appliance and the blower.
II. Removing the junction box cover on the
appliance exposes 4 black, labeled wires:

thermally activated switch enabling the user to
run the blower without heat).
• 1 wire labelled "blower": connects to KB-35
rheostat (not supplied) and then fan-speed
control blower wire connects to white blower
wire.
• 1 wire labelled "L1": connects to power (hot
lead).

blower exposes 3 coloured wires:

note:
We recommend installing the blower in a different room or
even different level of the house. This will generate great
air movement and improve the distribution of the warm air
coming from the appliance.
important:
Marrett by-pass (summer) switch wire leads sepa-
rately (do not connect together) if the by-pass switch
is not desired.
