6. Insert the bent joint to the exhaust opening of the flue pipe. Cut the inlet hose for desired length if necessary.
Attach the L-shaped hose to each end of the inlet hose and attach the L-shaped hose to the intake opening of
the flue pipe. Secure the L-shaped hose to the intake opening with the hose band. Plug the unused exhaust
(metal cap) and intake (rubber cap) opening with the caps provided with the heater. Make sure the caps fit
tightly onto the opening (See Fig. 10).
NOTE: If the inlet hose is not smoothly inserted into the L-shaped hose, apply water or soap suds to the inlet
hose. Do not use grease on air intake.
7. In case the circuit board cover gets in the way of the connection of the standard flue pipe, use the exhaust
extension pipe (S) for the exhaust outlet opening of the heater (See Fig. 11).
