Installation
Instructions (cont'd)
All electric wiring and connections, including electrical grounding MUST be
in accordance with the National Electric Code ANSI/NFPA No. 70 (latest edi-
tion) or, in Canada, with the Canadian Electrical Code, Part I-C.S.A., Standard
C22.1. In addition, the installation must comply with local ordinances and appli-
cable gas company requirements.
The electrical supply wiring connects to your heater on the upper rear of the left
side of the unit (facing the back of the heater). Locate the two black hole plugs
in the wiring connection holes. Carefully pinch and remove these two plugs; do
not pry. (See FIGURE 7; location of holes will be either to the side or below the
access panel.)
1) Attach the Wire Conduit - Screw one of the conduit connectors to one
end of each piece of flexible conduit (See FIGURE 8). Insert the end of the
conduit with the connector into one of the holes from which you removed the
black plugs ( FIGURE 7). Push until the connector snaps into place. Repeat
with the other assembled conduit and connector.

2) Position the Wires and the Box Connectors (See FIGURES 9 and 10.)
- Using a 1/4" socket or a screwdriver, remove the cover from the power
venter junction box. Depending on the direction of the vent, position the
straight box connector and the 90° box connector at the knockouts in the
junction box. Be sure that the straight connector is positioned so that it will
be possible to tighten the holding screw. Attach the box connectors using
their locknuts. Tighten with pliers.

Route the conduit pieces to the connectors. (The conduit in the hole clos-
est to the rear of the heater will attach to the 90° connector; the conduit in
the hole toward the front of the heater will attach to the straight connector.)
Depending on the size of the unit and the direction of the vent, you may have
to shorten the lengths of the conduit pieces. The conduit must not interfere
with fan operation or contact the hot surfaces of the flue gas collection box
or vent pipe. To shorten, bend the conduit until it breaks. Using a pair of wire
snips, finish cutting and deburr the end.
Line Voltage Wires (black and white) and the Conduit in the Hole Closest to the Rear of the Heater - Feed
the two line voltage wires (black and white) through the piece of conduit attached to the hole closest to the
rear of the heater. Insert a red plastic anti-short bushing in the end of the conduit.
Low Voltage Wires (brown, yellow, blue, and orange) and the Conduit in the Hole Closest to the Front of
the Heater -- Feed the four low voltage (brown, yellow, blue, and orange) wires through the piece of conduit
