Installation Of Unit And Flue Pipe - Toyotomi Oil Miser OM-180 Installation Manual

INSTALLATION OF THE UNIT AND FLUE PIPE
SAFETY TIPS
WARNING:
1. The flue pipe opening must be fully exposed to outside air. Do not vent into a garage, basement, under
the floor, or into any enclosed area.
2. Do not install the flue pipe in close proximity to other objects or materials.
3. Before making a hole in your wall for the flue pipe, make sure the area is free of electrical wires, gas
pipes and other obstacles.
4. Do not install the flue pipe where it will be exposed to heavy snow, collected leaves, or strong winds.
IMPORTANT: In areas of heavy snow fall, ground surface clearance must be increased according to
average snow falls.
In open areas with strong wind, a wind breaker may be necessary.
5. Do not install the flue pipe below the water heater.
6. The exhaust pipe should be properly installed and connected. Aluminum tape may be used for sealing
exhaust pipe connections.
7. Always cover the exhaust pipe with the insulating cloth cover.
8. If installed in building without an eave, a non-combustion eave should be installed.
CAUTION:
Total length of the extension pipe between the water heater and the flue pipe must
be no greater than 10 ft. with a total of three bends.
NOTE: When using extension pipes always cover the exhaust pipe with the insu-
lating cloth cover.
INSTALLATION OF UNIT
1. Install the unit on a noncombustible surface in a stable position. If installing on a combustible floor, the
unit should be raised up off the floor to prevent contact with combustible materials by using brick, con-
crete block or similar non-combustible material.
If minimum clearances between the unit and combustible construction are maintained, no ventilation
openings are needed in the closet door when installed in a closet.
