Clearances

Clamps
Both the exhaust line and air intake hose are
supported by clamps which are attached to the wall.
A wall fixture can be used to offset the clamp from the
wall. Use Screw B to attach the wall fixture to the
wall. If the wall fixture is not used then use Screw A
and the nut to attach the clamp to the wall.
The air intake hose should always be underneath the
exhaust line so that in case the air intake hose sags it
will not come into contact with the exhaust line.
Installing the Exhaust Line
The exhaust line is connected between the bent pipe
at the rear of the furnace and the exhaust port on the
flue manifold.
To connect exhaust pipes with other straight pipes or
bends, fit the male end into the female end. Use pipe
stopper A to clamp the connection.
Use pipe stopper B to fix the length on the adjustable
exhaust pipes. Do not extend these pipes beyond the
red line.
Do not cut the exhaust pipe. Use the adjustable
pipes if necessary.
To bend the elbow, insert exhaust pipes into both
ends for additional leverage. Bend to desired angle.
Do not straighten the bent pipe attached to the
appliance.
Connecting the Air Intake Hose
The air intake hose is connected between the air
connection at the rear of the furnace and the air intake
port on the flue manifold.
Push the air intake hose onto the flue manifold and
secure with the plastic cable tie.
Join air intake hoses by screwing the hose joint half of
its length into the air intake hose and then screwing
another air intake hose into the hose joint.
Do not cut the intake hose. Cutting
NOTICE
the intake hose may result in noise.

Use the pipe stoppers, connectors, clamps, and screws according to these instructions in
