Thermo Pride CLHS1-050P36N Installation And Operation Manual page 23

All installations and services must be performed by qualified service personnel.
c. If the Vent is going thru the Left side panel, remove the Door Latch Channel and its 4 screws. Then
remove the Inducer Blower and the 4 nuts & washers which attach it. The Inducer Blower should then
be rotated 180° and re-installed. Do not over-tighten the 4 nuts which attach the inducer, as that may
cause the inducer's internal blower wheel to rub. Replace the 5/16" ID tubing which ran from the
inducer to the pressure switch with the longer piece of tubing provided in the parts kit. Now re-install
the Door Latch Channel and its mounting screws. The flexible drain adapter that was factory installed
on the exit of the inducer must be retained at the exit of the inducer. Now a section of 2-inch PVC pipe
can be installed through the rubber grommet in the left panel into the flexible drain adapter. Tighten the
worm clamp on the flexible drain adapter to seal and hold the PVC pipe in place.
d. If the Vent is going thru the Right side panel, merely install a section of 2-inch PVC pipe through the
rubber grommet in the right panel into the flexible drain adapter. Tighten the worm clamp on the
flexible drain adapter to seal and hold the PVC pipe in place.
3. Connecting The Combustion Air Intake Piping
: Outside combustion air must NOT be drawn from an area directly adjacent to a pool, hot
tub or spa. Measures should be taken to prevent the entry of corrosive chemicals or vapors into the
combustion air supply. Such chemicals include but are not limited to chlorinated and/or fluorinated
hydrocarbons such as found in refrigerants, aerosol propellants, dry cleaning fluids, degreasers ,
bleaches, air fresheners or solvents. Vapors from such products can form reactive acid producing
chemical species when burned in a gas flame. Should acidic compounds form in the furnace they may
significantly reduce the useful life of the furnace.
a. The Combustion Air Intake piping may enter the furnace thru either the top, left or right side as
depicted in Figure 7. Upon selection of the location to exit the furnace, cut out the appropriate knock-
out and install the Intake Air Flange provided using 4 self-tapping screws.
b. A section of 2-inch PVC pipe should then be inserted into the Intake Air Flange, using silicone caulk to
seal the pipe to the flange. The pipe may protrude into the furnace up to 1 inch past the flange. For
increased rigidity, a self-tapping screw may be installed thru the flange into the PVC pipe.
H. CONDENSATE DRAIN LINE & TRAP ASSEMBLY
1. The following diagrams depict typical condensate drain and trap connections for the furnace models series
CLHS1 and CLHX1, refer to the illustrations in Figures 8a-8b and 9.
NOTICE: If the 11/16 inch tubing is difficult to slide through the rubber grommet, spray some mild soap or
light oil (such as WD-40) on the tube prior to pushing through the grommet to serve as a lubricant. Wipe off
excess after installation.
