11.0 ROUTING OPTIONS
H16.0.4B
This furnace can be installed in either up
fl
ow or horizontal right position, see “EXHAUSTER ROTATION
INSTRUCTIONS & PRESSURE SWITCH MOUNTING” section for installation positions with correct exhauster
orientation, condensate drainage, and pressure switch locations. The installer must also
consider the following services: gas pipe, electrical power, drain trap, intake and exhaust
vents, the air conditioning connections and drain, access to
fi
lter(s) and access to furnace
and a/c for repair. Drains and traps of furnaces installed in spaces subjected to freezing
temperature must also be protected against freezing.
The combustion air inlet
fi
tting is a 2” PVC Socket to Flange adapter. Install the adapter to
the outside of the exterior panel using the screws provided (ensure gasket is properly placed
between the adapter and the outside of the exterior panel for proper sealing).
Failure to apply gasket on
cabinet exterior voids the warranty.
11.1 CONDENSATE DRAINS
H16.2.5
The furnace may condense as much as 4-1/2 pounds of water per hour (approximately 2 imperial quarts, 2-1/2
U.S. quarts or 2-1/4 liters). It is necessary to make provisions for draining the condensate away. The furnace is
supplied with a drain trap assembly. See Figures 16-20 for possible locations of the drain trap.
Af
fi
x the condensate trap assembly to the exterior of the side panel of the blower compartment for up
fl
ow
positions. For horizontal positions af
fi
x the condensate trap assembly to the exterior side panels. See Figures
16-20.
Four plastic drain hose clamps are provided in the parts bag. The large ones are used for securing the drain
hose to the front manifold cover drain outlet, and securing the drain hose to the 5/8” barbed
fi
tting on the
condensate trap assembly. The small one is used to secure the drain hose to the exhauster drain collar and
the 1/2” barbed
fi
tting on the condensate trap assembly.
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
fi
t each
application. This is to prevent kinking in the drain lines.
NOTE
: It is recommended that pliers be used to
fi
rmly clamp the plastic hose clamps.
NOTE
: The hoses comes connected to the inducer and FMC from manufacturer. Installer must connect
hoses to barbed
fi
ttings on condensate trap.
NOTE
: The pressure switch pack and exhauster cannot be moved on upfl ow and horizontal right
installations.
1. Determine the most suitable vent and drain options for installation, see “EXHAUSTER ROTATION
INSTRUCTIONS & PRESSURE SWITCH MOUNTING” section.
2. Install rubber grommet (in parts bag) for 2” vent pipe. Connect vent pipe (field supplied). If using 1-1/2” or
3” vent, make transition as close as possible to the unit and on a vertical section.
3. 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.
4. 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).
5. Ensure rubber grommets are located on appropriate side panel for trap location and sealing caps are
located to ensure upper vestibule is sealed.
6. Affix the condensate trap assembly to the exterior of the side panel for upflow 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 compartment is fully sealed.
