Toyotomi Oil Miser OM-148 Installation Manual page 11

NOTE: Make sure wall thickness is not greater than 10-1/2 inches.
Flue pipe can be installed through any standard building materials. Please ask your local dealer
or distributor for more details.
3. For standard installation, position the hole for the flue pipe.
NOTE: The water heater should be installed on a sturdy floor that is level and flat.
4. Cut the hole for the flue pipe from inside the room. Use a 4-3/4" diameter hole saw attached to an elec-
tric drill. The opening on the inside wall should be slightly higher than the outside opening (approxi-
mately 1/4") so that the flue pipe will slope slightly downward (approximately 3 degrees) after it is
installed. This will enable condensed moisture to drain from the flue pipe to the outside and prevent
rain or snow from entering from outside after installation.
5. Install the inner flange and the flange gasket to the inner flue pipe and insert the inner flue pipe through
the wall hole from inside the room. Make sure the arrow on the inner flange is pointing up and secure
the securing band with a screw and a nut through two holes of the fixing band. Secure the inner flue
pipe to the wall with the four screws provided with the unit.
6. Install the flange gasket to the outer flue pipe. Secure the outer flue pipe to the wall by turning it clock-
wise. This locks the two halves together.
NOTE: Make sure to secure the outer flue pipe well.
7. Insert the flexible exhaust pipe to the flexible bent joint until it locks. Insert the flexible bent joint to the
exhaust opening of the inner flue pipe until it locks.
