SAFETY WARNINGS

WARNING!
It is imperative that the water heater tank be filled with water before operating
the water heater. Operation of the water heater without water in the tank may result in damage
to the tank and/or controls. This type of damage is not covered by the limited warranty.
WARNING!
Hydrogen gas may result if you have not used this heater for two weeks or
more. HYDROGEN GAS IS EXTREMELY FLAMMABLE. To reduce the risk of injury under
these conditions, open the hot water faucet for several minutes at the kitchen sink before
you use any electrical appliance connected to the hot water system. If hydrogen is present,
you probably will hear an unusual sound such as air escaping through the pipe as the water
begins to flow.
Hydrogen gas may be present even after water has been drained from the tank. Open faucet
at sink and allow system to vent for several minutes (5-10 minutes).
Do not smoke or have any open flame near the open faucet. Do not attempt to light pilot or
main burner. On DSI models, be sure the switch is "OFF".
Should overheating occur, or the gas supply fail to shut off, shut off the manual gas valve to
the appliance before shutting off the electrical supply.
Do not use this appliance if any part has been submerged under water. Immediately call a
qualified service technician to inspect the appliance and to replace any part of the control
system and any gas control that has been submerged under water.
Do not alter the operation of your water heater nor change the design/construction of your
water heater. Accessories are being marketed for RV products which we do not recommend.
For your safety, only factory authorized parts are to be used on your water heater.
Periodically inspect the vent for obstructions or presence of soot. Soot is formed whenever
combustion is incomplete. This is your visual warning that the water heater is operating in
an unsafe manner. If soot is present, immediately shut the water heater down and contact
your dealer or a qualified service person.
When considering add-on rooms, porch or patio, attention must be given to the venting of
your water heater. For your safety, do not terminate the vent on your water heater inside add-
on rooms, screen porch or onto patios. Doing so will result in products of combustion being
vented into the rooms or occupied areas.
Never operate the heater if you smell gas. Do not assume that the smell of gas in your RV
is normal. Any time you detect the odor of gas, it is to be considered life threatening and
corrected immediately. Extinguish any open flames including cigarettes and evacuate all
persons from the vehicle. Shut off gas supply at LP gas bottle. (See the Safety notice on
front cover of this manual.)
NOTE: Always open both the cold and hot water faucets when filling vehicle water tank to
allow air pockets to be forced out of the water heater. When water flows from the faucets,
close both faucets.
WARNING!
Do not store or use combustible materials or liquids near or adjacent to
this heater. The appliance shall not be installed in any location where flammable liquids or
vapors are likely to be present.
Be sure the power is "OFF" to the water heater ignition system during any type of refueling
and while vehicle is in motion or being towed.
The thermostat on your water heater is not adjustable. It is a temperature sensing limit
designed to maintain a water temperature of 130̊ F (54̊ C ). Water temperatures over 130̊ F
(54̊ C ) can cause severe burns instantly or death from scalds; therefore, be careful when
using hot water. Children, disabled and elderly are at highest risk of being scalded. Always
feel water before bathing or showering.

INSTALLATION INSTRUCTIONS

Minimum clearance from combustible construction on sides, top, floor and rear =
0 inches. Provide room for access to rear of heater for servicing.
Provide an opening flush with floor in outer wall of coach as shown. Wall of
coach should be framed as shown in Figure 1 SW6DEL; Figure1A SW10DEL/
SW12DEL/SW16DEL. Maintain inside dimensions listed below. Do not install on
carpet unless the carpet is covered by a metal or wood shield covering the entire
area underneath the water heater. If you prefer, you may cut away the carpet from
this area.
INSTALLATION USING HINGED DOOR
(See Figure 3 SW6DEL)
A. Position heater into framed opening as illustrated.
B. On mesa or yoder type sidewalls, flatten the wall area around the opening.
C. Caulk around framed opening (trailer skin) as illustrated.
D. Lay a bead of silicone caulking (or suitable caulking) around the inner edge of
the control housing (top, bottom and sides). See detail "A" in ilustration. This
will seal frame to control housing.
E. Apply a bead of silicone caulking (or suitable caulking) around back side of
door frame. See detail "A" in illustration. This will seal frame to coach skin.
F. Fit the door frame into control housing (over the caulking already applied) and
pull frame tight to control housing using the three (3) No. 8-15 x 3 1/2" screws
provided.
G. Push water heater into framed opening until back side of door frame (now
attached to control housing) is against the side of the coach and firmly attach
with screws around the perimeter of the frame. NOTE: The two (2) holes in
bottom of frame identified as "A" in Figure 3 are also used to mount door hinge
to the frame.
H. Install chocks, one on each side of water heater, as illustrated in Figure 1B.
I. Attach door to frame as illustrated.
J. Close the door so that the door latch protrudes through the slot in the door.
Turn latch 90 degrees to fasten door.
K. The module board on model SW6DEL, is not secured to the water heater. It
is to be permanently mounted by the installer.
The module board must be mounted so it is accessible for service yet out of
way of children. It should be located in a place where it cannot be subjected to
moisture, cleaning chemicals, flammable vapors and liquids, etc.
The board and all wiring to the board must be protected in order to prevent
damages and accidental contact with these parts. The module board may be
mounted with two (2) No. 6 x 5/8 screws or other suitable hardware.
INSTALLATION USING FLUSH MOUNT
FRAME & DOOR
(See Figure 2 SW6DEL; Figure 2A SW10DEL, SW12DEL, SW16DEL)
A. Position heater into framed opening as illustrated. Slide unit into opening until
the front of the control housing is flush with the exterior coach skin.
B. Secure the control housing to the coach wall (framed opening) at the top
and sides of control housing compartment using screws or other suitable
fasteners. Recess the screws or fasteners back far enough from the front
edge of control housing (approximately 1 1/2") in order to clear the flange on
door frame. The door frame, when installed, must not overlap onto screw or
other fastener head. If due to the wall thickness, it is not possible to secure
the water heater without covering the fastener head with the door frame, it is
important to not over tighten the fastener and distort the control housing. Over
tightening of the fastener may cause water heater leaks between the control
housing and the door frame.
NOTE: Caulk around screw or fastener heads to assure water tight seal.
