has been installed in the flue tube. If the flue baffle
is not present, immediately contact the dealer where
the water heater was purchased. Never operate the
water heater without the flue baffle installed.
To install the drafthood, place it over the flue opening
on the top of the water heater. When installing the draft-
hood do not alter it in any way.
UG30 and UG40 Models
Line up the holes in the drafthood’s legs with those of
the water heater’s top and secure the drafthood using
the two (2) sheet metal screws provided (see Figure 7a).
UG50 and UG60 Models
Line up the legs of the drafthood with the holes with
those of the water heater’s top and snap into position.
Then insert the two (2) sheet metal screws provided
into the same holes to secure legs down into place
(see Figure 7b)
.
Venting System
The venting system must be attached to the draft-
hood to connect the water heater to the gas vent
or chimney. The vent pipe connecting to the water
heater must be of the same size as the drafthood.
It is highly recommended to install this water heater
on a separate venting system from other appliances. In
some installations, proper venting may require the use
of a larger diameter vent pipe and/or combined vent-
ing with other appliances. Consult the vent tables in
the CAN/CGA B149 in Canada and/or the National
Fuel Gas Code, ANSI Z223.1 in the United States to
correctly size the vent pipe.
When connecting the vent pipe to the water heater
the following instructions must be followed:
• Install the vent pipe in such a way as to avoid any
unnecessary bends that could create resistance to
the flow of combustion gases.
• The length of the vent pipe must not exceed 75%
of the vertical vent height, in no case exceeding 20
feet (6,1 m).
• All horizontal runs must have a minimum rise of
1/4 inch per foot (21 mm/m) of run (See Figure 8).
• All joints must be securely fastened with sheet
metal screws or other approved means.
• All single wall vent piping must maintain a mini-
mum of six (6) inches (15.2 cm) of clearance from
combustible materials.
• Venting systems made with single wall piping can-
not pass through any attic, inside wall, crawlspace,
confined space, or any floor.
• The vent piping must be accessible for inspection,
cleaning, and replacement.
When the installation is complete, visually inspect
the venting system to make sure that all joints are
properly connected and all instructions have been
followed. Failure to properly install the venting
system could result in property damage, personal
injury, or death.
Water Piping
Refer to Figure 8 for a typical installation. Use of this
layout should provide a trouble free installation for
the life of the water heater. Before making the plumb-
ing connections, locate the COLD water inlet and the
HOT
water outlet. These fittings are both 3/4” N.P.T.
male thread. Make sure that the dip-tube is installed
in the cold water inlet. Install a shut-off valve close to
the water heater in the cold water line. It is
recommended that unions be installed in the cold and
hot water lines so that the water heater can be easily
disconnected, if servicing is required.
When assembling the hot and cold piping, use a
good food grade of pipe joint compound, and ensure
all fittings are tight. It is imperative that open flame is
not applied to the inlet and outlet fittings, as heat will
damage or destroy the plastic lined fittings. This will
result in premature failure of the fittings, which is
not covered by the warranty.
