Empire Heating Systems ULTRASAVER 90 PLUS PVS18N-3 Guide D'utilisation Et Instructions D'installation page 28

To prevent flue pipe from pushing back into the wall, place a hose
clamp on the pipe against the wall and tighten. See Figure 41.
For direct-vent installations, the inlet air pipe will only extend
1/4" through the wall into the rear shroud. The inlet pipe will butt
against the stopping flange provided with the air pipe kit. See
Figure 42.
Due to the high efficiency of the Ultra Saver, condensate will form
in the heat exchanger and flue pipe. A condensate trap and drain
tube are provided to dispose of the condensate to a nearby floor
drain. An optional humidification tray is also available to evapo-
rate the condensate back into the room as humidity instead of
draining it away from the wall furnace. See page 15.
If draining the condensate away from the wall furnace, route the
condensate drain tube provided in the instruction envelope to the
elbow on the tube sticking through the back of the wall furnace
to a nearby drain. See Figure 43. The elbow may be rotated to
direct the hose to either side or straight down. Eliminate all sags
or dips as they may prevent drainage. An optional drain tube
extension kit and optional condensate pump kit accessory are
available. See page 15.
Notice: Due to the mildly acidic nature of wall furnace condensa-
tion, check with local authorities to determine if a ph neutralizing
process may be required.

VENTING
Attach the transition box to the back of the wall furnace with six
10 x 1/2" hex-head screws. See Figure 44.
Carefully push the wall furnace back into position against the rear
shroud and connect the flue pipe to the inducer.
Attach the wall furnace to the rear shroud by using four 10 x 1/2"
(13mm) hex-head screws previously removed (see page 21). See
Figure 45. Do not tighten the screws.
Reinstall the filter door by inserting the filter door tabs into the
two receiving slots on top of the rear shroud. Close the filter door,
then adjust the wall furnace positions to minimize the gap be-
tween the wall furnace casing and the filter door. Tighten the four
wall shroud screws to secure the wall furnace in place.
Notice: For floor mounted wall furnaces, ensure the adjustable
legs are all on the floor.
To complete inside installation open the filter door and, tighten
the inducer hose clamp with a 10-inch 5/16" nut driver. See
Figure 46.
