Carbon Monoxide warning
Follow all the local and skate codes or in
absence of local and sate codes the
„National Fuel Gas Code"', ANSI Z223.1
UNFPA 54)- latest edition to properly install
vent S]IStE:RI.
Failure to de so can result in death,
explosion, or carbon monoxide poisoning.
Important: Air for combustion and ventilation must not
come from a corrosive atmosphere. Any failure due to
cflrras�ve elements in the atmosphere is excluded from
warranty coverage.
Vent Paipe Systew.
This i5 a direct vent water heater which draws its combustion
air from outside of the structure and exhausts all products
of combustion to the outside of the structure.
Through -the -wall installations. require locating the wader
heater next to an outside wall. All necessary components
ars supplied for the standard through -the -wall installation.
Optional vertical and horizontal extension kits are available
for installations that exceed the standard horizontal and
vertical distances see table at right}. Only one vertical and
one horizontal kit can be used on the same installation.
Through the Wall Venting
1 _ Make sire a proper location has been selected for the
water heater ins#aflation. Consider the failvwing:
e Water piping
Gas Piping
e Access for service
e Proper clearance for combustibles
• Drainage for the temperature and pressure relief
valve and drain fan.
• Vent cap termination
2.. Determine the "A" dimension for your specific water heaterby referencing figure 7. Cut a 6 inch opening through the
wall in the focation as shown. Determine the location of
e€eetrical wiring, pips, or wall Muds before cutting.
NOTE} Installations requiring an "A" dimension vertical
height) greater than what is shown as standard in the table
will reaquire the use of a vertical extension kit See "Vertical

3. If you are not using the vertical extens�or� kit, pace the
3" �Ibow on the flee pipe re�du�er on the air box and poilnt
it in the desired direction (See Figure 8). Pressit firmly
downward until seated, Drill 4 hales 90° apart with a 118"
drill bit and fasten the four #8 sheet metal screws provided.
Apply silicone sealant to the joint. Install the 5°' elbow
over the 3" elbow and seat it info the calcar on the air box.
Drill 4 holes 90° apart with a 118" drill bit and fasten the
four #S sheet metal screws provided. Apply silicone
sealant to the joint. Place the inner wall cover platy over
the 5" elbow. This plate will be positioned layer.

4. Expend the 3" telescoping pipe to its maximum length.
Place the smaller section onto the 3" elbow at feast 1 and
1/2 inches (See Figure 9). DMI two holes 1800 apaq
and secure with the two #8 sheet metal screws provided.
Apply silicone sealant to the joint,.
5. Attach the larger section of the 5" telescoping pipe to the
flange on the outer wall plate (See Figure 9j. Drill holes
90° apart with a 1/8" drill bit and fasten with four 48 sheet
metal screws (provided), Apply, silicone sealant to the
seam.
6. Extend the a" telescoping tube to its maximum length.
From outside of the building, inset a 5" tube/outer wall
plate assembly through the opening in the exterior wall
and onto the 5" elbow See Figure 9}. Seat the base of
the ower wall plate onto the exterior wall. Apply silicone
sealant between the plate and the exterior wall.
7. Place the 3" tube located in the gent cap into the end of
the 3" telescoping tube (See Figure 10}. Drill two holes
180° apart with a 'l18" drill bit and secure with two #$
sheet metal screws. /apply sealant to the joint_ Sept the
cap against outer wall plate with the ward "HQT'I in an
upright position.
8. Secure the vent cap./outer wall plate assembly to the
exterior wall with the four 1 and 112" screws provided
(See Figure 10). Varying wall structures may require a
different type of screw anchor. To prevent rein from
entering the water heater cent pipe, the 5" tube should
be sloped downward towards the wall 114" per foot.

