WALL SWITCH INSTALLATION
Since. the. VDVF36TPNEA/TSTEA. series.
uses.a.4.VAC.current.supplied.from.a.trans-
former.mounted.on.the.ignition.module.and.is.
prewired.for.easy.connection.to.a.wall.switch.
(see.Figure.34)..The.(V)DVF36TPNA/TSTA.
models.use.a.self.generated.millivolt.current.
that. allows. you. to. activate. the. gas. control.
valve.directly.without.the.use.of.normal.house-
hold.electricity.(see.Figure.35)..Both.versions.
are.supplied.with.a.wall.switch.kit.for.ready.
connection.and.mounting.
WARNING: Do not wire re-
mote wall switch to main power
supply (Standard 120v house
-
