Gas utilization equipment requiring controlled draft may be equipped with a listed double
acting barometric draft regulator, if approved by local codes (see Figure 4).
A device which will automatically shut off gas to the burner in the event of sustained
backdraft is required. It shall be of the listed manual reset type and installed and adjusted by
a qualified service technician in accordance with the manufacturer’s instructions.
Refer to gas utilization equipment manufacturer for recommended vent connection
requirements.
____________________________________________
CAUTION:Refer to wiring diagram located on the inside of the burner housing
cover or above wiring diagram. Before proceeding verify burner model number for
correct wiring diagram.
Installation wiring and grounding to the burner must conform to local codes, or, in their
absence in the
United States
to
National Electric Code, ANSI/NFPA No. 70
latest edition;
in
Canada, to Canadian Electrical Code Part 1, CSA Standard C22.1
Use copper wire not less than 14 gage for line voltage wiring. Hook up to a dedicated line
with an on-off disconnect switch and a minimum 10 Amp breaker.
The frame of the burner should be well grounded. Normally the piping and/or electric
conduit will provide sufficient grounding. However, a ground lug is located in control box for
positive grounding where insulated pipe couplings are used or where any doubt exists
regarding grounding sufficiency.
Confirm that the polarity is correct—hot wire to strip terminal L1, neutral L2—and that the
neutral line is not subject to induced low voltage (check L2 to earth ground) from other
equipment, as that can cause the Ignition Control Module to malfunction.
Each installation must include suitable limit control(s). Existing oil burner combination
operating and limit controls are normally NOT SUITABLE for gas burner use.
Connect motors used on forced air furnace fans or boiler pumps to a combination limit
control and switch.
Set the thermostat heat anticipator for the total current draw handled by the thermostat.
The current draw of the ECONOMITE 24V operating circuit is 0.9 amps.
CAUTION: Label all wires prior to disconnection when servicing controls.
Wiring errors can cause improper and dangerous operation. Verify proper operation
after servicing.
