CAUTION:
If possible, do not install the water heater to where the vent can be covered or
obstructed when any door on the trailer is opened. If this is not possible, then the travel of the
door must be restricted in order to provide a 6” minimum clearance between the water heater
vent and any door whenever the door is opened.
CAUTION:
Due to the differences in vinyl siding, this appliance should not be installed on
vinyl siding without first consulting with the manufacturer of the siding or cutting the siding away
from the area around the appliance vent.
CAUTION:
In any installation in which the vent of this appliance can be covered due to the
construction of the RV or some special feature of the RV such as slide out, pop-up etc., always
insure that the appliance cannot be operated by setting the thermostat to the positive “OFF”
position and shutting off all electrical and gas supply to the appliance.
CAUTION:
Do not install this appliance to where the vent terminates below a slide-out. This
appliance is not to be installed under any overhang. It must be free and clear of any type overhang.
This appliance shall be installed only by authorised persons and in accordance
with the manufacturer’s installation instructions, local gas fitting regulations,
electrical wiring regulations, local water supply regulations, AS/NZS 5601.2; gas
installations and any other statutory regulations. Installation shall be in accordance
with AS/NZS 3500.4.
1. The appliance shall be disconnected from the gas supply piping system during
any pressure testing of the system.
2. The appliance and its gas connections shall be leak tested before placing the
appliance in operation.
3. All air for combustion must be supplied from outside the structure. Air for
combustion must not be supplied from occupied spaces.
4. This unit is a balance flue heater.
5. Discharge pipe must be mounted at the pressure relief valve and installed
through floor line of caravan or motor home, and must be left open to free
air so as water can escape if required and is to be installed in a continuously
downward direction and in a frost-free environment. For convenience, a break
-thru grommet has been provided in the bottom of the control housing. The

reducing valve is not installed.
INSTALLATION INSTRUCTIONS
Keep the heater and flueway at least 25mm clear of anything that is combustible,
like walls, cupboards and timber.
Provide an opening flush with floor in outer wall of coach as shown. Wall of coach
should be framed as shown in Figure 1. Maintain inside dimensions listed below.
Do not install on carpet unless the carpet is covered by a metal shield at least
50mm greater than the width of the water heater.
INSTALLATION USING HINGED DOOR
(See Figure 2 for models SW4DEA/SW6DEA) (See Figure 2A for models SW4DA/SW6DA)
A.
In some limited accessibility applications, the chocks as illustrated in Figure
1A must be installed prior to setting water heater into position. Install chocks,
one on each side of water heater, as illustrated in Figure 1A.
B. Position heater into framed opening as illustrated.
C. On mesa or yoder type sidewalls, flatten the wall area around the opening.
D. Caulk around framed opening (trailer skin) as illustrated.
E. 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 illustration. This
will seal frame to control housing.
F. 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.
G. 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.
H. 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 2 are also used to mount door hinge
to the frame.
I. If already installed, confirm chocks are supporting the water heater correctly. If
not already completed, install chocks, one on each side of water heater, as
illustrated in Figure 1A.
J.
Attach door to frame as illustrated.
K. Close the door so that the door latch protrudes through the slot in the door.
Turn latch 90 degrees to fasten door. Be sure the extension on the flue
protrudes through the door a minimum of 15 mm.
L. The module board is not secured to the water heater. It is to be permanently
mounted by the installer.
The module board must be mounted to where 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.
MAKING WATER CONNECTIONS
WARNING!
A tempering valve or other similar device must be installed between the
outlet of the hot water service and any faucet.
Connect water lines to rear of unit. Suitable fittings must be used in rear of hot
and cold water connections. DO NOT glue metal fittings. This will void warranty.
NOTE :
Inside each fitting is a suitable fill tube installed by manufacturer. Its purpose is to
enhance water circulation. DO NOT REMOVE THE PLASTIC FILL TUBES.
Fill tank with water. Always open both the cold and hot water taps when filling vehicle water tank
to allow air pockets to be forced out of the water heater. When tank is filled, turn off taps and
check for leaks at connections. After leak testing, drain water from tank.
