NOTE
• Condensate drain tubing must
be cut to appropriate length and
slopping towards condensate trap,
ensuring that drain hoses do not
create traps prior to the condensate
trap assembly.
• Condensate trap must be primed
with water prior to initial furnace
start up.
• Any increase of venting must be
done on the vertical sections NOT
horizontal sections.
1. Determine the most suitable vent and drain options for installation. See Figures 22-25 for reference, and
refer to Exhauster Rotation Instructions section if necessary.
2. Remove the 3½” plastic vent cap (if required), and cover vent hole not in use. Install rubber grommet (in
parts bag) for 2” vent pipe. Connect vent pipe (field supplied). If using 1½” or 3” vent, make transition as
close as possible to the unit and on a vertical section.
3. Remove the plastic air inlet cap and connect the 2” pVC air intake connector with the rubber gasket on the
outside of the unit using the 2” lock nut (in parts bag). If using 1½” or 3” air intake pipe, make transition as
close as possible to the unit and on a vertical section.
4. Connect 2” air intake pipe (field supplied).
The exhaust vent must be supported appropriately prior to
it being fitted to the exhauster. Under no circumstances shall the exhauster bear any weight of the
venting system.
5. Remove the two plastic caps attached to the blower division, and the one attached to the side panel if ap-
plicable.
6. Affix the condensate trap assembly to the interior of the side panel in the blower compartment for upflow
positions; (the interior of the side panel in the burner compartment for downflow positions) using the two
screws provided (in parts bag). For horizontal positions affix the condensate trap assembly to the exterior
side panels.
7. make sure combustion department is fully sealed.
NOTE
: It is recommended that pliers be used to firmly clamp the plastic hose clamps.
NOTE
barbed fittings must be fully inserted into
condensate trap, seated to barb flange.
The furnace may condense as much as a 4½ pounds of water per hour (approximately 2 imperial quarts, 2½ u.S.
quarts or 2¼ liters). It is necessary to make provisions for draining the condensate away. The furnace is supplied
with a drain trap assembly. See Figures 22-25 for possible locations of the drain trap.
The drain coupling on the exhauster will work better if the drain holes are pointed down about 15 degrees. The
drain hose supplied with the furnace is long enough to reach either side panel; however, it must be cut to fit each
application. This is to prevent kinking in the drain lines.
Affix the condensate trap assembly to the interior of the side panel in the blower compartment for upflow posi-
tions; the interior of the side panel in the burner compartment for downflow positions. For horizontal positions
affix the condensate trap assembly to the exterior side panels.
Three plastic drain hose clamps are provided in the parts bag. The large one (black) is used for securing the
drain hose to the front manifold cover drain outlet. The medium one (white) is used for securing the drain hose
to the 5/8” barbed fitting on the condensate trap assembly. The small one (black) is used to secure the drain
hose to the ½” barbed fitting on the condensate trap assembly.
