1. UPFLOW GAS FURNACE
a. Apply gasket material (duct seal eld supplied) to ALL
mating surfaces between the furnace and the coil case.
b. Set the coil case on top of the furnace. Connect the
ductwork to the coil case using eld supplied screws.
See Figure 2.
c. Secure the coil case to the furnace and seal for air
leaks as required.

This coil is pressurized with 8-12 psig of dry air. Do
not stand directly in front of the coil connections when
removing sealing plugs. If no pressure is released, check
for leaks.
1. DOWNFLOW COIL CONVERSION
On 4PXCDD60BS and 4PXCDU60BS, installing the water
diverter ba󰀪es is required for water management in downow
installations. Install the two outer water ba󰀪es closest to the
drain pan using the provided 5/16" hex screws. See Figure 3.
2. DOWNFLOW GAS FURNACE
When a coil is used with a downow furnace, a subbase is not
required between the coil case and combustible ooring
a. Place the coil case on the furnace supply air plenum.
b. Secure the coil case to the plenum.
c. Set the furnace on top of the coil case, making sure that the
back side of the discharge opening is snug up against the
duct ange at the top rear of the coil case.
d. Secure the coil case to the furnace and seal for air
leaks as required.
3. DOWNFLOW GASKET INSTALLATION (OPTIONAL):
For unusually humid applications that expect prolonged operation
above 70% RH, it is recommended to use the BAYGSKT001A0
gasket kit to prevent water from forming on the bottom of the drain
pan and dripping into the supply ductwork.
a. Lay the coil on its back side.
b. Locate the 4" wide gasket material found in BAYGSKT001A0.
c. Attach the 4" gasket material to three sides of the bottom of
the drain pan as shown. Make sure to start by matching up
the edge of the gasket material to the inner edge of the drain
pan by the coil ns and working outwards.
d. The gasket material can be cut or ripped easily so that it can
be tailored to t. The gasket material must cover the three
sides along the entire length of the coil as shown in Figure 4.
