney or vent pipe downstream of the switch.
2) Adjust the thermostat to call for heat.
3) Once the heating system has started the blocked vent switch should shut down the
burner within 10 minutes or sooner.
4) Once the system has cooled, the blocked vent switch can manually be reset.
5) This procedure should be tested a second time.
6) After testing the blocked vent switch the chimney should be cleared of obstruction and the
heating system tested on a long run cycle.
If the block vent switch shuts down the system, check to ensure there is enough draft in the
chimney and venting pipes.
5.0 OIL TANK & PIPING
Tank installation must conform to local requirements.
Install according to the applicable code. Minimize number of connections in suction line and
make all connections as tight as possible. Use a pipe joint compound suitable for oil on all
pipe threads. To reduce possibility of air leaks, tighten stem packing gland nut on any valves
installed in the suction line. Also, be sure the oil filter is tight, as filter gaskets often shrink.
Check for kinks in the oil lines as well as for possible air pockets and for loose connections.
Two filters as shown in Figure - 3 are recommended. Optional tank gauge protectors and
outlet protectors are available at your local dealer.
ONE PIPE SYSTEM Where the tank is above the burner and when the oil flows by
gravity to the oil pump, a single-stage fuel unit with a single oil line
to the pump may be used.
TWO PIPE SYSTEM When single line is unsuitable, use double line or see your dealer
for special oil line fittings.
