10 - 120 Volt Wiring -
Millivolt Units - 120 volt wiring is required on Millivolt
units only when a fan kit is being installed. Wire fan
kit according to figure 37.
Electronic Ignition 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
properly installed. Glass must not be broken or
cracked. If glass is damaged, replace with ap-
propriate glass/frame assembly available through
Lennox repair parts. Substitution of any other than
Lennox-specified glass can lead to property dam-
age or personal injury.
13 - Carefully reinstall the glass door. Tighten the three
bolts at the bottom of the door securely.
14 - Install the bustle; in flush-faced model applica-
tions, install the top panel; in louvered-face model
applications, install the louvers.
15 - Remove the eyebrow from its protective wrap-
ping. Slide the eyebrow into the slots on the lower
edges of the radiant panel (flush-faced model ap-
plications) or the lower edges of the cabinet top
(louvered-face model applications).
NOTE - The eyebrow must be used in all applications.
