Routing the In-tent Controller and Cable Through the Tent Duct Tunnel.
Ensure that the ON/OFF switch on the in-tent controller assembly is in the OFF position
before connecting the in-tent controller cable to the heater. If the switch is in the ON
position, the heater will start as soon as the cable is connected to the heater.
The in-tent controller with attached cable (1) is routed through the tent duct tunnel (2) nearest the
breathable air inlet end (3) of the heater from outside the tent. The breathable air inlet (3) is the end of the
heater opposite the exhaust (4) and is labeled on the top of the heater.
To route the in-tent controller and cable (1) into the tent, open the end of the tent duct tunnel (2) nearest
the breathable air inlet (3) of the heater and reach into the tent duct tunnel (2) placing the in-tent controller
with attached cable (1) into the interior of the tent. Be sure that the cable is not crimped, tangled, or
positioned in a way that could cause the cable to become damaged during heater operation.
Once the in-tent controller is positioned inside the tent, attach the connector (5) at the opposite end of the
in-tent controller cable to the electrical connector (6) on the heater assembly. Tighten the connector
