CONDENSATE DRAIN
FOR HORIZONTAL
(RGJF) INSTALLATION
WARNING
DEDICATED HORIZONTAL (RGJF)
MODELS ARE SHIPPED WITHOUT
A DRAIN TRAP ATTACHED. IT
MUST BE ATTACHED (AS
DESCRIBED BELOW) IN THE
FIELD. FAILURE TO INSTALL THE
DRAIN TRAP AS DESCRIBED CAN
CAUSE THE FURNACE TO SHUT
DOWN UNEXPECTEDLY.
NOTE: The following steps should
take place with the furnace in the
horizontal position.
Refer to Figure 37 for Steps 1-8.
1. Locate the parts bag in the burner
compartment.
2. Remove the red vinyl covers that
cover the vent drain and heat
exchanger drain (see Figure 38).
3. Fill the trap assembly
cup of water.
4. Attach the gasket H
assembly so that the gasket holes
on the gasket line up with the
holes on the trap assembly.
5. Insert the trap assembly with gas-
ket up through the existing hole in
the jacket and secure from inside
the jacket. Use two screws pro-
vided. Screw down into the two
"ears" molded into either side of
the trap. Snug the trap assembly
against the furnace jacket com-
pressing the gasket slightly to
eliminate any air leaks. Do not
overtighten!
6. Attach the black molded rubber
90° elbow to the straight spout
I
on the trap top using a black
nylon clamp . Attach the other
J
end of the rubber elbow to the
spout located on the exhaust
K
transition using a black nylon
E
clamp.
7. Attach one end of the horizontal
ribbed tube to the collector box.
L
Clamp the hose tight with black
nylon clamp. Then attach the
other end of the ribbed tube to the
45° elbow molded into the top of
the trap assembly. Clamp the
hose tight with black nylon clamp.
The horizontal ribbed tube is 6.7"
in length.
IMPORTANT: Tighten all clamp
connections with a pair of pliers
and check for leaks after conver-
sion is complete.
8. IMPORTANT: There are two
options when choosing a height
for the condensate riser:
CONDENSATE OVERFLOW:
With a 1 3 ⁄ inch riser installed
4
above the tee, a blocked drain will
result in overflow from the riser.
38
FURNACE SHUTDOWN: To
cause the furnace to shut down
when a blocked drain is present,
install a riser which is a minimum
of 5 1
in an attic, crawlspace or other
area where freezing temperatures
may occur, the furnace drain can
freeze while shut off for long peri-
ods of time. Provisions must be
made to prevent freezing of con-
densate.
Use a solvent cement that is com-
patible with PVC material.

FILLING THE TRAP
FILL THE TRAP ASSEMBLY WITH
WATER BEFORE OPERATING THE
FURNACE. Do this by removing the
drain hose from the trap or from the
connection to the secondary coil.
Pour about a cup of water into the
vent trap. Any excess water flows into
the house drain when the trap is full.
