The Electronic Intermittent Ignition Device automatically
lights the pilot and main burners upon a call-for-heat. The
heater is supplied with a dual-voltage transformer for 120
VAC or 240 VAC input power hookup.
When operating on 120 VAC power, units draw 4 amps.
When operating on 240 VAC power, units draw 2 amps.

Heater must be electrically grounded and bonded in
accordance with local codes, or, in the absence of local
codes, with the latest edition of the National Electrical
Code, ANSI/NFPA 70. (Canada - Canadian Electrical
Code, CSA C22.1, Part 1 and Part 2.)
A CAUTION: If the transformer's primary side is wired
for 120 VAC and 240 VAC is applied, damage to the
transformer and PC board may result. Such damages
are not covered under manufacturer's limited warranty.
Input power to the heater (120 or 240 VAC) can
NOTE:
be supplied from the load (pump) side of time clock or
directly from the GFCI power source. It is preferred
that full-time power be supplied to the heater from
the GFCI power source, and that the heater be
controlled by the fireman's switch connection or
using a two or three-wire remote. If using a switched
GFCI power source, the heater could display false
service indicators on the display panel if the pump is
turned off.
