Millivolt Units - 120 volt wiring isrequired on Millivolt
units only when a fan kit is being installed. Wire fan
kitaccordingtofigure37.
ElectronicIgnition Units All electronic ignition units
require 120 volt wiring. Install wiring according to fig-
ure 38.
When 120 volt electrical power is applied, the ap-
pliance must be electrically grounded according to
local codes or, in the absence of local codes, with the
current National Electric Code, ANSI/NFPA No. 70,
in the USA or CSA C22.1 Canadian Electrical Code
in Canada.
11 - Prepare the vent collar for use as indicated in the
venting section. Attach either Lennox flexible or unit-
ized rigid concentric vent to vent collar, at the top
(DT/DTH units) or rear (DR/DRH units), of the ap-
pliance as indicated in the venting section. Vent ter-
minations are indicated in venting section.
12 - Make gas piping connections as indicated in gas pip-
ing section.
WARNING
Do not operate appliance unless glass frame is