. Position and fasten the inner I I plate to the inside wall
using n appropriate fastener for the p ifis wall
construction. Apply silicone sealant between the inner
wall plate and the inside wall.
10. Make certain the 5" telescoping pipe has been fully
engaged onto the 5 inch elbow. Drill two 118" hales 180'
apart at the junction of the two joins. Secure with four
#8 sheet metal screws and app[y silicone sealant to the
seams. Made sure all the 5" pipe joints are sealed including
the joint to the collar on the water heater's air supply fax
(See Figure 9}.
Optional Vertical Extension Kit
Installations requiring dimension "Pr'° to be greater than X2.75"
(40 Gallon) or 71.00" {5a Gallon} will require the use of the
optional vertical extension felt. The maximum height of the
"A" dimension cannot exceed 98 inches. if the "A" dimension
for your application is less than 98 inches, you will have to
cut the 3 and 5 inch pipes in the vertical extension kit to the
correct length. For example, if your applicable "A" distance
is 80 inches, then 98 inches - 80 inches = 18 inches. Therefore,
you will need to out 18 inches from bath the 3 and 5 inch
vertieal extension pipes.. DO NOT CUT THE CRIMP'ED END
OF THE 5 INCH PIPE.
After cutting both the pipes to the proper sire, place the 3"
vertical extension pipe over the flue pipe reducer an the
upper air box and press it firmly downward until seated. Using
a level, make sure the extension tube is poinding straight up.
Drill 4 holes 90° apart with a 1/812, drill bit and fasten with four
#8 sheet metal screws (provided). Apply silicone sealant to
the seam.
Place the uncrimped end of the 5 inch extension pipe over
the 3 inch extension pipe and seal it onto the collar on the
air box. Making scare the 3 inch extension p6pe is centered
in the 5 inch pipe, drill four holes 900 apart with the 118" drill
bit and fasten with flour 98 sheep metal screws (provided).
,Apply silicone sealant to the seam.. Plage the flared end of
the 3 inch elbow over the 3 inch extension pipe and press
it firmly downward until seated. Drill four hobs 90° apart with
the 118" drill and fasten with four #8 sheet metal screws
(provided). Apply silicone sealant to the seam.
Install the 5 inch elbow over the 3 inch elbow and seat it
down onto the crimped end of the 5 inch extension pipe_
Temporarily place the 5 inch telescoping pipe onto the 5 inch
elbow and adjust it to gine a 114 inch per boat downward
slope to the outside wall Secure the 5 inch elbow to the
extension pipe by drilling four holes 9J° apart with the 118
drill and inserting four #8 sheet metal screws. Appy silicone
sealant to the joint. Place the inner wall colder Mate over the
5 inch elbow. This date will be positioned later. Proceed to
step 4.
THROUGH THE ROOF VENTING*
1 . tenter the heater directly ender the roof opening.
This vett system must be installed vertically only.
2. All the pipes needed to assemble the vent are included
in the kit. Do not add to the length of the gent system.
The total height is lim,ited to 15 feet on a 54 -gallon
heater (See Figure 11). The 4U -gallon heateris 8
and 1 14" shover. The total 15 -foot height mush stick
through the roof a minimum of 2 feet. if the freight
needed is less than 15 feet, determine the height
needed and subtract that from 15 feet. That amount
needs to be cut off one of the. 3" pipes and 5" pipes.
Cut the nen-dared end of the 372 pipe and the uncrimped
end of the 5" pipe.
3. Assembly the kit from the fop down starting with the
termination. Attach a 3" pipe using 4 #8 sheet meta!
screws 90° apart and seal the joint with sealant. Tien
attach the 513 section in the same manor.. Drill SIS"
pilot holes for the screws. Continue until the fill length
is assembled. Put the telescoping 5" section on [ash.
4. Place the heater in pasitlon, feed the vent assembly
down through the roof with the flashing in place, and
allow it to rest with the 3" pipe attached to the 3" vent
terminal on the heater. Use screws and sealant to
secure that joint. Extend the 5" telescoping section to
connect to the 5" termination on the heater. Secure
that joint with screws. 5eaf that joint and the sfIding
joint with silicone to make ars airtight assembly.
5. Secure the flashing and gent assembly to the roof.
