ELECTRICAL
The appliance must be installed in accordance with current ANSI/NFPA 70 National Electrical Code, CSA C22.1 Canadian Electrical Code Part 1, and/or local codes.
The control system depends on correct polarity of power supply. Connect HOT wire (H) and NEUTRAL wire (N) as shown in Fig. 7.
→A separate line voltage supply MUST be used with a fused disconnect switch or
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.
Use only copper wire for
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. 16 AWG copper wire.
Instructions for wiring thermostat (field supplied) are packed in thermostat box. Make thermostat connections as shown in Fig. 7 at
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.

FILTERS
WARNING: Never operate unit without a filter or with filter access door removed. Failure to adhere to this warning could lead to a hazardous condition which could lead to equipment damage and bodily harm.
An internal filter is provided as standard equipment with furnace. Refer to Keeping Filters Clean section for filter cleaning informa- tion.
OPERATIONAL CHECKOUT
DO NOT START BURNER UNLESS BLOWER ACCESS DOOR IS SECURED IN PLACE.
Installation of furnace is now complete and operational checkout may be performed.
I.START-UP
1.Check wiring against wiring diagram shown in Fig. 7.
2.Open valve on oil supply line.
3.Reset primary control.
4.Set thermostat above room temperature.
5.Set main electrical switch to ON position. Burner should start.
DO NOT TAMPER WITH UNIT OR CONTROLSÐCALL YOUR SERVICE TECHNICIAN.
II.RECOMMENDED INSTALLATION PRACTICES AND COMBUSTION CHECK
In order to obtain optimum performance from oil burner, the following setup procedures must be followed:
1.A test kit (Bacharach No. 5022 kit or equivalent) to measure
smoke, stack draft,
2.The proper smoke number has been established by engi- neering tests to be between 0 and 1. This degree of smoke emission is commonly referred to as a "Trace" of smoke. It is recommended to use a Bacharach true spot smoke test set or equivalent.
3.In order to ensure proper draft through furnace, a baromet- ric draft regulator (supplied with furnace) must be installed as close to outlet of furnace as possible.
→In order for this device to function properly, barometric damper must be mounted with hinge pins horizontal and face of damper vertical. (See instructions included with damper.) The draft regulator should be adjusted after furnace has been firing for at least 10 minutes, and stack draft should be measured and set between
4.The
There should be a pressure drop of between 0.005 and 0.015 in. wc through furnace. This would set the range of the
5.The CO2 and stack temperature instruments enable you to obtain data required to determine thermal efficiency of furnace.
6.An oil filter should be installed as close to burner as possible with ALL oil burners and is essential on lower firing rate burners. We recommend the use of a low pressure drop oil filter such as the General Filter, Inc. model
7.The oil pressure regulator is factory set to give nozzle oil pressures of 100 psig. The firing rate noted on nameplate may be obtained with "standard" nozzles by adjusting pump pressure as noted in Table 4 or on label on furnace.
On a new installation, air entrapped in oil line leading from tank to nozzle must be thoroughly purged in order to prevent excessive after drip. The oil pump is provided with
aspecial fitting which allows purging of any air between tank and oil pump. The proper procedure for performing this operation is as follows:
a.Place a piece of clear plastic
b.Start oil burner, then open purge fitting and allow burner to run until purge tube is completely free of air bubbles.
