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 seconds and a safety timing of 5 seconds. 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.

F. Oil Connections

WARNING: This burner is shipped with the oil pump set to operate on a single line system. To operate on a two-linesystem 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 guage 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: The unit cabinet must have an uninter- rupted or unbroken electrical ground to minimize per- sonal injury if an electrical fault should occur. A green ground screw is provided in control box for this connec- tion.

115-V WIRING

Before proceeding with electrical connections, make certain that voltage, frequency, and phase correspond to that specified on unit rating plate. Also, check to be sure that service provided by utility is sufficient to handle load imposed by this equipment. Refer to rating plate or Table 7 for equipment electrical specifications.

Make all electrical connections in accordance with National Electrical Code (NEC) ANSI/NFPA 70-1996 and any local codes or ordinances that might apply. For Canadian installations, all electrical connections must be made in accordance with Canadian Electrical Code CSA C22.1 or subauthorities having jurisdiction.

CAUTION: Do not connect aluminum wire between disconnect switch and furnace. Use only copper wire.

The control system depends on correct polarity of power supply. Connect HOT wire (H) and NEUTRAL wire (N) as shown in Fig. 3 or Fig. 4.

A separate line voltage supply MUST be used with a fused disconnect switch or circuit breaker between main power panel and unit. (See Fig. 3 or Fig. 4.)

Metallic conduit (where required/used) may terminate at side panel of unit. It is not necessary to extend conduit inside unit from side panel to control box.

When replacing any original furnace wiring, use only 105°C No. 14 AWG copper wire.

24-V WIRING

Instructions for wiring thermostat (field supplied) are packed in thermostat box. Make thermostat connections as shown in Fig. 3 or Fig. 4 at 24-v terminal board on fan timer board.

ACCESSORIES

When installing optional accessories to this appliance, follow manufacturer’s Installation Instructions included with accessory. Other than wiring for thermostat, wire with a minimum of type ″ T″ insulation (63°F rise) must be used for accessories.

I. Horizontal or Downflow Installation

For horizontal installation, determine which ″ side″ will become the

″top″ , when the unit is laid down. Remove the flue pipe clearance knock-out from the top of that side panel. Install the flue elbow so that it exits the cabinet of the furnace through that opening.

For counterflow installation, the flue pipe must exit the cabinet through 1 of the side panel openings (as above), then extended up the side of the furnace. Insure that adequate clearances to com- bustibles are observed. Downflow Conversion/Vent Guard Kit MUST be used.
