For any chimney or vent, this should include the following:
1. Inspection for any deterioration in chimney or vent. If
deterioration is discovered, chimney must be repaired or
vent must be replaced.
2. Inspection to ascertain that vent system is clear and free of
obstructions. Any blockage must be cleared before install-
ing furnace.
3. Cleaning chimney or vent if previously used for venting a
solid fuel burning appliance or fireplace.
4. Confirming that all unused chimney or vent connections are
properly sealed.
5. Verification that chimney is properly lined and sized per the
applicable codes. (Refer to list of codes in Safety Consid-
erations section.)
MASONRY CHIMNEYS
This furnace can be vented into an existing masonry chimney. This
furnace must not be vented into a chimney servicing a solid fuel
burning appliance. Before venting furnace into a chimney, the
chimney MUST be checked for deterioration and repaired if
necessary. The chimney must be properly lined and sized per local
or national codes.
If furnace is vented into a common chimney, the chimney must be
of sufficient area to accommodate the total flue products of all
appliances vented into chimney.
The following requirements are provided for a safe venting
system:
1. Be sure that chimney flue is clear of any dirt or debris.
2. Be sure that chimney is not servicing an open fireplace.
3. Never reduce pipe size below the outlet size of furnace.
(See Fig. 2.)
4. All pipe should be supported using proper clamps and/or
straps. These supports should be at least every 4 ft.
5. All horizontal runs of pipe should have at least 1/4 in. per
ft of upward slope.
6. All runs of pipe should be as short as possible with as few
turns as possible.
7. Seams should be tightly joined and checked for leaks.
8. The flue pipe must not extend into chimney but be flush
with inside wall.
9. The chimney must extend 3 ft above highest point where it
passes through the roof of a building and at least 2 ft higher
than any portion of a building within a horizontal distance
of 10 ft. It shall also be extended at least 5 ft above highest
connected equipment flue collar.
10. Check local codes for any variance.
FACTORY-BUILT CHIMNEYS
Listed factory-built chimneys may be used. Refer to chimney
manufacturer’s instructions for proper installation.
E.
Oil Burner
This furnace is supplied with a high-pressure atomizing retention
head-type burner (for use with grade 1 or 2 fuel oil). The Riello oil
burner operates with a prepurge period of 10 sec and a safety
timing of 5 sec. The burner flange is factory installed for an
inspection length of 3-3/4–in. The oil pump is set to operate on a
single line system. To operate on a two-line system the by-pass
plug must be installed.

CAUTION:
UNIT DAMAGE HAZARD
Failure to follow this caution may result in unit compo-
nent damage.
This burner is shipped with the oil pump set to operate on
a single line system. To operate on a two-line system the
by-pass plug must be installed. Do not operate a single
line system with the by-pass plug installed. Operating a
single line system with the by-pass plug installed will
result in damage to the pump shaft seal.
Pump pressure must be set at time of burner start-up. A
pressure gauge is attached to the PRESSURE PORT for
pressure readings. Two PIPE CONNECTORS are sup-
plied with the burner for connection to either a single or
two-line system. Also supplied are two ADAPTORS,
two female 1/4–in. NPT, to adapt oil lines to burner pipe
connectors. All pump ports are British Parallel Thread
design. Direct connection of NPT threads to the pump
will damage the pump body.
Riello manometers and vacuum gauges do not require
any adapters and can be safely connected to the pump
ports. An NPT (metric) adapter must be used when
connecting other gauge models.
Complete instructions for installing fuel oil piping can be found in
oil burner Installation Instructions included with furnace.
Oil line entry holes are provided in side panels. Two holes are
provided in each location so that a 2-pipe system may be used if
desired.
An oil filter should be used with all oil burners and should be
installed as close to burner as possible.
G.
Barometric Draft Control
The barometric draft control shipped with furnace MUST be used
with furnace to ensure proper operation. Instructions for installing
control are packed with control.
H.
Electrical Connections
WARNING:
ELECTRICAL SHOCK AND FIRE
HAZARD
Failure to follow this warning could result in serious
injury, death, or property damage.
The unit cabinet must have an uninterrupted or unbroken
electrical ground to minimize personal injury if an
electrical fault should occur. A green ground screw is
provided in control box for this connection.
